14 Ash Brown Hair Color Ideas and Formulas

Not just for blondes; ash brown hair color is the cool hue of the moment. Taking over our Instagram feeds one post at a time, this popular shade is adding a touch of silver to brunettes with mink-toned highlights, smoked-out ombre and ashy balayage. A fresh take on classic brown hair, this stunning color is about to become your mane-stay. Whether you’re a colorist looking to perfect your technique, or simply searching for your latest hair inspiration for the new season, we’ve got everything you need to know right here.

What is Ash Brown Hair Color?

Think a cool, smoky shade with a rich, deep brunette base. Unlike warm brunettes, featuring hints of red or gold, ash brown hair is much cooler, toning things down with an almost silvery finish.

Who is it Best For?

Ash brown hair is versatile enough to be adapted to different skin tones and shades, adding elements of the look to build up the desired finish. Paired with cool skin tones, which typically feature pinkish undertones, ash brown hair color works to balance and neutralize pink or red areas of the skin. But that doesn’t mean this shade will drain warm complexions. To build up this new hue on warm skin tones, start with a classic brunette base and smoke out your shade with an ash brown balayage or ash brown ombre for a more subtle take on the trend.
