Description
Protect and detangle dry hair before drying with the Lotion Thermique Sublimatrice from Kérastase Nutritive. This Kérastase heat protection spray protects the fibre up to 230 °C. Hair comes out softer, shinier and easier to style.
Its formula combines niacinamide, plant-based proteins and nourishing lipids. It moisturises, detangles and helps tame frizz. Spray six to ten times onto towel-dried hair, from the lengths to the ends, then comb through. Then dry with a hair dryer or let it air-dry. The Lotion Thermique Sublimatrice can be paired with the concentrate for dry ends from the same range.
It is designed for dry to very dry hair, fine to medium. The title states a 150 ml bottle. This leave-in treatment is aimed at people who dry or straighten their hair often and want a salon routine at home. Its scent is much appreciated.

Our review of this Kérastase heat lotion
Review written by the Aura Capillaire team · Updated on 19 September 2026
We read the feedback from buyers of this Kérastase heat lotion to pick out what comes up most often, good and not so good.
Strong points
- Protection up to 230 °C: before blow-drying, straighteners or tongs.
- Effective detangling, praised by many as soon as they step out of the shower.
- A divine scent, one of the most appreciated points of this treatment.
- A nourishing formula: with niacinamide and plant proteins, for dry hair.
Things to know
- A very fluid texture: it is a spray lotion, not a cream. For very dry, thick hair, add a nourishing treatment from the same range.
- A capacity to check: the title states 150 ml, the technical sheet 250 ml, and some bottles arrived without a cap or unsealed. Check the version and the condition of the bottle on arrival.
Where we lean: for dry hair that often goes under heat, this is a good-quality protecting and detangling treatment. For damaged, brittle hair, the Phyto Repair spray below targets that need. More products await you in our styling sprays.

Kérastase Nutritive, Schwarzkopf Style & Repair, Phyto Repair or Franck Provost All-in-1?
The same heat protection spray comes from several brands. Here is how this Kérastase heat lotion compares with the three other most-requested versions.
| Spray | Protection | Size | Ideal for |
|---|---|---|---|
| Nutritive Kérastase · this lotion |
230 °C | 150 ml | Dry hair |
| Style & Repair Schwarzkopf |

— | 190 ml | All-in-one |
The Schwarzkopf Style & Repair 230 °C protection spray also protects up to 230 °C, in 150 ml. It is aimed at protection and styling. Its listing does not mention nourishing dry hair. The Kérastase lotion adds a real nourishing treatment.
The Phyto Repair heat protection spray protects damaged, brittle hair up to 230 °C, in 150 ml. It is aimed at the care of damaged fibre. It does not target dry hair in particular. The Kérastase is better suited to dehydrated lengths.
The Franck Provost All-in-1 Heat Protection spray is a professional spray that combines several treatments, in 190 ml. It is aimed at a single step before styling. We do not know its maximum temperature. The Kérastase shows clear protection up to 230 °C.
Your questions about this Kérastase heat lotion
Kérastase heat protection spray: is it suitable for fine hair?
The brand designs it for dry hair, fine to medium. Some people with very fine hair find it a little heavy. In that case use six sprays, no more.
Lotion Thermique Sublimatrice for very dry hair?
Yes, it is formulated for dry to very dry hair. It moisturises, detangles and protects from heat. For deeper nourishment, add the concentrate for dry ends from the range.
What is the difference between the Kérastase Nutritive lotion and the Schwarzkopf Style & Repair spray?
Both protect up to 230 °C. The Kérastase also nourishes dry hair with niacinamide and plant proteins. The Schwarzkopf is aimed at simple, everyday protection.
