Frequently Asked Questions

Like any good wellness routine, results require effort to be maintained. If you stop using GRO Hair Serum, you'll see hair return to its natural state within a few months of discontinuing use.

When applied daily, expect to see results from GRO Hair Serum in 3-4 months. Our best advice: Consistency is key. With HYDR-8 Weightless Repair Oil, you’ll see instant results after your first use.

Apply a quarter-size amount each of GRO Revitalizing Shampoo and Conditioner. Use one dropper of GRO Hair Serum daily to see results in as soon as 90 days.** A little goes a long way with HYDR-8 Weightless Repair Oil, so always start with less and add more.

    Gave me curls

    I love using the GRO hair serum, it has helped out with my thinning spots. I can actually see hair coverage, I wish I had taken before and after pictures. It also has given me curls which I love, not sure if that's hormonal or a combination of both.

    Highly recommend

    The GRO hair serum is incredible. I received this product complimentary from vegamour. After 2-3 weeks of using this daily, I noticed my hair looks healthier and feels stronger. Highly recommend this product.

    Unbelievable thickness

    This product is unbelievable. I have been using this serum for about a year and a half. After giving birth to my son, I lost so much hair. Every time I washed my hair clumps would fall out. Thankfully, I have curly hair, but you would still be able to see a lot of bald spots Amongst my head. I get so many compliments on my hair now it is so full. I tried all kinds of remedies and growth products and nothing worked. These products have been a game changer. Currently I use the serum and shampoo and conditioner.

    Great for keeping scalp moisturizer

    This was gifted by Vegamour. I’m glad I had an ample amount of time to review this product over the last three months. I noticed that my scalp is a little bit less itchy, which makes sense since the serum lubricates my scalp, but I don’t think I’ve seen any significant changes as far as hair fullness
