Male Pattern Baldness (Androgenetic Alopecia)

Male pattern baldness — also known as androgenetic alopecia in men — is the most common form of hair loss in males. It typically begins with thinning at the temples and/or crown and progresses gradually over time. While some men notice changes in their late teens or 20s, most experience visible thinning from their 30s onward.

The pattern and speed of hair loss vary from person to person. Some men lose only a small amount of hair, while others may develop more extensive thinning across the top of the scalp. The sides and back usually remain relatively stable because those follicles are less sensitive to hormones.

Hair loss can affect self-confidence, body image, and overall wellbeing. The good news: although there’s no permanent cure, a number of evidence-based strategies can help slow progression, support regrowth, and maintain healthier, fuller-looking hair.

What Causes Male Pattern Baldness?

Male pattern baldness is largely a genetic and hormonal condition. If you inherit a predisposition, your hair follicles are more sensitive to androgens — particularly DHT (dihydrotestosterone), a derivative of testosterone.

In genetically susceptible follicles, DHT binds to receptors in the follicle and gradually triggers miniaturisation. As this happens:

• Hair shafts become progressively finer and shorter
• The growth (anagen) phase of the hair cycle becomes shorter
• More follicles shift into resting or shedding phases
• Eventually, some follicles stop producing visible hair altogether

Despite popular myths, men with male pattern baldness do not necessarily have higher overall testosterone levels. The issue is that their follicles are more sensitive to DHT, not that they always produce more of it.

Other Contributing Factors

Genetics and DHT are central, but other factors can influence how quickly hair loss progresses:

• Family history of androgenetic alopecia on either side
• Age – the likelihood and extent of hair loss increase with age
• Hormonal changes or imbalances
• Stress and lifestyle, which can aggravate shedding
• Underlying health issues, such as nutritional deficiencies or thyroid disorders

Addressing general health, nutrition, and stress will not “cure” male pattern baldness, but it can help your hair respond better to treatments and look as strong as possible.

Common Signs and Progression

Male pattern baldness follows recognisable patterns, often described by the Norwood scale. Early detection gives you the best chance of slowing progression and preserving density.

1) Receding Hairline

One of the classic early signs is a receding hairline at the temples, creating an “M” shape. This may slowly advance back over years and can eventually join thinning at the crown.

2) Thinning or Bald Patch at the Crown

Many men first notice a thin area or bald patch on the vertex (crown), especially in photos or under bright lighting. Over time, this area can expand in diameter.

3) Diffuse Thinning on Top

Some men experience more diffuse thinning across the top of the scalp rather than a sharply defined patch. Hair may look flatter, finer, and less dense, while the sides and back remain relatively strong.

4) The Norwood Stages of Male Pattern Baldness

The Norwood scale is commonly used to describe progression:

• Norwood 1–2: Minimal recession; early templar thinning or slightly mature hairline
• Norwood 3: Clear recession at the temples; early balding pattern
• Norwood 3 Vertex: Recession with a noticeable bald spot on the crown
• Norwood 4–5: Larger crown thinning, deeper recession; areas may begin to join
• Norwood 6–7: Extensive loss on top; only a horseshoe-shaped band of hair remains on the sides and back

Knowing your Norwood stage can help guide expectations and decide which treatments are most practical, including whether hair transplant surgery is a realistic option.

When Hair Loss Might Not Be “Just” Male Pattern Baldness

While androgenetic alopecia is the most common cause, sometimes hair loss is driven or worsened by other conditions. You should seek professional advice if:

• Thinning is sudden or patchy rather than gradual
• You notice redness, itching, pain, or scaling of the scalp
• Hair is coming out in clumps or leaving smooth, bald patches

Conditions like telogen effluvium, alopecia areata, scalp psoriasis, infections, or scarring alopecias may require different management.

How Is Male Pattern Baldness Diagnosed?

In many cases, an experienced GP, dermatologist, or trichologist can diagnose male pattern baldness based on:

• Your medical and family history
• The pattern and timing of thinning
• A physical examination of the scalp

If the pattern is atypical or hair loss is very rapid, they may run blood tests to rule out issues like thyroid disease, iron deficiency, or other underlying conditions that can contribute to shedding.

Getting a clear diagnosis helps set realistic goals and choose the most appropriate combination of treatments.

How to Treat Male Pattern Baldness

While male pattern baldness cannot be permanently cured, a combination of approaches can help slow loss, support regrowth, and maintain scalp and hair health. Results vary and consistency is critical — most plans are long-term rather than quick fixes.

1) Minoxidil (Topical)

Minoxidil is one of the most widely used treatments for male pattern baldness. Applied to the scalp, it helps:

• Extend the growth (anagen) phase
• Increase blood flow around follicles
• Support thicker, stronger hairs in miniaturising follicles

It is available over the counter in foam or solution forms. Most men need to use minoxidil for at least 3–6 months before judging results, and benefits only continue while treatment is maintained.

Learn more about alternatives and topical routines that can complement or substitute minoxidil in some cases.

2) Finasteride (Oral; Men)

Finasteride is a prescription oral medication for men that works by reducing levels of DHT. By lowering DHT at the follicle, it:

• Helps slow or halt further miniaturisation
• Can maintain and sometimes thicken existing hair
• Is often used in combination with topical treatments

As with any medication, there are potential side effects, and it should only be used under medical supervision. Some men look for non-drug alternatives or adjuncts depending on their risk/benefit preferences.

Learn more about alternatives and supporting options.

3) Ketoconazole Shampoos

Ketoconazole-based shampoos are often included in hair loss routines to support scalp health. They may:

• Help control dandruff and inflammation
• Improve the scalp environment for follicles
• Offer mild anti-androgen benefits when used consistently

4) Serums & Topical Support

Specialised serums and topicals — such as KGF (Keratinocyte Growth Factor) based products — can support the scalp and complement other treatments by:

• Nourishing the scalp and follicles
• Supporting thicker, stronger-looking hair
• Helping men stick to a consistent routine

Learn more about serum options.

5) Low-Level Laser Therapy (LLLT)

Low-Level Laser Therapy involves using laser caps, helmets, or combs that emit specific wavelengths of light to the scalp. This may:

• Improve cellular energy (ATP) in follicles
• Increase blood flow
• Support thicker regrowth when used regularly

LLLT is often used alongside minoxidil, finasteride, and nutritional support for a multi-targeted approach.

6) Microneedling

Microneedling uses fine needles to create controlled micro-injuries in the scalp. This can:

• Stimulate wound-healing pathways that benefit hair
• Improve penetration of topical treatments
• Be performed at home or in a clinic (professional guidance recommended)

7) Hair Transplant Surgery

For suitable candidates, hair transplant surgery can redistribute follicles from permanent donor areas at the back and sides to thinning regions on top. It is generally best for:

• Men with stabilised hair loss
• Adequate donor density
• Realistic expectations about coverage and density

Even after transplant, ongoing medical or supportive therapy is usually recommended to protect non-transplanted hair.

8) Lifestyle & Nutrition

While lifestyle alone won’t stop male pattern baldness, it provides a foundation for better hair health and can support other treatments:

• Balanced diet with adequate protein, healthy fats, vitamins, and minerals
• Manage stress through sleep, exercise, and relaxation techniques
• Limit harsh styling and tight hairstyles that may cause breakage or traction
• Maintain scalp hygiene and avoid product build-up

Many men add targeted hair supplements to cover nutritional gaps and support normal hair growth. This is where HR23+ fits in.

Drug-Free Support: HR23+

For men in the early to mid stages of male pattern baldness, a comprehensive routine often includes nutritional support alongside topical and/or medical treatments. HR23+ is a premium, drug-free supplement designed to help:

• Reduce excessive shedding
• Support normal hair growth cycles
• Promote stronger, fuller-looking hair
• Complement treatments like minoxidil, finasteride alternatives, and serums

Many consistent users report visible improvements in hair thickness and overall quality within 3–6 months. As with any supplement, results vary, and it works best as part of a broader hair care strategy.

When to Seek Professional Advice

It’s a good idea to speak with a GP, dermatologist, or trichologist if:

• Your hair loss is rapid or started suddenly
• You notice patchy hair loss or smooth bald patches
• The scalp is itchy, painful, red, or scaly
• You have other health symptoms (fatigue, weight changes, etc.) that may suggest an underlying condition

Early assessment helps rule out other causes, tailor a treatment plan, and set realistic expectations about regrowth and long-term maintenance.

Frequently Asked Questions About Male Pattern Baldness

Is male pattern baldness reversible?

Male pattern baldness is a progressive condition driven by genetics and androgen sensitivity. It cannot be permanently cured, but in many men it can be slowed and partially reversed with consistent, long-term treatment. The earlier you act, the more hair you are likely to preserve.

When should I start treating hair loss?

Generally, the best time to start is as soon as you notice consistent thinning, recession, or shedding that does not improve. Waiting until hair loss is advanced limits how much density can realistically be restored.

Do I inherit baldness from my mother’s side?

The genetics of androgenetic alopecia are complex and can come from both sides of the family. Having close relatives (father, brothers, uncles, grandfathers) with significant hair loss increases your risk, but does not guarantee you will follow the exact same pattern.

Do hats or hair products cause hair loss?

No. Wearing hats, using gel, or shampooing regularly does not cause male pattern baldness. However, harsh styling practices, very tight hairstyles, or chemical damage can make existing thinning look worse and may cause breakage.

How long should I stay on treatment?

Most male hair loss treatments need to be viewed as long-term commitments. If you stop using them, miniaturisation usually resumes, and hair may gradually return to its pre-treatment pattern over time.

Conclusion

Male pattern baldness is extremely common, but that doesn’t mean you have to accept rapid or uncontrolled thinning. Understanding the causes, recognising early signs, and acting promptly can make a real difference in how your hair looks and feels over the long term.

A smart approach typically combines:

• Evidence-based topical and/or oral treatments
• Supportive scalp care and styling habits
• Targeted nutritional support, such as HR23+
• Professional assessment when needed

With a consistent routine and realistic expectations, many men are able to stabilise loss, improve density, and feel more confident in their hair.
