Why Hair Colour Fades Fast in Malaysia, and How to Make It Last

Quick answer: Hair colour fades fastest when the cuticle is open and the colour molecules can wash out. Hot water, frequent washing with harsh shampoo, sun, heat styling, chlorine and porous or previously lightened hair all speed it up, and Malaysia's heat and humidity mean most people wash more often. To make colour last, salons should use the right developer and full processing time, then seal the hair afterwards. At home, wait a couple of days before the first wash, then use a colour-care shampoo and mask in lukewarm water, protect hair from sun and heat, and use a purple or blue toning product once or twice a week if colour turns brassy.

This guide is written for salon owners and stylists in Malaysia, and for clients who want their colour to stay rich for longer. The products named are ones NX Hair & Beauty Supplies stocks, with Venash Professional (which NX distributes exclusively in Malaysia) as the main example.

Why hair colour fades

Permanent colour works by opening the cuticle so the dye can develop inside the hair. Over the following weeks, some of that colour gradually escapes every time the cuticle lifts again. The main reasons:

• Washing: every wash, especially with hot water and strong shampoo, lifts the cuticle and rinses out a little colour.
• Porosity: damaged, bleached or highly porous hair can't hold colour well, so it fades faster and more unevenly.
• Sun (UV): sunlight breaks down colour molecules, especially on the top layer of hair.
• Heat styling: hot irons and dryers dull colour and dry out the cuticle.
• Chlorine and minerals: pool water, and metals and minerals in tap water, can dull or shift colour.
• The shade itself: reds, coppers and vivid fashion shades tend to fade fastest. Lightened hair tends to turn yellow or orange (brassy) as the toner washes out.

Why colour fades faster in Malaysia

• Strong sun all year round: constant UV exposure, especially for anyone who rides a motorbike, walks or works outdoors.
• Heat and humidity: sweat means most people wash daily, which means more fading.
• Hot showers and air-conditioning: hot water lifts the cuticle, and dry air-conditioned rooms dry hair out.
• Swimming: chlorine is one of the fastest ways to dull or shift colour.

For salons: making colour last from day one

1. Check the hair's condition first. Very porous or damaged lengths absorb colour fast and lose it fast. Treat them before colouring, or adjust the formula for the ends.
2. Use the right developer for the job, and process for the full time. Under-processed colour washes out quicker. Venash AF Developer is an ammonia-free developer made for Asian hair, with antioxidants that coat the hair surface to help lock in colour depth.
3. Choose the colour to match the client's lifestyle. Venash Professional hair colour (with Keratin Technology) and Venash Fashion Hair Color both mix 1:1 with developer. Warn clients that reds and vivid fashion shades need more upkeep.
4. Seal after colouring. Rinse thoroughly, then finish with a colour-care treatment rather than a basic conditioner. Venash Treatment Masque 2000ml helps protect hair fibres from oxidative damage and preserve colour shine (3–5 minutes). NX also stocks L'Oréal Professionnel Vitamino Color Acidic Sealer for after the colour service.
5. Send clients home with a plan: the right shampoo and mask, and how long to wait before the first wash.

Home care: the first few days

• Wait before the first wash. Many stylists advise waiting 2–3 days, to give the colour time to settle. Follow your stylist's advice.
• Avoid swimming and very hot showers for the first week.

Home care: long term

• Switch to a colour-care shampoo. Venash Treatment Shampoo is a colour-care, hydrating and smoothing shampoo with Ceramide A2 PHTM, formulated to enhance colour protection for colour-treated hair. Also stocked by NX: Kobo Color Locking Shampoo (2) and Schwarzkopf BC Color Freeze, a sulphate-free pH 4.5 shampoo.
• Wash in lukewarm or cool water, and wash less often if you can. On sweaty days, rinse with water and condition the ends rather than shampooing every time.
• Use a colour-care mask once or twice a week. Venash Treatment Mask is a colour-care, repairing and moisturising mask (10–15 minutes). Other options: Joico K-PAK Color Therapy and L'Oréal Vitamino Color.
• Protect from the sun. Wear a hat or cover hair in strong sun. Kobo Color Protective Mist (2) is a lightweight mist with UVA and UVB protection for coloured hair.
• Protect from heat. Keep tools at a lower temperature, and use a heat protectant first. L'Oréal Vitamino Color 10-in-1 Spray is a leave-in for coloured hair that includes heat protection.
• Before swimming, wet your hair with clean water and apply a leave-in, so it absorbs less pool water. Rinse straight after.
• If your colour shifts or dulls unexpectedly, minerals and metals in water may be a factor. NX stocks the L'Oréal Professionnel Metal DX range, designed to remove metal particles that can cause colour shift.

Fixing brassy or faded tones

When colour fades, warm undertones show through. Toning shampoos and conditioners deposit a little opposite-colour pigment to cancel them out:

Problem	Use a…	Stocked by NX
Blonde, grey or highlights turning yellow	Purple / violet shampoo or conditioner	Kobo Yellow Out Pure Violet Shampoo, Joico Color Balance Purple, L'Oréal Professionnel Silver Shampoo
Lightened brown hair turning orange	Blue shampoo or conditioner	Joico Color Balance Blue Shampoo and Conditioner
Dark brunette turning red or copper	Green colour-depositing mask	Kérastase Masque Vert Chroma Neutralisant

Use toning products once or twice a week in place of your normal shampoo or conditioner, not every wash, or the tone can go too cool or dull. If the colour has faded a lot, a salon gloss or toner refresh works better than toning at home.

Lightened hair that is also dry or breaking needs care as well as toning. See our guide to bleached and damaged hair.

Frequently asked questions

Why does my hair colour fade so fast?

Usually a mix of frequent washing, hot water, sun, heat styling and porous hair. In Malaysia's climate, daily washing because of sweat is often the biggest factor, so a colour-care shampoo and lukewarm water make a real difference.

How long should I wait to wash my hair after colouring?

Many stylists recommend waiting 2–3 days. Follow your stylist's advice for the colour they used.

Which hair colours fade the fastest?

Reds, coppers and vivid fashion shades fade fastest. Lightened blonde shades tend to turn yellow or brassy as the toner wears off.

How do I stop my hair from turning brassy?

Use a purple shampoo for yellow tones, or a blue shampoo for orange tones, once or twice a week. Protect hair from sun and chlorine, and ask your stylist for a toner refresh between colour appointments.

Does sulphate-free shampoo help colour last longer?

Gentler, colour-care shampoos generally help colour last longer than strong everyday shampoos. Look for one made for colour-treated hair, and wash in lukewarm water.
