## Customer Reviews

### ⭐⭐⭐⭐⭐ Impressive results right from the first try!”
*by E***Z on July 17, 2025*

Review:I loved this shampoo. It’s very easy to apply, doesn’t stain like other dyes, and leaves my hair super soft with a deep, shiny black color. It also smells great and doesn’t irritate the scalp. I used it without gloves and it didn’t stain my hands. I’ll definitely buy it again!

### ⭐⭐⭐⭐⭐ Leave on longer
*by P***B on July 1, 2025*

It covers gray hair beautifully, I leave it longer than instructions because first time it wasn’t quite effective so now I leave on roots 30-40 minutes and it looks natural, not harsh on hair at all.Too bad it only works once so you have to use it all up which is impossible and mechanism breaks it exploded in my cabinet and now only pumps the clearer part which doesn’t work alone. The product is good but mechanism is bad.Seller reached out to try and correct and sent me another one. Excellent customer service. I stopped using hair dye for roots ever since I found this. I love the product. Hope pump works.

### ⭐⭐⭐⭐⭐ Stumbled across this and it's good
*by J***T on June 25, 2025*

I have to color my beard to keep ahead of the gray and I like how fast and effectively this product works. I also touch up my regular hair with this too. My beard grows so fast that this really makes it easy to keep it looking good daily.I apply mine directly with a hair color brush, wait about 7 minutes and then wash off the excess.Recent photo reveals the results...
