    Worth!

    . After using Vegamour’s GRO Hair Serum for several months, I can confidently say it’s been a game-changer for my hair. Initially, I was skeptical about yet another hair growth product, but the results have exceeded my expectations. Within the first month, I noticed a significant reduction in hair shedding. By the third month, baby hairs began sprouting along my hairline, and my overall hair density improved noticeably. The serum’s lightweight, non-greasy formula made it easy to incorporate into my daily routine without leaving any residue or weighing down my hair. Even on days I didn’t wash my hair, applying the serum didn’t make it look oily, which is a huge plus for someone with fine hair like mine. Consistency is key with this product. In summary, Vegamour’s GRO Hair Serum has revitalized my hair, making it thicker, healthier, and more resilient. It’s an investment, but for me, the results have been well worth it.

    Effective after 2 months of use

    Gifted by vegamour. I like Vegamour's GRO Hair serum from the design, ingredients to the effectiveness of the product. After giving birth, my hair fell out a lot, every time I washed my hair I couldn't count the number of hairs that fell out. I have been using GRO Hair serum every day, continuously for more than 2 months (of course there are days when I forget) and you can see: The number of baby hairs is growing a lot: it's like a fluffy brush. It makes my hair look thicker, my scalp is also healthier and the amount of hair loss is significantly reduced. The serum has a liquid texture, you just need to squeeze the tube gently to get the drops of serum inside, warm it with your 2 palms and massage the scalp (the visible areas) every day. It is light and absorbs very quickly and does not cause stickiness to the scalp.

    Hair Improvement

    Vegamour gummies & serum have helped my hair for sure. It hasn’t been huge but slowly changing. Slightly thicker. Still working on the length but I know hair change takes time.

    Helpful tool with hair loss

    I started losing my hair once I entered perimenopause. I tried some hair growth products with chemicals in it and it made me really sick. I was so grateful when I found the Vegamour Gro serum because it didn't have chemicals in it and it actually worked. I tried the Gro plus serum as well but have had better results with the Gro serum. Consistent use is key but it does work!
