Brief summary
The aim of this study is to evaluate, with clinical and biological assessment methods, the effectiveness of the tested cosmetic product applied during 4 weeks of intensive treatment and compared to a Standard Medical Care (medicine shampoo) and to a comparative cosmetic shampoo, on mild to moderate recurrent squamous states of seborrheic dermatitis.
Detailed description
This study is conducted as a monocentric, randomized, controlled and blinded-label study, in parallel groups. A total number of 90 subjects included and randomized in 3 parallel groups: * Test group RV5263A - WS0060 cosmetic product * Comparative group: RV5263A - LC3302 cosmetic product * Standard medical care group 6 visits are planned: * Visit 1: Inclusion (Day 1) * Visit 2: Intermediate visit (Day 4) * Visit 3: Intermediate visit (Day 7) * Visit 4: Intermediate visit (Day 15 ± 1 day) * Visit 5: Intermediate visit (Day 22 ± 3 days) * Visit 6: End-of-study visit (Day 29 ± 3 days)

Eligibility
Inclusion criteria
* Male or Female aged between 18 and 70 years included * Subject affiliated to a social security system or health insurance, or is a beneficiary if applicable * Subject having a squamous state of the scalp: * clinically visible (Squire score ≥ 20), * recurrent (at least twice a year) * having signed their written Informed Consent form (ICF) for their participation in the study and a photograph authorization * Subject having a recent prescription of Standard Medical Care (Ketoconazole 2%) not yet initiated * Subject accepting that according to the randomization, the Standard Medical Care can be possibly replaced by another shampoo, including neutral shampoo * Subject having a maximum usual shampoo frequency of 3/week Non Inclusion criteria * Subject who, in the judgement of the investigator, is not likely to be compliant with study-related constraints and requirements * Subject having any other dermatologic condition than the studied squamous state on hair/ scalp and liable to interfere with the study assessments: * alopecia having caused hair loss on the upper part of the scalp (Norwood Hamilton stage\> III, Ludwig ≥ I-4, alopecia aerata, alopecia totalis) * raised skin lesion, likely to be traumatized, … * Subject having dermatological pathology or evolutive skin lesion on the scalp (contact dermatitis, psoriasis, severe excoriations, severe sunburn, cutaneous bacterial superinfection of the scalp clinically obvious ...) * Topical treatment or product applied on the scalp within 2 weeks before the inclusion or planned during the study that can be active on squamous states or that can limit the effectiveness of the study product: anti-inflammatory drugs, ketoconazole, anti-dandruff shampoo, anti-fungal, rinse with vinegar, essential oils ... * Any scalp dyeing (including henna), bleaching, perm, smoothing / straightening performed within 3 weeks before inclusion or planned during the study * Any topical hair product (conditioner, serum, mask, gel, lacquer, wax, foam…) or water applied on the scalp between the last shampoo and the inclusion visit
