You’ve dyed your hair and regret it. Whether the shade is wrong, it’s brassy, or you’ve simply changed your mind, you’re desperate to get the colour out. Fortunately, multiple methods exist, ranging from gentle home treatments to professional interventions. Understanding which method suits your situation prevents further damage and gets you closer to your desired hair colour.
Quick Answer Box
How do I remove hair colour? For semi-permanent dyes, frequent clarifying shampoos fade them over 6-10 washes. For permanent colour, colour-removing products (£12-30) strip dyes from the cortex, or professional stripping services (£50-150) provide faster results. Going lighter than your current colour requires bleaching. Each method has different damage levels and effectiveness.
Understanding Your Colour Type and Removal Options
Semi-Permanent Colour
Semi-permanent dyes (like Directions, Manic Panic, or drugstore semi-permanent options costing £4-10) don’t contain ammonia and don’t permanently alter hair structure. They coat the hair surface and penetrate minimally. These fade naturally over 6-10 shampoos.
Removal method: Wait and wash. Use hot water and harsh shampoo to accelerate fading. Wash daily in hot water, use clarifying shampoo (Malibu Hard Water Shampoo, available from Boots for £8-12), and colour will fade noticeably within 2-3 weeks.
Demi-Permanent Colour
Demi-permanent dyes contain minimal ammonia and gradually fade over 12-24 shampoos. These sit between semi and permanent in permanence.
Removal method: Accelerated fading or colour-removing products. Clarifying shampoo works but slowly. Colour-removing products (like Wella Color Charm Colour Remover, roughly £15 from Boots) work faster, removing demi-permanent colour in 1-2 applications.
Permanent Colour
Permanent dyes contain ammonia and open the hair cuticle, depositing colour molecules into the cortex. Once there, they don’t wash out. Removal requires breaking those colour bonds or completely bleaching them out.
Removal methods: Colour remover products, professional stripping, or bleaching. Each carries different risks and costs.
Method 1: Clarifying Shampoo (Safest, Slowest)
This method works best on semi-permanent colours and light permanent colours.
How It Works
Clarifying shampoos contain higher detergent levels than regular shampoos, stripping product buildup and, to a lesser extent, some colour molecules. Over multiple washings, colour gradually fades.
Process
- Wash your hair daily with clarifying shampoo for 2 weeks
- Follow immediately with deep conditioning (essential—clarifying is harsh)
- Avoid heat styling during this period
- Expect 30-50% colour reduction by week 2
Cost and Timeline
- Cost: £8-15 for clarifying shampoo
- Timeline: 2-4 weeks for noticeable results
- Best for: Semi-permanent colours, light permanent colours, people with sensitive scalp
One reader shares: “I used clarifying shampoo daily for 3 weeks after a dark semi-permanent dye disaster. The colour faded from nearly black to medium brown. It was slow but my hair stayed healthy, and I didn’t have to spend £100 at a salon.”
Method 2: Vitamin C Flushing (Natural, Mildly Effective)
High-dose vitamin C can slightly reduce permanent colour. It’s gentler than chemical removers but also less effective.
Process
- Crush 1-2 grams of vitamin C tablets (roughly 10-20 tablets, cost £2-4)
- Mix with a small amount of shampoo and water to form a paste
- Apply to damp hair, focusing on coloured sections
- Cover with a shower cap and leave for 30 minutes to 1 hour
- Rinse thoroughly with warm water
- Repeat 2-3 times weekly for 4 weeks
Effectiveness and Timeline
- Cost: £2-4 for vitamin C tablets
- Timeline: 4+ weeks for 10-20% colour reduction
- Best for: Light colour reduction, people avoiding chemicals
Vitamin C flushing is genuinely gentle and costs almost nothing. However, it’s ineffective for permanent dark colours. If you dyed your hair dark and need significant colour removal, skip this method.
Method 3: Colour-Removing Products (Moderate Effectiveness)
These products are designed to strip colour from hair without bleaching.
How They Work
Colour removers contain thio-based chemicals that break down colour molecules. They’re less harsh than bleach but more effective than fading methods. They work best on light to medium colours.
Application
- Section dry hair into 4-6 manageable parts
- Follow product instructions for mixing (most require mixing two solutions)
- Apply section by section, ensuring full coverage
- Process for 10-30 minutes depending on product
- Rinse thoroughly with cool water
- Deep condition intensively (these products are drying)
Effectiveness and Cost
- Cost: £12-30 per application
- Timeline: 1-3 applications for noticeable results
- Best for: Permanent colour, wanting to avoid bleaching, light to medium colours
Important: Colour removers are less effective on dark colours. On black or very dark brown, they might barely lighten. On light brown to medium blonde, they work quite well.
Method 4: Bleach Washing (Fast, Damaging)
This combines low-volume developer with bleach powder to gently lighten colour. It’s less damaging than full bleaching but more so than colour removers.
Process
- Mix bleach powder with 10 or 20 volume developer (20 volume is standard, available from beauty suppliers or Amazon)
- Apply to hair like shampoo, working quickly
- Process for 10-20 minutes (monitor closely—check every 5 minutes)
- Rinse with cool water
- Condition intensively
Cost and Effectiveness
- Cost: £8-20 for products (DIY) or £50-100 at a salon
- Timeline: Immediate—1-3 shades lighter per treatment
- Best for: Lifting dark colours significantly, wanting results quickly

Caution: Bleach is harsh. If your hair is already damaged, this can cause breakage or additional damage. Hair in Southeast England and other hard water regions are more prone to bleach damage. Test on a hidden section first.
Method 5: Professional Colour Stripping (Most Effective, Most Expensive)
Salons use professional-strength colour removers and stripping processes more powerful than home products.
What to Expect
- Cost: £50-150 for a single session, possibly multiple sessions for significant colour
- Timeline: 1-3 sessions, weeks apart
- Results: 1-4 shades lighter per session
Professional stripping is worth the cost if you dyed your hair dark and want it significantly lighter. DIY attempts often fail or cause damage. A professional can assess your hair, choose the right strength product, and ensure even application.
The Reader’s Story: From Dark Brown Disaster to Blonde Again
Emma, Brighton: “I impulsively dyed my long, dyed-blonde hair dark brown. The next day I panicked—I hated it. I tried clarifying shampoo for a week with minimal effect, then bought a colour remover and did two applications myself. That lightened it to medium brown, but it wasn’t enough. I finally went to a professional who did two stripping sessions over four weeks. It cost me £120 total, but I went from dark brown back to light brown that I could re-tone to my desired blonde. It was expensive but much cheaper than getting a permanent blonde correction at a salon immediately.”
Regional Considerations and Water Quality
Hard water regions (Southeast England, parts of Scotland) interact with colour molecules differently. Mineral deposits can make colours appear different and affect how colour removal products work. If you live in a hard water area, use filtered or distilled water for final rinses when removing colour. This ensures you see the true colour without mineral interference.
Common Mistakes to Avoid
Combining Removal Methods Immediately
Don’t use clarifying shampoo, then colour remover, then bleach all within a week. Space out methods by at least 3-4 days and deep condition between treatments. Combining methods rapidly damages hair irreparably.
Ignoring Instructions
Colour removal products have specific timing for a reason. Leaving them in too long doesn’t improve results; it damages your hair. Follow timing exactly.
Not Deep Conditioning Afterwards
All colour removal methods are drying and damaging to some degree. Deep condition immediately after and for 2 weeks following. Your hair’s health depends on this follow-up care.
Attempting DIY on Black or Very Dark Permanent Colour
If your hair is permanently black or extremely dark, DIY removal is unlikely to succeed. Professional services exist because this is difficult. Go directly to a salon rather than wasting money on failed DIY attempts.
Prevention: Avoiding Colour Regrets
This is obvious but worth stating: test temporary colours (semi-permanent or temporary rinses costing £3-8) before committing to permanent dye. You can return hair to original colour or try different shades without permanent commitment.
If you must use permanent colour, do a strand test first. A small hidden section dyed and left for 24 hours shows the true colour without committing your entire head.
FAQ Section
What’s the fastest way to remove hair colour?
Professional salon stripping. A professional can remove 3-4 shades in a single session. DIY fastest methods (bleach washing) take 1-3 sessions and risk damage.
Can I remove dark permanent colour to my natural colour?
Yes, but it requires multiple treatments. Most single treatments lighten 1-2 shades. Dark permanent colour to original light colour requires 3-4 removal sessions.
Will colour remover make my hair orange or yellow?
Colour removers don’t add warmth; they remove colour neutrally. However, as colour lifts, underlying pigment (red, orange, yellow) may show. This is why light blonde is exposed when you remove dark dye. Tone with a toner afterward if needed.
How much does professional colour stripping cost?
£50-150 per session in the UK, varying by salon and location. London costs more (£100-200) than regional areas (£50-100). Multiple sessions total £100-400 for significant colour removal.
Is there a way to fade colour without damaging hair?
Clarifying shampoo and vitamin C are gentlest but slowest. They work well for semi-permanent colours. For permanent colour, some damage is unavoidable with any removal method. Professional services minimise damage through expertise and professional-grade products.
Your unwanted hair colour doesn’t have to be permanent. Methods exist at every price and damage level. For semi-permanent mistakes, clarifying shampoo solves the problem cheaply and gradually. For permanent colour regrets, colour removers offer moderate results with moderate damage. For drastic colour changes, professional stripping costs more but minimises damage and maximises results. Choose based on your specific colour type, the degree of change needed, and your budget.
