John frieda cool brunette gloss before and after

Hair Gloss for Dark Brown or Black Hair This coppery red shade adds vibrant tones to give redheads and brunettes the deep, rich color of fine Italian wine.

This is because dye pretty much just stains your hair, while gloss helps with shine and can help even, darken, or brighten your existing color.

"You do not have to color your hair to use a gloss. If you use a clear gloss, it will not color your hair. It will only add shine and benefit the overall health of your hair."

From the John Frieda® experts, this gloss hair treatment refreshes tones of color-treated hair between salon or at-home coloring, regardless of brand used. Patented technology replenishes lost tones so color looks fresh and vibrant like the first day. A refreshing boost for your blonde hair care regimen.
