Most Helpful Review

Why You’ll love it

Lock in the style you love before you even start styling.

Helps curls and waves stay bouncy, not flat by lunchtime.

Gives smooth, brushable hold without crisp, sticky strands.

Supports heat protection so hair feels soft, not frazzled.

Description

KMS Therma Shape Hot Flex Spray is a heat-activated styling mist that locks in shape with every blow-dry.

This clever spray works with your hairdryer or hot tools, setting curls, waves, or smooth styles so they last longer. It lightly coats each strand to help protect against heat, while giving flexible hold that doesn’t feel stiff.

The fine mist feels weightless on the hair and dries quickly, leaving a smooth, touchable finish with a soft, salon-fresh scent. Hair feels polished yet movable, not crunchy or sticky.

Perfect for those who style with curling wands, straighteners, or blow-dry brushes, and want shape that stays from morning to night. Use on damp or dry hair whenever you heat-style for longer-lasting texture and control.

Directions

How To Use KMS Therma Shape Hot Flex Spray

Comb through to distribute the product.
Blow-dry hair, shaping with a brush for smoothness or volume.
For stronger curls or waves, follow with a curling wand or iron.
