Great 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...

Best 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.

No 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!
