What is pH? Professional Hairstylist? Pink Hearts? Is it Puppy Hugs?
Actually, pH stands for “power of hydrogen.” You remember, right? From 5th grade science class?
The pH scale measures the acidity or alkalinity of a liquid where water is the base. The scale goes from 0 to 14, with 7 being the neutral middle. With that being said, 0 to 6 is considered to be acidic, while 8 to 14 is alkaline, or basic.
Believe it or not, pH levels have a lot to do with your hair health.
The average pH for your hair and skin is 4.5, which is actually acidic. Weird, huh?
Things on the more basic side expand your hair’s cuticle, such as hair color, perms and straightening treatments. The products used have to lift the cuticle to get the chemicals into the hair shaft to color the hair, or whatever you are trying to do.
That is why shampoos generally have a pH level of about 5 to 6.5. The shampoo is still acidic, but it needs to have a higher pH level to be able to clean the hair properly and remove any build-up. But be careful, you have to make sure that the shampoo is not too acidic; it can make the hair too rough and tangly, and the conditioner won’t be able to bring it back down.
And this is where the conditioner comes into play. In the salon, I hear this a lot, “Conditioner weighs down my hair so I don’t use it.” Or, “I have fine hair so I don’t use conditioner.” This actually does more harm than good. Once the shampoo does its job in lifting the cuticle to clean everything out, the conditioner, which usually has a pH level of 4.5, has the power to bring your hair back to the level that is going to keep it in its healthiest form.
Having a basic understanding of pH can assist you in maintaining your luscious locks! Find out what the pH of your products are by calling the number on the back of the bottle.
