Causes of Hair Loss

Common causes of male hair loss

Once hair loss has occurred over a long period, the condition becomes harder to reverse. Seeking treatment at the first signs of hair loss is the best way to regrow hair.

Male pattern baldness is the most common form of alopecia. Beginning as thinning hair, male pattern baldness results in a receding hairline and balding on the top of the scalp.

Hair loss typically starts to occur in men in their 20s, with symptom severity worsening with age.

Common causes of hair loss

Medically known as androgenic alopecia, male pattern baldness is the most common form of hair loss affecting men in their 20s, 30s, and 40s. Characterised by a gradual loss of hair that begins any time after puberty, the first signs of hair loss to look out for are balding hair, hair thinning, and receding hair.

As well as being age-related, male pattern hair loss is caused by a combination of genetic factors (having a family history of balding) and being androgen-dependent; specifically, having a sensitivity to a male hormone called dihydrotestosterone (DHT).

Hair growth cycle

Humans produce 1-kilometre of hair a month in a normal hair growth cycle. During this cycle, each follicle progresses through three growth phases (anagen, catagen, and telogen) and one shedding phase (exogen).


The anagen phase is an active growth phase whereby follicles develop and appear on the scalp. Anagen is the longest phase of the hair growth cycle, with hair follicles lasting 2.5 to 5 years on the scalp.

The catagen phase is a short transitional phase from active growth to inactivity. Catagen is a short phase of the hair growth cycle, lasting around 2 weeks.

The telogen phase is the resting phase, whereby follicles spend around 2 to 4 months in a state of rest. Hair follicles don’t grow during the telogen phase, yet they don’t shed either.

The exogen phase is the shedding phase. Once hair shafts outgrow the telogen phase, they detach from the follicle and fall out.


DHT production

Dihydrotestosterone (DHT) is a naturally occurring by-product of testosterone that plays a key role in a man’s transition from puberty to manhood.

Once a man reaches adulthood, DHT causes hair follicles to weaken and new follicles to stop growing.

Men with male baldness have more DHT in the balding part of their scalp than in other parts, resulting in increased hair loss.

Various areas of the scalp may be affected by hair loss, although thinning is predominantly seen as a receding hairline or balding on the top of the scalp.

Trauma and stress-related hair loss

Telogen effluvium is a type of temporary hair loss resulting from a traumatic or stressful event.

Causes of this hair loss include illness, metabolic stress, surgery, hormonal changes, trauma, infection, nutritional deficiencies, and the use of certain medications.

Once the cause of telogen effluvium has been identified, the condition can be treated, and healthy hair growth can occur.

Hair loss FAQs

How does hair loss treatment work with hub.health?

hub.health uses a secure digital health platform to provide discreet, convenient, and affordable access to hair loss treatment from an Australia-based medical team, all from the privacy of your home.

After completing the online questionnaire, your assigned clinician will determine if you’re a candidate for hair loss treatment. If you’re successful, we’ll organise fast delivery to your door (we’ll even manage your repeats when they’re due). If your clinician identifies a potential risk in issuing hair loss treatment, they’ll likely refer you to an in-person GP for further review.

What hair loss treatments do you offer?

The hub.health medical team issue prescription medication to treat male pattern baldness (androgenic alopecia). Prescription hair loss medication helps to maintain current hair volume while preventing further loss and potentially regrowing hair in areas where it has been lost.

Our clinicians may also prescribe Minoxidil 5% non-prescription as a topical or capsule treatment, which has been proven as one of the most effective treatments for hair regrowth. Your hair loss treatment will be specifically tailored to you, so make sure you don’t share with anyone else, even if they claim to have the same condition as you.

How long does it take to see results?

Hair loss treatment programs can take 3 to 6 months of daily use for visible changes to occur, and up to one year for maximum results. Like all medications, results vary from person to person based on individual circumstances.

Can I speak with my assigned clinician at any time?

Of course! Our online platform enables ongoing support whenever you need it. To chat with your medical team, log into your profile, head to the ‘Products’ tab and select ‘Manage Treatment’. This is where you can message your clinician.

Our team is also available at [email protected] Drop us a line, anytime.
