In front of the mirror at our hair salon in Sitges, many clients ask us the same question: which treatment is better for my hair, hair botox or keratin? The honest answer is: it depends on what you need. Both are high-end hair treatments, but they work in different ways and address different problems.
Choosing the wrong treatment not only means an unnecessary expense — it may simply not deliver the results you’re hoping for. That’s why in this article we explain in depth the differences, the benefits, and the cases where each one truly shines. And if you’re unsure, our beauty centre in Sitges offers a personalised consultation with no obligation.
What is hair botox?
Despite its name, hair botox contains no botulinum toxin. The term is a metaphor: just as facial botox “fills in” wrinkles, hair botox fills the damaged spaces in the hair fibre with nutrients, proteins and hyaluronic acid.
It is an intensive hydration and nourishment treatment that works from within the hair, rebuilding the internal structure and restoring elasticity, softness and shine to damaged hair. The effect lasts between 3 and 5 weeks and is especially recommended if your hair undergoes frequent colouring or bleaching at our salon.
What is a keratin treatment?
Hair keratin is a protein that forms part of the natural structure of hair. Keratin treatments supply this protein externally to straighten, smooth and control frizz on a long-lasting basis.
Unlike hair botox, professional keratin always involves the use of heat (a flat iron at high temperature) to seal in the treatment. The result is smoother, shinier and more manageable hair that can last between 3 and 6 months.
Key differences: hair botox vs keratin
To understand which treatment suits you best, the clearest approach is to compare them side by side:
| Feature | Hair botox | Keratin |
|---|---|---|
| Main purpose | Nourishment & repair | Straightening & frizz control |
| Straightens hair | Partially | ✓ Yes |
| Repairs hair damage | ✓ Yes | Partially |
| Provides hydration | ✓ Intensive | Moderate |
| Requires heat (flat iron) | Not always | ✓ Always |
| Duration of effect | 3 – 5 weeks | 3 – 6 months |
| Suitable for very damaged hair | ✓ Ideal | With caution |
| Compatible with recent colouring | ✓ Yes | Wait 2–3 weeks |
| Result on curly hair | Softens the curl | ✓ Intense straightening |
Which one to choose based on your hair problem?
Choose hair botox if…
- Your hair is dry, dull or lifeless and needs urgent nourishment.
- You’ve had bleaching or highlights recently and your hair is weakened.
- You have fine hair and are looking for more body and elasticity without adding weight.
- You want a treatment that’s compatible with colouring without waiting.
Choose keartin if…
- Your hair is very curly or very frizzy and you want long-lasting straightening.
- You want to cut down on drying and styling time in your daily routine.
- You live in a humid environment and your hair puffs up easily.
- You want a treatment whose effect lasts several months without frequent maintenance.
Aftercare: how to maintain your results
Whether you choose hair botox or keratin, home care makes the difference between results that last weeks and results that fade within days:
- Use sulphate-free, salt-free shampoo, especially after keratin.
- Apply a nourishing hair mask at least once a week.
- Wash your hair with lukewarm water, not hot.
- After keratin, wait at least 72 hours before the first wash.
- Always use a heat protectant before applying any heat styling tool.
Frequently asked questions
How long does the hair botox effect last?
Hair botox lasts an average of 3 to 5 weeks. To keep your hair consistently nourished, we recommend repeating it every month to six weeks, alongside nourishing masks at home.
Does keratin damage hair?
When applied professionally and with quality products, keratin does not damage hair. At Raffel Pagès Sitges we use formaldehyde-free formulations that respect the integrity of the hair fibre. We always assess the condition of your hair before proceeding.
Can you colour your hair after keratin?
Yes, but it’s advisable to wait 2 to 3 weeks after the keratin treatment before colouring, so the treatment settles properly and the colour takes evenly.
Does hair botox straighten hair?
Hair botox can reduce frizz and tame volume, but it is not a straightening treatment as such. If the main goal is long-lasting straightening, keratin is the more suitable option.
How much does the treatment cost at Raffel Pagès Sitges?
The price varies depending on the length and condition of your hair. Contact us for a personalised quote.
There is no universally better treatment. Hair botox is the ideal choice if your hair needs nourishment, hydration and repair. Keratin is the answer when you’re looking for long-lasting straightening and frizz control. And in many cases, a combination of both can be the smartest strategy.
