How soon can I expect to see results?

When applied daily, expect to see results from GRO+ Advanced Hair Serum in 3-4 months. Our best advice: Consistency is key. Using daily is essential to seeing a visible improvement.

Will it make my hair greasy?

No! The formula is lightweight, fast-absorbing and water-based. It can be applied to wet or dry hair without disturbing your style. In a 120-day consumer perception study of individuals using GRO+ Advanced Hair Serum daily, 98% of participants agreed the product did not make their scalp feel greasy.

What is the difference between GRO+ Advanced Hair Serum and GRO Hair Serum?

GRO Hair Serum is a great option for those who are looking for a proactive approach to hair wellness or are starting to see early signs of shedding. Those with moderate to severe shedding or scalp concerns are best suited to use GRO+ Advanced Hair Serum, our most advanced formula yet.

Does this contain CBD?

Unlike the prior formula, the new GRO+ Advanced Hair Serum does not contain CBD. Instead, GRO+ Advanced Hair Serum features Spanish Microalgae, a prebiotic superfood that hydrates to balance the scalp and support a healthy skin barrier.

Can men use this product?

Yes! We had male and female participants in our clinical studies, and found the formula to be effective for both.

Worth every penny!
I have been using Vegamour for about 3 years now. When I wanted to save some money I cut out my subscription and stopped using this product. I had NO idea how much it was helping my hair! After about 3-6 months of not using the product anymore I couldn’t stand it and I started my monthly subscription back up. When I use this product I have less breakage, my hair is shinier and stronger over all and my favorite part is I notice new hair growing constantly at my top hairline which is why I purchased the product in the first place!

This stuff works!
Love it! By my mid 20's my hair started to slowly become thinner and thinner. I tried Rogain, I tried hair vitamins- nothing worked. By my mid 30s, I wasn't able to tie a hair tie around my pony tail without it slipping off shortly after, so I resorted in getting hair extensions. After having my 2nd son, I decided to start building healthy hair. My stylist recommended this product to me and said she has seen it work on her other clients, so I thought why not? This product literally took 2 weeks to show results! My hair line became fuller and eventually I began to see less and less of my scalp and more hair! I am now able to tie my hair back without feeling conscious, and the hair tie stays on!
