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.

    Real Results on curly/coily 3c/4a hair

    I started adding this to my routine and everyone else commented on my hair growth prior to me noticing the results. This product is easy to use and doesn't leave any residue. I use it while my hair is dry and a few drops go a long way.

    Having gone through chemo for colon cancer my hair started to thin in the last few treatments. I used the serum throughout ( along with your shampoo) and still use it today. My hair is thick and healthy

    My hair is growing back

    I didn't totally believe it when I first bought the set of Vegamour shampoo/conditioner/serum that my hair would grow back. I noticed the new growth on my 3rd purchase and since then I have been using only these products. I have purchased the serum more often because the bottles are small and I run out faster than the shampoo and conditioner. Also, I used to shed a lot, especially in the shower but that stopped almost right away. I am looking at my 1" long new growth and hope it grows fast.
