Coloured or Bleached Hair: Care Between Salon Visits

Short answer: Coloured and bleached hair needs more conditioning and less stress than uncoloured hair. Lightening opens the cuticle and leaves strands more porous, so they tangle, dry out and break more easily. Between salon visits, wash less often in lukewarm water, condition every time, use a mask weekly, keep heat low and detangle from the ends upwards.

Quick facts

• Bleach changes hair for good: lightened lengths stay more porous until they are cut off.
• Colour fades with frequent washing, hot water, heat styling and sun.
• Conditioning is non-negotiable: conditioner every wash, a mask once or twice a week.
• Wet lightened hair is at its most fragile. Detangle gently, from the ends up.
• Your colourist knows your hair's history. Ask before adding more colour or lightener at home.

What does bleach do to hair?

Bleach lightens hair by breaking down the natural pigment inside each strand, and to reach it, it has to open the cuticle. Lighteners are oxidising products. They lift the overlapping scales on the hair's surface, travel inside and break down melanin, the pigment that gives hair its natural colour. The lighter you go, the more pigment is removed and the longer the process runs.

Afterwards, the cuticle does not close back to its original state. Lightened hair is more porous: it soaks up water quickly, swells, loses it quickly and feels dry. It also becomes rougher, so strands catch on one another and tangle. When wet, heavily lightened hair can feel stretchy or gummy, which is a sign it needs very gentle handling.

How is coloured hair different from bleached hair?

The more a process lightens hair, the more care it needs afterwards.

Process	What it does	What you notice	Care focus
Gloss or toner	Adds or adjusts tone, mostly on the surface	Shine, fades over several weeks	Gentle washing to slow fading
Permanent colour, same shade or darker	Opens the cuticle to deposit colour inside	Some dryness, fading at the ends	Regular conditioning, lukewarm water
Highlights or balayage	Lightens selected strands	Lightened pieces feel drier and tangle more	Mask on lightened lengths, gentle detangling
All-over bleach or platinum	Removes most natural pigment	Porous, dry, fragile when wet, prone to yellow tones	Weekly mask, minimal heat, toning shampoo
Repeated lightening over the same lengths	Stacks the effect on older hair	Rough, gummy when wet, breakage	Very gentle handling, trims, a frank talk with your colourist

How should you care for coloured hair between salon visits?

Bleached hair care and coloured hair care follow the same rule: less washing, more conditioning and less heat.

1. Wait before the first wash. Many colourists suggest a day or two after colouring. Follow your colourist's advice.
2. Wash less often, and use lukewarm or cool water. Hot water speeds up fading.
3. Shampoo the scalp only. Let the rinse water clean the lengths.
4. Condition every time, from mid-lengths to ends.
5. Use a mask once or twice a week in place of conditioner.
6. Detangle with conditioner in, using a wide-tooth comb, starting at the ends and working up.
7. Blot with a soft towel and avoid twisting wet hair into a tight turban.
8. Keep heat low and use a heat protectant when you style.
9. Protect from sun and pool water: wear a hat in strong sun, wet your hair with tap water before swimming and rinse straight after.

Why does blonde hair turn brassy?

Because lightening exposes the warm, yellow and orange tones underneath, and the toner that neutralises them fades. Every head of hair has underlying warm pigment that shows as it is lightened. Toner covers it for a while, then washes, sun and minerals in tap water wear it away. A purple or silver shampoo, used once a week or as your colourist suggests, deposits a little cool tone to balance the warmth. Use it sparingly: too much can leave very light hair with a lilac cast.

Where does a protein-rich mask fit?

It is the weekly step that gives porous, lightened lengths more conditioning and a stronger feel. Our Keratin Intensive Rescue Hair Mask is designed for hair that feels dry, brittle or stressed by colouring, heat and styling. Hydrolysed keratin, wheat proteins and peptides help hair feel stronger and reduce the look of breakage and split ends. Shea butter and vitamin E condition the lengths, so hair feels softer, detangles more easily and looks shinier.

Use it once or twice a week, or whenever your hair needs extra care. After shampooing, apply it generously to towel-dried hair, focusing on the mid-lengths and ends, leave it for five to ten minutes and rinse thoroughly. Use it in place of your conditioner. It is not vegan, because it contains hydrolysed keratin, and it contains wheat proteins.

A note on balance: if lightened hair starts to feel stiff, rough or straw-like after several protein-rich products in a row, alternate the mask with a plain, moisturising conditioner and mention it to your colourist.

Common mistakes

• Washing every day in hot water. It is the fastest way to fade colour and dry out lightened lengths.
• Brushing wet hair from the roots down. It pulls knots into the most fragile part of the hair.
• Using irons at full heat. Lightened hair needs the low end of the dial.
• Stacking several protein products every wash. Alternate with moisture-focused conditioning.
• Colouring over salon lightening at home. Overlapping chemistry is unpredictable. Ask your colourist first.
• Skipping trims to keep length. Rough, split ends can split further up.

What care won't do

No mask can reverse lightening. Lengths that have been bleached stay more porous, and broken strands do not rejoin. Good care makes coloured hair feel softer, look shinier and break less, and it slows fading, but the real fresh start comes from the root: new hair comes through uncoloured, and regular trims gradually replace the most processed lengths. If your scalp burns, itches, swells or blisters after colouring, rinse it out, stop and see a doctor. That is also why many hair dye packs ask for an allergy alert test before each colouring.

Frequently asked questions

How often should I use a hair mask on bleached hair?

Once or twice a week suits most lightened hair. Use it in place of your conditioner and concentrate on the mid-lengths and ends, where the hair is oldest and most processed.

How soon can I wash my hair after colouring?

Many colourists suggest waiting a day or two, but follow the advice you were given at the salon or on the colour pack. When you do wash, use lukewarm water.

Why does my bleached hair feel gummy when wet?

That stretchy, gummy feel is a sign of heavily processed hair. Handle it very gently, avoid heat until it is dry, and talk to your colourist before any further lightening.

How often should I use purple shampoo?

Once a week is a common starting point, or as your colourist suggests. Leave it on briefly at first. Too much can tint very pale blonde hair with a lilac tone.

Can bleached hair go back to how it was?

The lightened lengths can't. Care makes them softer and more manageable, but the change from lightening stays in that hair until it is cut. New hair at the root comes through in its natural state.
