Making ash blonde hair can be quite tricky, as it requires a precise combination of colors to get the perfect shade. To achieve a beautiful and healthy looking ash blonde, you should mix equal parts of cool toned blondes such as platinum and light beige blonde with a small amount of warm toned medium brown. This will give your hair dimension while keeping it cool-toned. Additionally, when mixing these colors together, you should add in just enough gray to soften the color and help create an overall subtle tone that looks natural. Lastly, for extra brightness around the face or any other desired areas on the head, use highlights in shades ranging from ivory to pale gold to make sure everything blends well together without appearing too yellow or brassy tones. With patience and practice you can easily master this technique at home!
