Why Men Lose Hair
Male pattern baldness, or androgenetic alopecia, affects over 50% of men by age 40. It’s primarily caused by dihydrotestosterone (DHT), a testosterone byproduct that binds to hair follicles, shortening their growth cycle. Genetics and aging amplify this process, leading to progressive thinning.
Best Hair Regrowth Treatments in 2025
1. Finasteride (1mg daily): Reduces scalp DHT levels by over 60%, slowing follicle miniaturization. Long-term use leads to visible regrowth in 80% of users.
2. Topical Minoxidil (5%): Extends the anagen phase and increases blood flow to follicles. Foam and liquid forms remain first-line therapies for men.
3. Combination Therapy: The most effective approach. Studies published in 2024 show that combining finasteride and minoxidil yields 45% more regrowth than either alone.
Emerging Treatments
New therapies such as microneedling and exosome therapy have shown promising results. These stimulate stem cells and promote regeneration in dormant follicles.
Lifestyle Factors
Nutrition, stress, and sleep quality play crucial roles. Zinc, iron, and vitamin D deficiencies can worsen shedding. Stress management and exercise lower cortisol, preserving the growth cycle.
Expert Advice
“Consistency is key,” emphasizes Dr. Jonathan Reyes. “Most men quit early. Visible regrowth typically appears after 4–6 months.” Always consult a dermatologist before starting or combining treatments.
