Hair Loss Treatment for Men: What Actually Works?

Male-pattern hair loss (androgenetic alopecia) is the most common cause of hair loss in men, affecting approximately 50% of men by age 50. It is genetically driven and progressive, but early treatment can slow or reverse it. Health Canada-approved treatments include minoxidil (Rogaine) - a topical solution (2% or 5%) applied to the scalp twice daily. It is available over-the-counter. Results typically become visible after 3 to 6 months of consistent use. If stopped, hair loss resumes. Finasteride (Propecia) is an oral prescription medication taken daily. It blocks DHT, the hormone responsible for hair follicle miniaturization. Clinical studies show that finasteride maintained or increased hair count in 83% of men over 2 years. Side effects are uncommon but can include decreased libido (reported in 1 to 2% of users). Other options include low-level laser therapy (some evidence for mild to moderate hair loss), platelet-rich plasma (PRP) injections, and hair transplant surgery (for advanced loss - results are permanent). What does NOT work: biotin supplements (no evidence for pattern hair loss in non-deficient individuals), most \"hair growth\" shampoos, and unregulated supplements. Consult a physician to discuss which treatment is appropriate for you. *This article is for informational purposes only.*
