## Overview

For Grey Hair is an innovative, enzyme-based hair care solution designed to gradually restore your natural hair color by targeting the root cause of graying. Unlike traditional dyes, it supports catalase activity to remove oxidative buildup, works on all hair colors including roots, and delivers visible results within a week. Manufactured in the EU under stringent quality controls, this transparent liquid formula offers a mess-free, science-driven alternative to hair dye, lasting over a month per bottle.

## Description

HOW IT WORKS Hair goes gray due to the accumulation of hydrogen peroxide in hair follicles, causing oxidation of melanin. A hair follicle that no longer contains as much melanin, will become a more transparent color (gray, silver or white) as it grows. For Grey hair stops this process, removes accumulated oxygen from oxidized colorless melanin with the enzyme glucuronate reductase, which binds with silver nitrate and prevents further oxidation HOW TO USE FOR GREY HAIR - Apply a maximum of two drops to each spot on your scalp - Rub thoroughly into your hair with your fingertips - After application blow dry your hair - We recommend applying the product once a day for the first 7-10 days. - If you are satisfied with the result, you can limit the application to 2-3 times per week

Review: Works great! Used it for years. - I've used this product for years (it was originally called Reparex), and it works great...IF you follow the directions. It's not a dye (you use the same bottle no matter if you're a brunette, redhead, etc.), but it just reverses gray hair temporarily back to your normal color. So if you like your normal, natural color, then this is for you. Your gray hair WILL grow out again (just like it does if you dye your hair), so you do have to keep applying to your roots as needed. After applying, I'd recommend blow drying it and not putting your head anywhere you don't want it to stain (couch, pillow) until the product fully dries. I usually sleep on a dark pillowcase just to be safe, but I've never had a problem. Wait two or three days if possible to wash your hair to allow the product to fully set and penetrate your hair follicles. I notice my hair starting to change colors within 24 hours, but it takes two or three days for it to fully return to the natural color. And, yes, you can wash your hair as normal with normal shampoos. It is a little runny and messy because it has a watery consistency (maybe something a little thicker would create less waste and mess?), but I now use a hair dye bowl and brush to apply it and that has helped tremendously. I'd recommend applying it in old clothes that you don't mind staining and immediately wiping down the floors and countertops as soon as you're done because the product WILL stain after a couple of hours otherwise. But it's not a huge deal at all. This product has been a godsend because I love my natural color and didn't want to dye my hair. It does take a bit of work but no more than dyeing your hair at home. Love it and highly recommend! Wish the price was $20 cheaper like Reparex was.
Review: Really wanted this to work but it’s not - Maybe I did something wrong but I followed the instructions exactly and it unevenly has started to change colors. But instead of dark brown it is turning orange and some areas of beard no change at all.

### ⭐⭐⭐⭐⭐ Ive been using them for years now
*by D***K on May 22, 2025*

I grew my hair out (gray) and decided I didnt like it, but didnt want to dye it again.. I really did get sick of sitting in a chair every 3-4 weeks. So Ive been using this for going on 2 years now. I do love how turns out, it's far more natural than box dye. It does require maintenance that takes about 2 minutes at first every day until you get the results you want and then you can pair it down to a few times a week. Do it after a shower with clean hair as the longer it stays on the better.
