After 2 months I felt like I have more brown hair. Still saw gray but felt less. After about 4 months, my environment spoke to me about it. My personal feeling is that I got darker hair all over again. It can stay that way. A great product

Use the product for about 2 months and apply it to washed hair daily. The visible grayish strands have become less. Will keep using it now and keep you updated.


Lars Kast

am absolutely thrilled. it actually works. I'm 29 years old and unfortunately I have already discovered a few gray hairs and have been using it for about 3 months. Since I only wash my hair every 2 days, I was only now able to see the first results. Some gray hair has actually turned noticeably darker. Recommend it to everyone.
