Hair Color Cream Schwarzkopf 12-21 Medium Ash Blonde

Schwarzkopf Hair Color Cream 12-21 Medium Ash Blonde is a permanent oxidative cream hair dye formulated to deliver a medium ash blonde shade. Designed for both full-head coloring and targeted root touch-ups, this product requires mixing with an appropriate developer to activate the oxidative dye system. The cream base helps with even pigment distribution and smoother application, while the ash tone reduces warm undertones for a neutral to cool blonde result depending on the starting hair level.

Advantages

The cream formula ensures consistent coverage and easy blending, reducing streaks and uneven patches. As a permanent oxidative dye, it provides long-lasting color and gray coverage when used according to instructions. The ash pigments in shade 12-21 help neutralize brassiness and create a cooler blonde appearance. The product is suitable for professional salon use as well as controlled at-home applications when paired with the correct developer and following safety guidelines.

How to use

Perform a patch test 48 hours before application according to safety instructions.

Usage recommendations

To achieve the intended medium ash blonde result, assess the starting hair level and condition. Very dark or highly pigmented hair may require pre-lightening. Use the appropriate developer strength to control lift and tone, and consider a follow-up toning or conditioning treatment to refine coolness and maintain hair health.
