"These six ingredients are a mix of hair color 'actives,' preservatives and contaminates, and we were able to redesign our hair color from the ground up without the need or presence of any of them," Smith explains. "We've been able to remove them from our products in order to minimize the chemical profile of our formulas while maintaining salon_quality gorgeous results." Go as natural as possible. If you still prefer natural ingredients regardless of unproven safety benefits, you may want to look to a trusted brand like Aveda, which promises a mostly natural hair_color formula.
You must condition when you're done. "If you skip the conditioner step, it leaves the cuticle open and the color keeps working," says Ionato. "So don't be surprised if you end up with much darker hair than you wanted." Don't throw away the conditioner in the kit, and if you do, make sure to use a deep conditioner in the shower after you rinse out the dye.
