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

This is not a miracle product. But it will make your hair darker and healthier looking. This is not permanent hair coloring. It builds up on your hair. It will not make your hair jet black but will make it darker. For best results apply on dry hair 10 minutes before showering. Use a separate conditioner to seal color in place after rinsing. Pat your hair dry and finish drying with a hair dryer. I never had any stains on my skin. I have been using it everyday for a year. P.S.: I never make reviews in exchange for free products.

Leave the Santa Claus look, or embrace going bald, but at all costs, do NOT buy this product. It comes out of the tube looking like dark jelly, with about the same consistency. The instructions say to leave it in for 5 minutes ... DON'T DO IT!In the interest of easing in very gradually, I left it in for 30 seconds ... and the skin under by beard now LOOKS GREENISH-BLACK, so even if the beard didn't darken appropriately, shaving it off is not an option. I washed my face for a really long time with shampoo, and the skin staining got lighter, but it is not gone. Thank god I can work from home for a few days, if needed.Not only does my face have a dark section underneath the beard, the dye doesn't work very well on the beard itself — maybe 10 percent of which looks a little darker.The rest of the tube went rightt in the trash — a lot of money spent to dye my face ... which was not the goal.This stuff is expensive and absolutely horrible.

Used for a while now. Tried manufacture's tips for how to get success on hard to effect grey templehair. On second bottle now and hardly any effect at all. Works well on the rest of my hair though.

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.

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 will preface this review by saying that before I even purchased this I read to achieve quicker results it was recommended to apply to dry hair, leave on for 15 minutes before rinsing out, which is what I did.I initially thought this was working pretty well as I used it daily for about 3 weeks. It appeared my hair was getting darker without overdoing it. The issue started for me that it seemed like my hair was far less manageable than normal and drier than normal. One day I decided use my normal daily shampoo before using Menfirst (Tricomin Densifying Shampoo and Tricomin Reinforcing conditioner that I get from a doctor's office). I used the Tricomin one time and all of the darkness that had been achieved with Menfirst was completely gone and my hair was very very gray. I cannot continue using Menfirst as I am really bothered with how it leaves my hair and especially seeing that using a normal shampoo one time completely removes any progress you have made makes this product imo worthless and a sham.I would not recommend this product unless you are looking for something that only lasts until you wash your hair one time with normal shampoo. I will never use it again and feel stupid as after the first week I purchased a second bottle which I have since thrown in the trash.I guess it will work for those that don't have their hair really dried out like it did for me. It says it is also a conditioner but it clearly didn't seem that it had any conditioner in it at all for me. My hair also appeared less dense as well when using Menfirst.Disappointed is an understatement.
