What Causes It, How to Recognise It and What You Can Do About It

Hair loss is something many men experience, but that doesn't make it any less frustrating.

For some, it starts with a slightly receding hairline. For others, the first noticeable sign is thinning around the crown or a gradual reduction in overall density.

Male pattern hair loss is the most common type of hair loss in men. It can develop at almost any age after puberty and tends to progress gradually over years or decades.

The good news is that understanding what is happening to your hair is the first step towards making informed decisions about your options.

In this guide, we'll explain what male pattern hair loss is, why it happens, how to recognise the early signs and the treatment options that may be considered.

What Is Male Pattern Hair Loss?

Male pattern hair loss is also known as androgenetic alopecia.

It is primarily influenced by genetics and hormones. A hormone called dihydrotestosterone (DHT) plays an important role in the process.

In genetically susceptible hair follicles, DHT contributes to a process called miniaturisation.

Over time, affected follicles can produce hairs that are:

• Finer
• Shorter
• Lighter
• Less visible

Eventually, some affected follicles may stop producing visible hair altogether.

This is why male pattern hair loss is usually a gradual process rather than hair suddenly falling out all at once.

What Does Male Pattern Hair Loss Look Like?

Male pattern hair loss doesn't look exactly the same in everyone.

Common early signs include:

A receding hairline

The hairline gradually moves backwards, often beginning around the temples.

Thinning at the crown

Hair density at the crown can gradually decrease, making more of the scalp visible.

Thinning across the top

Some men experience more general thinning across the front and top of the scalp rather than a clearly defined receding hairline.

Increasingly fine hairs

Sometimes the first sign isn't obvious hair loss at all. You may notice that individual hairs are becoming finer and less dense.

The hair at the sides and back of the scalp is typically less affected by male pattern hair loss.

Why Does Male Pattern Hair Loss Happen?

There isn't one single cause.

Genetics and hormones both play important roles.

Your genetic susceptibility determines how sensitive particular hair follicles are to DHT. This helps explain why some men experience significant hair loss while others retain a full head of hair throughout their lives.

It also explains why hair loss can vary significantly between family members.

Contrary to a common myth, your hair loss pattern isn't simply determined by your mother's side of the family. Genetic factors can come from both sides of the family.

The Role of DHT

DHT is produced when testosterone is converted by an enzyme called 5-alpha reductase.

For men who are genetically susceptible to male pattern hair loss, DHT can contribute to the miniaturisation of hair follicles.

This is one reason why treatments that affect the DHT pathway, such as finasteride, can play a role in managing male pattern hair loss.

Finasteride is a prescription medicine that reduces the conversion of testosterone into DHT and can slow hair loss and potentially support regrowth in some men.

Is Male Pattern Hair Loss Preventable?

There isn't currently a cure for male pattern hair loss.

However, treatments can help slow its progression and, depending on the individual and treatment, potentially improve hair growth.

The earlier you recognise progressive hair loss, the sooner you can seek professional advice about whether treatment is appropriate.

That doesn't mean everyone experiencing hair loss needs treatment.

The most important first step is understanding why you're losing your hair.

What Treatments Are Available?

There are several approaches that may be considered for male pattern hair loss.

Two of the most established treatments are minoxidil and finasteride.

Minoxidil

Minoxidil is a topical treatment that can help slow hair loss and stimulate hair growth.

5% minoxidil liquid or foam can be applied to areas of affected scalp. The British Association of Dermatologists notes that it may take at least six months, and potentially longer, before benefits become apparent.

Some people may also experience an initial increase in shedding during the early stages of treatment. This can be temporary.

Finasteride

Finasteride is an oral prescription treatment used for male pattern hair loss.

It reduces levels of DHT and may help slow hair loss and support regrowth.

The NHS notes that some improvement in hair loss may be seen after around three to six months, although individual responses vary.

Finasteride can cause side effects in some people, including sexual side effects and, less commonly, mood-related effects. It should only be taken following appropriate medical assessment and advice.

Can Minoxidil and Finasteride Be Used Together?

Because the two treatments work through different mechanisms, they may sometimes be used together as part of a treatment plan.

Minoxidil acts primarily as a topical hair-growth treatment, while finasteride works by reducing DHT.

Whether combining treatments is appropriate depends on the individual, their medical history and the assessment of a qualified healthcare professional.

More treatment isn't necessarily better for everyone.

The right approach is the one that is appropriate for the individual and can be used consistently and safely.

What About Tretinoin?

Tretinoin is a topical retinoid that has also been investigated in relation to hair loss and is sometimes included in compounded topical formulations.

Its use alongside minoxidil is an area of interest because tretinoin may influence skin and follicular biology and may affect the absorption of topical minoxidil.

However, evidence and clinical practice around compounded combinations can differ from the evidence for licensed treatments.

This is why treatment decisions should be made following an appropriate clinical assessment rather than simply combining ingredients yourself.

What About Hair Transplants?

Hair transplantation is another option for some people experiencing male pattern hair loss.

Unlike medication, a transplant involves surgically moving hair follicles from a donor area—typically the sides or back of the scalp—to areas affected by hair loss.

A hair transplant doesn't necessarily stop the underlying progression of male pattern hair loss.

For this reason, some people may discuss ongoing medical treatment alongside or following a transplant with their clinician.

Whether a transplant is appropriate depends on factors including the pattern and extent of hair loss, donor hair availability, age and individual expectations.

How Long Does Male Pattern Hair Loss Take to Progress?

There isn't a fixed timeline.

For some men, noticeable changes develop relatively slowly over many years.

For others, hair loss may become apparent earlier and progress more quickly.

The British Association of Dermatologists notes that male pattern hair loss generally progresses slowly, over several years to decades, although an earlier age of onset can be associated with quicker progression.

This is one reason why comparing your hair loss timeline directly with someone else's isn't particularly useful.

What If You're Not Sure Whether You Have Male Pattern Hair Loss?

Not all hair loss is male pattern hair loss.

Other causes can include:

• Temporary shedding
• Stress-related hair loss
• Nutritional deficiencies
• Certain medical conditions
• Medication
• Scalp disorders
• Autoimmune conditions

If your hair loss is sudden, patchy, accompanied by scalp inflammation or otherwise unusual, it's particularly important to seek professional medical advice rather than assuming it's male pattern hair loss.

A healthcare professional can assess the pattern and history of your hair loss and determine whether further investigation is appropriate.

Does Male Pattern Hair Loss Affect Your Health?

Male pattern hair loss itself isn't generally dangerous.

However, hair can have a significant effect on confidence, self-esteem and body image.

If your hair loss is affecting your wellbeing, it's completely reasonable to discuss it with a healthcare professional.

Treatment isn't only about appearance. Feeling comfortable and confident in yourself matters too.

What Should You Do If You've Started Losing Your Hair?

If you've noticed early signs of hair loss, don't panic.

A sensible approach is:

1. Understand the pattern

Look at where the thinning is occurring and whether it appears gradual.

2. Consider your family history

Male pattern hair loss has a strong genetic component.

3. Take consistent photographs

Photographs taken under similar lighting and from similar angles can help you monitor changes over time.

4. Learn about your options

Understand how treatments such as minoxidil and finasteride work, including their potential benefits and risks.

5. Seek professional advice

A qualified healthcare professional can help determine whether treatment is appropriate for you.

Frequently Asked Questions

Is male pattern hair loss genetic?

Yes. Genetics play a major role, alongside hormonal factors. Genetic susceptibility can be inherited from either side of the family.

Can male pattern hair loss be cured?

There is currently no cure for male pattern hair loss. However, treatments can help manage the condition and may slow progression or support hair growth.

Does wearing a hat cause hair loss?

No. Wearing a normal hat does not cause male pattern hair loss.

Does cutting your hair make it grow back thicker?

No. Cutting hair doesn't change the thickness of the hair follicle or alter the underlying growth cycle. It can make hair appear temporarily thicker because the cut ends are blunt.

Can stress cause hair loss?

Stress can contribute to certain types of temporary hair shedding, but this is different from male pattern hair loss. If you're experiencing sudden or significant shedding, seek professional advice.

Should I start treatment as soon as I notice thinning?

Not necessarily. The appropriate treatment depends on the cause and pattern of your hair loss. However, recognising progressive hair loss early gives you the opportunity to seek advice sooner.

Do hair loss treatments work permanently?

No. Treatments such as minoxidil and finasteride generally need to be continued to maintain their benefits. Hair loss can resume after treatment is discontinued.

Key Takeaways

Male pattern hair loss is extremely common and is influenced by both genetics and hormones.

DHT plays an important role in the miniaturisation of susceptible hair follicles.

There is no current cure, but established treatments can help manage the condition.

Minoxidil can help stimulate hair growth and slow progression.

Finasteride reduces DHT and can help slow hair loss and potentially support regrowth.

Other approaches, including hair transplantation and certain compounded topical formulations, may be appropriate in selected circumstances.

Most importantly, treatment should be based on an appropriate assessment rather than internet claims or one-size-fits-all advice.
