    It works

    I always trust this brand in helping grow my hair, because their products work! I had lost a really big chunk of my hair around my forehead, and after applying this serum, I noticed my hair growing back in about 7 to 10 days of continue use. You can definitely use it all over or just on patches that need help "gifted by vegamour

    Patience & Consistency

    I been looking for someone to help revive my fine textured hair and give me some thickness and/or growth. It’s still new to me but I’ve been consistent and it definitely gives me the idea of some fullness is occurring. It’ll honestly take 2-3 bottles plus consistency to see a huge difference but I’m invested.

    Thickening that works!

    Being postpartum my hair was thinning out and falling out to the point that I had balding spots. This made me feel uncomfortable with myself, but being able to sample this serum and to see results from it was a true blessing! Besides being super easy to apply it left no greasy residue on the hands or hair for that matter. My hair is fuller now and I feel so much better about myself. I can now style it how I would like without the embarrassment. Gifted by vegamour.

    It really works

    My hair line had been receding on both sides of my face, intensifying my widows peak. It’s been like this for a very long time, little to no growth on the sides around my face. It’s only been 3 months and the results are clear…it really works!

    I feel much more confident now about pulling my bangs back now, definitely gong to keep using this consistently and excited to see the results 6 months from now! :)
