Replenishing Thermal Care Hair Serum

A lightweight leave-in heat protection serum that shields the hair fibre from blow-dryers, straighteners and curling irons — up to 230°C — helping prevent the dehydration and fragility that heat styling causes.

Made with phyto-keratin to reinforce weakened areas, pracaxi oil to help keep keratin intact, and Zhu Ling mushroom extract to help reduce protein loss and hold your style for longer. It coats hair in a weightless protective film — no residue, no heaviness — leaving it stronger, smoother, frizz-resistant and shiny.

The leave-in step of the Rebuild routine: apply to damp hair before styling, after the Replenishing Shampoo and Replenishing Conditioner. Dermatologically tested, vegan and cruelty-free.

Key ingredients and INCI

Particularly recommended for fragile, weakened, or chemically treated hair, the Replenishing Thermal Care Hair Serum provides effective thermal protection up to 230°C and ensures smooth, silky hair with every use.

The serum is enriched with actives such as:
Phyto-keratin: mimics the hair's natural keratin structure, replenishing it in damaged areas while providing strength and structure.
Pracaxi oil: protects against external agents, keeping keratin intact and preserving hair elasticity.
Zhu Ling mushroom extract: helps reduce protein loss, maintains styling for longer, and protects against heat damage.

Together, phyto-keratin, pracaxi oil and Zhu Ling mushroom extract create a protective film around the hair, shielding it from thermal and environmental stress for longer-lasting styling and visibly healthier hair.
