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.

Magic
A few years ago I noticed my hairline was slightly moving. I am in my 30s and have always had thin fine hair, which made it feel even more necessary to find a solution. Within 2 weeks I thought I noticed new growth along my hairline and overall . After a month of using this product I went for a haircut and when my hairstylist was inspecting my hair before the cut she asked why I had so much new growth on my scalp. This product genuinely works!

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!

Grew back my hairline
I have been using this consistently for years and it has drastically improved my hairline all along my forehead. I use it liberally and really rub it in nightly. My husband has even started using it. 10/10
