"It looked so good when I left the salon. Why does it look dull already?" I hear this a lot in my chair, and the answer is almost always in the weeks between appointments, not in the colour itself. If you have been wondering how to care for colour treated hair, especially here in Kozhikode where the water, sun and humidity all work against you, this guide is the routine I give my own clients. Nothing complicated, just the habits that make the biggest difference.

Why Colour Fades Faster Than You Expect

Hair colour sits inside the hair shaft, and the outer layer (the cuticle) is what keeps it there. Every time that outer layer is roughed up — by hot water, harsh shampoo, heat tools, sun or friction — a little colour escapes. That is why two clients can walk out with the same shade and look completely different three weeks later.

A few things decide how fast your colour fades:

The First Few Days After Colouring

The first wash matters more than any other. Colour needs a little time to settle, and many colourists suggest waiting around two to three days before shampooing. Follow whatever we tell you on the day, because it depends on the product and the service.

How to Care for Colour Treated Hair at Home: The Daily Routine

This is the part that keeps your colour looking salon-fresh. None of it takes extra time once it becomes a habit.

1

Switch to a colour-safe, sulphate-free shampoo

Strong cleansing agents strip colour along with oil. A sulphate-free shampoo made for coloured hair is gentler. Shampoo your scalp, and let the lather run through the lengths rather than scrubbing them.

2

Wash less, and with cooler water

Hot water opens up the cuticle and lets colour out. Use lukewarm water to wash and finish with a cooler rinse. If you can stretch the gap between washes by a day, your colour will thank you.

3

Condition every single wash

Conditioner smooths the cuticle back down. Use it from mid-lengths to ends every time, and add a deeper mask once a week, especially on lightened or highlighted hair.

4

Protect before heat

Use a heat protectant before every dryer, straightener or curler, and keep the temperature on the lower side. High heat is one of the quickest ways to turn a rich shade dull or brassy.

5

Be gentle when hair is wet

Pat dry with a soft towel or old cotton T-shirt instead of rubbing. Detangle with a wide-tooth comb, starting from the ends. Coloured hair is more fragile when wet.

The Kerala Factors: Water, Sun, Humidity and Pools

Most colour-care advice online is written for a different climate. Here is what actually changes for us in Kerala.

Hard water and borewell water

Many homes in and around Kozhikode use well or borewell water, and some of it is hard, which means it carries minerals. Over time those minerals can build up on the hair, making colour look flat, dull or slightly brassy, and making hair feel rough even after conditioning.

Sun

Strong sun fades colour and dries out the lengths, and in Kerala we get plenty of it for most of the year. If you are outdoors for long stretches — travel, a beach day, an outdoor wedding function — cover your hair with a scarf, dupatta or hat, and use a leave-in product that says it offers UV protection.

Humidity and the monsoon

Humidity itself does not strip colour, but it makes the cuticle swell and frizz, and frizzy hair reflects less light, so the colour looks duller. A light leave-in conditioner or serum on the lengths keeps things smooth. During the monsoon, try not to leave hair tied up damp for hours after getting caught in the rain. Dry it properly, roots first.

Chlorinated pools

Pool water can dull colour, and lightened or highlighted hair can sometimes pick up a greenish tinge. Before you swim, wet your hair with plain water and apply a little conditioner so it absorbs less pool water. Wear a cap if you swim often, and rinse and condition as soon as you are out.

Coconut oil and coloured hair: I am not going to tell you to stop oiling. Many of us grew up with it and a little oil on the lengths can make coloured hair feel softer. Two cautions: skip heavy oiling for the first week after colour, and remember that thick oil needs stronger or repeated shampooing to wash out — and that extra washing is what fades colour. A small amount on the mid-lengths and ends, left for a short time, is usually enough. Before a colour appointment, ask us when booking whether to come with oiled or freshly washed hair, because it depends on the service.

Keeping Tone Fresh: Purple Shampoo, Gloss and Toner

Colour does not only fade — it shifts. Brown and highlighted hair often turns warmer or brassier over time, and pinks and reds soften towards a washed-out shade.

Book a gloss or toner when you notice the shade has changed from what you walked out with, or before a big event when you want the colour at its best. How often you need one depends on your shade and your routine, so we will suggest a timing once we see how your colour behaves.

When to Book Olaplex or a Repair Treatment

If your hair has been lightened, highlighted, coloured many times, or also has a smoothening or keratin history, it may need more than conditioner. Signs I look for:

Olaplex is a bond-building treatment we use in the salon, often alongside colour or lightening, to help protect and strengthen the hair. A hair spa or repair treatment between colour appointments also helps keep lengths in better condition. If breakage is already happening, read my guide on hair breakage after smoothening — much of the aftercare is the same for over-processed coloured hair.

Mistakes I See Most Often

Scalp itching, burning or redness after colouring is not something to put up with. Rinse well and speak to a dermatologist, and tell us before your next appointment. This is also why we patch test before every colour service, even for regular clients, and why you should patch test any new hair product at home.

Frequently Asked Questions

Many colourists suggest waiting around two to three days before the first shampoo so the colour can settle. Follow the specific advice your stylist gives you, as it depends on the product and service.
Yes, lightly. Skip heavy oiling for the first week, and keep it to a small amount on the mid-lengths and ends. Heavy oil needs repeated shampooing to wash out, and that extra washing is what fades colour.
Hard water can leave mineral build-up on the hair that makes colour look dull, flat or brassy. A shower filter, a filtered final rinse, or an occasional anti-mineral shampoo can help, but clarifying products also lift colour, so use them sparingly.
Red, pink and burgundy shades generally fade faster than browns and natural shades. Washing less often, using cooler water, a colour-safe shampoo and protecting hair from sun and heat all help them last longer. A salon gloss can refresh the tone in between.
Purple shampoo is for blonde, highlighted or balayage hair that has turned yellow or brassy. Use it about once a week rather than every wash. It is not meant for red, pink or burgundy shades.
Yes, with some care. Avoid swimming for the first week after colouring. Before swimming, wet your hair with plain water and apply conditioner, wear a cap if you can, and rinse and condition straight afterwards.
