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

A classic hair serum is generally applied to the lengths of the hair as a finishing touch. The Night Serum is applied directly to the scalp at night and is not rinsed out: it is an overnight scalp treatment.

Its 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 visibly thicker hair.

The Microbiome at the Heart of Treatment

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 dropper, drop by drop

At night, apply one drop directly to the scalp, section by section, and then massage it in. Do not rinse. Apply to a dry or slightly damp scalp 3 to 5 times a week during treatment, and then 1 to 2 times a week for maintenance, ideally after using Le Scrub.

How to Choose Your Nighttime Hair Serum?

A treatment designed for the scalp

A scalp treatment is applied directly to the skin, section by section, and is not rinsed off.

Ingredients for the Microbiome

For a sensitive, dry, or itchy scalp, look for ingredients that rebalance the microbiome—such as probiotics and postbiotics—and soothing ingredients, such as organic hydrosols.

Resources for Visual Density

Cationic hyaluronic acid provides a plumping effect and makes hair appear thicker; extracts of oak, nettle, and licorice strengthen the hair and increase its density.

A Transparent Formula

No added water, 98% naturally derived ingredients, free of sulfates, silicones, and parabens, with 100% natural fragrance.

Who is our nighttime hair serum intended for?

Sensitive, dry, or irritated scalps

Hair that lacks strength and density

Extracts of oak, nettle, and licorice strengthen the hair's resilience and density: when you wake up, your roots are stronger.

Hair that lacks shine and vitality

The treatment adds shine, softness, and vitality.
