Ash in hair color refers to a cool, grayish-blue undertone added to hair dye, primarily used to neutralize unwanted warmth and brassiness, especially in blondes and light brunettes. It's often used as a toner to cool down the roots or specific sections of the hair.
Understanding Ash Tones
-
Cooling Effect: Ash tones counteract warm tones like yellow, orange, and red. This is why they are popular for achieving a cooler, more neutral blonde or brunette shade.
-
Additive, Not Primary Color: Ash is usually added to a hair color formula rather than being the primary color itself. This allows stylists to customize the amount of ash to achieve the desired effect.
-
Toner Application: Ash toners are frequently used to maintain or adjust the tone of pre-lightened or colored hair. They deposit subtle pigments that neutralize brassiness.
Why Use Ash Tones?
-
Neutralize Brassiness: One of the main reasons people use ash tones is to combat brassy or orange undertones that can appear in lightened or colored hair over time.
-
Create a Modern Look: Ashy shades are often associated with a modern and sophisticated aesthetic.
-
Enhance Natural Hair Color: Ash tones can also be used to enhance natural hair colors by adding depth and dimension.
Considerations
-
Overall Matte Finish: While ashy tones are desirable for neutralizing warmth, too much ash can result in a dull, matte finish that lacks dimension. This is why stylists often apply ash strategically, focusing on areas prone to brassiness.
-
Skin Tone: Ashy hair colors can sometimes make fair skin appear washed out, so it's important to consider skin tone when choosing an ash shade. Consulting with a professional stylist is highly recommended.
-
Maintenance: Ashy hair colors may require regular toning to maintain the cool tone and prevent brassiness from returning.
In summary, ash in hair color is a cool-toned additive used to neutralize warmth and create a more neutral or cool-toned shade, often applied as a toner, but careful application is key to avoid a dull, overly matte finish.
