what we do best
Testing your hair porosity when no one else will.
One of the most difficult yet vital characteristics we test is your hair’s porosity, or rather its damage. Why is this test so important? Damaging our hair is all too easy to do on an almost daily basis. Perhaps you’ve been using products that aren't actually meant for your hair type, or you’re using too many products in an attempt to repair moisture or split ends which could actually damage your hair further.
Either way, one of the most important things you can learn about your hair care routine is what to change, and the best way to do that is to get to know your strands — damage and all.
