Shampoo bar for colored hair: How to preserve your color longer
Sulfates aggressively open the cuticle and strip away color pigments with every wash. A sulfate-free shampoo bar cleanses gently so your color lasts longer and your hair retains its shine between salon visits.
Color-treated hair is delicate hair. Every wash carries a potential risk of color fading, and your choice of shampoo plays a crucial 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 the enemy of color
Sulfates are strong surfactants that cleanse effectively, but they are also what fades color-treated hair fastest. They aggressively open the cuticle and strip away color pigments with every wash. FOAM’s shampoo bars cleanse with a gentle, sulfate-free coconut-derived surfactant that cleanses without opening the cuticle as forcefully. The result: your color lasts longer and your 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 the color look dull and lifeless even when the pigments are technically still in place. Well-hydrated hair reflects light evenly and makes the 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 suitable for chemically treated hair that needs nourishment.
The Editor’s Note: Wash color-treated hair with cooler water than you are used to. Hot water opens the cuticle and accelerates color fading. A cool final rinse closes the cuticle and immediately gives your hair more shine and color depth.
Frequency: less is more
Every wash fades the color a little. But you can minimize the number of washes by allowing your scalp to find its natural sebum balance with a milder shampoo. Many people with color-treated hair who switch to a shampoo bar find that they can extend the time between washes.
Complete your routine with a conditioner bar
FOAM’s DREAMY hair conditioner bar is a powerful complement for color-treated hair. The deep moisturizing treatment strengthens the hair shaft’s structure and helps keep the cuticle closed, reducing color fading and leaving the 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.
