## Overview

For Grey Hair for Men is a cutting-edge enzymatic hair treatment that gradually restores your original hair color by neutralizing hydrogen peroxide buildup in follicles. Unlike traditional dyes, this transparent liquid supports your hair’s natural pigment renewal, delivering permanent, root-to-tip coverage with a natural, fuller look. Clinically developed and EU-manufactured, it offers a safe, easy-to-use solution for men seeking to reverse gray hair without harsh chemicals, with visible results in just one week.

## 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: Doesn’t smell and works over night - It works your natural color comes back
Review: Works on Red Hair - I've been using this Boos product since before they rebranded as FGH and called it Reparex. This silver acetate product works better than the dangerous lead acetate products (which turned my hair yellowish). This product brought back my natural color of light red, reminiscent of the color I had as a teenager, not in my 40s. I suspect that the color would be darker red if I had fuller hair, but my thinning hair is definitely red or strawberry blond depending on the light, and deeper red when wet. There is no longer any white or grey. See the photo. It works from the roots on out, which is where the instructions tell you to apply it, so the shorter your hair the faster the results (mine is long). The solution does color the rest of your hair very slightly until washed out, but what grows out influenced by the solution keeps its color permanently.

### ⭐⭐⭐⭐⭐ Best Product for All Men
*by D***D on December 4, 2021*

So easy and fast to use. I’m over 65 and just once a week maintains full color as if I were 35 years old. If you don’t use this, just enjoy your grey hair. One bottle last several months. Nothing out there is better!
