@SarahTheBeloved Saw Palmetto is know to increase hair. I bought it and pour the caps into the shampoo. About 5 to a regular size bottle. (It is from my mother's side to have thin hair.) I was looking at some old pictures of our family and realized that my hair was VERY thick at that point. I thought back and tried to figure out what I did different at that time and we were eating a LOT of brown rice. So, I tried it for a few weeks and, guess what, it worked.
