Shampoo bar for colored hair: How to preserve the color longer

Sulfates aggressively open the hair cuticle and strip away color pigments with every wash. A sulfate-free shampoo bar cleanses gently, helping color last longer and hair retain its shine between salon visits.

Color-treated hair is delicate. Every wash carries a potential risk of fading, and your choice of shampoo plays a key role in how long your color stays vibrant. Learn more about the complete routine in our complete guide to color-treated hair.

Why sulfates are color’s enemy

Sulfates are strong surfactants that cleanse effectively, but they also make color-treated hair fade faster. They aggressively open the hair cuticle and strip away color pigments with every wash. FOAM’s shampoo bars cleanse with a gentle, sulfate-free coconut-derived surfactant that cleans without opening the hair cuticle as much. The result: color lasts longer and hair retains its shine between salon visits. Learn more about sulfate-free shampoo.

Moisture is the key to vibrant color

Dry hair reflects light unevenly, making color look dull and lifeless, even if the pigments are technically still there. Well-hydrated hair reflects light evenly, making color look deeper and more vibrant. FOAM’s Forest Treat shampoo bar, with organic coconut oil and blueberry oil, is the most moisturizing option and is especially suited to chemically treated hair that needs nourishment.

The Editor’s Note: Wash color-treated hair with cooler water than you’re used to. Hot water opens the hair cuticle and speeds up color fading. A cool final rinse closes the cuticle and immediately adds more shine and depth of color.

Frequency: less is more

Every wash fades color a little. But you can minimize how often you wash by letting your scalp find its natural oil balance with a gentler shampoo. Many people with color-treated hair who switch to a shampoo bar find they can go longer between washes.

Pair it with a conditioner bar

FOAM’s DREAMY hair conditioner bar is a powerful complement for color-treated hair. Its deep-conditioning treatment strengthens the hair shaft and helps keep the cuticle closed, reducing color fading and leaving hair feeling silky smooth. Read about conditioner bars for color-treated hair and use once a week or as needed, especially after sun exposure, swimming, or intensive styling.

Color-treated hair deserves a product that cares for it as much as it cleanses. The shampoo bar does both.
