Inclusion Criteria:

• Subjects of any gender, age 18 years or older, at the time of informed consent at Screening
• Subjects who are willing and able to adhere to the study visit schedule and comply with protocol requirements.
• Subject self-reports active CA (LPP/FFA or CCCA). for at least 6 months from screening visit. Diagnosis will be confirmed clinically at screening visit.
• Subject has a negative Tuberculin purified protein derivative (PPD) or QuantiFERON TB-Gold test (QFT) at screening.
• Subject is judged to be in otherwise good overall health following a detailed medical and medication history, physical examination, and laboratory testing.

Exclusion Criteria:

• Subject's cause of hair loss is indeterminable and/or they have concomitant causes of alopecia, such pregnancy-related, drug-induced, telogen effluvium, or advanced androgenetic alopecia.
• Subject has a history of CA for ≥ 7 years since their disease onset, severe fibrosing disease, or very rapid hair loss.
• Subject has a history of moderate to severe keloids on the scalp, as determined by clinical examination at screening.
• Other scalp disease that may impact assessment (eg, scalp psoriasis, dermatitis, etc).
• Subject is pregnant or breastfeeding. Female subjects of childbearing potential must agree to use two effective methods (one of which is a highly effective method) of contraception throughout the study and for at least 28 days after the last dose of investigational product. Women of childbearing potential must test negative for pregnancy prior to enrollment in this study.
• Participation in other studies involving investigational drug(s) within 8 weeks or within 5 half-lives (if known), whichever is longer, prior to study entry and/or during study participation.
• Active systemic diseases that may cause hair loss (eg, systemic lupus erythematosus, thyroiditis, systemic sclerosis, lichen planus, etc).
• Any Psychiatric condition in the opinion of the investigator precludes participation in the study .
• Current or recent history of clinically significant severe, progressive, or uncontrolled renal (including but not limited to active renal disease or recent kidney stones), hepatic, hematological, gastrointestinal, metabolic, endocrine (particularly thyroid disease which can be associated with hair loss), pulmonary, cardiovascular, psychiatric, immunologic/rheumatologic or neurologic disease; or have any other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration, or interfere with the interpretation of study results; or in the opinion of the investigator, the subject is inappropriate for entry into this study, or unwilling/unable to comply with STUDY PROCEDURES.
• Any present malignancies or history of malignancies with the exception of adequately treated or excised non-metastatic basal cell or squamous cell cancer of the skin or cervical carcinoma in situ.
• History of any lymphoproliferative disorder such as Epstein Barr Virus (EBV) related lymphoproliferative disorder, history of lymphoma, history of leukemia, or signs and symptoms suggestive of current lymphatic or lymphoid disease.
• History (single episode) of disseminated herpes zoster or disseminated herpes simplex, or a recurrent (more than one episode of) localized, dermatomal herpes zoster.
• History of systemic infection requiring hospitalization, parenteral antimicrobial therapy, or as otherwise judged clinically significant by the investigator within 6 months prior to Day 0.
• Active acute or chronic infection requiring treatment with oral antibiotics, antivirals, antiparasitics, antiprotozoals, or antifungals within 4 weeks prior to Day 0 or superficial skin infection within 1 week prior to Day 0.
• Significant trauma or major surgery within 1 month of signing informed consent.
• Considered in imminent need for surgery or with elective surgery scheduled to occur during the study.
• Active hepatitis B, hepatitis C, human immunodeficiency virus (HIV), or positive HIV serology at the time of screening for subjects determined by the investigators to be at high-risk for this disease.
• Have an active history of alcohol or substance abuse within 1 year prior to Day 0.
• Donation of blood in excess of 500 mL within 8 weeks prior to Day 0.
• Subject has received a live attenuated vaccine ≤ 30 days prior to study screening.
• Subject has any uncertain or clinically significant laboratory abnormalities that may affect interpretation of study data or endpoints, at determined by the PI.
• History of adverse systemic or allergic reactions to components of study drug.
• Use of systemic immunosuppressive medications, including, but not limited to, cyclosporine, systemic or intralesional corticosteroids, mycophenolate mofetil, azathioprine, methotrexate, within 8 weeks prior to baseline visit.
• Use of other systemic agent for CA, including, 5α-reductase inhibitors, hydroxychloroquine, or retinoids, within 4 weeks prior to baseline visit.
• Use of an intralesional corticosteroids or oral JAK inhibitor (tofacitinib, ruxolitinib) within 4 weeks prior to the baseline visit.
• Subject has used topical corticosteroids, and/or tacrolimus, and/or pimecrolimus within 1 week before the baseline visit.
• Subject has been previously treated with biological drugs in the last 12 weeks for other indications.
• Subjects previously tested with a positive or indeterminable PPD or QFT result, including subjects that completed standard tuberculosis therapy.
• Screening 12-lead ECG that demonstrates clinically significant abnormalities requiring treatment, e.g acute myocardial infarction, serious tachy or brady arrhythmias or that are indicative of serious underlying heart disease (e.g. cardiomyopathy, major congenital heart disease, low voltage in all leads, Wolff-Parkinson-White syndrome and other clinically relevant abnormalities which may affect participant safety or interpretation of study results. A history of additional risk factors for Torsades de Pointes (TdP) (e.g. heart failure, hypokalemia, family history of long QT syndrome).
• If QTcF exceeds 450 mS, or QRS exceeds 120 mS, the ECG should be repeated 2 more times and the average of 3 QTc or QRS values should be used to determine the participants' eligibility. Participants with average screening value QTcF > 450 mS should be excluded. Concomitant use of medications that prolong the QT/QTcF interval is exclusionary.
• Use of concomitant drugs that prolong the QT interval at the judgment of the PI
