LA BIOSTHETIQUE Frizz Control Smoothing Conditioner RT 150ml

The middle step of La Biosthétique's three-part Frizz Control routine — a 150ml express conditioner that does its work in three to five minutes rather than sitting on the hair like a mask.

The actives

• Cationic guar — a positively charged conditioning agent, drawn to the damaged spots on the hair where frizz starts.
• Rapeseed oil glycerides — plant lipids that smooth and seal the cuticle so the surface lies flat.
• Moisture-binding substances — glycerin and propylene glycol, holding water in the hair so it reacts less to the weather.
• Vegan, and free from silicones, parabens, gluten and palm oil.

How to use it

Not every wash. La Biosthétique specifies after every second or third: distribute through damp hair, leave three to five minutes, rinse. That spacing is part of the instruction rather than a shortcut, and it keeps finer lengths from being weighed down.

Worth knowing

Silicone-free, so the smoothness comes from lipids and guar rather than a sealing film — it builds across the routine instead of landing in one go. It sits between Frizz Control Smoothing Shampoo and the Smoothing Styling Fluid.
