Androgenetic alopecia causes progressive thinning as follicles miniaturize under DHT. First-line treatments are topical minoxidil and oral finasteride, both requiring ongoing use. Hair transplantation (FUE/FUT) provides a permanent option when donor hair exists. Adjuncts such as PRP and LLLT have mixed evidence. Discuss benefits and risks with a clinician.

What is male pattern baldness?

Male pattern baldness (androgenetic alopecia) is the most common form of hair loss in men. Hair grows in cycles (anagen/growth phase typically 2-6 years, then a shedding phase), and at any moment most scalp hairs are actively growing. In genetically predisposed men, hair follicles gradually shrink (miniaturize) under the influence of dihydrotestosterone (DHT). Over time this produces thinner, shorter hairs and eventually no visible hair from those follicles.

Typical pattern and symptoms

The usual pattern is a receding hairline at the temples and thinning on the crown, which can progress into a horseshoe-shaped remaining fringe of hair. Any sudden, patchy, or widespread hair loss that doesn't follow this pattern should prompt evaluation by a clinician to rule out other causes.

Medical and non-medical treatment options

Deciding whether to treat depends on personal comfort and goals. Non-surgical options include camouflage (hair fibers, concealers, wigs) and hairstyles that minimize contrast. Avoid surgical suturing of hairpieces; it can cause scarring and infection. Synthetic hair implants have been linked to high complication rates and are not recommended - check current FDA guidance if considering this approach.

Topical minoxidil

Minoxidil (over-the-counter) is applied to the scalp. It can slow hair loss and produce regrowth in some men. Benefits require continued use; hair loss usually resumes if treatment stops.

Oral finasteride (and other 5-alpha-reductase inhibitors)

Finasteride (prescription) reduces conversion of testosterone to DHT and can halt progression and sometimes regrow hair. It is generally more effective than minoxidil for many men, but benefits reverse after stopping treatment. Some users experience sexual side effects (reduced libido, erectile issues) or mood changes; discuss risks with a clinician. Topical finasteride formulations and oral dutasteride are used in some practices and studies, but regulatory approval and long-term safety profiles vary - verify local availability and guidance. 1

Procedures: transplants, PRP, lasers

Modern hair transplants use follicular unit extraction (FUE) or follicular unit transplantation (FUT). These move healthy follicles from donor areas to thinning zones; results are generally permanent when done by experienced surgeons. Robotic assistance and improved microsurgery have refined outcomes.

Platelet-rich plasma (PRP) injections and low-level laser therapy (LLLT) are adjunctive treatments some men use. Evidence quality varies; they may help when combined with proven drugs but are not universally effective on their own. 2

Practical takeaways

  • Male pattern baldness is driven by genes and DHT; follicles miniaturize over years.
  • Minoxidil and finasteride are first-line medical treatments; both must be used continuously to maintain benefits.
  • Hair transplantation offers a permanent structural solution when donor hair is adequate.
  • Discuss side effects and realistic expectations with a dermatologist or hair restoration specialist.
If you're concerned about hair loss, get a medical evaluation to confirm the diagnosis and review options tailored to your goals.
  1. Confirm prevalence statistics by age (e.g., percent of men affected at ages 30 and 50)
  2. Verify current FDA guidance or regulatory status on synthetic hair implants and historical bans or advisories
  3. Check regulatory approval and availability of topical finasteride and oral dutasteride use for male pattern baldness in the target jurisdiction
  4. Review recent high-quality evidence summaries on PRP and low-level laser therapy efficacy for androgenetic alopecia

FAQs about Pattern Baldness

Will my hair return to exactly how it was before if I start treatment?
Not usually. Medications like minoxidil and finasteride can slow loss and restore some hair, but they rarely restore a full original hairline. Continued use is necessary to maintain gains.
How long before I see results from minoxidil or finasteride?
Expect at least 3-6 months of consistent use to see changes, and up to a year for clearer results. Stopping treatment typically leads to loss of any gained hair within months.
Are hair transplants permanent?
Transplanted follicles taken from genetically resistant donor areas usually continue to grow permanently. However, non-transplanted hair may keep thinning, and multiple sessions can be needed for density.
Are there serious risks with finasteride?
A minority of men report sexual side effects (reduced libido, erectile dysfunction) or mood changes. These commonly resolve after stopping the drug, but discuss potential risks with your doctor.
Do newer treatments like PRP or laser therapy work?
PRP and low-level laser therapy may help some men as adjuncts, but the quality of evidence is mixed. They are best used alongside proven medical treatments.
