Superior Mane Black Soap for Grey Hair (60g) - Reverse Shampoo for Men - Shampoo Stick for Darkening Hair - Gray Shark

Not at all it doesn't work

Un regalo para mi esposo. Le encantó. Dice que siente el cabello más denso, más fuerte y ha hecho que su color natural se vea más intenso, pero natural. No parece que el pelo tiene algún tinte. Lleva como dos meses usándolo. Todavía el cabello blanco que tiene(que nunca ha sido mucho) ha obscurecido. Se ha como matizado hasta ahora

This company makes good products, this isn't one of them. Does absolutely nothing. Been using for over 6 weeks with absolutely no sign of grey going away.

Works really well for me. 51yo, golden blonde hair, some white on the sides, I leave in for 2 mins in the shower. Nice and subtle. Looks great. The Just for Men shampoos, made my hair look too dark and unnatural. Slow and steady with this bar has worked great for me.

This soap didn’t work. I have washed my hair everyday since receiving the bar. No color change.
