The Black Seed & Argan Elixir Shampoo by Byou Cosmétiques is a true 98% natural shampoo that turns your hair care routine into a precious moment of self-care. This concentrated formula combines three exceptional actives renowned for their hair benefits: strengthening black seed oil, nourishing organic argan oil and hydrating aloe vera. A cleansing elixir that gently washes while caring for your hair and scalp, even the most sensitive.

The exceptional benefits of black seed oil and organic argan for your hair

Black seed oil, one of nature's treasures, is renowned for soothing sensitive scalps and helping to strengthen the hair fibre from root to tip. Paired with organic argan oil, it forms a powerful duo that deeply nourishes dry and damaged hair. Argan brings suppleness, shine and natural softness, while aloe vera completes this synergy by intensely hydrating and making hair easier to style. This unique combination makes this shampoo a strengthening treatment for all hair types, particularly suited to coily, curly or fragile hair. To complete your natural hair care routine, discover our 2-in-1 hair regrowth and anti-hair-loss serum, which works in synergy with this elixir shampoo.

A gentle, natural formula for everyday use

The cleansing base of this shampoo has been specially formulated to cleanse without stripping the scalp and hair. With 98% natural-origin ingredients, this formula respects your hair's natural balance and is perfect for everyday use. The carefully selected plant actives provide hydration, nourishment and protection without weighing hair down. This natural elixir shampoo leaves your hair light, supple and delicately scented, while respecting even the most sensitive scalps.

How to use your elixir shampoo for the best results

Apply a small amount of shampoo to wet hair and gently massage the scalp with your fingertips to boost microcirculation. Leave on for a few moments so the black seed and organic argan oils can release all their benefits, then rinse thoroughly with lukewarm water. Repeat if necessary for a deep cleanse. For a complete hair care routine, explore our range of natural shampoos suited to every need. This 300ml bottle will see you through several weeks of regular use, giving your hair all the benefits of a true natural hair elixir carefully formulated by Byou Cosmétiques.

Efficace sur psoriasis

Ayant du psoriasis assez sévère sur le cuir chevelu, j'ai eu une sensation de nettoyage "profond", un cuir chevelu assaini. J'avais moins de démangeaisons après le lavage.
Petit plus : le shampooing sent très bon.
