    wowwwww this works!!!!!

    Impressed by the results! My hair feels thicker, healthier, and noticeably fuller after consistent use. The serum absorbs quickly, smells great, and doesn’t leave any residue. After a few weeks, I noticed less shedding and new baby hairs. Definitely worth the investment for anyone looking to improve hair growth. Gifted by

    I received this gifted by the brand. I have been using this serum for months and I van definitely see the difference in the thickness of my hair. My roots overall feel fuller and I can see the new growth on my hair line. The condition of my hair and overall scalp is better and looks more healthy. I am really excited to see my results after 6 months. I would recommend to anyone.

    Love it

    It was my first time trying this product. The first few days when I applied it to my scalp, I felt a burning sensation, but then I got used to it. After a couple of weeks, I noticed my hair growing faster, looking thicker and stronger. I also love that it has clean, clinically-proven ingredients — that really matters to me.It was gifted by vegamour.
