Really works but patience needed!
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

Brown dye that shades the hair only

Does not work
So not only did I use this product everyday but also for close to 3 months , and guess what it done nothing , my gray hair is exactly the same as it was when I Started using it , the only thing is did was discolour my nails and any thing it splashed on in my bathroom. Don’t waste your money

Does recover colour well but also causes hair loss!
Although this product is great for removing grey, I have noticed it is causing large hair loss. I thought it was something else going on, but I noticed each time I applied it, the next day the hair fall would be excessive. This must be caused by something in the product. It's a great shame, as it is a great product for returning your hair colour. I have read that some other people have also suffered the same hair loss with this product a d other people do not appear affected by it. I think the manufacturer needs to look into the possible causes of this in some people.

Straight away!
I was so surprised that I could see my hair colour changing from the day 1! I have shiny white hair especially around my face but after applying it, the colour changed to pinkish white. It is the 4th day today and the colour is getting deeper than before. I’m very happy with the result

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.

L’ho comprato con molte riserve, oggi sono passati 7 giorni dal primo utilizzo quotidiano e il risultato è ottimo: porto la barba abbastanza lunga modellata dal Barbiere ogni 2 settimane, da alcuni anni il mio colore naturale (castano con riflessi rossi) ha iniziato a presentare delle zone di barba bianca per l’età (ho 44 anni), in particolare 2 strisce nella zona del mento, per alcuni anni sono ricorso alla tintura presso il mio Barbiere che riusciva a coprire il bianco con una tinta chimica ottenendo un risultato abbastanza naturale ma richiedeva una applicazione ogni 2 settimane. Dopo 1 settimana dall’utilizzo di questo prodotto ho recuperato completamente il mio colore naturale di alcuni anni fa! Il risultato è ottimo, totalmente naturale. Il prodotto è facile da applicare e non irrita minimamente la mia pelle sensibile (alcune tinture nel passato mi avevano dato problemi alla pelle). Se il risultato si mantiene nel tempo credo che diventerò il miglior Cliente di questa Società!

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)

17 days in. Applied exactly as instructions describe. It has done absolutely nothing. I even pulled a few white hairs to see if there's any darkening at the roots - nope. Update: 6 weeks in and there is absolutely no effect at all.

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.
