Hair is more than just a physical attribute—for many women, it’s a vital part of identity and self-confidence. So, when hair starts to thin or fall out, it can be deeply unsettling. The good news is that you’re not alone. Studies show that over half of women experience some form of hair loss after menopause. But hair loss can happen at any age, and understanding the underlying causes is the first step toward addressing it.
In this post, we’ll explore four common types of hair loss in women, backed by dermatological expertise.
1. Female Pattern Hair Loss (Androgenetic Alopecia)
Female pattern hair loss (FPHL) is the most common type of hair loss in women. According to the Journal of the American Academy of Dermatology, it affects up to 40% of women by age 50. This condition is often genetic and hormonal. As women approach menopause, androgen levels—including testosterone—may rise. These hormones can be converted into DHT, which shortens the hair growth cycle and miniaturizes hair follicles, leading to thinner strands and a more visible scalp.
As noted by Dr. Paradi Mirmirani, a specialist in hair disorders, FPHL is chronic and progressive but manageable with early intervention.
2. Telogen Effluvium (TE)
Telogen effluvium is characterized by sudden, significant shedding, usually triggered by physical or emotional stress. Common triggers include surgery, illness, childbirth, or major life changes. The shedding typically begins about three months after the stressful event.
As Dr. Michele Green explains, high cortisol levels may shorten the hair’s growth phase, pushing more hairs into the shedding phase. The encouraging news is that TE is usually temporary. Postpartum hair loss is a classic example. Recent research also links rapid weight loss—such as with GLP-1 medications like Ozempic—to TE, due to the stress such changes place on the body.
3. Alopecia Areata
Alopecia areata is an autoimmune condition where the immune system mistakenly attacks hair follicles. This leads to sudden hair loss in round, smooth patches on the scalp or body. While the exact cause is unknown, genetics are believed to play a role.
The hair follicles are not permanently destroyed, and hair can regrow—though the timing is unpredictable. As Dr. Melissa Piliang notes, this condition can come and go without warning.
4. Traction Alopecia
Traction alopecia results from repeated tension on the hair follicles due to tight hairstyles such as braids, ponytails, or extensions. Over time, this strain can reduce blood flow and damage follicles, leading to permanent hair loss—especially along the hairline.
Dr. Mirmirani advises paying attention to scalp tenderness: “If your scalp hurts, that’s a great indicator that you need to switch up your style.”
When to Seek Help
If you’re noticing more hair in your brush or shower drain, it’s important to consult a board-certified dermatologist. They can diagnose the root cause and recommend a personalized treatment plan. Early intervention is key—especially for conditions like traction alopecia or female pattern hair loss, where timely care can prevent further loss.
For further reading, reputable sources like the American Academy of Dermatology and peer-reviewed journals offer in-depth insights into these hair loss types and the latest treatments.
Final Thoughts
Hair loss can feel isolating, but it’s a shared experience for many women. By understanding these common causes and seeking professional guidance, you can take control of your hair health—and move toward thicker, healthier hair with confidence.
