Do I need to bleach my hair first?

Yes, for visible mint. The pastel tone shows on pre-lightened blonde or platinum hair. On natural brown or dark hair it will barely register.

Do I mix it with a developer?

It is designed to be mixed with Goldwell Colorance Lotion, not used straight from the tube. Follow the ratio on the Colorance instructions.

As a semi-permanent color, it fades over several washes, typically a few weeks. Cool mint tones tend to wash out faster than warm shades.

Mint-green neutralizes red and warm tones, so it can cool brassy blonde. Use a light hand, since too much green leaves a visible cast.

The acidic base is gentler than permanent color, and Goldwell markets it as repairing. Bleached hair is still porous, so strand-test first.

It is a salon-line product, but experienced home colorists do use it. Mixing and timing errors are the main risk with pastel shades.
