Male Pattern Hair Loss: Treatment Options, Minoxidil Application and What to Expect
By Dr Lim Tzyy Huei | Consultant Dermatologist, Pantai Hospital Batu Pahat, Johor, Malaysia
Hair thinning and a receding hairline are common concerns among men. Some experience these changes as early as their twenties, while others develop gradual hair loss later in life.
The most common cause is male pattern hair loss, medically known as androgenetic alopecia.
Although this condition is progressive, early diagnosis and appropriate treatment can help slow further hair loss, preserve existing hair and, in some cases, improve hair density.
Successful treatment requires patience, consistency and realistic expectations.
What Causes Male Pattern Hair Loss?
Male pattern hair loss develops due to genetic predisposition and increased sensitivity of certain hair follicles to dihydrotestosterone (DHT), a hormone derived from testosterone.
Over time, DHT causes susceptible hair follicles to gradually shrink, a process known as follicular miniaturisation. As a result, hair strands become progressively finer, shorter and less visible.
Common signs include:
Receding hairline, particularly around the temples
Gradual thinning over the crown
Reduced hair density on the top of the scalp
Increasing visibility of the scalp
Male pattern hair loss can be inherited from either side of the family.

Hair thinning also affects women, although the pattern often differs. While men commonly experience a receding hairline and crown thinning, women typically notice a widening central hair parting and reduced hair density.

What Are the Treatment Options?
Treatment depends on the severity of hair loss, age, medical history and individual preferences.
The main goals are to slow further hair thinning, preserve existing hair and encourage regrowth where possible.
1. Topical Minoxidil – Stimulating Hair Growth
Topical minoxidil is one of the most established treatments for male pattern hair loss.
It is available as a solution or foam, with 5% minoxidil commonly recommended for men.
Minoxidil helps prolong the hair growth phase and improve the thickness of miniaturised hair strands.
Potential benefits include:
Slowing further hair thinning
Improving hair thickness and density
Encouraging regrowth in partially miniaturised follicles
Maintaining existing hair
For men, 5% minoxidil solution is generally applied twice daily, unless otherwise advised by a dermatologist.
How to Apply Topical Minoxidil Solution Correctly
Proper application helps ensure the medication reaches the affected scalp rather than remaining on the hair strands.
Step 1: Apply to a dry scalp
Ensure the scalp is dry before application. Washing your hair before every application is unnecessary.
Step 2: Part your hair
Separate the hair to expose the thinning areas, particularly over the crown and top of the scalp.
Step 3: Apply the recommended amount
For most 5% minoxidil solutions, apply 1 mL per application, twice daily.
Use the supplied dropper or spray applicator. The number of sprays required to deliver 1 mL varies between products.
Step 4: Spread gently
Apply the solution directly onto the affected scalp and spread gently using your fingertips.
Avoid applying it mainly onto the hair strands. Vigorous massage is unnecessary.
Step 5: Allow it to dry
Leave the solution on the scalp and allow it to dry naturally.
Avoid washing your hair or swimming for approximately four hours after application.
Step 6: Wash your hands
Wash your hands thoroughly after application to prevent accidental transfer to the face, eyes or other areas.
Important reminders:
Do not exceed the recommended amount, as applying more does not improve results.
Avoid applying minoxidil to irritated, inflamed or broken scalp skin.
Allow the solution to dry completely before going to bed.
Keep minoxidil away from children and pets, particularly cats.
Apply consistently for the best results.
Some patients may experience scalp itching, dryness or irritation. Alternative formulations, such as minoxidil foam, may be better tolerated.
2. Oral Finasteride – Reducing DHT
Finasteride is a prescription medication that reduces the conversion of testosterone into DHT.
By lowering DHT levels, finasteride helps slow hair follicle miniaturisation, maintain existing hair and potentially improve hair density.
The commonly prescribed dosage for male pattern hair loss is finasteride 1 mg once daily.
Possible side effects include reduced libido, erectile or ejaculation difficulties and mood-related symptoms.
These potential risks should be discussed with a doctor before starting treatment.
Because finasteride and minoxidil work through different mechanisms, they may be prescribed together for suitable patients.
3. Other Treatment Options
Depending on individual needs and response to treatment, a dermatologist may consider additional options.
Low-Dose Oral Minoxidil
Low-dose oral minoxidil may be considered when topical treatment is unsuitable, poorly tolerated or difficult to maintain.
Its use for hair loss is off-label and requires medical supervision because of possible side effects, including excess body hair growth, ankle swelling, dizziness, palpitations and changes in blood pressure.
Dutasteride
Dutasteride reduces DHT levels more extensively than finasteride.
It may be considered in selected patients, particularly those with an inadequate response to conventional treatment. Its use for hair loss is off-label in many countries.
Platelet-Rich Plasma (PRP) Therapy
PRP involves injecting concentrated platelets obtained from the patient's own blood into the scalp.
Some patients may experience improvement in hair density, although results vary and repeated treatment sessions may be necessary.
Low-Level Laser Therapy (LLLT)
Specialised light-based devices, such as laser caps or combs, may provide modest improvements in hair density when used consistently.
Hair Transplantation
Hair transplantation may be suitable for selected patients with established hair loss and adequate donor hair.
However, medical treatment may still be required to maintain the surrounding non-transplanted hair.
How Long Does Hair Loss Treatment Take to Work?
Hair regrowth is a gradual process. Most patients should not expect significant improvement within the first few weeks.
Treatment duration | What to expect |
First 1–2 months | Temporary increased shedding may occur, particularly after starting minoxidil. |
3–4 months | Hair shedding may begin to stabilise, with early signs of regrowth in some patients. |
6 months | Improvements in hair thickness or density may become more noticeable. |
6–12 months | A more meaningful assessment of treatment effectiveness can be made. |
Beyond 12 months | Continued treatment helps maintain the improvements achieved. |
These timelines are approximate. Treatment responses vary, and some patients may experience limited regrowth despite consistent use.
Why Does Hair Shedding Sometimes Increase After Starting Minoxidil?
Some patients notice increased hair shedding during the first few weeks after starting minoxidil.
This happens because minoxidil influences the hair growth cycle, allowing older resting hairs to shed as follicles transition towards a new growth phase.
Temporary early shedding does not necessarily mean the treatment is failing.
It usually settles with continued treatment. However, excessive or persistent shedding should be assessed to exclude other causes of hair loss.
Do I Need to Continue Treatment Long-Term?
Male pattern hair loss is a chronic, progressive condition.
Although treatments such as minoxidil and finasteride can help control hair loss, they do not permanently eliminate the underlying genetic and hormonal tendency.
Therefore, long-term maintenance treatment is usually necessary.
If treatment is discontinued, the improvements achieved may gradually be lost over the following months.
It is also important to understand that successful treatment does not always mean restoring a completely full head of hair.
For many patients, preventing further thinning and maintaining existing hair density are already meaningful treatment outcomes.
Can Hair Grow Back Completely?
The degree of regrowth depends on several factors:
How early treatment is started
Severity and duration of hair loss
Degree of hair follicle miniaturisation
Consistency of treatment
Individual response to medication
Hair follicles that are still producing fine, thin hairs generally have a better chance of responding than areas that have been completely bald for many years.
This is why early treatment often provides better outcomes than waiting until significant hair loss has occurred.
When Should You See a Dermatologist?
Not all hair loss is caused by male pattern hair loss.
Other conditions, including telogen effluvium, alopecia areata, scalp inflammation, nutritional deficiencies and scarring alopecia, can also cause thinning.
A dermatologist can assess the pattern of hair loss, examine the scalp and hair follicles, and determine whether further investigations are necessary.
Early assessment is particularly important if hair loss is sudden, patchy, rapidly progressive or associated with scalp symptoms.
Final Thoughts
Male pattern hair loss is common, but effective treatments are available to help slow its progression and maintain hair density.
Topical minoxidil and oral finasteride remain important evidence-based treatments, while other options may be considered depending on individual circumstances.
The key to successful treatment is to:
Start treatment early
Apply medication correctly and consistently
Understand that temporary shedding may occur
Allow at least 6–12 months to assess treatment response
Continue long-term maintenance when treatment is beneficial
With appropriate treatment and realistic expectations, many men can successfully manage hair loss and preserve their existing hair.
If you are experiencing a receding hairline, thinning crown or progressive hair loss, a dermatology consultation can help identify the underlying cause and determine the most suitable treatment options.
