    I have used this product for approximately two months.and it has helped with reducing breakage and makes the hair on the top of my head look thicker. In the two I have been using this product has done what it has represented it would do during the first Two months of use.

    Hair magic potion

    I’ve been using Vegamour consistently and have seen a real difference in my hair. It has significantly reduced shedding—my brush and shower drain aren’t full of hair anymore—and I’ve noticed new growth in areas that used to look thin and shallow. My hair feels healthier, fuller, and more resilient overall. So grateful I gave it a try!

    I like the consistency but I don’t see a difference with my hair yet.

    Helped postpartum hair loss!

    I had severe postpartum hair loss, as in I lost hair all around my hairline and it appeared as if I had a receding hairline. Well, with consistent use of this hair serum I saw visibly less hair loss, new baby hairs sprouting, and overall increase in growth and length. It takes time to recover but this product is amazing! The growth speaks for itself.
