Primary purpose: TREATMENT

Brief summary: To evaluate the efficacy of either a 1550nm non-ablative fractional laser or a 1927nm thulium fractional laser in the treatment of female pattern hair loss (FPHL).

Detailed description: The study will have a total of eight visits, from baseline (Day 0) to the final follow-up at 3 months following the last treatment. The first visit (Visit 1, Day 0) will be for screening. During this visit, informed consent, HIPAA authorization, and a photo release will be obtained from all participants. Investigators will review the inclusion and exclusion criteria, medical history, and any concurrent medications. A urine pregnancy test will be administered for all eligible subjects. Baseline hair loss will be evaluated and standardized 2D photographs will be taken for future comparison. Hair count, hair density, and terminal hair average diameter will be evaluated as a pre-defined scalp location.. Patients will be randomized to groups (Group A or B).Visits 2 through 5 (Day 30, 60, 90, and 120, ± 5 days) will consist of the treatment phase. Participants will be treated based on which treatment group they were randomized too as below

Eligibility criteria: Inclusion Criteria:

5. Patients with gray hair roots must be willing to dye their gray hair within two weeks of the first appointment and the last 3-month follow-up visit to ensure consistency in evaluator assessments.
6. No use of hair growth treatments or procedures within 6 months prior to enrollment (including hair supplements such as Nutrafol)

8. Pregnancy or planned pregnancy during the study or currently breastfeeding.
9. Any uncontrolled systemic disease
10. History of autoimmune connective tissue disease or thyroid disease.
11. Current use of immunosuppressive medication.
12. Significant history or current evidence of a medical, psychological or other disorder that, in the investigator's opinion, would preclude enrollment into the study.
13. Active dermatitis, metal or other active implants, active infection in the proposed treatment area.
14. Subjects with scarring in the treatment areas (scalp) Subjects with a history of keloids will be excluded.
15. History of bleeding disorder, concomitant use of anticoagulants, history of connective tissue disease, history of Bell's Palsy, epilepsy, smoking, pregnancy, and lactation.
