Hair care products after coloring — shampoos, conditioners, masks.
Professional shampoos for coloured hair — formulas designed to keep colour saturated between salon visits and protect dye pigment from rapid wash-out. Sulfate levels are controlled, and the pH of 4.5–5.5 matches the natural acidic balance of the hair shaft.
Off-the-shelf supermarket shampoos rely on strong sulfates (SLS, SLES) and high-pH formulas that lift the cuticle and let dye pigment leak out with every wash. In the first week after colouring you can lose up to 25% of colour saturation. The Color Protect line uses gentler surfactants (coco-glucoside, decyl glucoside) that clean effectively without disturbing pigment.
For coloured hair, 2–3 washes per week with lukewarm (not hot) water is optimal. Hot water further opens the cuticle and accelerates colour loss. Apply shampoo only to the scalp and roots — the length gets cleansed as the lather rinses down. With this routine, up to 80% of the colour is preserved after 6 weeks, versus around 50% on a standard shampoo.
After a colour service, advise clients to skip washing for 48 hours so the cuticle can close and lock in the pigment. The first home wash uses lukewarm water and the Color Protect shampoo. Follow with an acidic-pH conditioner (palmitamidopropyltrimonium chloride, behentrimonium methosulfate) that seals the cuticle tight. Clients who follow this ritual return for their next colour with 30% less need for reflect toning.
Purple/silver (purple, blue) tone-correcting shampoos are used on blondes to neutralise yellow between services. Use once a week in place of regular shampoo; leave on for 3–5 minutes. Daily use can over-tone the hair to a near-violet cast. Dark blondes — every 10 days; platinum — weekly.
Professional shampoos come in large 1L bottles for the salon backbar, plus smaller retail packs you can resell as a take-home maintenance product. This is an additional revenue stream — a 30–40% margin on retail pricing.
