You’ve just invested in a luxurious keratin treatment. Your hair looks sleek, feels smooth, and for once, has zero frizz. But how do you keep it that way?

Without proper care, the benefits of a keratin treatment can fade fast. Harsh shampoos, frequent washing, or heat overuse can strip the protein right out of your strands.

At Haste Hair in Boston, we’ve helped hundreds of clients maintain their keratin-treated hair with targeted aftercare strategies. Whether you’re navigating New England humidity or wondering when to wash, we’ve got answers.

In this guide, you’ll learn what to do (and avoid) after a keratin treatment, including product tips, deep conditioning hacks, and when to rebook.

With the proper care, your results can last up to 3 months or longer. Let’s make that smooth, shiny finish last.

What Is Keratin-Treated Hair?

Keratin-treated hair has undergone a smoothing process that infuses the hair shaft with keratin, a natural protein. The result? Reduced frizz, improved shine, and more manageable hair.

1. How to Wash Keratin-Treated Hair (and When)

Timing your first wash is crucial. Most treatments require waiting 72 hours before shampooing to allow the keratin to bond fully.

Tips:

  • Wait 3 days before your first post-treatment wash.
  • Use sulfate-free shampoo and conditioner only.
  • Sleep on a silk pillowcase to reduce friction.

Bonus: For added protection, try a nourishing deep conditioning treatment once a week to lock in moisture.

2. Products to Avoid After a Keratin Treatment

Some ingredients can undo your smooth results. Say no to:

  • Sodium chloride (common in sea salt sprays)
  • Alcohol-based styling products
  • Clarifying shampoos (unless used weeks later to remove buildup)

Looking for heat styling options? Use a Kerastase heat protectant before blow-drying or flat-ironing.

3. How Often to Wash

Washing too often can shorten your treatment’s lifespan.

  • Aim for 2–3 times a week max.
  • Use dry shampoo to refresh in between.
  • Rinse with cool water to help seal the cuticle.

4. Blow-Drying, Curling & Styling Tips

FAQ

Can I work out or exercise after a keratin treatment?

It’s best to avoid sweating the scalp early on, as it may break the keratin seal. If you need to exercise within the first 72 hours, tie your hair loosely and use dry shampoo after.

Can I swim after keratin treatment?

Avoid chlorine and saltwater for at least 2 weeks. If necessary, wet your hair with fresh water beforehand or wear a swim cap. Always rinse and use a sulfate-free shampoo immediately after.

Can I deep condition my keratin-treated hair?

We recommend using a deep conditioner once a week. It will strengthen the hair and make it more manageable.

How long does it take for a keratin treatment to settle in?

It takes at least a week for a keratin treatment to settle in.
