Getting To Know Your Hair–pH & Hair

So far, we’ve discussed what healthy hair is and what three things are key in maintaining healthy hair – moisture, protein and pH. I’ve talked about the first two, moisture and protein and how to maintain the correct moisture/protein balance with regular wet testing. Today i’m continuing the ‘Getting To Know Your Hair’ series with a brief outline of what pH is and how it affects the health of our hair.

What is pH?

pH stands for ‘potential of hydrogen’ or ‘hydrogen strength’ and refers to the acidity or alkalinity of an aqueous (water based) solution relative to the concentration of hydrogen ions present. The level of pH is measured on a logarithmic scale of 0 – 14 with 0 being the most acidic and 14 being the most alkaline. In the middle we have pH 7 which is considered neutral as it has an equal balance of acidity and alkalinity. Water has a pH of 7 (hard water can measure pH 8!). pH 0 – 6.9 are acidic in nature and pH 7.1 – 14 are alkaline (base or caustic).

pH on a logarithmic scale is measured in multiples of 10 so every number on the scale is 10x more alkaline or acidic than the previous number. Example: pH 6 is 10x more acidic than pH 7, pH 5 is 10x more acidic than pH 6 and 100x (10×10) more acidic than pH 7. pH 8 is 10x more alkaline than pH 7 and pH 9 is 10x more alkaline than pH 8 and 100x (10×10) more alkaline than pH 7. It’s a little confusing i know, but it does help to know this (honestly).

What pH is Our Hair?

Our hair and skins pH measures between 4.0 – 5.5 so our hair is acidic in nature. In order to maintain optimal hair health we should try and keep our hair within this range.

How pH Affects Our Hair

pH greatly affects the way in which our hair looks, feels and behaves.

 

How Acidity Affects Our Hair

In it’s optimal pH range of 4.0 to 5.5 the cuticles of our hair lie flat against one another contributing to a smooth look and feel and allows light to bounce off well, giving our hair lovely shine or sheen. Closed cuticles protect the shaft from external damage and allows the strands to move around each other without causing damage. If we decrease the pH of our hair further, then the cuticles continue to tighten and tighten. Solutions or products with a pH lower than 3 will begin to corrode or eat away at the hair & scalp causing damage.

How Alkalinity Affects Our Hair

If we raise the pH of our hair above 5.5 the shaft begins to swell and the cuticles will begin to lift or open. Raised cuticles will allow more moisture into our hair but will also allow more moisture out. Lifted cuticles expose the hairs cortex and provides limited protection. Hair in this state is considered weak and susceptible to further damage. Lifted cuticles cause the hair to look dull and rough and each strand can tangle on the next causing more damage to the cuticle layer. The higher the pH the more our hair swells and our cuticles lift incurring more and more damage. Solutions or products with a pH of 10 or more will begin to dissolve the hair and scalp causing damage. Permanent hair dyes and relaxers are extremely alkaline (pH values between 10 and 13) and work by lifting the cuticles so the chemicals can deposit onto and alter the cortex/main structure of the hair.  Highly alkaline solutions weaken the disulfide bonds in the hair and can alter it’s structure permanently. 

Maintaining Healthy Hair With pH

Our goal here is to maintain the hairs optimal pH range of between 4.0 and 5.5 and thus keep it nice and healthy. All products containing water have a pH value and it’s important that our water based products such as shampoos, conditioners, leave-ins and moisturisers be within this range. Remember, water is 100 – 1000 times more alkaline than our hair so even a quick warm water rinse will cause the cuticles to lift slightly. If we dry our hair and apply oil or butter straight onto our hair after rinsing with warm water, the cuticles will remain open causing a slight feel of roughness and less sheen or shine. We should always try to restore or rebalance our hairs pH. It’s important, then, to use a water based, pH balanced (acidic) leave-in or moisturiser after washing our hair to bring the pH back down and close the cuticles before sealing with an oil or butter. A final rinse of diluted ACV (Apple Cider Vinegar) also serves this purpose. Aloe Vera is also a great ingredient choice for hair moisturisers and spritzes as its pH value is around 4. This way we ensure our cuticles are closed, that moisture is retained well and our hair is stronger and less susceptible to damage.

The last post in this series will be on porosity and how it affects our hair, including how to correct any porosity issues.

Until next time!

Interesting pH Results

I just thought I’d show you these pH results that i found so interesting.

Whilst making the tea for my Leave-in conditioner i decided to test the pH of it. I used bottled water to make the tea as my filter is not working so well at the moment.

pH of Bottled Water the pH of this water was a 7

pH of Tea The pH of the tea measured a 4.5!

 

How is that possible? It’s the same water. Obviously the herbs have changed the pH to a more acidic range. Or was it the metal pot i used to boil it in? Not sure, but it’s very interesting nonetheless and that is probably why my leave-in conditioner showed a consistently low pH range, even without the citric acid.

 

Just thought i’d share that with you.

Leave-In Conditioner – Take 2 (Updated)

I re-made my leave-in conditioner today as I needed to tweak the recipe a little. My notes on the last Leave-in were:

Notes

Conditioner is too strengthening (makes hair slightly hard if left ‘out’)
Has too much slip
Not creamy and thick enough
Not enough long term conditioning
Too much humectant (makes hair frizzy after a while)
To remedy this I will:

  • Reduce the amount of Hydrolysed Wheat Protein
  • Reduce the amount of Humectants (Glycerin and Honeyquat)
  • Reduce the amount of Panthenol
  • Reduce the amount of Guar Conditioning gum
  • Increase the amount of BTMS
  • Increase the amount of oils
  • Increase the amount of Lamesoft
  • Reduce Aloe Juice (as pH was consistently low)
  • Add in citric acid as a precautionary pH stabiliser
  • Increase Herbal Tea
  • Will not add extra Aloe Juice this time (even if it appears thick)

And that’s exactly what i did. I’m not going to repost all the information and directions as you can find that in the first post, but i did take pics of all the steps (I made sure i charged my camera battery). If anyone wants the adjusted recipe i can give it to them, otherwise it’s blah, blah isn’t it? lol.

Onion Juice Treatment & Curl Harmony – Week 2

This week i tweaked the onion juice treatment slightly. I also took some pictures of what i did as i said i would in my previous post.

Onion The Onion i used

My Juicer I juiced the onion in my Champion Juicer

Muslin Then strained it through a muslin cloth to get rid of any little bits

Onion Juice Here is the resulting juice

Onion & Bentonite Next i added in some bentonite clay

Mixing And whisked it in until smooth. I used 2 teaspoons in all, adding it in 1/2 a teaspoon at a time.

pH Test The pH of the mix was between 6.5 and 7. This is considered acceptable for hair and scalp usage as it’s the same pH as water… But i wanted to bring the pH a little closer the scalps pH which is between 4.5 –5.5

pH Test with ACV So i decided to add in some ACV (Apple Cider Vinegar). Just a 1/4 teaspoon. That brought the pH right down to between 5 and 5.5. The darkness of the bentonite clay made it hard to read it properly but it was definitely in that range.

Applying HELLO! lol. This is what it looked like once i had applied it to my scalp and hairline.

Plastic Bag I then put a plastic bag over my head (Waitrose this time. ha) and left it on for about 30 – 45 mins

Curl Harmony Review

 

I used the Curl Harmony Cleansing Cream to wash my hair. I started by rinsing my hair thoroughly and then took down one of the sectioned twists. I let the water run through it some more before applying a liberal amount of the cleansing cream to the section. I rubbed my scalp well and massaged it into the ends and rinsed it out. I then applied some more of the Cleansing Conditioner and detangled, first with a wide tooth comb and then with my modified Denman brush. It detangled really well. I was very impressed. I think i like it more than the Hydrating Conditioner. But maybe that’s because i didn’t use enough of it last time. Because of the onion treatment i wasn’t scrimping with the Conditioner as i wanted to rid the smell as much as possible

Shed Hair Shed hair from detangling. I lost a little down the drain but this is most of it.

Cleansing Cond I hope you can see. I wanted to show you how much Cleansing Conditioner i used. I could make it last another 3 washes i think.

After detangling i retwisted the section, still with the conditioner in and repeated the process for the remaining 3 sections. Once i had finished detangling i rinsed my whole head with the twists in to remove the remaining conditioner. I towel dried and then DC’d with the…

CH Deep Cond Intensive Repair Deep Conditioner

Spoonful of DC I took 2 heaped teaspoonfuls of the conditioner and mixed it into some honey and olive oil.

Mixed DC Here’s what it looks like mixed together. Still super thick and creamy. Lovely.

Applying DC I applied it to my hair in sections. Taking down the twist apply the DC and re-twisting. Here’s what it looked like. If you look closely i haven’t applied it to the roots. I didn’t want to coat my scalp with it. I didn’t want any conditioner residue left on my scalp.

I covered my hair with another plastic bag (Tesco’s. ha) and left it on for about 30 mins. I rinsed my hair well under cool water without taking down the twists and towel dried.

Leave-in Cond & Shea Butter Mix My leave-in conditioner and Shea Butter Mix. This will be the first time i’m using it since i made it last week.

Working a section at a time i took down the twist and applied some of the leave-in conditioner and Shea Butter mix and sectioned my hair to ‘butter’ my scalp rubbing that in well. I then cornrowed the section and moved onto the next. My leave-in conditioner is really slippery. I like it. The consistency needs to be adjusted a little to be slightly creamier and thicker in texture. Other than that i’m really pleased.

Hair-Out A section of my hair after applying the products. It’s super shrinky. Look at the difference between the length of the braided section and the loose section.

Cornrows Cornrowed hair, ready to air-dry.

 

Take Care.

My Leave-In Conditioner Recipe & Instructions

Top

I’ve finally taken the plunge and have created my own leave in Conditioner from scratch. My previous leave-in conditioner was a mix of store bought conditioner, herbal tea, oil and BTMS (a conditioning emulsifier). This time i wanted to make my own leave-in with no one else’s product in it. So i did my research on natural leave-in conditioners to see what ingredients they had in them. I put together a list of all the beneficial ingredients in all of them and used that to put together my own recipe. I found a very basic conditioner recipe online and used that as the basis of formulating my own. Once i had all the ingredients, formula and my trusty pH strips i got stuck in. I tried to take pictures at every stage but my camera died on me, which i had to quickly charge up again, so i missed out some of the steps. Sorry.

Here is my carefully put together recipe

Essential Oils –

  • Benzoin
  • Rosemary
  • Lavender
  • Geranium

Equipment

My Equipment, minus the scale and cup. I put it all in the dishwasher to clean and sterilise.

Ingredients

The Ingredients, minus the herbs.

Herbs

The Herbs

Directions

1. Start by making the herbal tea infusion. One tablespoon of each herb in a pan of boiling filtered water (about 500ml, as the herbs will absorb some). Bring back to simmering then take off heat and put a lid on. Leave to infuse till needed.

2. When ready strain out the tea through a muslin cloth or similar to remove all the bits of herb. Measure out the desired amount in a jug. Add that back into a clean pan and place that back on the heat to warm gently.

Herbal Tea Some of the tea

3. Measure out the Aloe Vera Juice into a jug

 Aloe Vera Juice

4. Add in the Honeyquat.

5. In a cup measure the Glycerine and Guar Conditioning Gum and mix together to form a paste

Glycerine & Guar

6. Add the Glycerine and Guar paste to the Aloe Juice and stir, stir, stir until it thickens well. It is suggested to stir it for 15 mins (but I didn’t, more like 3, I was going to blend it again anyway)

Aloe & Glycerine Mix Mix is all gloopy.

 

7. Measure the Lamesoft into the Aloe juice mix and stir some more

8. Measure pH of mix and if needed add in the Citric Acid*.

9. In a cup measure out the Hydrolysed Wheat Protein, Hydrolysed Silk Powder and Panthenol. Mix together and set aside.

10. In a bowl measure in your BTMS, Avocado, Coconut and Olive oils and place in the microwave or over a pan of boiling water to melt.

Oil Phase

11. Add the hot tea to the blender along with the Aloe mix and turn on. The mixture will thicken rapidly.

12. Whilst on, add in the Protein and Panthenol mix and keep blending

13. Once fully melted, drizzle the oil phase into the blender and keep blending until fully emulsified (be quick or it will set in the bowl, if this happens then re-melt). Switch off the blender and allow to cool slightly.

14. In a cup measure out the Vitamin E, Essential Oils and MicroKill, stir together

15. Turn on the blender again and add your finishing phase. Keep blending until fully incorporated.

 Blender

16. Whilst still warm and easy to pour, transfer the conditioner into your container of choice. Leave the lid off until mix has cooled to room temperature.

Pouring

17. FINISHED

Finished 

 

* I measured the pH of the mix and it was at 4 so I didn’t add in the citric acid.

It filled one 500ml bottle and there was a little left over.

Notes:

  • The conditioner ended up being really thick, so i added another 100g of Aloe Juice into the blender.
  • The consistency was a bit gummy
  • Next time i will reduce the amount of Guar conditioning gum from 1% to 0.5%. Hopefully this will solve the thickness and consistency issue.

The final pH of the conditioner was an acidic 4.5. NICE…

 

Where To Buy

I bought the BTMS, Lamesoft, Guar Conditioning Gum, Silk Protein, Hydrolysed Wheat Protein, Panthenol, Honeyquat, Citric Acid, Vitamin E and MicroKill from Of A Simple Nature

The Avocado Oil and Aloe Vera Juice are from Naturally Thinking

The herbs are from Luminescents and Woodland Herbs

 

Breakdown of Key Ingredients

Here is a list of the key ingredients in my recipe, the descriptions and how to use them.

BTMS (Behentrimonium Methosulphate (and) Cetearyl Alcohol)

Quaternary ammonium compound (Behentrimonium) blended with a fatty alcohol. Derived from Colza (rapeseed) oil. Contains 25% active quaternary conditioning agents.

A highly effective yet mild cationic self-emulsifying wax. Has outstanding conditioning properties. Substantive to skin and hair. Provides excellent wet hair comb-through and detangling. Confers reduced irritation potential. Leaves a soft, powdery after-feel. Thickening agent and stabilizer. Ideal for all skin types, including sensitive skin.

How To Use – 1-10%

BTMS is oil-soluble and should be added to the oil phase whilst it is being heated. Ensure that it is completely melted prior to combining both water and oil phases.

Recommend 3-5% plus 3% oils for a light lotion and 5-8% for a thicker cream formulation.

Lamesoft (Coco-Glucoside (and) Glyceryl Oleate)

Lamesoft is 100% plant-derived (Coco Glucoside from Coconut and the fatty acid Glyceryl Oleate from Sunflower Oil) and is gentle enough for use in baby care products.

Lamesoft is a mild, water-soluble emollient used to thicken liquid surfactant products such as shampoos, body washes and bubble baths.. It can also be incorporated into lotions, creams and conditioners.

It is also a lipid layer enhancer and thus replenishes the skins’ moisture barrier function.

It helps the hair retain its natural oils and moisture and assists with detangling.

How To Use – 0.5-5%

Add to the water phase and stir until dissolved. To achieve optimum thickness the pH should be adjusted to around 5

Guar Conditioning Gum – (Guar Hydroxypropyltrimonium Chloride)

Guar conditioning gum is a water-soluble cationic powder derived from guar gum. It is substantive to the hair and has softening and conditioning benefits, without leaving build-up. It forms a protective barrier on the hair and helps control flyaway and frizzy hair. It also promotes shine to the hair.

It adds viscosity and stability to products such as gels and serums.

How To Use – 0.5-1%

Add to water at room temperature and stir well to agitate the water. Mix until dispersed. Adjust pH to 7.0 with citric acid, if required. Continue mixing for 15 minutes until full viscosity is reached. Guar may also be mixed with glycerine prior to incorporating into the water phase or into a water-based product.

Citric Acid

Citric acid is commonly used to make fizzing bath products such as bath bombs. Use in the ratio of 3 parts sodium bicarbonate to 1 part citric acid.

It can also be used to adjust product pH and for de-scaling.

How To Use

Add to water phase to adjust the pH as needed

Silk Amino Acid Powder

Produced by the hydrolysis of pure silk fibres. Silk amino acid powder contains 100% fibroin, which consists of eighteen amino acids and trace elements.

Silk amino acids are of low molecular weight, allowing them to penetrate deep into the skin and hair shaft. They have excellent water-binding properties and thus maintain moisture levels in the skin and hair. Silk amino acids help retain elasticity in the hair and impart a soft and smooth feel to the skin and hair.

Silk powder is water-soluble and is compatible with most ingredients, including surfactants. It can be used in lotions & creams, hair conditioners, surfactant-based products, toners, gels and dry formulations such as masks, scrubs and bath powders.

How To Use – 0.05 – 0.2% (0.2% recommended)

Add to the water phase and allow to dissolve completely prior to combining the oil and water phases. When using silk powder in cold-mix formulations, add to the water and allow to dissolve completely, mixing constantly, then add the other ingredients.

Panthenol

Panthenol (Pro-vitamin B5) penetrates deep into the skin and hair shaft and has excellent water-binding abilities. It creates a protective film, thus aiding moisture retention. It helps strengthen the hair shaft by imparting an elastic film inside and out. This also helps thicken the hair and leaves the hair (and skin) feeling soft and silky.

Panthenol 75% solution is water-based. It can be used in lotions & creams, hair conditioners, surfactant-based products, gels, toners and other water-based products.

How To Use – 5% (in hair care products and 2-3% in other)

When using Panthenol in lotions and creams, add to the water phase just before combining the water and oil phases – this retains its efficacy.

Hydrolysed Wheat Protein – 0.5-5%

Hydrolysed Wheat is a pure fraction obtained from natural wheat gluten. It consists of two oligosaccharides, gliadin and glutenin, both of which act synergistically to improve the condition of the skin and hair.

Gliadin exhibits excellent film forming properties and can absorb up to twice its weight of water. It is thus ideal for retaining water levels and thus moisturising the skin and hair.

Glutenin is highly elastic and helps strengthens the skin and hair.

When used in skin care products, the addition of Wheat Protein helps improve skin tone and moisturisation. With the addition of Wheat protein in hair care products, porosity of the hair is reduced, the hair feels smoother and softer and shine and lustre are improved.

How To Use

Add to the water phase just before combining the water and oil

MicroKill (Phenoxyethanol (and) Caprylyl Glycol (and) Chlorphenesin)

Broad spectrum Parabens-free and Formaldehyde-free preservation system. Active against Gram postive and Gram negative bacteria, yeasts and moulds.

– Phenoxyethanol is a widely used, versatile preservative

– Caprylyl Glycol provides synergy and has moisturising and wetting capabilities

- Chlorphenesin is a known broad spectrum preservative

Microkill COS is effective in difficult to preserve formulations, such as water/silicon emulsions. It is compatible in a wide range of skin, hair and suncare products. It has a well-documented safety profile. Stable in a wide pH range (3-8). Water insoluble. Can be integrated into the pre- or post-emulsion stage, at or below 60C.

How To Use – 0.75 – 1.5%

It is added to either the oil phase, just before both water and oil phases are combined, or preferably during the cool-down phase at or below 60C.

In cold-mix water-based products, blend Microkill COS with an equal amount of Polysorbate 20 or 80 then add the rest of ingredients.

We recommend that the optimum usage rate for Microkill COS is 1%. However, all personal care formulations will have different requirements.

Honeyquat (Hydroxypropyltrimonium Honey)

Honeyquat is a naturally derived quaternized conditioning agent made from honey, exhibiting excellent moisture binding capabilities, far more than that seen with glycerine.

It is substantive and, due to its low molecular weight, can easily penetrate the hair shaft to provide moisture to dry, dull hair. It also helps restore shine and lustre.

Honeyquat helps reduce static build-up and improves wet combing.

How To Use – 1-5%

Add to the water phase
