Suitable for: Dry hair, Curly hair, and Colored or highlighted hair

The Madame d'Alexis day serum and night serum duo offers a continuous care cycle: in the morning, the day serum envelops the hair fiber in an ultra-light nourishing veil rich in plant ceramides and organic jojoba oil, creating a heat-protective barrier against UV rays, pollution, and blow-drying.

At night, thenighttime hair serum infuses Damask rose hydrosols, probiotics, and cationic hyaluronic acid to revitalize the scalp, stimulate growth, and strengthen density.

Both areleave-in treatments, 98–99% natural, free from sulfates, parabens, and silicones: they penetrate instantly and leave no greasy residue, even on fine hair.

Designed for all hair types and concerns, this 24-hour duo works in synergy: during the day, it tames frizz, protects color, and preserves shine; at night, it combats hair loss, repairs brittle lengths, and revives dull hair.

André d'Alexis, born in 1910, was an emblematic figure of the diplomatic world. An insatiable traveler, she traveled the world, immersing herself in the cultures and traditions of the countries she visited.
In her quest for the world's beauty rituals, André discovered natural ingredients and ancestral hair care methods. Fascinated, she began experimenting with them, blending traditional knowledge with modern science to create a unique formula. The history of Madame d'Alexis has its roots in these travels.

Anti-hair loss & protection routine: Day & Night Serum

FREQUENTLY ASKED QUESTIONS

Why combine a day serum and a night serum?

The day serum creates a light protective film against UV rays, pollution, and heat, while the night serum regenerates the scalp, stimulates growth, and plumps up the hair fiber. Together, they cover the circadian cycle: active defense during the day, deep repair at night.
Can I apply the day serum to dry hair?

Yes. On dry hair, three drops warmed between the palms instantly tame frizz without leaving any greasy residue. On damp hair, the product penetrates more deeply and optimizes heat protection before blow-drying.
Does the serum damage the root?

No. Its base of organic hydrosols and cationic hyaluronic acid is water-based; it partially evaporates, leaving deep hydration without a greasy film. When you wake up, your scalp remains fresh and your volume intact.
Should I massage my scalp after applying the night serum?

A one-minute massage using circular movements improves microcirculation and promotes the diffusion of probiotics and nettle extracts, amplifying their anti-hair loss and densifying effects.
Are both serums suitable for fine hair?

Absolutely. Leave-in formulas are ultra-lightweight and free from occlusive silicones; they don't weigh down the roots and leave natural volume intact, while strengthening the hair fiber.
How long does it take to see a densifying effect with the night serum?

The first signs, such as more flexible roots and reduced hair loss, often appear after just one month of use. The visible density can be fully appreciated after a complete growth cycle, i.e., two to three months of daily use.
