If you’ve just stepped out of the salon after getting hair rebonding in Bangkok, you’re probably loving the sleek, shiny, and perfectly straight look. At The Hills BKK, we see that post-rebonding glow every day, and we know how important it is to keep that fresh-from-the-salon style for as long as possible.

Hair rebonding is a chemical treatment that restructures your hair bonds to make it permanently straight until new hair grows. While the results are beautiful, they also require proper aftercare to maintain smoothness, prevent damage, and prolong the treatment’s life.

Whether you’re new to rebonding or a regular at The Hills BKK, here’s your ultimate guide to post-rebonding hair care that truly works.

1. Give It 72 Hours Before Washing

After rebonding, your hair needs time to “set” into its new structure. Washing it too soon can weaken the treatment and cause your hair to lose its perfect straightness.

Why 72 hours is important:

The chemicals need to stabilize and bond with your hair.
Washing too early can make your hair revert to waves or frizz.

Pro Tip from The Hills BKK: During these first 3 days, avoid tying your hair in ponytails, clipping it up, or tucking it behind your ears. Even these small actions can create bends or marks in freshly rebonded hair.

2. Switch to Sulfate-Free Products

If you want your hair rebonding Bangkok results to last, ditch regular shampoos and conditioners with sulfates. Sulfates are harsh detergents that strip natural oils and moisture from your hair, leaving it dry and brittle.

What to look for instead:

Sulfate-free shampoos for chemically treated hair.
Conditioners with keratin, argan oil, or coconut oil.

At The Hills BKK, we recommend salon-grade products specifically formulated for rebonded hair. They help lock in smoothness and prevent dryness.

3. Deep Condition Weekly

Rebonding can reduce your hair’s natural moisture, making it more prone to dryness and breakage. That’s why weekly deep conditioning is a must.

How to do it right:

After shampooing, apply a generous amount of deep conditioning mask.
Wrap your hair in a warm towel for 15–20 minutes.
Rinse with cool water to seal the cuticles.

4. Avoid Heat Styling (for Now)

Your hair is already straight there’s no need for additional heat from straighteners or curling irons. Too much heat can damage your hair cuticles, making your hair lose its shine and become frizzy.

If you must blow-dry your hair:

Use the cool air setting.
Keep the dryer at least 15 cm away from your hair.
Always apply a heat protectant spray.

5. Protect Hair While Sleeping

You might not realize it, but your pillowcase could be sabotaging your smooth hair. Cotton pillowcases create friction, which can lead to frizz and tangles.

The fix:

Switch to a silk or satin pillowcase.
If that’s not an option, wrap your hair in a silk scarf before bed.

6. Schedule Regular Trims

Even perfectly straight hair can develop split ends over time. Trimming your hair every 6–8 weeks keeps it looking healthy and prevents splits from traveling up the strand.

At The Hills BKK, our stylists combine trims with nourishing treatments to keep rebonded hair in top condition.

7. Avoid Chlorine and Saltwater

Both chlorine (in swimming pools) and saltwater (at the beach) can weaken your rebonding treatment and dry out your hair.

If you can’t avoid swimming:

Wear a swim cap.
Rinse hair immediately after swimming.
Apply a leave-in conditioner before getting into the water.

8. Oil Your Hair the Right Way Natural oils like coconut, argan, or almond oil can work wonders for post-rebonding care, but timing is everything.

Wait at least one week after rebonding before oiling your hair.
Apply a small amount to the mid-lengths and ends—avoid the roots to prevent greasiness.
Leave it on for 30–60 minutes before washing.

9. Plan Your Next Touch-Up

On average, rebonding lasts 6–9 months depending on your hair growth rate and aftercare routine. The key is to touch up only the regrown portion of your hair, not the entire length, to prevent overprocessing.

Our stylists at The Hills BKK will help you plan your next appointment so your style stays sleek without causing unnecessary damage.
