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.

I cannot be without this product!!!
I have been using this product faithfully for over 3 years now and cannot be without it!! It has my hair growth stimulated and my hair is fuller all around!! I started out with the basic serum and when Gro+ was available I was too excited to start it. If you are thinking of trying this product, go ahead and do it!! No pills to worry about upsetting your stomach or additional shedding when you begin the serum. Thanks VEGAMOUR!

Hope Seen!
Bald edges and top of hair from stress and hormone changes. The product is filling in the hair. In less than 45 days hair follicles are being seen and the spots are filling in. Like with most, I’m a little impatient with the timing for the fullness desired. However, I feel more confidence and evidence with this product than with any other tried! Stay tuned!
