A bi-phase mist for soft beach waves and sun-exposed hair
Kérastase Soleil Huile Sirène is a bi-phase leave-in mist that creates soft, beachy waves while caring for sun-exposed hair. At the heart of the formula, coconut oil conditions and moisturises the hair fibre, vitamin E helps limit breakage and oxidative damage, and a UV filter adds a layer of protection against the effects of the sun on the lengths. The light, quick-absorbing texture wraps each strand without weighing it down. The result is defined waves with no crunchy feel, extra shine and hair that feels nourished and soft.
The texture
A two-phase mist (oil and water) to shake before use. It sprays lightly, absorbs quickly and leaves a fresh, summery scent.
Who it suits
- Anyone wanting effortless beach waves
- Hair exposed to sun, sea or pool
- Dull, frizzy lengths in summer
- All hair types
Worth knowing before you buy: The mist contains fragrance, silicone (dimethicone) and colourants. Its UV filter protects the hair, not the scalp or skin, so keep using sunscreen and a hat.
How long one bottle lasts
Used a few sprays at a time, three or four days a week, the 150ml bottle lasts a full summer season.
