What is the lowest allowed pH level of professional hair products by law? in EU & US
Hello all,
Since I haven’t found any online reliable source for this question, I was wondering - what is the lowest allowed pH level of professional hair products (hair straightening) according to the regulations of EU and the US? taking into consideration that a “Safety Assessment” report is necessary.
Thanks in advance for your answers and have a great weekend.

The lowest level is the level which you can prove will not harm people. There isn’t a number. There is a formulation & how it affects skin.

The Cosmetic Product Saftey Report (CPSR) is issued looking at all the ingredients and how they fit into the legal restrictions.
Do you have a formulation in mind? I could have a look and see if it would be considered “safe”
