This is expensive. I get the good reviews. I have patchy alopecia areata which I am told is auto immune related. The shampoo/conditioner/serum pitta combo may have helped, or my hair could have been growing back by itself as part of the alopecia autoimmune cycle, I don’t know. I do know I’m grateful to have it growing back albeit it has taken 12 1 months to not show a patch of scalp. How do people afford this? I feel like I’m stuck in a cycle of not daring to stop. It needs more product than the instructions say to make it lather, I normally need to wash it three times for it to feel clean so I get through product quickly. Conditioner is good on my long fine hair, it does make a brush go straight through, which, with hair loss is really welcomed.
