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.

    My husband stole my serum!

    I’m loving this serum! My hair has been thinning for some time and I’ve loved the progress made with this product. My husband has now stolen it from me so now we’re both on this journey!

    Don’t hesitate!

    Buy Vegamour!!! I tell everyone — it really works!!! Lots of new hair growth and it does not weigh down your hair and it does not dry out your scalp. I first started seeing new growth after my second bottle, so don’t give up hope — use it daily and you will see the difference after your second bottle!!!
