Fast FAQs

Will this shade work if my natural hair is dark brown or black?

Shade 8.1 is formulated for hair that is naturally light blonde, dark blonde, or light brown. If applied directly onto dark brown or black hair without prior lightening, it will lift only slightly and may not achieve a visible ash blonde tone.

How does the ash tone eliminate brassiness?

The 8.1 shade contains cool blue-violet neutralizing undertones. During the color process, these pigments balance out the underlying warm pigments exposed during lifting, creating a clean, cool ash finish rather than an overly warm or golden look.
