Saw instant results

I lost half my hair from iron deficiency and had to cut the rest very short to match up to new hair growth but was still very thin overall. The first time i used this on my damp hair after my normal styling products,my hair looked instantly twice as thick. Even my mom said my hair looked suddenly thicker without me even pointing it out. I def recommend this if you have fine strands and thinning hair. Ive also been using the intensive growth drops on my scalp for about 3 months. I noticed new and thicker growth than ive ever had.

Gives my hair a little oomph.

This comes out in a fine mist and does not weigh down your hair. In fact I was a bit worried thinking that maybe I would have to wash my hair more often than my usual twice a week but thankfully that was not the case. This amazing treatment uses peptide technology to increase hair diameter which in turn strengthens your hair and prevents breakage. It has a light lovely scent and I can attest that after only a few applications my hair looks more voluminous and not as weighed down as it usually does on the days in between washing. It smells divine and after frequent use it leaves your hair looking healthier and shinier. I love that this can be used on both damp or dry hair.

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...
