I still can’t believe I paid so much for such a product. women are not like men. We feel very sad when our hair begins to fall out. I bought this product for additional treatment to my hair shed due to hormonal changes. I bought the pro version which is the most expensive. I regret. I had no effect or side effects. my money went to waste. no changes in my hair loss. no slightest improvement in my scalp. This is a placebo product. I’m sure of it now.
