LA BIOSTHETIQUE Detangler RT 150ml

The rinse-out spray in La Biosthétique's Long Hair range, 150ml. It is aimed at the particular problem of long hair: the ends are years older than the roots, so they are rougher, and that roughness is what makes a comb catch.

The actives

• Glucose polyphenol — supplies nutrients and works on the hair's structure.
• Rapeseed oil glycerides — plant lipids that smooth and seal the rough sections along the length.
• Erythritol — a humectant, for moisture through the mid-lengths and ends.
• Wheat bran extract — a plant extract included to help keep airborne particles off the hair.
• Serine — an amino acid that limits moisture loss and takes down static.

How to use it

Shake the bottle first — the two phases separate between uses and only work blended. Spray through damp hair after washing, leave it two to three minutes, then comb or finger-detangle from the ends upwards before rinsing it out.

Worth knowing

Vegan, and free from silicones, parabens, gluten and palm oil. Because it rinses away it will not build up on long hair the way a leave-in can, but it also stops working once you are out of the shower. If your ends need help all day, layer a leave-in over the top.
