The Bald Truth about Hair Loss

What is Hair Loss?

Hair loss, medically known as alopecia, is one of Canada’s most common conditions affecting men. Canadian consensus estimates 40–50% of men experience androgenetic alopecia by age 50. In British Columbia, it impacts men across all backgrounds, ethnicities, and sexual orientations.

Hair loss occurs when the hair growth cycle is disrupted or follicles are damaged. Each scalp follicle cycles through growth (anagen ~2–6 years), transition (catagen ~2–3 weeks), and rest/shedding (telogen ~3 months) phases. In androgenetic alopecia (male pattern baldness), genetics and DHT sensitivity cause progressive follicle miniaturization, shortening anagen and producing thinner hairs until follicles stop producing visible hair.

Hair loss is not a choice, lifestyle failure, or masculinity issue, it’s a genetic medical condition deserving evidence-based care.

Hair loss presents differently depending on the cause. Recognizing patterns helps you and your healthcare provider select effective treatment. Common presentations in Canadian men:

Gradual thinning on the top of the head

Most common, androgenetic alopecia (male pattern baldness). Hair recedes at temples and thins at crown per Norwood Scale (stages 1–7). DHT shrinks follicles over years, producing finer/shorter hairs. Often starts late teens/20s.

Circular or patchy bald spots

Alopecia areata, autoimmune attack on follicles causing smooth, coin-sized patches on scalp/beard/eyebrows. Affects ~2% lifetime prevalence. Normal skin, no scaling.

Sudden Shedding

Telogen effluvium, excess hair loss (>100/day) when washing/combing after shock (surgery, illness, stress, rapid weight loss). Temporary; regrows once trigger resolves.

Full-body hair loss

Chemotherapy or severe deficiencies (iron, vitamin D, zinc) cause diffuse shedding. Regrowth follows treatment cessation.

Scaly, Spreading Patches

Tinea capitis (ringworm) or scalp psoriasis, inflamed, itchy, scaly areas with broken hairs. Requires antifungal/anti-inflammatory Rx.

Normal daily hair shedding is 50–100 hairs. Seek medical advice if you notice:

• Sudden or rapid hair loss over weeks/months
• Hair loss with fatigue, weight changes, or other symptoms (thyroid, anemia, etc.)
• Bald patches with redness, itching, scaling, or inflammation
• Significant psychological distress, anxiety, or social withdrawal from hair loss
• You’re considering Health Canada-approved treatments like minoxidil (OTC, 2%/5%) or finasteride (Rx, 1 mg) and want proper guidance.
• You’re interested in advanced options like PRP therapy, low-level laser therapy, or FUE hair transplants available at BC clinics

Hair loss has many plausible causes, and often more than one factor is involved. Understanding what is driving your specific hair loss is essential to choosing the right treatment approach.

Hereditary

Androgenetic alopecia, commonly known as male pattern baldness, is by far the most common cause of hair loss in men, accounting for the majority of cases. This hereditary condition is driven by a sensitivity of certain hair follicles to dihydrotestosterone (DHT), a potent androgen formed from testosterone. In genetically susceptible follicles, long‑term exposure to DHT causes progressive miniaturization, so hairs become thinner and shorter with each cycle until some follicles stop producing visible hair.

Contrary to popular belief, the tendency to develop androgenetic alopecia can be inherited from either parent, not just the maternal grandfather’s side. Epidemiologic studies suggest that roughly 30–50% of men show male pattern baldness by age 50, making it one of the most common conditions men experiences. It is a very common genetic variation rather than a sign of poor health, and effective treatments are available for men who wish to slow or partially reverse the process.

Age

As men age, hair growth naturally slows. The anagen (growth) phase of each follicle becomes shorter with each cycle, meaning hairs do not grow as long and are replaced less efficiently. This age-related thinning is distinct from androgenetic alopecia but often occurs alongside it. Hormonal shifts associated with aging, including changes in testosterone and DHT levels, further compound the effect on hair follicles. Preventive hair care and early intervention can significantly slow this process.

Scalp Infection

Fungal infections of the scalp, particularly tinea capitis, can cause patchy hair loss in affected areas. This type of scalp infection is more common in children but can occur in adults, especially those with compromised immune function. Bacterial infections, folliculitis, and seborrheic dermatitis can also damage hair follicles and disrupt growth cycles. Ketoconazole shampoo, an antifungal agent, is sometimes used both to treat fungal scalp conditions and, off label, as a component of hair loss management due to its mild anti-androgen properties.

Medications

A wide range of medications can trigger medication-induced hair loss. Common culprits include chemotherapy drugs, blood thinners (anticoagulants), betablockers, antidepressants, retinoids, anabolic steroids, and some antifungal medications. This type of hair loss, a form of telogen effluvium, typically begins two to four months after starting a new medication and is often reversible once the drug is discontinued or changed. If you suspect a medication is causing your hair loss, speak with your prescribing physician before stopping any treatment.

Scalp Psoriasis

Scalp psoriasis is a chronic inflammatory skin condition that produces thick, silvery-white scales and red patches on the scalp. While psoriasis itself does not directly destroy hair follicles, the inflammation, scratching, and harsh removal of scales can cause temporary hair loss in affected areas. Traction alopecia, hair loss caused by repeated tension or pulling, can worsen matters if individuals aggressively try to remove plaques. Treatment of the underlying psoriasis typically leads to hair regrowth.

Thyroid Disease

Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can cause diffuse hair loss across the entire scalp. Thyroid hormones play a direct role in regulating hair follicle cycling, and when levels are disrupted, widespread shedding can occur. This is an important cause to identify and rule out, since thyroid disorder is fully treatable, and with proper thyroid management, hair loss typically reverses. A simple blood test (TSH) can screen for thyroid dysfunction. Nutrition and hair health are linked, as thyroid disease can also interfere with the absorption of iron, biotin, and other hair-supporting nutrients.

Multiple factors can increase a man’s likelihood of experiencing significant hair loss. Understanding these risk factors can motivate early action and preventive hair care:

• Family history: Having first-degree relatives with androgenetic alopecia significantly increases your own risk, regardless of whether those relatives are on your mother’s or father’s side.
• Hormonal imbalances: Elevated DHT sensitivity, low testosterone, or thyroid disorders can all accelerate hair loss.
• Nutritional deficiencies: Iron deficiency, vitamin D insufficiency, low biotin, and zinc deficiency are all associated with increased hair shedding and poor follicle health. Nutrition and hair health are deeply interconnected.
• Chronic psychological stress: Prolonged emotional stress is a welldocumented trigger for telogen effluvium, causing stress-related hair loss months after the stressful event.
• Medical conditions: Autoimmune disorders (including those that cause autoimmune hair loss like alopecia areata), scalp infections, and inflammatory skin conditions all pose elevated risk.
• Hairstyling practices: Tight braids, ponytails, cornrows, or extensions can cause traction alopecia, hair loss from chronic mechanical tension on the follicle.
• Smoking: Research suggests smoking may reduce blood flow to hair follicles and accelerate androgenetic alopecia.
• Certain medications: As noted above, several drug classes list hair loss as a documented side effect.

While hereditary hair loss cannot always be prevented, there is convincing evidence that early intervention, healthy lifestyle choices, and targeted treatments can significantly slow progression and support healthier hair for longer. Here is what the evidence supports:

Start evidence-based treatment early:

Minoxidil (topical or oral) and Finasteride are the two Health Canada approved treatments with the strongest clinical evidence for male pattern baldness. Minoxidil works by stimulating blood flow to hair follicles and prolonging the growth phase. Finasteride works by inhibiting the enzyme that converts testosterone to DHT. Both are most effective when started early before significant follicle damage has occurred. Consult a physician before starting either.

Support nutrition and hair health:

Ensure adequate intake of iron, vitamin D, biotin, and zinc through a balanced diet or supplementation as guided by bloodwork. Deficiencies in these key nutrients can exacerbate shedding and impair regrowth.

Manage stress proactively:

Stress-related hair loss is real and preventable. Regular physical activity, quality sleep, mindfulness practices, and professional psychological support can mitigate the hormonal effects of chronic stress on hair follicles.
