Hair loss in women can take many forms, and the cause matters. Female pattern hair loss commonly appears as progressive thinning over the top of the scalp or a widening part, but sudden shedding can have very different triggers.
Common signs
Look for a widening center part, reduced ponytail volume, more visible scalp over the crown or top, and gradual loss of density. A dermatologist can distinguish pattern hair loss from shedding disorders and inflammatory or autoimmune causes.
Other causes of thinning in women
Childbirth, major illness, surgery, rapid weight loss, thyroid disease, iron or other nutritional problems, medications and significant stress can contribute to shedding. Tight hairstyles can contribute to traction alopecia.
Minoxidil for women
Products containing topical minoxidil are approved for female pattern hair loss, but directions vary by formulation. Women should follow the Drug Facts panel of the exact product and avoid minoxidil during pregnancy or breastfeeding unless specifically directed by a healthcare professional.
Scalp and cosmetic hair care
Gentle cleansing, conditioning and minimizing breakage can improve the appearance and manageability of thinning hair. Volumizing products can make existing strands look fuller, but cosmetic products should not be described as treating the underlying medical cause.
When to seek help
See a dermatologist for sudden or patchy loss, scalp symptoms, rapidly worsening thinning, or when the cause is unclear. A clinician may recommend examination, blood tests or other evaluation depending on the history.
