Let’s get this out of the way, hair botox is safe for coloured hair, so as long as it’s done correctly.
This non-chemical treatment restores shine and strength without stripping your dye, making it ideal for bleached or damaged hair in 2025.
Ever spent hundreds on hair colour only to end up with dry, frizzy strands that won’t behave? Or been told you can’t do treatments right after dyeing? You’re not alone, and the confusion ends here.
Today, the best KSL hair salon will break down how hair botox works on coloured hair, when it’s safe to do it, what to expect during your appointment, and how to maintain results without sacrificing your shade.
Does Hair Botox Fade Coloured Hair?
Hair botox does not fade permanent colour, but timing matters.
Unlike hair rebonding or keratin straightening, hair botox isn’t a chemical-altering process. It doesn’t open the hair cuticle aggressively or strip colour pigments. Instead, it coats and fills hair strands with protein-rich ingredients that lock in shine.
The only risk of fading happens if you apply it immediately after a fresh dye job, especially semi-permanent colours.
Here’s what to do:
- Wait at least 3 days post-colour before getting hair botox
- Avoid clarifying shampoos for 48 hours after the treatment
- Stick to sulphate-free maintenance products
“We always recommend clients wait at least 72 hours post-colouring to get the full benefit of botox without dulling the shade,” – Senior Stylist at REDS Hair Salon, KSL City Mall.
How Does Hair Botox Work on Coloured Hair?
It repairs colour-damaged hair from the inside out, without disrupting your tone.
Hair colouring, especially bleaching or high-lift dyeing, creates microscopic gaps in your cuticle. Hair botox fills those gaps with a blend of hydrolysed keratin, amino acids, oils, and vitamins.
Typical ingredients include:
- Collagen
- Keratin
- Amino acids
- Argan or caviar oil
- Vitamin B5 and E
No formaldehyde. No straightening chemicals. Just deep repair.
Who Should Get Hair Botox After Colouring?
Not everyone should get a hair botox. It’s ideal for those whose coloured hair feels dry, dull, frizzy, or weak.
If your strands feel rough after a hair treatment, or your bleach job left your hair looking fried, hair botox is one of the safest recovery treatments available. It’s most beneficial for:
- Bleached, balayaged, or highlighted hair
- Hair that has gone through multiple colouring cycles
- Frizz-prone or porous strands
- Hair that’s limp, flat, or easily tangled
What it doesn’t do: It won’t straighten your curls or permanently alter your texture, but it will make hair more manageable and healthier.
Ingredients to Avoid in Hair Botox If You Have Dyed Hair
Not all hair botox formulas are colour-safe, some may damage or dull your hair dye. When your hair has been chemically treated or coloured, it’s more sensitive to harsh ingredients.
Here’s what to avoid:
1. Formaldehyde or Methylene Glycol
These harsh preservatives are often found in some older smoothing treatments and can strip hair colour, especially in light or pastel shades. They’re also known to cause scalp irritation or allergic reactions in sensitive individuals.
Look for formaldehyde-free labels or ask your stylist to confirm before proceeding.
2. Harsh Alcohols
Drying alcohols, such as isopropyl alcohol or ethanol can unsurprisingly dehydrate coloured hair, making it feel brittle or rough after the treatment. While not all alcohols are bad (fatty alcohols like cetyl or stearyl are fine), high-alcohol content can fade semi-permanent dyes faster.
3. Ammonia or Peroxide
These are colour-altering agents typically used in permanent dyes or bleaching formulas. Their presence in a hair botox treatment can unintentionally lighten or shift your existing hair colour, especially if heat is applied during the sealing process.
What to Look for Instead
For coloured hair, always choose a gentle, hydrating botox formula that prioritises repair without affecting colour molecules. Ideal ingredients include:
- Hydrolysed keratin (strengthens damaged strands)
- Amino acids (smooth texture without stripping)
- Natural oils like argan, caviar, or jojoba (boost shine and moisture)
- Vitamins B5 and E (nourish dyed hair without dulling the tone)
Tip: Always ask your salon if the treatment is “colour-safe” or specifically designed for chemically treated hair. Reputable stylists (like REDS hair) will use formulas tailored to your hair history.
How Long to Wait After Colouring Before Hair Botox?
We recommend waiting 3–5 days after dyeing to let the colour set before doing botox.
This gives the pigment time to stabilise in your hair cuticle. Doing it too early can cause patchy tone loss, especially with semi-permanent or high-lift shades.
If you’ve bleached your hair, spacing it out also reduces scalp sensitivity during heat sealing.
What Happens During a Hair Botox Appointment?
It’s a 1.5–2 hour process that deeply restores your hair without disrupting colour.
Hair botox may sound complex, but the appointment flow is simple and consistent.Most professional salons follow a structured 5-step protocol:
Step | Description |
Clarifying Wash | Deep cleanses buildup and opens cuticles for absorption |
Botox Application | Applied section-by-section to ensure full strand coverage |
Processing Time | Left on for 30–45 minutes to allow active repair compounds to penetrate |
Heat Activation | A flat iron or steamer seals the treatment into the hair shaft |
Final Rinse + Style | Rinsed, blow-dried, and styled to reveal shine and smoothness |
You can expect the stylist to customise the formula based on your hair condition, especially if it’s been coloured recently.
“The best results come when the stylist adjusts both temperature and formula based on your hair’s porosity and colour level,” Senior Stylist at REDS Hair Salon, KSL.
If your hair has been bleached or double-processed, inform your stylist upfront. This allows them to use a lower heat setting and select a colour-safe variation of the formula.
How Long Does Hair Botox Last on Coloured Hair?
Hair botox typically lasts 6 to 8 weeks, but results depend on how you care for it.
Hair botox is a semi-permanent treatment, not a one-time fix. Its effects fade gradually with each wash, especially if you colour your hair regularly, live in a humid climate, or use hot tools frequently.
Several factors influence how long your hair botox lasts after colouring:
- Hair porosity: Bleached or porous hair absorbs and loses treatments faster
- Shampoo frequency: Frequent washing shortens the effect
- Climate: High humidity breaks down smoothing agents faster
- Styling habits: Regular flat ironing or blow drying accelerates wear-off
Tips to Extend Hair Botox Results
To get the most out of your treatment (and more importantly your money), follow these simple aftercare habits:
✔ Use Sulphate-Free Shampoo & Conditioner
Gentle cleansers protect the treatment’s coating and prevent pigment from fading.
✔ Limit Heat Styling to 2–3 Times Weekly
Excessive heat can reopen the cuticle and break down the bond created by the treatment.
✔ Sleep on Silk or Satin Pillowcases
These reduce friction, preventing frizz and preserving your hair’s smooth texture.
✔ Avoid Chlorine & Saltwater
Swimming can strip both colour and botox ingredients. If you swim, rinse hair with clean water immediately after.
