System 4 delivers thicker, fuller hair by removing follicle-clogging sebum, fatty acids, and environmental residues while providing moisture balance and color protection.
Using for severe postpartum hair loss/severe scalp imbalance. I haven’t been using long enough to comment on the actual hair loss side (6months+ use needed). But can comment on the formula for general hair washing. Very strong peppermint smell, seems to clean scalp really well. Lathers nicely and you don’t need too much product for a wash. It’s not amazing though – my hair does not feel or look that great afterwards. There’s definitely no healthy shine or amazing softness! Hopefully it works for hair thinning because otherwise it’s a really underwhelming shampoo!
