Why is diagnosis the first step?
Because "hair loss" isn't one condition — it's a symptom with many causes, and treatments that work for one cause do little for another. Genetic pattern hair loss, hormonal causes, stress-related shedding, nutritional deficiencies and medical conditions all need different approaches. A dermatologist-led hair loss appointment — including history, examination and sometimes tests — identifies the cause so treatment is targeted, not guesswork.
Common causes of hair loss
- Genetic (pattern) hair loss— the most common type in both men and women (androgenetic alopecia)
- Hormonal factors— including thyroid issues, PCOS, postpartum changes and menopause
- Stress-related shedding (telogen effluvium)— often temporary
- Nutritional deficiencies— iron, vitamin D and others Medical conditions and medications Scalp conditions Identifying which (sometimes more than one) applies to you is the whole basis of effective treatment.
How is hair loss different in men vs women?
Men often experience a receding hairline and crown thinning (classic male-pattern loss), while women more commonly notice diffuse thinning across the top with a preserved hairline. The underlying causes can overlap, but the patterns — and sometimes the contributing factors (hormones feature strongly in women's hair loss) — differ, which affects assessment and treatment.
What treatment options are available?
Depending on the diagnosis, options may include: Medical treatments prescribed and supervised by a dermatologist PRP hair restoration — using your own growth factors to support hair and scalp Laser/light-based approaches Addressing underlying causes (hormones, deficiencies, stress) Post-transplant care for those who've had a transplant Plans are often combined and tailored. Treatments aim to slow loss and support regrowth where possible — honest, individualised expectations matter. See hair restoration.
When should you act?
Sooner rather than later. Many treatments work best earlier, when more hair is still present to preserve — and some causes (like deficiencies or stress-related shedding) are very treatable once identified. If you're noticing increased shedding, thinning or a changing hairline, an assessment is worthwhile, even just for reassurance and a plan. Individual results vary.
