How to keep blonde hair bright between appointments

Brassiness, dryness and dullness: why they happen to blonde hair and the simple routine that keeps your colour fresh.

Few things look as fresh as just-toned blonde. Keeping it that way takes a little care at home, because lightened hair is more porous and picks up warm tones over time.

Why blonde turns brassy

Lightening reveals the natural warm pigments in your hair. Toner neutralises them, but it gradually washes out. Sun, hard water and heat styling speed that up.

Your at-home routine

• Use a purple shampoo once a week, or as advised. Don't overdo it, or blonde can look dull.
• Wash with lukewarm rather than hot water.
• Use a weekly hydrating mask, since lightened hair loses moisture quickly.
• Always use a heat protector, and keep straighteners at a moderate temperature.
