Night Serum vs. Classic Hair Serum: What's Different for the Scalp

A traditional hair serum is usually applied to the lengths of the hair as a finishing touch. The Night Serum is applied directly to the scalp in the evening and does not need to be rinsed out: it is a nighttime scalp treatment.

This formula contains no added water: its aqueous phase consists of organic hydrosols with a physiological pH, which hydrate, soothe, provide comfort, and reduce irritation. Cationic hyaluronic acid provides deep hydration and a plumping effect, resulting in hair that looks thicker.

The Microbiome at the Heart of Healthcare

Probiotics and postbiotics help restore balance to the scalp’s microbiome. Fermented extracts support cellular vitality and nighttime repair. Extracts of oak, nettle, and licorice strengthen the hair’s resilience and density.

A pipette, line by line

In the evening, apply one pipetteful directly to the scalp, section by section, then massage in. Do not rinse. Use on a dry or slightly damp scalp 3 to 5 times a week as an intensive treatment, then 1 to 2 times a week for maintenance, ideally after using Le Scrub.
