Keratin Treated Hair Aftercare

If you’ve just treated yourself to a Keratin Blow Dry, especially from a top-tier salon like Live True London, you’ll want to ensure that your silky-smooth results last as long as possible. Keratin treatments infuse your hair with protein that seals the cuticles, reduces frizz, and adds lustrous shine, but the longevity of these benefits significantly depends on how you care for your hair post-treatment. Here are expert aftercare tips recommended by the professionals at Live True London to help you maintain your keratin-treated hair.

  1. Wait Before Washing
    One of the first and most crucial tips from Live True London is to avoid washing your hair for at least 72 hours after your keratin treatment. This waiting period allows the keratin to fully bond with your hair cuticles, ensuring that the treatment sets properly for long-lasting smoothness and shine.
  2. Use the Right Products
    The choice of hair care products post-keratin treatment can make or break your results. Live True London advises using sulphate-free shampoos and conditioners. Sulphates can strip away the keratin coating from your hair, shortening the lifespan of the smooth effects. Instead, opt for products specifically formulated for chemically treated hair, which gently cleanse and maintain the integrity of the treatment.
  3. Minimise Washing Frequency
    To extend the life of your keratin treatment, try to reduce how often you wash your hair. Live True London suggests washing your hair no more than two to three times a week. Over-washing can lead to quicker degradation of the keratin layer. When you do wash, use lukewarm water instead of hot, as high temperatures can also diminish the keratin’s effects.
  4. Avoid Chlorine and Salt Water
    Chlorinated pools and salt water are enemies of keratin-treated hair. Live True London recommends wearing a swimming cap if swimming is unavoidable and thoroughly rinsing your hair with fresh water immediately after swimming. Applying a leave-in conditioner before swimming can also help protect your hair from absorbing harmful chemicals and salt.
  5. Reduce Heat Styling
    Although a keratin treatment will generally reduce your need for heat styling tools thanks to your newly smooth and frizz-free hair, occasional styling might still be necessary. Live True London advises using a heat protectant spray before using any heat styling tools. Also, keep the temperature on these tools as low as possible to prevent heat damage.
  6. Regular Trims
    To keep your hair looking its best, regular trims are essential. This not only helps to keep your hair healthy and free of split ends but also maintains the shape and style of your cut, which enhances the overall appearance of your keratin-treated hair. Live True London stylists can advise on how often you should trim your hair based on its growth rate and condition.
  7. Nighttime Care
    Consider using a silk or satin pillowcase to reduce friction while you sleep, which can help prevent frizz and tangles in your keratin-treated hair. Tying your hair loosely with a silk scarf or using a silk bonnet can also preserve the effects of the treatment, keeping your hair smooth and straight.


Maintaining keratin-treated hair requires thoughtful care and the right products, but with these expert tips from Live True London, you can enjoy your beautiful, smooth, and shiny hair for as long as possible. Remember, investing in good aftercare practices not only helps maintain your treatment but also contributes to the overall health of your hair.
