Renpure Advanced Extra Strength Biotin & Collagen Thickening Leave In Spray 8.5 fl oz, pack of 1

Listen. I have THIN, THIN, THIN hair.Embarrassingly thin.Immediately after showering I apply this to my scalp and work it in.It causes the hairs to stand out and up more, creating the illusion and sensation of fullness.I have only been using it a few weeks so can't speak for the long-term results, but as above, immediate results are evident.My only complaint is that it's not vegan.

I like the way this product makes my hair feel and look thicker. It makes it look like I have more hair than I do.

This product really improves the texture and thickness of your hair!!

I bought this product from WalMart and have used it for two weeks now. I have fine curly hair and this product has made my hair thicker. I usually this on after shampooing and conditioning my hair, then after applying this product I add a leave-in and oil. Air dry then I flatiron it and I get sooo much more volume than if I hadn’t used it. My hair usually goes flat and limp, this product has changed the game for me. I would give this product five stars, but if you don’t add moisture to your hair this product will leave your hair really dry.

It does make my hair look fuller. But at the same time, it is helping my hair to grow. My baby hairs have really grown and I have new baby hairs growing where I Was losing my hair. PCOS Sucks!! Anyway, this stuff Rocks!!

It truly makes your hair so much fuller. Great product.

Gives my hair a thicker feeling texture

It did not thicken my hair, but made it feel dirty. I normally would offer it to a friend, but would feel bad giving it to them.
