MENFIRST - Gray Hair Reversal Shampoo - Gradual Darkening for Light Brown to Blonde Hair - Hypoallergenic & Chemical-Free - Gray Reducing Formula for Men - 2 Pack, 5 Oz Each

Working really well for me. I am a 57 year old man with gray to white hair that was dark brown many years ago. I wanted something to gradually darken so the darkening would be less noticeable. As instructions and web site state 2-4 weeks for visible results, that is what I was anticipating. Instead, my wife could see visible changes after two days / applications. The next day, after another application, she was concerned people would start to notice. I am now disciplining myself to use it every few days so I don't get too dark too fast.I apply the shampoo first thing after getting in the shower. Then I shave, which takes about five minutes, then I wash, which takes another three minutes, then rinse everything. So shampoo stays in hair around eight minutes. It takes a lot longer to apply the shampoo than normal shampoo. This is due to thick consistency and desire to thoroughly get it evenly applied to all hair.I will update review if something goes wrong, but right now I am super pleased. My only challenge is not getting dark too fast.Three months later: Using it every day now. Still very happy. No one who doesn't know I am using it has commented on my darker hair. Good stuff.One year update: My usage over the past year has averaged about 6 of 7 days each week. No one except the few I have told are aware I am using it. No one has noticed due to the very gradual progression. I really like the fact that it retains, to a degree, the original light and dark shades of my hair to start with. It doesn't darken all the hair the same shade. This way it does not look dyed.In December I got the conditioner to try out. It is okay. I don't really see a use for it unless you are into extra super conditioning. The one impact it had for me for the two months I used it was to add extra darkness and lengthen the time it was in my hair, this caused my hair to get darker, quicker. I checked the price per ounce and it is close to the price of the shampoo. So if you want conditioner, use it. Otherwise you could get the same effect by applying more shampoo and leaving it in longer. I have added pictures so you can see how much darker the hair has become over the year.

I've used and appreciated Menfirst Gradual Gray reducing shampoo before but this batch is different.1) The label information was in Spanish so if the directions had changed from before, I couldn't read it.2) Even after shaking, the shampoo came out of the tube in nearly the consistency of water. It ran through my fingers and what I managed to get in my hair mostly ran off. This consistency made a hell of a mess as it splattered all around the shower so I had to scrub the shower after use to prevent staining.3) Unlike the previous shampoo, this batch immediately stained my hands creating the need to scrub my hands multiple times.

Old stuff worked as described, a gradual shampoo. But this new stuff in the green bottle is like actual hair dye. Almost red. Dyes skin for about a day.

I like this product. I could've given it 5 stars.I am 74. I am white on the sides ,kind of ash on top.This product doesn't eliminate the white on the sides but it tones it down, and it darkens the top a bit so the overall effect is darker hair.I like that it is very natural looking.It leaves the highlights and doesn't give me that monotone dark hair that many hair dyes do.I took a tip from one of the other reviewers: I put it on first thing in the shower and then wash and shave in the shower. By the time I am finished with that the requisite 5 minutes has elapsed.This is my go-to shampoo now.It takes a couple weeks to really see the results.

No, I'm not going to put a ridiculous before & after picture of myself. That being said I was more grey than my 51yr old version of myself really cares to have at this stage. After a couple of uses the gradual darkening did work & I'm happy with the results. With darker hair the gradual balding spot on the crown shows up more but at least I'm not totally grey & balding. Too bad this doesn't take care of regrowth at the same time. I plan to buy another tube after my current one runs out. I did buy the gel too but not planning on buying that again.****update...I purchased a 2nd round after the first ran out. It's not the same as the first container I got. The first one had a nice scent & it didn't stain my hands. This new container is exactly the same on the outside but the shampoo stains my hands & the nice scent is not there. I'm not sure if they sent me an older container or if they ship a cheaper version after they get you hooked on it. Even the consistency of the shampoo is different. All this being said the color is still doing a good job on my hair & by the end of my shower my stained hands are pretty much back to normal. I plan to keep using it & I'll post an update when I get a 3rd container.

I like the way the brown looks however it's a disaster to use if you're in a guest's shower. I am on the road always staying in random places. Random places including other people's showers and this shampoo is a no go when staying as a guest in someone else's place, especially if they have a shower curtain and/or white towels to dry off with. I have both the black and the brown and the brown is noticeably different and more like a dye. Other customers are right. It stains your skin terribly. It splatters all over the walls of the shower and stains the shower if you don't immediately wash it away. Your hands are stained. It is way more like dye than a shampoo. No lathering or anything. I like the way it looks on my hair but it's hardly worth it considering the mess it makes.The black color is noticeably not as messy. Neither have a scent. It just seems like a product that is not fully developed and not ready for market if you ask me.
