Keratin Hair Treatment Costs in the UK
Keratin hair treatments use proteins to smooth and straighten hair, reducing frizz and adding shine. UK salons offer both traditional keratin treatments (with formaldehyde) and formaldehyde-free alternatives, with results lasting 3–6 months. Expect consultation, hair assessment, treatment application, processing, and aftercare advice.
✨ The procedure typically takes 2–4 hours including application, processing, and styling, depending on hair length and thickness. Many salons pair keratin treatments with haircuts or colour services, while premium studios include deep conditioning and take-home maintenance products in their pricing.

FAQs
How long does keratin last?
Results typically last 3–6 months depending on hair type and maintenance. Using recommended products extends longevity. Budget around £400–£750 per year for maintenance.
Is formaldehyde-free keratin effective?
Yes—modern formaldehyde-free formulas still deliver smooth, frizz-free results, though they may require slightly more frequent maintenance.
Will it straighten my hair completely?
Keratin smooths and reduces frizz significantly. Very curly hair will still have texture but will be much smoother and more manageable.
Do I need to wait before washing?
Most salons recommend waiting 72 hours before washing to allow the keratin to fully bond. Follow your stylist's specific aftercare instructions.
Conclusion
Keratin hair treatment costs range from £100 standard sessions to £300 premium treatments for long hair, while maintenance packages span £400 to £750. London prices run 40–50% higher than regional cities, so compare salons, commit to packages, and use recommended products so every keratin treatment delivers maximum smooth, manageable hair per pound spent. ✨
