K18 HeatBounce Conditioning Heat Protectant

Lightweight Conditioning Heat Protection Up to 450°F / 232°C

K18 HeatBounce Conditioning Heat Protectant is a lightweight professional heat protectant designed to defend hair from temperatures up to 450°F (232°C) while conditioning, smoothing and improving manageability.

Powered by Resilicore™ Heat-Shielding Technology, HeatBounce helps protect against damage and breakage caused by blow dryers, flat irons, curling irons and other hot tools while keeping hair soft and manageable.

Choose HeatBounce when preventing future heat damage is the primary objective, rather than waiting until repeated heat styling has already weakened the hair.

HeatBounce or K18 Molecular Repair Hair Oil?

Choose HeatBounce when dedicated heat protection is the main priority. It is designed specifically to condition and protect the hair before blow-drying and hot-tool styling.

Choose K18 Molecular Repair Hair Oil when repair support, frizz control, smoothing and shine are the priorities and you also want heat protection.

You do not automatically need both. For many customers, one well-chosen heat-protective product is enough.

If your hair needs additional finishing after heat styling, HeatBounce can be used before styling and a small amount of Molecular Repair Hair Oil afterward for added smoothing and shine.

HeatBounce or Kevin Murphy HEATED.DEFENSE?

Choose K18 HeatBounce when you want dedicated high-heat protection combined with conditioning and smoothing, particularly as part of a K18 damage-care routine.

Choose Kevin Murphy HEATED.DEFENSE when you want lightweight heat protection that integrates naturally into a Kevin Murphy wash, treatment and styling routine.

Both are logical choices for frequent heat styling. Your existing routine and additional hair concerns can determine which fits better.

What About OLAPLEX?

Choose OLAPLEX No.9 Bond Protector Nourishing Hair Serum when you want lightweight heat protection combined with styling support, satin shine, improved style retention and pollution defense.

Choose OLAPLEX No.5 Leave-In Moisturize & Mend when dry or damaged hair needs substantially more leave-in moisture, split-end support and heat protection from the same step.

Choose HeatBounce when dedicated conditioning heat protection is the priority and you want to remain within the K18 system.

Build Your Heat-Protected K18 Routine

  1. Cleanse: Use DAMAGE SHIELD Shampoo for regular cleansing or PEPTIDE PREP Detox periodically when deeper cleansing is needed.
  2. Condition or Repair: Use DAMAGE SHIELD Conditioner for regular conditioning or the K18 Molecular Repair Hair Mask according to its treatment protocol when structural repair is required.
  3. Protect: Apply HeatBounce before blow-drying or hot-tool styling.
  4. Style: Blow-dry or style with your preferred hot tool.
  5. Finish if Needed: Add a small amount of K18 Molecular Repair Hair Oil when additional frizz control, softness and shine are desired.

Choose Your Routine

Simple Heat Protection:
Regular shampoo + conditioner + HeatBounce

K18 Everyday Protection:
DAMAGE SHIELD Shampoo + DAMAGE SHIELD Conditioner + HeatBounce

Damaged Hair + Heat Styling:
K18 repair routine + HeatBounce

Heat Styling + Frizz/Finish:
HeatBounce before styling + Molecular Repair Hair Oil afterward only when additional smoothing and shine are needed

Can I Use HeatBounce With Other Brands?

Yes. HeatBounce can be used as the dedicated heat-protection step in a mixed-brand routine.

For example, you can use a Kevin Murphy, amika, OLAPLEX, Eleven Australia or Neuma shampoo and conditioner and choose HeatBounce specifically because heat protection is your next concern.

Your routine should be built around what each product contributes rather than requiring every product to carry the same brand name.

How to Use

Apply a small amount evenly through clean, towel-dried hair before blow-drying and brush through to distribute. HeatBounce can also be applied to dry hair before hot tools such as flat irons or curling irons. A little goes a long way.
