Herb Speedy Color Cream.

If your skin is too sensitive for traditional hair dye ingredients (like PPD and ammonia), you’ll love this ultra-gentle alternative. And even though it’s gentle, it still gives you tons of color payoff and shine. Just make sure you start with a patch test if your scalp is really sensitive
