Gray Hair Reverse Bar，Mane Gray Reverse Bar, Shampoo Soap for Women and Men (2 PCS)

I've read many negative reviews on this. This product isn't like hair dye, it doesn't work immediately. Using it daily my graying has slowed and REVERSED noticibly. Give it a full month, wash daily and you'll start to see the change.

Didn’t notice one ounce of a difference. I have used it for just over three weeks and it did nothing. Don’t waste your money.

Used a month religiously, not even a slight change in color. My skin reacted to something I'm thinking was in the soap and caused a rash. Had to shave my beard 😡

It is very convenient to pack in a bag and take it with you and not have to worry about spilling anything. It lost longer than a bottle of shampoo. It leaves my hair a lot cleaner and it don't wight down my hair and leve it flat.

After 2 months, I see some benefit but not total hair color change. My hair does look better and smoother per my stylist

I had gone white very suddenly over the span of 2 weeks. Ordered this and used it for over 2 months. It does nothing that they advertise it for. The claims of changing hair color is complete and utter lies. They add a bunch of ingredients that sound fancy and medicinal but it's all just to scam people and claim what they know it will never deliver on. Of course they have you money so what do they care if it doesn't work.As far as what this product is actually good for. It does a decent job cleaning you hair and doesn't leave any residue or oily film that shampoo and conditioners do. Hair stays soft and manageable with out the feeling like there's junk in it like shampoos so. Plus it's compact like a bar of soap, and you don't have to deal with a bulky plastic bottle, so it's easy to take on the go. At the price i bought it for it was about $5 a bar, and seems like each bar will last about as long as a bottle of regular shampoo. So it's decent replacement, even if all it's other claims are complete BS.

I am 77 years old with medium dark brown hair. I didn’t start going grey until I hit on my 70 now. I am seeing much more grey hair than I have wanted to say so rather than dye my hair I look for a soap and I found this a lot of natural ingredients. I’ve just start using it and I’ve been getting compliments since the first sample. Not sure if it’s really covered much grey at this point, but it’s fabulous shampoo all natural and it makes your hair feel fabulous so if nothing else I will keep using it only because of the quality of the shampoo but we will see maybe it will cover more grey it’s only the second day, but I still want to give it five stars or maybe I’ll give it for this one

Be patient. It works, but even like with skincare it is not immediately. You have to use it for at least 6 weeks or longer to see the results.
