Evidence-Based Integrated Protocol to Maximize Hair Follicle Survival in Follicular Unit Extraction (FUE)

Follicular unit extraction (FUE) is a widely used surgical technique for hair restoration, yet hair follicle survival rates vary depending on surgical instrumentation, graft handling, and perioperative care. The purpose of this clinical trial is to evaluate whether an evidence-based, integrated perioperative protocol maximizes hair follicle graft survival compared with standard departmental practice in male patients undergoing FUE for androgenetic alopecia or localized scarring alopecia. Participants will be randomly assigned to one of two groups: * Integrated Protocol Group: Patients receive FUE surgery guided by a standardized workflow featuring algorithmic punch selection (0.8-1.0 mm), pre-set extraction depth and angulation, chilled holding solutions maintained at 4 °C, strict graft out-of-body time limits (target ≤2-4 hours), and standardized recipient site implantation. * Standard FUE Practice Group: Patients receive FUE surgery according to routine departmental practice, where punch selection, harvesting parameters, and graft handling follow the operating surgeon's standard routine. Follicle survival and hair density will be tracked using digital trichoscopy in pre-marked 1×1 cm reference scalp areas over a 12-month follow-up period. Investigators will also assess intraoperative follicular transection rates, procedural complications, and patient satisfaction between the two groups.

Safety, Pharmacokinetics and Efficacy of PP405 in Adults With AGA

The study is a two part study, designed to validate safety results from the Phase 1 PP405-001 trial while also characterizing longer term safety and PK. Part 1 of the trial is the randomized controlled portion that will focus on safety and PK following 28 days of blinded treatment administration with either PP405 or vehicle control. Part 2 of the trial is an open-label extension that will validate the results of Part 1 with 3 months of treatment administration.

Evaluation of Efficacy and Safety of Oral Minoxidil 1 mg in Female Androgenetic Alopecia

The goal of this clinical trial is to learn about oral minoxidil 1mg in the treatment of women with androgenetic alopecia, a type of hormone-imbalanced hair loss. The main questions to answer are to know about that minoxidil 1mg is as effective as minoxidil 2% topical solution (comparator product) and is more effective than placebo; and to ensure treatment with oral minoxidil is safe. Participants will be assigned randomly to receive one of the following treatment combinations: * the test product (oral minoxidil 1 mg, once/day) and the vehicle solution (vehicle means it looks like the comparator product, but it does not contain an active ingredient, 2 times/day), or * the placebo tablet (placebo means it looks like the test product, but it does not contain an active ingredient, once/day) and the comparator product (2% minoxidil solution, 2 times/day), or * the placebo tablet (once/day) and the vehicle solution (2 times/day). The clinical trial will take up to 36 weeks. During this time, patients will come to the clinical trial centre for 5 times for examinations and will be called by phone twice. At the visits, the following examinations will be performed: photos of the hair will be taken to determine hair density, assessment of changes in scalp hair growth, measurement of blood pressure, pulse, and body temperature, a physical examination, blood withdrawal to determine any abnormalities in the blood, urine sampling and analysis, performance of ECG, and evaluation of hypertrichosis (i.e., excessive hair growth over the body). Furthermore, patients will be asked daily whether they had experienced any side effects or took any new medications (or changed the dose of a known medication) or underwent any medical procedure. Also, women of childbearing potential must undergo pregnancy tests in blood and urine.

Topical Rifamycin SV for Wound Healing After Sapphire FUE Hair Transplantation

This prospective, parallel-group controlled clinical study evaluated whether a single topical rifamycin SV protocol added to standardized care after sapphire follicular unit extraction (FUE) was associated with earlier recorded wound healing. One hundred candidates were assessed, and 70 men were individually allocated 1:1 using MedCalc. Five participants were excluded after allocation but before surgery and before receiving the assigned intervention because final preoperative serological testing met prespecified exclusion criteria. The analyzed sample comprised 34 participants in the rifamycin SV group and 31 in the control group. Healing was assessed through postoperative Day 14 using scheduled clinical review and serial photographs. Infection and hypersensitivity were monitored as safety outcomes.

Androgenetic alopecia (AGA) is a common form of hair loss characterized by progressive hair follicle miniaturization. This prospective randomized comparative study evaluates the efficacy and safety of intradermal exosome injections compared with 5% topical minoxidil in patients with AGA. Forty patients were randomly assigned to receive either intradermal exosome injections or topical minoxidil for three months, with clinical, trichoscopic, patient-reported, and safety outcomes assessed at baseline, after treatment, and at 3-month follow-up.

Safety and Efficacy of VDPHL01 in Females With Androgenetic Alopecia (AGA)

This study will evaluate the safety and efficacy of VDPHL01 in female subjects with Androgenetic Alopecia (AGA). AGA is a genetic disorder caused by an excessive (too much) hair follicle response to androgens (hormones) that causes hair loss. VDPHL01 is an investigational oral drug to treat AGA. This multi-center, double blind, study will last about 13 months and includes 11 study visits (screening, baseline (day 1), week 2, month 1, month 2, month 4, month 6, month 8, month 10, month 12, month 13).

XVIE to Treat Androgenetic Alopecia (AGA)

This study tests whether XVIE, an investigational injectable product made from processed human amniotic fluid, is safe and may help regrow hair in adults with androgenetic alopecia (common pattern hair loss). XVIE contains growth factors and extracellular vesicles that may stimulate hair follicle activity. Thirty participants will be randomly assigned to receive either XVIE or a saline placebo injected into the scalp in two treatment sessions, 90 days apart. Neither participants nor study staff will know which treatment is being given. Participants will be followed for 6 months. The main goal is to evaluate safety. A secondary goal is to assess whether hair count, density, or coverage improves.

A Study on the Efficacy and Safety of Microneedling for Male Androgenetic Alopecia

Androgenetic alopecia (AGA) is the most prevalent hair-loss disorder in clinical practice. With a high incidence rate, it not only severely impairs patients' appearance and quality of life, but may also trigger varying degrees of depression and compromise mental health, highlighting the critical importance of standardized management for AGA. Current therapeutic options for AGA include oral finasteride, topical minoxidil, physical therapies and others. Nevertheless, safety concerns over oral medications remain prominent. Finasteride, a first-line agent, is associated with adverse reactions such as decreased libido, erectile dysfunction and reduced ejaculate volume, which limits patient acceptance. In recent years, microneedling for AGA has attracted attention, clinical adoption and recognition among dermatologists, demonstrating favorable safety profiles and promising therapeutic outcomes in real-world clinical practice. Minoxidil is an effective hair-growth-promoting drug. Topical 2% or 5% minoxidil exhibits satisfactory efficacy and safety for AGA and is frequently combined with other interventions to enhance treatment benefits. Microneedling combined with topical minoxidil represents a commonly-used regimen for AGA in clinical settings. However, substantial heterogeneity exists regarding microneedling parameters including needle depth, treatment frequency and total treatment duration across medical institutions and clinical studies. Needle depth is closely correlated with patient perception, therapeutic efficacy and adverse events such as bleeding; treatment frequency is strongly linked to patient compliance and clinical outcomes. Despite the widespread clinical use of microneedling, standardized treatment protocols are still lacking, which greatly undermines the standardization, treatment efficacy and patient compliance of physical therapy for androgenetic alopecia. This study plans to enroll 190 male patients with AGA. Participants will be stratified into different groups according to microneedling depth and treatment frequency, and receive standardized intervention for 24 weeks. The primary objective is to explore the optimal microneedling regimen (including needle depth and treatment frequency). We will also evaluate how disease course, hair-loss classification and severity grading influence therapeutic efficacy and safety among AGA patients. Findings from this trial will provide evidence-based references for dermatologists to deliver precise and individualized AGA care, support the development of clinical guidelines, and facilitate standardized clinical implementation of this combination therapy.

Comparing Standard Platelet-Rich Plasma and Light-Enhanced Platelet-Rich Plasma for Treating Hair Loss in Androgenetic Alopecia: A Randomized Controlled Trial

The goal of this clinical trial is to compare 3 different types of PRP in androgenetic alopecia patients. The main questions it aims to answer: Does Redlight enhanced, Blue light enhanced, or traditional PRP result in higher hair density and health? Does Redlight enhanced, Blue light enhanced, or traditional PRP result in other improved hair metrics. Participants will consent to a PRP treatment but will be blinded to the type. They will then be asked to return for Tricholab analysis at set post-operative timepoints to record changes in hair metrics (Baseline, 1 month, 3 months, 6 months, 9 months, 12 months).

Study of EPI-001 in Patients With Androgenetic Alopecia

This is a Phase I/IIa clinical study to evaluate the safety, tolerability, and preliminary efficacy of EPI-001 in patients with androgenetic alopecia.

Clinical response will be assessed using standardized trichoscopic parameters.

Phase 3 Study to Evaluate the Efficacy and Safety of Oral Minoxidil (N1087) in Men With Androgenetic Alopecia.

This study is a Phase 3 clinical trial designed to evaluate the efficacy and safety of N1087 compared with placebo in adult men with androgenetic alopecia (male pattern hair loss). The study will include male participants aged 18 to 60 years who have a clinical diagnosis of androgenetic alopecia classified as stages 3V, 4, or 5 on the Norwood-Hamilton scale. Participants will be randomly assigned, in a 2:1 ratio, to receive either N1087 or placebo. Neither the participants nor the study team will know which treatment each participant receives. The study treatment will be taken orally once daily for a total of 24 weeks. During the first 8 weeks, the dose will be gradually increased (titration period) up to a maximum tolerated dose, not exceeding 5 mg. Participants will then continue treatment at the maximum tolerated dose for the remaining 16 weeks. The main purpose of the study is to assess whether oral minoxidil improves hair growth. The primary outcome measure is the change from baseline in the density of non-vellus hairs in a defined target area of the scalp (vertex) after 24 weeks of treatment, measured using digital phototrichogram analysis. Secondary objectives include evaluating changes in hair density at earlier time points, hair thickness, the proportion of terminal hairs, clinical improvement assessed by the investigator, quality of life related to hair loss, and participant satisfaction with treatment. The safety and tolerability of oral minoxidil will also be evaluated by monitoring adverse events, vital signs, and events of special interest throughout the study. An independent Data and Safety Monitoring Committee will oversee participant safety during the trial. This is a multicenter study conducted in Brazil, with approximately 372 participants expected to be enrolled.
