Procam Scalp Therapy Shampoo

I was worried because my hair has been falling out a lot lately, so I bought this on a friend's recommendation and have been using it. It is said to contain three types of patented probiotics to strengthen the scalp barrier and moisturize the hair. Since it was my first time using a hair loss shampoo, I was like, "What is this?" It gave a tingling sensation, slightly like a menthol patch, so it felt just like a cooling shampoo.

I've been using it for about a week, and I hope it works.
