📌 Patient Information Section: What Do Medical Treatments Entail?

Hair loss or a decrease in hair quality does not always necessitate surgical operations like hair transplantation. Medical treatments, applied in the early and middle stages of miniaturization (shrinking) when hair follicles have not yet completely lost their vitality, are the most fundamental methods for preserving hair and stopping hair loss.

  • In Which Cases Are They Applied?: They are preferred in the early stages of male-pattern (Androgenetic Alopecia) or female-pattern (FPHL) hair loss, in cases of telogen effluvium (widespread shedding), and to improve the quality of hair strands.
  • How Do They Work?: They increase capillary blood flow to the hair follicles, support follicle nourishment, and alleviate the negative pressure of hormones responsible for hair loss (e.g., DHT) on the follicles.
  • When Are Results Achieved?: Due to the slow biological nature of the hair cycle, the first noticeable improvements and reduction in hair loss with medical treatments are generally observed between 3 to 6 months.
Minoxidil, Finasteride, and Dutasteride Mechanisms of Action – Dr. Muhammet Özgehan

🩺 Clinical & Medical Guide for Physicians

  • Etiology and Pharmacological Approach: Targeting androgenic and vascular factors involved in hair follicle miniaturization. Supporting follicular cell proliferation.
  • Topical and Systemic Agents:
    • Minoxidil (2% and 5%): Topical and low-dose oral formulations that prolong the anagen phase and increase hair shaft diameter by enhancing vascular endothelial growth factor (VEGF) release.
    • 5-Alpha Reductase Inhibitors: Systemic agents (finasteride/dutasteride) that suppress the conversion of testosterone to dihydrotestosterone (DHT) in male-pattern hair loss.
Antiandrogen Treatment in Female-Pattern Hair Loss – Dr. Muhammet Özgehan

Figure 2: Antiandrogen agents such as spironolactone and cyproterone acetate in female-pattern hair loss, showing their pathways of follicular receptor blockade and hormonal regulation.

  • Antiandrogens (For Female Patients): Management of agents such as spironolactone, cyproterone acetate, or flutamide in female patients with signs of hyperandrogenism (acne, hirsutism, etc.) through androgen receptor blockade and ovarian/adrenal androgen suppression.
  • Clinical Follow-up and Combination Management: Optimization of single pharmacological agents according to the patient's etiological profile. Periodic monitoring of hair diameter and density measurements with digital trichoscopy. Additionally, expertise and treatment approaches can be reviewed for clinical and surgical evaluations.
