Colour fades because the cuticle opens and dye leaks. Sulphate-heavy shampoo and hot water hurry that along. These five are the original colour-care shortlist: hydrate, lock, bond-maintain, anti-fade and a silver wash for brass.
Pureology Hydrate Shampoo
Colour-protecting hydrating wash. Moisture for dyed hair that already feels like straw.
Redken Colour Extend Magnetics Shampoo
Acidic cleanser designed to help keep dye in the fibre. Gentle daily-ish wash for coloured hair.
Olaplex No. 4 Bond Maintenance Shampoo
Repair-minded wash for bleached and highlighted hair. Colour protection plus the bond story.
Joico Color Intensity Shampoo
Daily colour-protecting shampoo for blonde, brunette and vivid tones.
L’Oréal Paris Serie Expert Silver Shampoo
Deposits cool pigment on blonde, grey and highlight. Use once or twice a week, not every wash.

Does sulphate-free shampoo protect colour?
Gentler surfactants are less likely to rough up the cuticle. That helps tone last.
How often should I wash colour-treated hair?
Two to three times a week is a good target for many heads.
Will purple shampoo damage my colour?
Used weekly it deposits cool pigment. Daily use can overtone. Alternate with a plain colour-safe wash.
