Why hair loss happens
Shedding some hair daily is completely normal, most people lose 50 to 100 strands a day. Hair loss becomes worth investigating when you notice a receding hairline, a widening parting, thinning at the crown, patches, or a sudden increase in shedding. The cause matters enormously, because the right treatment depends entirely on the diagnosis.
The most common causes
- Pattern hair loss (androgenetic alopecia): genetic and hormone-related, the most common type in both men and women
- Telogen effluvium: temporary shedding after stress, illness, childbirth, surgery, or rapid weight loss
- Nutritional gaps such as low iron, or thyroid problems
- Alopecia areata: an autoimmune condition causing patchy loss
- Traction alopecia from tight hairstyles, and damage from harsh styling or chemical treatments
Timing is a clue
Sudden diffuse shedding a few months after a stressful event often points to telogen effluvium, which is usually temporary. Gradual thinning over years points more to pattern hair loss.
Treatments with real evidence
There's a lot of snake oil in the hair-loss market. A few approaches have genuine scientific backing, but the right choice depends on your diagnosis and should be discussed with a clinician.
- Topical minoxidil, available over the counter in many regions, can help pattern hair loss in both men and women
- Certain prescription oral medications for pattern hair loss in men, which require a doctor's assessment and have important considerations
- Treating an underlying cause: correcting iron deficiency or thyroid issues, or easing the trigger behind telogen effluvium
- Gentler styling and avoiding tight, pulling hairstyles to prevent traction damage
Prescription hair-loss medications carry specific risks and warnings, including for anyone pregnant or planning a pregnancy. Always get a clinician's guidance rather than buying from unverified online sellers, and never share these medicines.
Myths worth ignoring
- Wearing hats does not cause baldness
- Frequent washing does not cause permanent hair loss
- Most expensive 'thickening' supplements won't help unless you have a genuine deficiency
When to see a doctor
See a clinician if hair loss is sudden, patchy, comes with scalp pain, redness or scarring, or is distressing you. Scarring hair loss in particular needs prompt assessment because early treatment can prevent permanent loss.
Don't ignore these
Hair loss with a rapidly spreading rash, severe scalp pain, or signs of systemic illness should be assessed promptly. In a medical emergency call 911 (US/CA), 999 (UK), or 112 (EU).
