"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.
Similar to Hair Color, the Hair Color Booth app lets you experiment with your hair colour in crazy shades. You can also select just some of your hair to try different colour streaks or ombre colour combinations. This is a great app to freak out your mum or friends too! There's only a few colours in the free version but it's enough to try some rainbow hair.
