Quick answer
A keratin treatment typically lasts about three to five months. It smooths the hair and reduces frizz, and gradually wears off with washing as your natural hair grows through at the roots.
How long yours lasts depends on your hair type, the product used, how often you wash your hair and whether you use sulphate-free products. Swimming in chlorine or salt water and frequent washing tend to shorten the result.
Step-by-step guidance
- Ask the stylist which product they use and whether it contains or releases formaldehyde, and whether the salon is well ventilated.
- If you are pregnant, breastfeeding or have a scalp condition, check with your doctor before booking.
- Follow the salon's instructions on when you may first wash, tie up or clip your hair.
- Switch to sulphate-free shampoo and conditioner and wash less often if you can.
- Book a repeat treatment only once the previous one has mostly worn off.
What to check
- The product name and its ingredients
- How long the appointment takes
- Aftercare rules for the first few days
- Whether the treatment suits coloured or chemically relaxed hair
- Whether the salon has good ventilation during the blow-dry and flat-iron stage
Common mistakes to avoid
- Washing hair too soon after the treatment
- Using shampoos with sulphates
- Swimming often without protecting the hair
- Repeating treatments too close together
- Tying hair up tightly or tucking it behind your ears in the first few days

Frequently asked questions
Is keratin treatment permanent?
No. It is semi-permanent and gradually washes out over a few months.
Can I colour my hair after a keratin treatment?
Many stylists suggest colouring before the treatment or waiting a couple of weeks after, so ask your stylist.
Can I have a keratin treatment while pregnant?
Check with your doctor first, as some keratin products release fumes you may want to avoid.
