A kerato-reducing shampoo for stubborn, flaking dandruff
Lazartigue Clear DS Kerato-Reducing Anti-Dandruff Shampoo is an anti-dandruff shampoo for scalps with stubborn, visible flaking that needs a stronger approach. Lazartigue is a French hair-care specialist that has run Paris hair salons since 1880 and formulates most of its care with a high share of natural-origin ingredients. This Clear DS shampoo is formulated to help reduce the buildup of skin cells behind stubborn, visible flaking, going further than a standard anti-dandruff shampoo for persistent cases.
The texture
A treatment shampoo that lathers and is left on briefly before rinsing, for a more concentrated action on the scalp.
Who it suits
- Stubborn, visible flaking that a regular shampoo hasn't fixed
- Scalps needing a more concentrated anti-dandruff routine
- Alternating with a gentler shampoo between treatments
- Pairing with the Clear DS gel for flare-ups
Worth knowing before you buy: Persistent or worsening flaking, redness or itching that doesn't improve is best looked at by a specialist rather than managed with shampoo alone.
