Collection: Leave-In Hair Treatments

LOYA leave-in hair treatments provide targeted care that stays with your hair after washing. Created for dry, dull, frizzy, brittle or visibly damaged strands, these lightweight formulas help improve softness, smoothness and resilience without leaving the hair greasy, sticky or weighed down.

Ultra Strands Leave-In is the collection’s restorative treatment for everyday damage. Its patented fungi-derived Hair Protection Technology helps reinforce the cuticle and shield strands from environmental stress and heat styling. A 3-in-1 Hair Restoration Complex with shikimic acid, arginine and malic acid supports the hair’s structure, while biotin and rice-derived conditioning technology help strengthen, soften and enhance shine.

The formula creates a light protective veil around the hair, helping smooth frizz, improve the look of split or stressed ends and leave lengths feeling more manageable. It is suitable for a wide range of hair types and textures, including colour- or keratin-treated hair, and can be used whenever hair needs added softness, polish and protection.

Like every LOYA ritual, the experience connects visible performance with emotional wellbeing. Swiss science-led hair technology addresses the signs of damage, while HappyFeelBoost™ gives the application a soft sensorial quality designed to support a more positive mood. It is a lift for your hair and a more rewarding pause in your day.

Work a small amount through damp or dry hair before styling and do not rinse. Adjust the amount to suit your hair’s length and density. Use daily when needed, concentrating on areas that feel dry, rough or prone to frizz. For care from root to length, apply a targeted LOYA scalp serum first, then follow with the leave-in treatment through the hair.

Explore LOYA leave-in hair treatments for effortless daily care that helps hair look smoother, feel stronger and stay protected between washes.
