If you plan to lighten your hair with an at-home highlight kit again in the future, don’t skip the toning step. Learning how to tone down highlights before they turn brassy is key. A toner can cut out those brassy tones before they even appear and helps blend newly lightened areas for natural-looking highlights.
My highlights are too ashy to blend with the rest of my hair.
On the opposite end of the spectrum from brassy tones, sometimes highlights can feel too cool-toned, silvery, or ashy compared to the rest of your hair. In this case, you’ll want to add warm tones to your highlighted areas. For lighter blonde highlights, Color Therapy in Dorato can add golden honey tones. If you’re a brunette, Color Therapy in Castagna is an easy way to add subtle chestnut tones to your highlights and counteract color that’s too ashy.
When applying a color depositing mask to correct ashy tones, focus the product only on your highlighted areas. There’s no need to apply it to the rest of your hair, and in fact, spreading it all over may bring out unwanted undertones.
How to fix too dark highlights?
Highlight? Not so much…this dark color looks more like a lowlight. If your highlights are too dark, the toner you used may have darkened them past your desired color. Don’t panic—just reach for clarifying shampoo to help fade some of the darkness from the toner. These shampoos are meant to strip product (and in this case, color) out of your hair, and they can be drying. So, be sure to use a moisturizing conditioner after clarifying to prevent frizz or dullness in your bleached hair.
You can also try a primer, like our Prime for Perfection, which removes excess buildup that causes color to look dull or too dark. Prime for Perfection penetrates the hair cuticle, then it dissolves previous artificial color build-up.
If you suspect that your highlights are too dark because the color didn’t process long enough, you may need to try bleaching again. BUT—and yes, this is a big BUT—don’t let that bleach anywhere near your hair until you’ve consulted with a color pro. Bleaching again too soon could damage your hair, or choosing the wrong shade could give you a color that’s even further from your desired result.
