W+G collaborator Dory Zayas has tried 20 growth stimulating shampoos on her thinning hair and loves this shampoo from Foligain. She says: “During my testing, I noticed that this is not a super effervescent shampoo, rather, it is a rich lather. “Since it doesn’t lather, I have to use more shampoo than usual. However, despite having 2% Trioxidil, which has been clinically proven to slow hair loss, it doesn’t have a harsh chemical smell. Additionally, there are no parabens, sulfates or phthalates. Since the instructions are to rub shampoo into your head for a few minutes to stimulate hair growth, you’re essentially forced to take care of yourself, which I appreciate.
