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.

The shine is exceptional. Use it as the final step of the Rebuild routine for a mirror-like, glass-hair finish: reflective, smooth and glossy, even after heat styling.

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.

LOVE this. I'm so guilty of straightening my hair most days and not always washing between and it's such a faff to dampen hair and put heat spray on each morning. You can literally use this once and it protects against heat till you next wash your hair. Saves me so much time. Warning though, you only need a small small amount, I used way too much the 1st time I used it.

This is stunning but my only criticism is that your hair needs to be damp before you use it, which it should be but im such a sucker for spraying some heat protect in dry hair if I want to curl it the next day. Still such a great product.

Use this every week as part of my haircare routine, put it on after washing my hair and then do my blow-dry as normal but love it! Really helps protect my hair

My hairdresser used this on me and now I am obsessed. Need like 1 squirt of it and it covers my whole head - past shoulder length hair.

Been using this before drying and curling. My hair feels softer afterwards and the style lasts better into the next day and it smells so good
