Just for MenControl GX + THK Thickening Shampoo with Grey Reduction, Shampoo for Thinning Hair with Alpha Keratin, Thickens Hair Up to 20%, Works with Every Hair Texture, 4 oz

Careful. This product works better than the Control GX. What I mean as being careful is that don’t let the product stay on your skin longer than 5 minutes. It will stain your skin. I was able to reduce my grays significantly in 3 days. Compared to others that I’ve tried, where I have to let it stay for about 10 minutes. Yes, it can stain your nails, obviously. It’s the same composition of hair. Recommend buffing your nails or wear gloves prior. Not sure about thickening the hair as I don’t have thin hair. I didn’t get any skin reactions nor itching.

I picked this up to help tone down the overwhelming gray I kept seeing in the mirror—and it’s been a smart, low-effort solution. Compared to full-on hair dye, this is way more convenient. You just shampoo your hair like normal, and after a few uses, the gray starts to soften.I typically use it twice a week, which works well—though I have noticed that the darkening effect seems to weaken a bit the longer the bottle sits on the shelf. Still, it blends the grays naturally, doesn’t make my hair look “dyed,” and takes just a few minutes in the shower. For the price and ease of use, I’m definitely happy with it.

Good product , covers up some of the gray but not all gives a more natural look than dye. Wish it would cover a little more

This product is well balanced to the point one gets to decide just how natural color to recover.

I used to dye my hair black until I went on a 6 week vacation. I used this product every day while on vacation. There was not even the slightest evidence that it was working.

Good buy

It doesn’t work and I will return it

Most of my husband’s greys are gone or hard to see.
