5. Current episode of AA lasting from \> 6 months to \< 10 years prior to screening.
6. No spontaneous improvement in the 6 months prior to screening or between screening and baseline (decrease in SALT score of ≤ 10, \> 10 would be an improvement).

8. Agree not to use any AA treatments during the study (Exception: Chronic treatment with bimatoprost ophthalmic solution for eyelashes and chronic treatment with 5 alpha reductase inhibitors, oral or topical minoxidil).
9. Agree to not use adhesive wigs (other than banded perimeter wigs) during the study
10. Be willing to maintain the same hair style and hair dyeing throughout the study period.
Subjects who shave their scalp must be willing to refrain from shaving their scalp for at least 2 weeks prior to each SALT assessment. Hair trimming outside the treatment areas to maintain the current hair style is permitted.
11. Have active or stable non-segmental VT at screening and baseline defined as follows:
1. Have a clinical diagnosis of non-segmental VT for at least 3 months; and
2. Body surface area (BSA) involvement 4% to 60% excluding involvements at palms of the hands, dorsal aspect of fingers and thumbs including metacarpophalangeal joints, soles of the feet, or dorsal aspect of the feet; and

4. Subjects with active VT should have at least 1 active lesion defined as 1 of the following:
i. New/extending lesion(s) in the past 3 months (confirmed by photographs or medical record); ii. Confetti-like lesion(s); iii. Trichrome lesion(s); iv. Koebner phenomenon/ phenomena (excluding Type 1 \[history based isomorphic reaction\]); e. Coexistence of halo nevus/nevi (also known as Sutton nevus/ nevi) is permitted.
12. If receiving concomitant medications for any reason other than VT, must be on a stable regimen, which is defined as not starting a new drug or changing dosage within 7 days or 5 half-lives (whichever is longer) prior to Day 1. Subject must be willing to stay on a stable regimen during the duration of the study.
13. Must agree to follow the usual and habitual exposure to sun light and not change the use of sunblock and not to use tanning booths, sun lamps or other ultraviolet light sources other than provided/requested by the study team during the study.
You may not be if
Subjects meeting any of the following criteria are ineligible to participate in this study:
1. Participation in an investigational drug or device trial in which administration of an investigational drug or device occurred within 28 days or 5 half-lives of screening, whichever is shorter.
2. Use of live vaccines during the study and within 28 days prior to screening.
3. Known history of chronic alcohol abuse, IV drug abuse or illicit drug abuse within 1 year before screening.
4. Diagnosis or history of malignant disease within 5 years prior to baseline, with the exceptions of basal cell or squamous epithelial carcinomas of the skin that have been resected or cervical carcinoma in situ, with no evidence of recurrence within the 5 years prior to baseline.

2. Chronic (duration of symptoms, signs, and/or treatment of 6 weeks or longer).
3. Viral reactivation of CMV, EBV, VZV or HSV infection requiring systemic therapy in the last 2 years. Periodic HSV viral reactivation (e.g., cold sore) treated with a short course of systemic antiviral therapy within the last 2 years would not be exclusionary.
