Could your own hair follicles cure baldness? new trial begins
NCT ID NCT07107841
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a treatment called autologous hair follicle secretome (aHFS) for androgenic alopecia (common baldness). The treatment is made by taking hair follicles from the person, growing them in a lab, and collecting the substances they release. These are then injected into the scalp over a year. The trial involves 60 people and compares the active treatment to a placebo. The goal is to see if it safely increases hair density and thickness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Inclusion Criteria * SUBJECTS MUST BE ON A STABLE COURSE OF MINOXIDIL (ORAL OR TOPICAL) AND/OR 5-ALPHA REDUCTASE INHIBITORS. THEY MUST HAVE BEEN ON THE SAME 5-ALPHA REDUCTASE INHIBITOR FOR ≥12 MONTHS PRIOR TO BASELINE. * FEMALE SUBJECTS MUST NOT BE ON HAIR GROWTH MEDICATIONS OR TOPICALS FOR ≥6 MONTHS PRIOR TO BASELINE. * TESTOSTERONE REPLACEMENT THERAPY (TRT) IN ANY FORM (E.G. DEPO-, INJECTABLE, TOPICAL, PATCHES, NASAL GEL, ORAL, PELLET ETC.) IS ALLOWED AS LONG AS SUBJECT HAS BEEN ON A STABLE COURSE (IN THE OPINION OF THE INVESTIGATOR) OF TRT FOR ≥12 MONTHS. * Biological sex: Male and Female (up to n=20 males and up to n=10 females will be in each arm for a total of up to n=40 males and up to n=20 females) * Age: ≥18 - 65 years * Subjects with Androgenic alopecia * No intention to start new hair growth medications and no intention to change the dosage or usage of minoxidil or 5-alpha reductase inhibitors until the end of their participation in the trial. * Competent and willing to provide written, informed consent to participate in all study activities. * Willing and able to tolerate multiple injections of the study product. * Must be able to attend all study related clinical visits. * Willing to maintain the same hair style as at the Screening Visit for the duration of the study. * Must be willing to have small (diameter similar to a pencil lead) UV (invisible) or red colored tattoo dots applied to scalp (up to 5) and touch up tattoos if necessary. UV tattoo dots only show under black light. Subjects will chose UV or red. Exclusion Criteria * Subjects with clinical diagnosis of alopecia areata or other non-androgenic forms of alopecia. * Active skin disease (Psoriasis or severe seborrheic dermatitis) of the scalp * Scalp infection * Severe active systemic infection * Cuts or abrasions on the scalp * History of surgical hair restoration in the last 12 months. * Current or recent (within last 5 years) malignancy (except basal cell and squamous cell skin cancers) * History of systemic chemotherapy or radiation * History of thyroid dysfunction * History of autoimmune disorder (specifically Graves disease, Hashimoto thyroiditis, or systemic lupus erythematosus) * Continuous/daily use of nonsteroidal anti-inflammatory or Vitamin E, unless discontinued within 7 days before 1st treatment and only used as needed through the trial period. * Use of any medications that potentially cause drug-induced hair loss (e.g., depo-testosterone, haloperidol, methotrexate, methylprednisolone, prednisone, testosterone, divalproex sodium) within the last 3 months. * Known allergy or sensitivity to tattoo ink. * Current anticoagulant therapy (heparins; factor Xa inhibitors; direct agents such dabigatran, rivaroxaban, apixaban, edoxaban and betrixaban; warfarin/coumarins) * Significant tendency to develop keloids or hypertrophic scarring * Subjects unable to communicate with the investigator and staff * Any health condition that in the investigator's opinion should preclude participation in this study
