Thinning Hair in Men: Causes and Modern Treatments

Thinning Hair in Men: Causes and Modern Treatments

Thinning hair is a challenge many men face, and it’s something I’ve experienced personally—not just in my clients but in my own life. I’m Sergio Slavnov, owner of Avenue Man Hair Products and one of the well-known men’s hairstylists in New York City.

I started losing hair in the front when I was younger, and you can see it in my early photos before I had a hair transplant by top NYC surgeon Dr. Carlos Wesley and began using Finasteride. That combination made a big difference for me. My hair isn’t perfect, but I feel much more comfortable with it now than I did in my early twenties.

My son, George, had a similar experience, starting to lose hair at just eighteen. He had very little in the front, and it was tough for him. But after starting Finasteride, his hair completely transformed. By twenty-one, he had a full, thick pompadour—a big change from how he looked just a few years earlier. The difference in his hair fullness is striking.

Proven treatments like Finasteride and Minoxidil can make a real impact. Finasteride blocks DHT, the hormone responsible for shrinking hair follicles, while Minoxidil helps extend the growth phase of hair. Both are highly effective with consistent use over three to six months. Telehealth providers like Hims and Happy Head even offer convenient liquid versions, combining both treatments in sprays or droppers for targeted results.

For those who prefer a natural approach, supplements like Nutrafol can address key nutrient deficiencies like vitamin D, zinc, and biotin to promote hair health. And for men looking for more permanent results, hair transplant surgery can provide natural, lasting improvements when performed by a skilled surgeon.

As someone who’s been through the journey myself and seen the results in my son, I know how life-changing the right treatments can be. Whether you’re just noticing thinning hair or want a full transformation, there are effective solutions to help you feel more confident.

For those seeking a more natural approach, certain supplements may help slow or reverse thinning hair by addressing nutrient deficiencies. Key nutrients for hair growth include vitamin D (at least 10 000 i.u. a day), zinc, saw palmetto and biotin. Nutrafol is one supplement specifically formulated to support hair health. It contains an evidence-based blend of vitamins, minerals and botanicals.

Vitamin D plays a key role in hair health because hair follicles have vitamin D receptors, which are crucial for maintaining the growth cycle of hair. Here’s how it relates to healthy, beautiful hair:
 • Stimulates Hair Follicles: Vitamin D helps activate hair follicles, which can promote new growth and keep the hair in its growth phase longer. This is especially important for maintaining thick and healthy hair.
 • Prevents Hair Loss: A deficiency in vitamin D has been linked to hair thinning and alopecia (patchy hair loss). Ensuring adequate levels may reduce shedding and slow down thinning.
 • Supports Scalp Health: Vitamin D’s role in reducing inflammation can help maintain a healthy scalp environment, essential for strong, vibrant hair.
 • Nourishes Follicles: It aids in the production of keratin, a protein that forms the structure of your hair, making it stronger and less prone to breakage.
 • Boosts Overall Growth: Healthy levels of vitamin D promote the regeneration of damaged hair follicles, supporting fuller, more beautiful hair.

If you’re experiencing thinning or hair loss, vitamin D supplements or foods rich in it (like salmon, eggs, and fortified milk) can support hair health.

When medical treatments and supplements are not enough, hair transplant surgery offers a permanent solution. This involves taking hair follicles from thicker parts of the scalp and surgically implanting them into balding or thinning areas. While expensive, a skilled hair restoration surgeon can create very natural-looking results.

Lastly, using the right hair styling products makes a big difference in keeping thinning hair looking its best. Avenue Man's Argan Oil Volumizing Mousse helps create the appearance of thicker, fuller hair while nourishing the scalp with organic ingredients. Avenue Man's Thickening Hair Spray is another excellent option that adds volume and hold without damaging hair like many conventional hairsprays.

With the range of treatments now available, there are more solutions than ever for men struggling with hair loss. A multi-pronged approach that combines clinically-proven medications or supplements with volumizing hair products can help men regain thicker, healthier-looking hair and renewed self-confidence. As with any medical concern, men who are losing hair should talk to their doctor to determine the underlying causes and develop a personalized treatment plan.
