## Overview

This advanced anti-gray hair serum from BOOS LABS uses a unique enzymatic formula to gradually restore your natural hair color by reducing hydrogen peroxide buildup in follicles. Unlike traditional dyes, it offers a subtle, natural transition with precision root coverage, suitable for all hair types. Developed and tested in European labs, it ensures premium quality and safety, delivering fuller, thicker-looking hair with consistent use over 7-10 days and maintenance thereafter.

## 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 becomes a more transparent color (gray, silver, or white) as it grows. This advanced anti grey hair serum stops this process. It removes accumulated oxygen from oxidized colorless melanin with a unique enzymatic formula, helping reduce appearance of gray hair.WHY CHOOSE THIS SERUM OVER A DYE? Unlike a standard mens hair serum or temporary dyes, this transparent liquid absorbs quickly. It ensures a gradual transition for gray hair, delivering an ideal gray coverage touch up for your gray roots. The result is natural, thicker and fuller-looking hair without the obvious, sudden color change of chemical dyes.WHAT TO EXPECT Not an instant hair dye Results vary between individuals Best results on partially gray hair Consistent application required Visible changes may take several weeksHOW TO USE Apply a maximum of two drops to each gray spot on your scalp. Rub thoroughly into your hair with your fingertips down to the roots for proper root cover. After application, blow dry your hair thoroughly to activate the formula. We recommend applying the product once a day for the first 7–10 days. Once satisfied with the results, limit the application to 2–3 times per week to maintain your look.

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!
