Hair loss can be devastating, especially for women who associate their hair with beauty, confidence, and health. While genetics certainly play a role, many women are unaware that everyday factors and life events can also trigger hair thinning or shedding. Triple board-certified dermatologist Dr. Mamina Turegano, MD, explains six common—but often overlooked—causes of hair loss in women, and what you can do to protect your tresses.

1. Postpartum Changes
Many new mothers experience significant hair shedding in the months following childbirth. During pregnancy, higher estrogen levels keep more hair in the growth phase. After birth, those hormone levels drop suddenly, and a lot of hair enters the shedding phase at once. While it can be alarming, this type of hair loss is usually temporary, and hair often regrows within six to twelve months. Maintaining a balanced diet rich in protein, iron, and vitamins can help support recovery.
2. Stress
Chronic stress doesn’t just affect your mood—it can wreak havoc on your hair. High-stress periods can trigger telogen effluvium, a condition where hair prematurely enters the shedding phase. Stress-induced hair loss is often sudden and noticeable. Incorporating stress management techniques such as meditation, yoga, or regular exercise can reduce the impact on your scalp and overall hair health.
3. Menopause
As women approach menopause, hormonal fluctuations can play a significant role in hair thinning. Declining estrogen and progesterone levels can leave hair more susceptible to shedding and breakage. Menopausal hair loss is gradual but persistent, often affecting the crown and frontal hairline. Using gentle hair care products and considering hormone-related therapies with your doctor can help mitigate some of these changes.
4. Poor Sleep
It may seem surprising, but not getting enough quality sleep can contribute to hair loss. Sleep is essential for cellular repair and regeneration, including your hair follicles. Chronic sleep deprivation can disrupt hormone balance, increase stress levels, and slow down the body’s ability to repair and grow hair. Prioritizing seven to nine hours of restorative sleep per night can support not only your hair but your overall health.
5. Medications
Certain prescription medications can have hair loss as an unintended side effect. Drugs for conditions such as thyroid disorders, high blood pressure, depression, and even some contraceptives may trigger shedding. If you notice hair thinning after starting a new medication, it’s worth discussing with your doctor. Sometimes switching medications or adjusting the dosage can significantly reduce hair loss.
6. Illness
Underlying health conditions can also contribute to hair loss. Autoimmune disorders, thyroid imbalances, and chronic illnesses can all disrupt hair growth. Hair loss is often a symptom of something deeper going on in the body. Treating the root cause—whether it’s a thyroid condition or nutrient deficiency—is key to restoring healthy hair growth.
The bottom line
Hair loss in women can feel alarming, but understanding the hidden triggers can help you take control of your hair health. From postpartum hormonal shifts to stress, menopause, lack of sleep, medications, and illness, Dr. Turegano emphasizes that many causes are manageable with the right interventions. If you’re noticing unusual thinning or shedding, it’s always best to consult a qualified dermatologist to identify the cause and create a targeted hair care plan.
