United StatesGreat product
My hair is thinning. I used many brands for over 8 years but nothing changed. When I started to using Kerstin products last winter, my hair started growing faster. Now I use it everyday. I recommend to friends. My hair feels thick now. Happy...

AustraliaBest Hair Products for my hair
I’ve been using Kerotin Extensive Thickening Treatment for six months. I noticed since embracing my 50s my hair was breaking and didn’t look as thick or healthy. But I’m excited to say after using this product my hair is looking a lot more healthier, less breakage and moisture. I highly recommend this product for any ladies embracing their 50s, 60s, see photos below.

Hi Heather! There is nothing more rewarding than seeing a customer with positive feedback. Thank you so much for taking the time to share your experience with the product!
United StatesNo Sticky, Heavy Feel
I absolutely love this product! It is far better than any mousse or other treatment I have tried. I spray it on after towel drying my hair and it makes a subtle difference yet does not weigh my hair down nor feel sticky. I like how clean it smells and feels. This may be hard to understand, but you don't know it's there but you know it's there because your hair feels thicker!

Hi Kellyann! That's so good to hear! We’re glad you are pleased with the result.
