How to Repair Bleached Hair: A Step-by-Step Recovery Routine

Bleaching is the most demanding thing you can do to your hair. Lightening removes natural pigment from inside the strand, and in the process it weakens the hair's structure and roughens its surface. Bleached hair often feels dry, stretchy, tangly and frizzy — but with the right care it can look and feel healthy again.

Quick answer: To repair bleached hair, switch to gentle, moisturising cleansing, condition every wash, use a strengthening mask at least weekly, protect with a leave-in serum, avoid heat as much as possible, detangle only when conditioned, trim damaged ends and space out future lightening appointments.

What Bleach Does to Hair

Bleach opens the cuticle and breaks down the melanin pigment inside the hair. That leaves the strand more porous — it absorbs water quickly and loses it just as fast — and weaker, so it's more likely to stretch and snap. The lighter you go, the more the hair is affected.

Signs Bleached Hair Needs Repair

  • Dry, rough, straw-like texture
  • Hair that feels gummy or stretches when wet
  • Lots of tangles and knots
  • Frizz and flyaways
  • Split ends and short broken pieces
  • Yellow or brassy tones as toner fades

If hair feels gummy or is breaking in large amounts, see a professional stylist before doing anything else.

How to Repair Bleached Hair: Step by Step

1. Cleanse gently and less often

Use lukewarm water and a gentle, moisturising shampoo. For thick or coarse bleached hair, 700 Keratin & Kale Shampoo helps smooth and strengthen; for finer hair, 911 Quinoa Shampoo restores moisture and shine.

2. Condition every single wash

Bleached hair tangles easily. Apply plenty of conditioner, such as 700 Keratin & Kale Conditioner, and detangle gently while it's in.

3. Use a strengthening mask weekly

The 700 Keratin & Kale Hair Mask is an intensive mask with keratin, pro-vitamin B5, vitamin E and castor oil for highly damaged, coloured or chemically treated hair. Use it once or twice a week in place of conditioner.

4. Tone to keep blonde bright

Alternate your repair mask with the 19 Pro Silver Hair Mask, which neutralises yellow and brassy tones while deeply hydrating. See How to Maintain Blonde and Silver Hair.

5. Seal with a leave-in

Apply a serum to damp lengths. 700 Keratin & Kale Hair Serum smooths frizz and split ends and protects from heat and UV; 19 Pro Silver Serum adds anti-yellow toning for light shades.

6. Keep heat to a minimum

Air-dry where possible and keep hot tools on low. Bleached hair is especially vulnerable to heat damage. Read How to Repair Heat-Damaged Hair.

7. Handle with care

Blot instead of rubbing, use a wide-tooth comb, avoid tight elastics and sleep on a satin pillowcase.

8. Trim regularly

Trimming removes the most fragile ends so breakage doesn't travel up the strand.

9. Space out lightening

Give hair time between bleach services and ask your stylist to lighten only new regrowth rather than overlapping on already-lightened lengths.

Weekly Routine for Bleached Hair

  • Wash days: gentle shampoo → conditioner → serum.
  • Once a week: 700 Keratin & Kale Hair Mask.
  • Once a week: 19 Pro Silver Shampoo or Mask for tone.
  • Daily: low heat, gentle handling.

Common Mistakes

  • Bleaching again before hair has recovered
  • Brushing wet bleached hair roughly
  • Using high heat without protection
  • Using toning shampoo every wash, which can dry hair and dull tone
  • Skipping masks

Frequently Asked Questions

Can bleached hair go back to normal?

The bleached lengths won't return to their original structure, but good care can make them softer, stronger-feeling and shinier while healthy hair grows in.

How often should I mask bleached hair?

At least once a week; very damaged hair may benefit from twice a week.

Is keratin good for bleached hair?

Keratin-enriched products help smooth and strengthen the hair surface, making them a good choice for bleached hair.

Why is my bleached hair so tangly?

Bleach roughens the cuticle, so strands catch on each other. Regular conditioning, masks and serum make detangling easier.
