How do I know if my hair is dry?

Dry hair has raised scales and feels rough to the touch. Hairs are porous, dull and feel crunchy. The main cause of this is a lack of sebum, which naturally moisturises the scalp.

What are the benefits of the ingredients in the Nutritive range?

Nutritive hair products contain a vitamin complex, plant-based proteins and Niacinamide to provide dry to very dry hair with essential nutrients and give hair more strength, softness and shine.

What’s the best Nutritive routine for fine, dry hair?

For fine dry hair, we recommend following Bain Satin shampoo with Lait Vital conditioner and Lotion Thermique Sublimatrice blow-dry mist. Then, to nourish dry ends with no greasy finish, apply 5 drops of the Split Ends Serum.

What Nutritive routine do you recommend for thick dry hair?

For thick dry hair, follow Bain Satin Riche shampoo with the Masquintense Riche hair mask. To protect your hair before styling, finish your routine with Nectar Thermique blow-dry milk.

I have a dry scalp, which product would help me?

The Nutri-Supplement Scalp Serum has been designed to hydrate all scalp types, providing a feeling of comfort from the 1st application. Its non-greasy formula preserves the scalp’s protective barrier.
