LA BIOSTHETIQUE Volume Weightless Conditioner RT 150ml

The second step in La Biosthétique's Volume range, after Volume Strengthening Shampoo. It is an express conditioner built to detangle and condition fine hair without the film that normally comes with it — the whole design problem here is adding slip while leaving the root able to lift.

What's in it

• Tahitian microalgae extract — the range's volume booster, which revitalises and strengthens the hair.
• Rice and soy proteins — balance out structural differences along the length and build resistance.
• Sugar kelp and carrageenan-moss extracts — algae extracts that strengthen and support body.
• Glycerine and pentylene glycol — lightweight humectants that bind moisture without leaving residue.

How to use it

After washing, work it through damp hair, leave it for two to three minutes, then rinse thoroughly. It is an express step, not a mask — leaving it longer does not buy you more. La Biosthétique recommends pairing it with Volume Strengthening Shampoo.

Worth knowing

150ml. In the full Volume routine it sits between the shampoo and the leave-in Strengthening Conditioning Spray, with the Strengthening Repair Mask as the deeper weekly option.
