LA BIOSTHETIQUE Frizz Control Smoothing Styling Fluid RT 150ml

The leave-in that finishes La Biosthétique's Frizz Control routine — 150ml of a light serum worked through towel-dried hair before styling, so the smoothing is in place before heat or air gets to it.

The actives

• Natural sugar polymers — acacia senegal gum and pullulan, which coat the hair and give flexible hold without a cast.
• Cationic guar — a conditioning agent that improves combability and takes the static out.
• Moisture-binding substances — glycerin, panthenol, trehalose and sorbitol, holding water in the hair so it swells less in humidity.
• Vegan, and free from silicones, parabens and palm oil.

How to use it

After washing, work it through towel-dried hair with your hands, concentrating on the bottom lengths and ends where frizz shows most. Leave it in and style as usual — blow-dry, straighten, or let it dry naturally.

Worth knowing

It is a fluid rather than a cream, so it disappears into the hair instead of sitting on it — useful on fine hair that a smoothing cream would flatten. Denatured alcohol in the formula is what makes it dry down quickly. Designed to follow Frizz Control Smoothing Shampoo and Smoothing Conditioner.
