    Hair serum that actually works

    My hair feels fuller and looks way healthier after just one month. It’s not magic overnight, but it’s definitely doing something. Plus, it smells nice and isn’t greasy at all. Just gotta be patient and consistent with it.

    Great serum

    I’m excited to continue using this product for hair growth. I haven’t been using it long enough to really notice a huge difference. I do love the ingredients in it and also love how it isn’t greasy since it’s water based. Everything Vegamour that I’ve used so far I’ve loved! Also the smell is very mild nothing too strong.

    So good!

    I love that this one lasted me much longer than the smaller ones. Definitely love the results hence went for the jumbo size. Hair is consistently showing better results but I feel like if I take a long break in between the hair start to fall out a little again. I was gifted by Vegamour of a review.
