For Grey Hair for Men - Get Your Original Hair Color Back

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.

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!

Si oscurece el pelo (tambien las uñas si no utilizas guantes) con un tono rojizo rubio. Super artificial! Lo tire despues de una semana.

I bought this product for my husband as a treatment for his gray hair particularly in the temples area. After few weeks of consistent using, the gray hair started to fade away. His hair’s regained its natural tone. The application should be consistent to get the desired result. I recommend this product.

After a full bottle application my gray hair is still there. Some faded slightly on top of my head, but the sides are just as visible as before. I can't say it’s worth the effort, even if it was free, let alone having to pay for it. The only thing that darkened was the application glove. Don’t waste your money, dye is much more efficient and fast. (Pics at 2 week intervals)

Was getting fed up of using fake looking hair colour so decided to give this a try. Happy to report results are fantastic but it took considerably longer than 7-10 days to get my natural hair colour back (black). It changes hair colour gradually and it took around 3 weeks to get rid of all grey hairs - I was probably 50% grey. I was applying this straight after showering and towel drying my hair. Then spent a few mins drying my hair using a hair dryer. Am now using this 2-3 times a week to maintain the colour Pros: - Brings your natural hair colour back - Solution is a clear non-greasy liquid with a very faint lemony/citrus smell, almost like water - Doesn't appear to contain any nasty chemicals such as Ammonia or Hydrogen Peroxide - Very easy to apply - Unlike regular hair colour, removes grey from hair roots as well Cons: - Expensive! - Results are slow, especially if you have lots of grey hairs. Stubborn grey hairs will be the last to change colour. - Leaves nasty stains on your fingernails if you don't use gloves when applying solution

Had it on for a couple of months and it turned into a reddish brown not even close to being black also leaving a smell I can't describe? I wouldn't recommend
