The corresponding conditioner is then formulated to be more acidic with a pH ranging from 3.5 to 5.0.
Why does this matter for your hair?
As pH falls hair constricts and becomes less porous, i.e. your hair retains moisture much better and is shinier. This means that as you clean your hair, the lower the pH of the final product used in the process, the better your hair cuticle is sealed off.
What if you don't want to use a shampoo and conditioner in the same line?
There are a couple of simple solutions:
- Either check that the pH of your conditioner is lower by getting pH paper or
- Rinse conditioner out with cool water. Cool water also helps to flatten and close of the hair cuticle
