   Cohort 2 subjects that have participated in a prior ARQ-154 study:

10. Clinical diagnosis of seborrheic dermatitis of at least 3 months duration as determined by the Investigator.
11. Seborrheic dermatitis of the scalp and/or face and/or trunk and/or intertriginous areas up to ≤20% BSA involvement.

Exclusion Criteria:

1. Planned excessive exposure of treated area(s) to either natural or artificial sunlight, tanning bed or other LED.

    Cohort 1 only:

13. Subjects who experienced an ARQ-154 treatment-related AE or a serious AE (SAE) that precluded further treatment with ARQ-154 foam in a prior ARQ-154 study.

14. Subjects that use any Excluded Medication and Treatments.

    Cohort 2 only:

15. Subjects who cannot discontinue treatment with therapies for the treatment of seborrheic dermatitis prior to the Day 1 visit and during the study according to Excluded Medications and Treatments.

    Cohort 2 subjects that have participated in a prior ARQ-154 study:

17. Subjects who experienced an ARQ-154 treatment-related AE or a serious AE (SAE) that precluded further treatment with ARQ-154 foam in a prior ARQ-154 study.
