Before Choosing a Treatment

Androgenetic alopecia — male pattern baldness driven by DHT — is the most common cause of progressive hair loss in men globally. In India, telogen effluvium from stress, nutritional gaps, illness and lifestyle triggers is also highly prevalent. A dermatologist evaluation helps identify the correct pattern and cause. Results vary.

Male pattern baldness typically shows as a receding hairline at the temples (M-shape), thinning at the crown, or both. Hair in affected areas becomes progressively finer over time. Family history is a major risk factor. A dermatologist confirms through clinical examination and trichoscopy. Results vary.

Early signs include a slowly receding hairline at the temples, hair becoming finer at the crown, a changing M-shaped hairline, reduced density visible in photos or under bright light, and widening at the vertex. Earlier identification generally allows more management options. Dermatologist evaluation recommended.

Hairline recession is most commonly caused by androgenetic alopecia — DHT causing gradual miniaturisation of genetically sensitive follicles at the temples and frontal hairline. Speed depends on genetic sensitivity and DHT levels. A dermatologist helps distinguish normal maturation from progressive recession and guides appropriate management.

Crown thinning is most often caused by male pattern baldness — androgenetic alopecia — where DHT drives follicle miniaturisation at the top-back scalp. It may also result from diffuse telogen effluvium or nutritional deficiency. Dermatologist evaluation with trichoscopy identifies the pattern.

DHT is the primary driver of androgenetic alopecia in genetically predisposed men. However, not all male hair loss is DHT-driven — stress, fever, nutritional deficiency, scalp inflammation and medication can all cause hair fall without DHT involvement. Identifying the correct cause determines appropriate management.

Yes. Severe physical or emotional stress can trigger telogen effluvium — diffuse shedding 2–3 months after the stressful event. This is typically temporary. Doctor evaluation recommended if severe or prolonged to rule out concurrent pattern loss. Results vary.

Dandruff itself does not directly cause permanent hair loss, but significant scalp inflammation from seborrheic dermatitis can affect the scalp environment, and excessive scratching can cause mechanical damage. Managing the scalp condition typically reduces associated shedding. Doctor evaluation for persistent cases.

The link between creatine and hair loss is based on limited evidence from a single small study showing increased DHT conversion, not confirmed in larger clinical trials. High-intensity training may theoretically influence androgen levels in genetically predisposed men. A dermatologist evaluation can assess your pattern and contributing factors. Results vary.

Smoking is associated with reduced scalp blood flow and oxidative stress which may worsen follicle health. Heavy alcohol can contribute to nutritional deficiencies affecting hair. Neither directly causes male pattern baldness, but both may worsen progression in genetically predisposed individuals.

Minoxidil has strong clinical evidence for male pattern hair loss in suitable patients. It may support hair retention and regrowth when used consistently. Initial shedding in the first weeks is common and temporary. Benefits require ongoing use. Dermatologist evaluation recommended before starting to confirm suitability and concentration. Results vary.

No. Finasteride is prescription-only for adult men with male pattern hair loss. It is contraindicated in women of childbearing potential and not for children or adolescents. A small proportion of men may experience sexual side effects, usually reversible on stopping. Rare cases of persistent side effects have been reported. Dermatologist evaluation essential before starting. Results vary.

Minoxidil is a topical vasodilator applied to the scalp to support hair growth and retention — it works regardless of DHT levels and is available without prescription. Finasteride is an oral prescription medicine that reduces DHT production by blocking 5-alpha-reductase. They work differently and can be used together under medical guidance. Dermatologist evaluation determines what is appropriate.

See a dermatologist for sudden or rapid hair loss, patchy bald spots, fast hairline recession, scalp pain or crusting, shiny patches, systemic symptoms, hair loss after new medication, confusion about treatment, or no improvement after 3–6 months of appropriate routine care. Early evaluation leads to better outcomes.

Hair transplant may be considered when hair loss has stabilised, donor hair is adequate, Norwood stage is suitable and medical treatment options have been explored. Specialist evaluation is essential. Transplant does not stop ongoing pattern loss without concurrent medical treatment. Results vary significantly.

Yes. Hair fibres provide immediate cosmetic coverage for crown thinning. They work best when some hair remains to anchor to. They are a cosmetic support tool — not a medical treatment — and can be used safely alongside medical treatment. Results vary by density and coverage needs.

No. The AI Hair Test is an educational screening and directional tool — not a medical diagnosis. It does not replace clinical examination, trichoscopy or blood tests. For prescription-linked, fast-progressing or patchy hair loss, a qualified dermatologist assessment is essential.
