    Love!!

    I can’t say enough wonderful things about the vegamour hair serum and the entire vegamour hair care line. This truly has made a massive difference in my hair especially after giving birth. This has helped my hair feel fuller and thicker and the amount of new hair growth is crazy! Highly recommend! Gifted by vegamour.

    Works!!

    I’m glad they have this serum in bigger bottle. First of all it lasts longer but also creates less waste. I wish they made it earlier :) the serum helped me with my postpartum hair loss and I see more density. Gifted by vegamour

    love love love

    I’ve been using this product once a day, usually in the morning, and I’ve already noticed a visible improvement in my hair and scalp. I picked it because I was looking for something clean, lightweight, and effective—and it definitely delivered. The water-based formula feels refreshing and non-greasy, which is a huge plus for my routine. My hair looks fuller and healthier, especially around the hairline. Gifted by vegamour

    Amazing

    I’ve been using the Vegamour GRO Hair Serum in the jumbo size for several months now, and I’ve noticed a significant improvement in my hair’s thickness and overall health. The serum is lightweight, non-greasy, and absorbs quickly into the scalp, making it easy to incorporate into my daily routine. After consistent use, I’ve experienced reduced shedding and new hair growth, particularly around my temples. While results can vary for everyone, I appreciate that the product uses plant-based ingredients like mung bean and red clover to support hair health. The larger size is also more cost-effective for long-term use. Overall, I’m pleased with the results and would recommend it to others looking to improve hair density. Gifted by vegamour
