Hair Care After Highlights and Balayage

Highlights and balayage brighten hair beautifully, but the lightened sections are more delicate than the rest of your hair. Lightening opens the hair cuticle and removes pigment, so those strands lose moisture faster, tangle more easily and can turn brassy. The right aftercare keeps the colour looking salon-fresh for longer.

Quick answer: After highlights or balayage, wait 48–72 hours before the first wash (or follow your colourist's advice), wash with lukewarm water and colour-safe products, use a toning shampoo once a week to keep blonde tones cool, mask weekly, protect from heat and sun, and book a toner refresh or gloss when your colourist recommends it.

Why Lightened Hair Needs Extra Care

  • It is more porous. Lightened strands absorb and lose water quickly, so they dry out and frizz.
  • It is weaker. Lightening breaks down some of the hair's internal structure, so it snaps more easily.
  • It turns warm. Underlying yellow and orange tones show through as toner fades.
  • It reacts to the environment. Sun, chlorine, hard water and heat speed up dullness and brassiness.

The First Two Weeks

  1. Delay the first wash by 48–72 hours, or as your colourist advises.
  2. Use lukewarm water. Hot water lifts the cuticle and fades toner faster.
  3. Choose colour-safe products. The 700 Keratin & Kale Shampoo is colour-safe and made for chemically treated hair.
  4. Avoid clarifying or deep-cleansing products in the first week unless your colourist recommends them.
  5. Keep heat low. Air-dry when you can; use a heat protectant if you style.

Your Weekly Routine

Wash and condition

Wash two to three times a week with a gentle, colour-safe shampoo and always condition. For dry, dull highlights, the 911 Quinoa range restores moisture and shine; for thick or frizzy hair, use 700 Keratin & Kale.

Tone once a week

Use 19 Pro Silver Shampoo once a week to neutralise yellow and brassy tones in the lightened sections. Start with a shorter time on very light pieces. See How Often to Use Silver Shampoo.

Mask weekly

Alternate a toning mask, the 19 Pro Silver Hair Mask, with a repair mask such as the 700 Keratin & Kale Hair Mask, which is made for coloured and chemically treated hair.

Seal and protect

Apply a leave-in to damp hair. 700 Keratin & Kale Hair Serum helps smooth frizz and split ends and offers heat and UV protection. For very light, cool blondes, 19 Pro Silver Serum also helps neutralise yellow between washes.

Balayage vs Highlights: Any Difference in Care?

The care is almost the same. Balayage is painted on and usually concentrated on the mid-lengths and ends, which are already the oldest and driest part of your hair, so focus masks and serum there. Foil highlights often run closer to the root, so toning shampoo should be worked through from the roots as well.

Protecting Your Colour

  • Cover hair in strong sun.
  • Wet hair and apply conditioner before swimming, and rinse straight after.
  • Clarify only when needed if you have hard water; see Hard Water and Hair.
  • Keep hot tools on a medium setting.
  • Sleep on a smooth pillowcase to reduce friction on fragile ends.

When to Go Back to the Salon

Toners fade over a few weeks. Ask your colourist about a toner or gloss refresh between full appointments, and book a trim every 8–12 weeks to remove dry, split ends. For lasting results, read How to Keep Salon Results at Home.

Frequently Asked Questions

Why are my highlights turning yellow?

As toner fades, the natural warm tones in lightened hair show through. Sun, hard water and heat speed this up. A weekly silver shampoo helps.

How long should I wait to wash after balayage?

Many colourists suggest 48–72 hours, but follow the advice of the person who coloured your hair.

Can I use purple shampoo on balayage?

Yes, on blonde or light balayage. Apply it mainly to the lightened sections and keep the time short at first.

How do I stop my highlights from feeling like straw?

Mask weekly, use a leave-in serum, reduce heat and get regular trims. See How to Repair Bleached Hair.
