Let's Talk Ph.....
I thought tonight I would teach you all about Ph levels and what they mean to you in terms of your hair care products. Let's start of by finding out what exactly "Ph and Ph levels" means
Ph is a logarithmic scale that is used to measure a solutions alkalinity or acidity. Water has a Ph of 7 which means that it is neutral (pure water that is) anything above 7 is alkaline and anything below 7 is acidic, the further from 7 the more acidic or alkaline (eg....a Ph of 10 is more alkaline than a Ph or 8) What is meant by logarithmic you ask? Well you asked the right person :) logarithmic means that each number multiplies itself by 10...so a Ph or 7 is 10x(times) more alkaline. I hope that it is somewhat clear.....okay I know what you are thinking..."what does this have to do with hair and my hair care products?" Well let me tell you....

The hair itself has no Ph value but the protective mantle of the hair has a Ph of 4.5-5.5, when this is the case hair is at "its greatest strength, lustre and flexibility" (
www.veticalsinhair.com)
Now that we know the protective mantle of the hair has a Ph of 4.5-5.5 we can begin to see where I'm going with this. If the protective mantle of the hair has a Ph of 4.5-5.5 then the products that we use on our hair should have the same Ph!
So if the product has a Ph above 5.5 will act as an alkali, it will soften swell, and change the interior of the hair.
If the product has a Ph below 4.5 then it will act as an alkali, it will harden and constrict the hair.

FYI- The term alkaline refers to the ammonium hydroxide or sodium hydroxide (lye) present in a product. Its purpose is to raise the pH of a product so the chemical reaction will process rapidly. Because of its alkalinity it tends to strip the hair and scalp from its natural oils, this could be drying or even irritating to your hair and skin. Alkali is found in soaps, most shampoos, and in general household cleaners. (copyright

Just a note sometimes some products may have a higher or lower Ph because of the products intended use...some moisturizing products may have a bit of a higher Ph (e.g. 6 ) because the goal is to soften the texture of the hair. But after you colour your hair the hair is rinsed with a product that has a lower Ph. These products (that are not Ph balanced for the hair meaning not between Ph levels 4.5-5.5) are not meant to be used over a long period of time, you want to use them sparingly as you always want to return the hair to it's proper Ph level... 4.5-5.5.

So know you know what Ph level your products should have 4.5-5.5 (have I got those numbers in your head yet? :) just making sure) the next thing you need to do is find out your products Ph levels. The Ph levels are not writen on the bottle most times....so finding out is going to involve you actually calling or e-mailing the company. The companies will reply quickly (at least they have in my case) via e-mail. If you keep your hair's protective mantle at a Ph of 4.5-5.5 you will have wonderful soft, strong and shiny hair! (although that does not take the place of regular haircuts and having chemical procedures done correctly)
Good luck with your hair and as always any questions just e-mail me....there is a small button under the post, but just in case it's

Have a great hair day always!
