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! 🙂

Wonderful

This product is amazing. My 79 year old mom has been using it every day and it has helped a lot with her hair. Her hair has been growing and it’s thick. She suffered of hair loss but not anymore thanks to this amazing product. I highly recommend using this product.

Dupe for Colorwow and smells amazing!

This smells amazing! I'm super sensitive to smell and can get migraines. This does not bother me at all. Not only does it thicken the appearance of the hair, it also acts as a heat protectant! This is considered a dupe to the color wow Dreamcoat and I'm very impressed.
