I received a question at facebook asking about the pH of DIY recipes. If you didn’t already know, pH plays an important role in hair care products, particularly the ones we leave in our hair after washing and conditioning.
For leave-in conditioners/moisturizers, I try to make sure I formulate to ensure the pH is 4.5 – 5 (and sometimes 4). Try to stay in that pH sweet spot of 4 – 5.5. This is because lower pH conditioners (positive charge) love the negative charge of hair.
