LA BIOSTHETIQUE Curl Activating Shampoo RT 250ml

The wash step of La Biosthétique's Curl range, in a 250ml bottle. Curly hair loses moisture faster than straight hair because the cuticle sits open along each bend, so a curl shampoo has to clean without stripping. This one is built around that job.

The actives

• Bounce Back Polymer — the polymer shared across the Curl range, deposited during the wash.
• Natural moisturising factors — humectants that hold water in the hair through the rinse.
• Serine — an amino acid that limits moisture loss and reduces static.
• Silicone-free, palm-oil-free, paraben-free and vegan.

How to use it

Wet the hair right through, work the shampoo into the scalp with your fingertips rather than scrubbing the lengths, and let the run-off clean the ends. Rinse thoroughly. Follow with Curl Activating Conditioning Spray on damp hair, or the Curl Activating Repair Mask when the ends need more.

Worth knowing

Silicone-free shampoo feels different in the hand — less slip while you wash, and hair that squeaks slightly before conditioner goes on. That is the formula rather than a fault. It rinses clean instead of coating, which is why the leave-in step matters in this range.
