The next 48 hours after colouring decide how long your colour stays vibrant. A hair care routine after colouring hair is what separates colour that fades within two weeks from colour that holds its intensity across a month of washes. This guide covers every step: the first 48 hours, the weekly habits, and the products that do the real work. The routine is built around the BBlunt Hair Colour range, specifically the High Shine Conditioning Hair Colour kit, which includes a Bond Repair Serum Concentrate and a Shine Tonic Hair Mask for exactly this purpose.
Why Coloured Hair Needs a Different Routine
Oxidative hair dye works by lifting the cuticle layer, allowing hydrogen peroxide to diffuse into the cortex and develop permanent colour molecules inside the hair shaft. This leaves the cuticle temporarily raised and the cortex depleted of natural proteins and lipids, making hair more porous, more fragile, and slower to seal moisture in. A standard routine built for untreated hair is too stripping for this state. Getting the routine right from day one means your colour works with the biology of what just happened to it, rather than against it.
Step 1: The First 48 Hours After Colouring
In these first two days, avoid tying hair tightly and keep away from rain, sweat, and steam. Do not apply any oils, dry shampoos, or styling products to the scalp. Use the Shine Tonic Hair Mask that comes with the BBlunt kit within 24 hours of colouring, before your first wash. Apply to dry hair from mid-length to the ends, leave for 15 to 20 minutes, and rinse. This replenishes moisture the oxidative process removed and prepares sealed cuticles for the first wash.
Step 2: The First Wash
When you do wash, use cool or lukewarm water throughout. Hot water raises the cuticle and causes dye molecules to diffuse out. Choose a sulphate-free shampoo for colour-treated hair. Sulphates (sodium lauryl sulphate, sodium laureth sulphate) are surfactants strong enough to strip dye along with dirt, and a sulphate-free formula cleans effectively without accelerating fade.
After shampooing, apply a colour-safe conditioner from mid-lengths to ends and leave for two to three minutes before rinsing. Do not rub the hair with a towel. Squeeze out excess water and wrap in a microfibre towel or cotton T-shirt.
Step 3: Weekly Deep Conditioning
Deep conditioning is the backbone of any colour treated hair care routine. Colour processing strips the hair's natural lipid layer, leaving it prone to dryness, breakage, and dullness. A weekly mask rebuilds this layer, softens the hair, and gives colour its full reflective quality.
The Shine Tonic Hair Mask from the BBlunt kit is built for this. Apply to clean, damp hair once a week from mid-length to ends. Cover with a shower cap for 20 minutes, then rinse with cool water. For very dry or porous hair, use it on dry hair as an overnight treatment once a fortnight.
Step 4: Bond Repair Through the Wash Cycle
The BBlunt High Shine Conditioning Hair Colour formula contains MaliPeptide BondTech, combining Malic Acid and Nano-Peptides. Malic Acid re-links broken disulphide bonds in the cortex; Nano-Peptides rebuild structural integrity from inside the shaft. In clinical testing, hair treated with this system showed up to 92% less breakage compared to a marketed product (Mascot Spincontrol, Study Code XXX-RZ01-HA-AT25). After the kit is used, maintain bond health by choosing conditioners with hydrolysed keratin or silk amino acids.
Step 5: Heat Styling After Colour
You can use heat tools on colour-treated hair, but always apply a heat protectant first. Allow hair to air-dry to about 70 percent before using a blow-dryer to reduce total heat exposure. Use a medium setting. If using a flat iron or curling wand, make one pass per section rather than multiple passes over the same strand.
Finish with a small amount of silicone-based serum or shine oil on the mid-lengths and ends. This adds a protective film over the cuticle, seals in moisture, reduces friction, and gives colour-treated hair a reflective finish.
Step 6: Protecting Colour Between Washes
Limit washing to two to three times a week. Fewer washes directly extends colour life. On non-wash days, use a dry shampoo at the roots only, not through the lengths where colour sits.
Sun exposure fades colour, particularly reds and warm-toned shades. UV radiation degrades dye molecules in the outer cortex, so wear a hat during extended time outdoors or use a UV-protective leave-in spray. In pools, wet your hair with clean water first and apply a rinse-out conditioner as a barrier. Chlorine binds more aggressively to dry hair. Rinse with clean water immediately after leaving the pool.

Each shade below is part of the BBlunt High Shine Conditioning Hair Colour range. Every kit comes with the Bond Repair Serum Concentrate and Shine Tonic Hair Mask built in, so your after-colour care starts the moment you finish colouring.
Cherry Red 6.62
BBlunt Cherry Red Hair Colour 6.62A vivid, warm red with cherry-toned depth. Best suited for light brown to medium brown base hair where the red pigment shows to its full intensity. Delivers 100% grey coverage and holds its vibrancy across 32 washes. The MaliPeptide BondTech formula conditions as it colours, so hair feels soft rather than dry after processing. Ideal for anyone wanting a bold, statement red that reads as salon-done and not brassy. Use a colour-protect conditioner and limit sun exposure to preserve the cherry tone between sessions.
Chocolate Dark Brown 3
BBlunt Chocolate Dark Brown Hair Colour Shade 3A deep, cool-toned brown that gives a rich chocolatey finish across the full length. Best suited for those who want a dark, dimensional look without going fully black. Works on all base shades from natural black to medium brown, delivering complete grey coverage with a high-shine result. The ammonia-free formula keeps the scalp comfortable throughout processing. A good choice for anyone returning to a darker shade after highlights or previous colouring, as the depth is consistent and even.
Coffee Natural Brown 4.31
BBlunt Coffee Natural Brown Hair Colour 4.31A medium brown with a warm golden-beige undertone that flatters a wide range of Indian skin tones. One of the most natural-looking shades in the range because the beige undertone closely mirrors the warmth of natural Indian hair. Best suited for those wanting a gentle colour lift from black or dark brown without a dramatic change. Blends seamlessly with existing dark growth, making regrowth less visible between touch-ups. Pairs well with a weekly deep conditioning mask to keep the warm tones from turning ashy.
Honey Light Golden Brown 5.32
BBlunt Honey Light Golden Brown Hair Colour 5.32A light brown with warm golden undertones that creates a luminous, sun-kissed effect on the hair. Best suited for medium brown base hair where the golden pigment gets enough lift to show its true tone. A popular shade among those wanting a brightening effect without bleaching. The golden warmth suits warm and neutral skin undertones particularly well. Because golden pigments are sensitive to UV degradation, this shade benefits most from a UV-protective leave-in spray and cool-water rinses to maintain its brightness between colour sessions.
Mahogany Reddish Brown 4.56
BBlunt Mahogany Reddish Brown Hair Colour 4.56A medium brown with red-violet depth that adds dimension and warmth without the full boldness of a red shade. Best suited for those on natural dark brown or black hair who want a hint of red that shows in sunlight but reads as brown indoors. The violet undertone also helps neutralise brassiness on previously coloured hair. Works well for those who want a colour that looks different across lighting conditions. Like all red-toned shades, it benefits from cool-water rinses and a colour-protect shampoo to slow down the natural fading of red pigment molecules.
Natural Black 1
BBlunt Natural Black Hair Colour Shade 1A pure, neutral black with no cool or warm bias, designed to match natural Indian hair as closely as possible. The most widely used shade in the range and the go-to for complete grey coverage that looks natural rather than dyed. Suits all skin tones and all base shades. The high-shine finish makes black hair appear glossy and healthy, not flat or dull the way some permanent blacks can look. A reliable choice for regular touch-ups at home, with the ammonia-free formula ensuring the scalp stays comfortable across multiple applications.
Wine Deep Burgundy 4.20
BBlunt Wine Deep Burgundy Hair Colour 4.20A dark brown base loaded with deep red-violet tones that creates a rich, wine-like finish. Best suited for those with natural dark brown or black hair who want a bold colour statement that shifts from dark brown indoors to a vivid burgundy in sunlight. One of the most popular shades for Indian hair because the dark base keeps it wearable while the red-violet tones add striking depth. Because burgundy relies on red pigment molecules that fade faster than brown, this shade benefits the most from the full after-colour routine: cool rinses, sulphate-free shampoo, weekly deep conditioning, and UV protection outdoors.

Frequently Asked Questions
When should I wash my hair after colouring for the first time?
Wait 48 to 72 hours. The cuticle needs time to close and lock the dye molecules inside the cortex. Washing too soon flushes colour out before it has fully set.
Can I use a regular shampoo on coloured hair?
Regular shampoos can strip dye along with dirt. A sulphate-free shampoo designed for colour-treated hair cleans effectively without swelling the cuticle or accelerating fade. Check for sodium lauryl sulphate and sodium laureth sulphate in the ingredient list.
Does hot water cause coloured hair to fade?
Yes. Hot water raises the cuticle and lets dye molecules escape. Rinse with cool water, especially in the first two weeks, to keep colour sealed in.
Should I use a deep conditioning mask after hair colouring?
Yes. Colour processing depletes lipids and proteins from the hair shaft. A weekly deep conditioning mask restores moisture, softness, and reduces breakage risk.
How soon after colouring can I blow-dry my hair?
You can blow-dry right away. Always use a heat protectant first, keep the dryer on a medium setting, and let hair air-dry partially before starting. High heat on already-processed hair increases breakage risk.
Can I swim in a pool with freshly coloured hair?
Avoid pool water for at least two weeks. Chlorine breaks down dye molecules and can cause colour shift, especially in reds and warm tones. If unavoidable, wet hair with fresh water first, apply a leave-in conditioner as a barrier, and rinse immediately after.
What is the best oil for coloured hair in India?
Lightweight oils work best. Argan oil and sweet almond oil add shine without dulling the colour. Coconut oil can be too heavy for fine coloured hair and may coat the cuticle in a way that flattens the finish. Apply any oil only to the mid-lengths and ends, never the scalp.
How often should I condition colour-treated hair?
Use a rinse-out conditioner every time you shampoo, and a deep conditioning mask once a week. Under-conditioning leads to dryness, tangles, and faster colour fade.
Does protein treatment help coloured hair last longer?
A protein treatment fills micro-damage in the cortex, helping retain colour between washes. Do not overuse: protein overload causes stiffness and brittleness. Once every four to six weeks is enough.
Can I apply a hair serum on freshly coloured hair?
Yes. A silicone-based serum on damp hair forms a protective film over the cuticle, adds shine, and seals in moisture. Apply to mid-lengths and ends only.
