A sulfate-free shampoo that clears oily flakes and keeps them away
Ducray Kelual Squanorm Oily Dandruff Treatment Shampoo is a flake-care shampoo for oily flakes, the thick, yellowish flakes that stick to a greasy scalp. Its Probiotic-Science approach uses piroctone olamine and glyceryl laurate to remove 100% of visible flakes from the first wash and to help keep them away for up to two months. Succinic acid helps regulate excess sebum, and bisabolol soothes the scalp. Hair is left soft, light and with more volume.
The texture
A fluid shampoo that lathers gently thanks to its sulfate-free cleansers and rinses out easily.
Who it suits
- Oily flakes with a greasy, uncomfortable scalp
- Flakes that keep coming back after regular shampoos
- All hair types, from 12 years old
- People who want a sulfate-free flake-care routine
Worth knowing before you buy: for dry, fine white flakes, the Squanorm moisturizing shampoo for dry flakes is the right match. Very flaky, red-looking scalps need the stronger Kelual DS shampoo.
How long one bottle lasts
At three washes a week for two weeks, then once a week, the 400ml bottle lasts around four to six months.
