Male Hair Loss – Understanding the Causes and Your Treatment Options
Male hair loss is one of the most common concerns we see in our Auckland Hair Again Clinic. The majority of men experience male pattern hair loss (androgenetic alopecia), an inherited condition that causes hair follicles to gradually shrink over time. As the follicles become smaller, each new hair grows finer, shorter, and weaker until hair growth eventually slows or stops altogether.
The good news is that hair loss doesn't have to be inevitable. The earlier treatment begins, the greater the opportunity to preserve existing hair, reactivate weakened follicles, and slow further progression. At Hair Again Clinic, our goal is to extend the natural growth phase of your hair, improve follicle health, and help you maintain thicker, healthier hair for longer.
Using advanced scalp analysis and evidence-based regenerative treatments including PRP, PRF, GFC, Regenera Activa®, Exosomes and personalised home care, we create tailored treatment plans designed around your stage of hair loss, your goals, and your lifestyle.
Male hair loss affects millions of men and often begins gradually with a receding hairline, thinning crown, or reduced hair density. While it is a common condition, it can have a significant impact on confidence and self-esteem. At Hair Again Clinic, we specialise in identifying the underlying cause of hair loss and creating personalised treatment plans designed to restore healthier, thicker hair.
Understanding Male Pattern Hair Loss
Male pattern hair loss, also known as androgenetic alopecia, is the most common cause of hair thinning in men. It occurs when genetically sensitive hair follicles gradually shrink under the influence of dihydrotestosterone (DHT). As the follicles become smaller, each new hair grows finer, shorter, and lighter until growth eventually stops.
The condition usually develops gradually and follows a predictable pattern. For many men, it begins with a receding hairline around the temples, thinning through the crown, or a combination of both. Without treatment, these areas can continue to thin over time while the hair around the sides and back of the scalp typically remains unaffected.
How do I know if I'm losing my hair?
One of the biggest challenges with male pattern hair loss is that it often progresses so slowly that many men don't notice the changes until significant thinning has already occurred. Others become concerned about hair loss long before there is any real evidence of it.
Common early signs include:
-
A receding hairline, particularly around the temples.
-
Increased visibility of the scalp under bright lighting.
-
Thinning through the crown or vertex.
-
Hair appearing finer or less dense than it was previously.
-
More hair shedding than usual when washing or styling.
At Hair Again Clinic, we use advanced trichoscope scalp imaging to assess your hair density, identify early follicle miniaturisation, and determine whether your hair loss is progressing. Detecting changes early allows treatment to begin before significant follicle loss occurs, giving you the best opportunity to maintain and restore healthy hair growth.
Recognising the Pattern
Unlike many other forms of hair loss, male pattern hair loss affects the top of the scalp while preserving the hair on the sides and back. This creates the characteristic "horseshoe" pattern seen in more advanced stages.
Hair loss may present as:
-
A receding frontal hairline.
-
Thinning at the crown.
-
Diffuse thinning across the top of the scalp.
-
A combination of frontal and crown hair loss.
Because every individual experiences hair loss differently, a professional assessment is the best way to determine your stage of hair loss and identify the most effective treatment plan.
Patterns of Hair Loss
There are general patterns of Male Pattern Hair Loss – we are quite confident that one of these will bear a similarity to your own pattern. Below you will find a summary of each.
Different Types of Hair Loss in Men.
Hair loss affects every man differently. While male pattern baldness is the most common cause, other conditions can also lead to thinning, patchy hair loss, or excessive shedding. Identifying the specific pattern of hair loss is the first step towards choosing the most effective treatment.
At Hair Again Clinic, we use advanced scalp analysis and microscopic imaging to accurately diagnose the cause of your hair loss before recommending a personalised treatment plan.
Androgenetic
Alopecia
The most common cause of hair loss in men, androgenetic alopecia is an inherited condition caused by a genetic sensitivity to the hormone DHT (dihydrotestosterone). Hair follicles gradually shrink over time, producing finer, shorter hairs before eventually stopping hair production altogether.
Typical signs include:
-
Receding hairline
-
Thinning through the temples
-
Crown thinning
-
Progressive loss across the top of the scalp
-
Preserved hair around the sides and back
Diffuse
Thinning
Rather than affecting one specific area, diffuse thinning causes a gradual reduction in hair density across the entire scalp. Hair may appear finer, flatter and less dense without obvious bald patches.
Common causes include:
-
Stress
-
Nutritional deficiencies
-
Illness
-
Medications
-
Hormonal changes
-
Early androgenetic alopecia
Telogen
Effluvium
Telogen effluvium is a temporary form of excessive hair shedding that usually occurs two to four months after a physical or emotional stressor.
Common triggers include:
-
Surgery
-
Rapid weight loss
-
Severe illness
-
High fever
-
Emotional stress
-
Certain medications
-
Nutritional deficiencies
The condition often improves once the underlying trigger is addressed, although treatment may help encourage faster recovery.
Alopecia
Areata
Alopecia areata is an autoimmune condition where the immune system mistakenly attacks healthy hair follicles, resulting in smooth, round patches of hair loss.
The condition can affect the scalp, beard, eyebrows and other body hair. Hair may regrow naturally, although some people experience recurring episodes.
Scarring
Alopecia
A less common group of inflammatory conditions that permanently damage the hair follicles.
Scarring alopecia refers to a group of inflammatory conditions that permanently destroy hair follicles and replace them with scar tissue.
Early diagnosis and treatment are essential to preserve any remaining healthy follicles.
Hair Loss Following Weight Loss or Medication
Rapid weight loss, medications such as GLP-1 weight-loss treatments, chemotherapy, anabolic steroids, and some prescription medications may contribute to increased hair shedding.
In many cases, hair growth improves once the underlying cause is managed, although regenerative treatments can often help support recovery.
What Causes Hair Loss in Men?
Hair loss in men can develop for many different reasons. While male pattern hair loss (androgenetic alopecia) is the most common cause, factors such as hormones, genetics, stress, illness, medications, nutritional deficiencies, and certain medical conditions can all contribute to hair thinning and excessive shedding.
Understanding the underlying cause is essential because not all hair loss is treated the same way. At Hair Again Clinic, we use advanced scalp analysis and microscopic imaging to assess your hair follicles, scalp health, and hair growth cycle before recommending a personalised treatment plan.
Genetics & DHT
The leading cause of male hair loss is an inherited sensitivity to dihydrotestosterone (DHT). Over time, DHT causes susceptible hair follicles to gradually shrink (miniaturise), resulting in finer, shorter hairs until the follicle eventually stops producing hair.
Hormonal Changes
Hormones play an important role in regulating the hair growth cycle. Changes in testosterone metabolism, thyroid disorders, or other hormonal imbalances can disrupt normal hair growth and contribute to thinning or increased shedding.
Stress & Lifestyle
Physical or emotional stress can push large numbers of hair follicles into the resting phase of the hair cycle, resulting in increased shedding several months later. Poor sleep, smoking, excessive alcohol consumption, and chronic stress may also negatively affect scalp health and hair growth.
Nutritional Deficiencies
Healthy hair depends on a consistent supply of nutrients. Low levels of iron, vitamin D, zinc, vitamin B12, folate, and inadequate protein intake can weaken hair follicles and contribute to thinning or excessive hair loss.
Medical Conditions
Certain medical conditions may contribute to hair loss, including thyroid disease, autoimmune conditions such as alopecia areata, scalp disorders, diabetes, chronic illness, and inflammatory scalp conditions. Identifying these factors is an important part of developing the right treatment plan.
Medications
Some prescription medications may cause increased hair shedding as a side effect. These may include certain blood pressure medications, antidepressants, anticoagulants, acne medications, chemotherapy drugs, anabolic steroids, and some newer weight-loss medications such as GLP-1 therapies.
Rapid Weight Loss
Significant or rapid weight loss can temporarily interrupt the normal hair growth cycle, leading to a condition known as telogen effluvium. This type of hair loss often occurs two to four months after substantial weight loss, surgery, illness, or a major dietary change. While it is usually temporary, supportive treatments can help encourage healthier regrowth.

Why Early Treatment Matters
Hair follicles affected by male pattern hair loss gradually become smaller over time, producing finer and shorter hairs until they eventually stop growing altogether. Seeking treatment early provides the greatest opportunity to preserve existing follicles, slow further hair loss, and achieve better long-term outcomes.
Treating Male Pattern Baldness
Male Pattern Hair Loss (androgenetic alopecia) is a progressive condition, but with early diagnosis and the right treatment plan, it can often be slowed, stabilised, and in many cases significantly improved.
At Hair Again Clinic, we understand that every man's hair loss journey is different. The severity of hair loss, age, genetics, overall health, and treatment goals all influence which approach is most appropriate. That's why we begin with a comprehensive consultation and advanced scalp analysis before recommending a personalised treatment plan.
Using the latest evidence-based regenerative therapies, medical treatment options, and ongoing home care, we focus on preserving existing hair, stimulating dormant follicles, improving scalp health, and supporting stronger, healthier hair growth.
The earlier treatment begins, the greater the opportunity to protect existing follicles and achieve the best possible long-term results.
Frequently Asked Questions
How do I know if I'm losing my hair?
Hair loss often begins gradually. Early signs include a receding hairline, thinning through the crown, increased hair shedding when showering or styling, or noticing more scalp visibility in photographs. An early assessment can help determine the cause before significant hair loss occurs.
What is the most common cause of hair loss in men?
The most common cause is Male Pattern Hair Loss (androgenetic alopecia), an inherited condition caused by genetic sensitivity to the hormone DHT (dihydrotestosterone). It typically affects the temples, frontal hairline, and crown.
Can male pattern hair loss be stopped?
While it cannot always be completely prevented, early treatment can often slow its progression, preserve existing hair, and stimulate healthier hair growth. The earlier treatment begins, the better the long-term outcome.
What treatments are available for men's hair loss?
Treatment is tailored to your individual diagnosis and may include:PRP (Platelet-Rich Plasma)PRF (Platelet-Rich Fibrin)Growth Factor Concentrate (GFC)Regenera Activa®Exosome Therapy
Medical treatment options:
DHT blockers (where appropriate) Nutritional support
Can stress cause hair loss?
Yes. Significant physical or emotional stress can trigger Telogen Effluvium, a temporary increase in hair shedding that usually occurs two to four months after the triggering event.
Can hair grow back after thinning?
Many men experience significant improvement with early intervention. If hair follicles remain active, treatments can often strengthen weakened follicles, improve hair density, and encourage healthier growth.
Is treatment painful?
Most treatments are very well tolerated. We use gentle techniques and can apply local anaesthetic where appropriate to maximise comfort during procedures such as PRP, PRF, GFC, Regenera Activa®, and Exosome Therapy.
How long does it take to see results?
Hair grows slowly, so most clients begin noticing improvement after 3–6 months, with continued progress over the following 6–12 months. Individual results vary depending on the type and severity of hair loss.
When should I seek treatment?
The sooner the better. Hair follicles gradually become smaller over time, making treatment less effective if hair loss is left untreated for many years. Early diagnosis gives the greatest opportunity to preserve existing hair and achieve the best possible results.
