    Wow

    This serum helped increase the hair density along my hairline! I used to have this huge bald spot that I had gotten due to vitamin deficiencies. This serum made it grow back much thicker. It also does not feel greasy at ALL. Gifted by vegamour!

    baby hair growing

    I’ve been using GRO Hair Serum for a few months, and it’s amazing! My hair feels thicker and healthier, with less shedding. It’s lightweight, non-greasy, and easy to apply. My scalp feels nourished, and I’ve noticed new growth around thinning areas. Highly recommend for anyone looking to improve hair density! gifted by vegamore

    Love it!!

    I love this product!! After using for just a few weeks I have noticed my hair appears fuller, softer,a nd shinier with new growth around my hairline. I’m excited to see how much more my hair will grow and while this product was gifted by vegamour I’d definitely purchase again!

    It works!

    I’ve used Vegamour products before and they’ve always worked well for my hair however since I’ve started working out more I’ve noticed breakage and had difficult growing my hair around my temples due to wearing pony tails. I started using this 1X a day for about a month and I’ve already noticed the hairs growing! There’s tons of new growth and it’s helped fill in the balding spots. My scalp health overall has improved significantly. I used to have to do a scalp detox or scrub 1X a week and now I only need to do one 1X a month. I have an oily scalp and this hasn’t caused me any issues at all! I’ve used it on dry hair and wet hair and it has never made my hair greasy. It’s easy to apply and only takes seconds. I would recommend this product if you are in the market for an easy hair growth serum. Plus the bottle is beautiful so you can leave it on the counter as a reminder to do it daily! I received this product for complimentary from vegamour however all opinions and results are my own.

    Must have

    Complimentary from vegamour. I love how this product isn’t oily and it isn’t runny due to that. It’s the perfect consistency and the clean products is what led me to try it out! I like clean products bc i have bleached and toned blonde hair so i wanna use what’s best and this is it. My scalp has been so healthy and my growth stays my hair has been falling out less! I like to use this before a hairstyle and after a wash!
