This is the first time I have ever seen these darkenyl and grey verse ingredients. I had never even heard of them until this product. Reading up on the clinical research provided this seems like a no brainer to try out. I’ve always preferred topicals to vitamins or supplements too so I immediately bought 3 bottles to make sure I give it enough time to see if it is as effective as it says.

The science can be a bit overwhelming for a product like this because the fact of the matter is something like this really doesn’t exist on the market. But those two formulations (darknyl and greyverse) they added to this serum will have huge benefits for anyone trying to reduce and reverse gray hair. Plus it still has biotin & caffeine for hair health and growth.
-Marin R.
I was a heyhair customer that was offered this product free of charge to use and provide my opinion on it. They sent me three bottles and I am just finishing my second bottle. I haven’t seen a single new gray hair since I started applying this, my hair has more volume and shine to it. If these types of results keep increasing by the time im done my third bottle I’ll be buying a subscription for this.

How Root Revival™ Works

Stimulation & Repigmentation

Greyverse™ begins by stimulating the MC1-R receptor, while Darkenyl™ stimulates hair follicle stem cells. Both activating melanogenesis, dramatically increasing melanin production and promoting effective hair repigmentation.

Protection & Nourishment

We've added powerful antioxidants like Green Tea Extract and Canadian Willow Herb, to further help reduce oxidative stress in the hair bulb, helping to reactivate the production of melanin and increase the quantity of pigment in the hair shaft.

Healthy Growth & Vibrant Hair

Formulated with nourishing botanical extracts and powerful peptides that help to moisturize your scalp, this leave-in serum strengthens hair to return it to its healthiest, shiniest, and most vibrant state.

Root Revival is formulated with natural botanicals that are both effective at hair growth and anti-gray hair growth. What separates Root Revival from other products on the market is our two patented ingredients that have been shown to not only prevent gray and white hair, but clinically proven to reverse your gray or white hair and return it to its natural hair color if used for our recommended amount of time.

This product is brilliant, but it’s a very patient game. But in the end it’s absolutely worth it. I was wondering my premature hair have gone darker but the rest are still white and I’ve been using your product longer than six months. Are they going to stay white or am I eventually gonna seee results? Root Revival™ Advanced Anti-Gray Hair Serum - Vegan Review
