I bought a bottle of this product from an ebay seller from China. It is supposed to help with new hair growth and stop hair loss. From what I have gathered, it has citrus extract and some other vitamins. Nothing special.
You are supposed to add a few drops to your shampoo, rub all into your hair and scalp and then wash it out.
It smells pleasant and I did feel like it made my hair look fuller, but later realized all it was doing was drying my scalp and hair out.
My boyfriend however likes it. He says he feels it makes his hair look fuller and hasn't felt that it has dried out his scalp. I stopped using it, but he continues to enjoy it.
