Everything you need to know about our haircare collection
Stress, seasonal changes, postpartum and age can weaken the hair cycle and visibly impact hair density.
Caudalie's breakthrough VineOxyl™ is the result of years of research into vine-derived molecules. This patented grape-derived active, produced through a two-step enzymatic process, has been studied in relation to the hair follicle environment and helps support the appearance of visibly stronger, denser-looking hair.
Yes. Caudalie’s Hair Density Serum is clinically proven: it improves hair thickness by 87%*, and increases volume by 37%* as demonstrated in a clinical study conducted by a dermatologist.
Yes. Caudalie’s Hair Density Serum is formulated to be suitable during the postpartum period: it is a vegan formula, made with 99% ingredients of natural origin, and has been dermatologically tested.
Caudalie’s Hair Density Serum should be applied daily: use 3 to 4 pipettes section by section across the entire scalp, then massage in with your fingertips. Do not rinse. Note that the dropper fills only halfway — that half-fill counts as one full pipette. It can be applied to dry or damp hair, in the morning before styling or in the evening. For best results, use consistently for 3 to 4 months to give the serum time to work with the natural hair growth cycle.
Both products are formulated with Caudalie’s patented VineOxyl™, but they work at different stages of the haircare ritual. The serum is a leave-in treatment applied daily to the scalp to actively thicken the hair (+87% observed*). The shampoo enhances every wash to support hair density and increase the number of visible hairs**. Used together, they provide complementary results for density and volume.
Caudalie’s Hair Density Serum is designed for thinning or visibly sparse hair. It is effective for hair thinning linked to stress, seasonal changes, aging, and suitable for postpartum period. Its watery serum texture and residue-free formula make it suitable for daily use, even on non-shampoo days.
The Pea and Chia Peptides are the second key active ingredient in Caudalie’s Hair Density Serum. Derived from organic chia seeds (from Peru, Brazil, Bolivia) and French peas, they provide peptides, amino acids, polyphenols, and minerals for an antioxidant, soothing, and hair thickening effect on the scalp. They complement the action of VineOxyl™ on hair density and volume.
No. The serum is designed for both dry and damp hair. Its lightweight, formula absorbs instantly without leaving any greasy residue, so you can apply it daily even if you aren't washing your hair that day.
The denatured alcohol in our serum is a functional ingredient that serves a precise purpose: it helps dissolve the active ingredients, enhances their absorption into the scalp, and delivers a lightweight, non-greasy texture. It is a non-drying form of alcohol, carefully selected to optimize efficacy without compromising scalp comfort.
The serum is specifically formulated for the hair and scalp and has not been tested for use on the face or beard area. We recommend sticking to its intended use to ensure the best results and skin comfort.
