Kerotin Extensive Thickening Treatment Spray for Fine and Thin Hair - Spray I Hair Diameter Booster and Heat Protectant. All-natural, Cruelty and Alcohol-Free, Made in the USA. (1)

I’ve been using this for probably over a year and it’s fantastic! My hair is full and honestly recommend for continuous use!

This Keratin thickening spray is awesome!! Makes my hair really look thicker!!

I'm half way through my first bottle..I have very fine and thin hair and this product seems to be making it a little thicker and it's protecting my hair from heat damage..not as dry looking

Hasn’t worked yet, but too soon to tell.

It doesn’t make your hair gooey! It gives shine and fullness!

My third reorder! I love this product! It is light and penetrates easily. I highly recommend for thining hair.

Great product to increase hair volume. When I use it people comment on the fullness of my hair. No stickiness, gumminess or fullness. Im on my 2nd bottle and it goes a long way

I’ve been using this product for a long time. I failed to write a review. I absolutely love this. In just one use you can feel the fullness in your hair. It really does work. Doesn’t make your hair feel greasy or unmanageable. I give this product a 5 star!
