    I’m impressed!

    I’ve been using the Vegamour serum since mid-Nov 2024 and recently switched to the Gro+.

    I have tried rogaine and hated how it made my scalp itch and my hair look greasy. This serum is amazing - I put it on once in the morning after using product and before drying my hair and not only is there no scalp irritation, but using the serum actually made my hair look denser even before I started noticing a real difference. It’s early March now, and my hair absolutely looks and feels fuller and healthier. Highly recommend giving it a try for at least 3 months. There’s no downside!

    amazing product

    All of the vegamour products have worked so well for me. I used the regular gro serum for a few months before switching to the gro+ serum to see if it would increase my results even more. I was dealing with excess hair shedding from a new medication and my hair was feeling really thin. I am now on my second bottle of the gro+ serum and it has worked wonders for my hair. I have so many baby hairs coming in, and my part and hairline are filled back in. I have also been using the shampoo and conditioner along with the serum, and my hair feels so so healthy from this combo. I get complimented all the time on how healthy and shiny my hair looks. Definitely would recommend!

    GRO Hair Serum works!

    I’ve been a customer for years and I know this product keeps my hair thicker and prevents thinning! I took a break for about 6 months to try other products and I came back to GRO… it works!

    Love the hair serum

    I have been usually Vegamour products for about 6 months. I love the way they make my hair feel. I have been losing a lot of hair and the Gro+Advanced Serum has helped tremendously. My hair is slowing down on the amount that was coming out. I would recommend this to anyone I know.
