My hair stylist uses a sulfite free color/dye to protect my scalp....it helps👍🏻

Because the warning on the box says not to use on damaged scalp I'm gonna say it can. Results may vary.

I’ve always colored my hair and my scalp always seemed better afterwards. IDK

Chemicals in commercials dyes can be a catalyst. I used natural henna. Comes in all colors and is just ground up plants.

No I’ve had mine since I was born.
