Nice serum, seems to be working, though I know you have to use it for a while. I didn't love the spray nozzle though, made it a bit hard to get it on my scalp through my thick hair

I had purchased these for my father as he has lot of gray hair and he seems to like this product! The progress of reversal is gradual, but if you stick to use of this product, we have noticed the graying process seem to slow down. The product smells pretty nice too. Had to deduct a star because the price is really really steep considering the product size is not too big.

This spray makes my hair feel nice and the grey hairs do not stick up as much as before. However, it is too soon to tell if it is making a change in the color of my roots.

I had bought this for my dad and after about two months of continual use on his head, you can tell that his hair is growing darker naturally! It definitely takes time so you need to stick to this product for quite a while, which can be difficult given the steep price of this product, but worth a try!

Ok I have used it nearly daily for 4 months. Pre I was around 30% gray and now maybe 10%. Easy to spray on with a light, pleasant scent and one bottle lasts a little over a month. I am decreasing my salon visits to every 8 weeks so it's a win.

This product sounded too good to be true and it is. Nevertheless, I decided to give it a try. Bought three month supply since that was the timespan referenced in the clinical tests. For reference, I'm in my early 40's and have some gray hair around temples and around hair line. Used it for 3 months. Zero changes to my gray hair.

I only start using this product for 2 weeks. I have high hope for it. It's not greasy on your scalp and have light pleasant scent. I will give it time to find out the results. The reason I gave 3 stars is because it's too early to say if it work or not.
