When Alison Richards began noticing severe thinning and shedding of her long blonde hair in her 20s, she remembers finding a terrifying handful of strands in the shower and feeling overwhelmed by conflicting online advice from influencers and ads.
Hair loss in women is common: roughly half of women will notice hair thinning at some point. Causes vary, and not every remedy works for every person, so identifying the underlying reason is the first step toward effective care.
How hair normally behaves
Hairs cycle through growth (anagen), transition (catagen) and rest (telogen) phases. Individual hairs usually fall out when replaced by new ones, so shedding is normally staggered. Major physiologic stressors—childbirth, serious illness (including COVID-19), surgery or severe stress—can synchronize hair follicles into the telogen phase and cause a larger, temporary shed (telogen effluvium). In many cases this resolves and hair regrows over months.
When thinning becomes lasting
Permanent or progressive thinning usually reflects other causes. The most common is androgenetic alopecia (female-pattern hair loss), which often begins at the crown and gradually widens the hair part. Less common causes include alopecia areata, an autoimmune disease that produces one or more round bald patches, and scarring (cicatricial) alopecias, which cause permanent follicle loss and are often accompanied by scalp symptoms such as itching, tenderness, redness or pustules.
Why an accurate diagnosis matters
Treatments differ by cause, so seeing a clinician for diagnosis is important. Dermatology appointments can be hard to schedule; primary care can be a good starting point but may not always identify less common or inflammatory conditions. Telehealth services can prescribe standard treatments for pattern hair loss, but they may miss scarring or inflammatory diseases. If the cause is unclear—or if there are scalp symptoms—an in-person dermatology visit is often best.
Established and newer treatment options
– Topical minoxidil (Rogaine) is an over-the-counter foam or solution that can prolong the hair growth phase and is effective for many people with pattern hair loss. Some find it messy; it is generally not recommended during pregnancy or breastfeeding.
– Oral minoxidil is used off-label by some clinicians for women with hair loss, and it is sometimes combined with anti-androgen medications such as spironolactone under medical supervision. These prescriptions require close follow-up because of potential side effects.
– For alopecia areata, newer JAK inhibitor medications have shown greater hair regrowth than placebo in clinical studies, and some agents have been approved for this condition. Corticosteroid injections into affected areas are another option that can induce regrowth for some people.
Coping and community
Hair loss can be emotionally difficult, but many women adapt in ways that feel right for them: scarves, hats, wigs, hairpieces or choosing to go without. Support groups—both in-person and online—offer practical tips and emotional support; organizations and communities help normalize different choices about appearance and redefine beauty beyond hair.
Next steps if you’re experiencing hair loss
Seek a medical evaluation to determine the type of hair loss and appropriate treatments. Ask about expected timelines—most therapies take months to show improvement—and about safety if you’re pregnant, planning pregnancy or breastfeeding. Consider both medical options and support networks as you explore what feels best for your life and well-being.
