The Modern Man’s Guide to Hair Loss: Causes, Myths, and What Actually Works

Let’s take the drama out of this. Losing hair is something most men will face at some point—by 50, around half will notice thinning or a receding hairline. It’s common, it’s natural, and it’s not the end of looking or feeling good.

Quick version first

The most common cause of hair loss in men is male pattern baldness (also known as androgenetic alopecia). It’s largely genetic and linked to how your hair follicles respond to a hormone called DHT (dihydrotestosterone), a derivative of testosterone.

Over time, DHT causes certain hair follicles—especially at the temples and crown—to shrink, producing thinner, shorter hairs until they stop growing altogether.

Other causes worth checking

Not every case of hair loss is hormonal. Sometimes it’s:

• Stress or illness (temporary shedding known as telogen effluvium)
• Nutritional deficiencies (especially iron, vitamin D, or protein)
• Thyroid problems
• Medications (such as some antidepressants or blood pressure tablets)
• Autoimmune conditions (like alopecia areata)

That’s why a proper assessment matters—to work out what’s really going on before jumping into treatment.

Common myths (and the truth behind them)

Myth 1: Wearing hats causes baldness.

Nope. Hair loss happens at the follicle level, not from pressure or lack of “breathing.”

Myth 2: You inherit baldness from your mum’s side.

Genes from both parents play a role, not just one side of the family.

Myth 3: Cutting hair makes it grow back thicker.

It might look thicker for a week or two, but trimming doesn’t affect follicle strength or density.

Myth 4: Nothing works, just accept it.

Actually, some clinically approved treatments can slow or even reverse hair loss for certain men. But they must be prescribed and used correctly.

What actually works

There are two clinically proven medicines for male pattern hair loss in the UK:

• Topical minoxidil (available over the counter)
• Oral finasteride (prescription only)

Minoxidil helps by improving blood flow to the scalp and extending the hair growth phase. Finasteride works differently—it reduces the conversion of testosterone into DHT, helping protect hair follicles from shrinkage.

Neither is instant. You’ll usually need at least 3–6 months to see noticeable change, and results vary from person to person. Stopping treatment often leads to gradual hair loss returning.

Prescription medicines are only available after clinical assessment.

Beyond medication

Hair transplants, laser therapy, and platelet-rich plasma (PRP) injections exist, but they’re specialist procedures that come with cost, commitment, and variable evidence.

For many men, a tailored plan of approved treatment, a healthy scalp routine, and realistic expectations make the biggest difference.

What your clinician will check

A proper review usually includes:

• Medical history (including family pattern of hair loss)
• Lifestyle and stress levels
• Scalp examination
• Possible blood tests if other causes are suspected

Your clinician will then guide you through safe, evidence-based options—or advise if a treatment isn’t right for you.

The bottom line

Hair loss doesn’t define you. But if it’s bothering you, there are safe and sensible ways to address it.

Private care, minus the faff. A quick, confidential consultation can help you understand the cause and plan a treatment that fits.

If it’s not right for you, we’ll say so, and suggest what is.
