feels good and definitely thickens your hair

I have used this spray several times in the past and I'm always very pleased. I also use the shampoo and conditioner by the same maker. I'm pushing 60 and my hair is getting very thin, but with this regimen I am definitely seeing a difference! Thanks a bunch! 🙂
