Lupus is an autoimmune disease most common in women aged 15–45. A hallmark “butterfly rash” may bloom across the cheeks, and hair loss appears as raised, red, coin-shaped patches that eventually crust over. Once a follicle is scarred, regrowth is unlikely—early diagnosis is crucial.
2. Polycystic Ovary Syndrome (PCOS)
PCOS disrupts hormone balance, ramping up androgens that weaken scalp hair while paradoxically increasing body hair elsewhere. If thinning at the crown comes with irregular periods or acne, ask your OB-GYN for a hormone panel and pelvic ultrasound.
3. Stress Syndrome
Emotional strain from deadlines, shift work, over-training, or crash dieting can push hairs prematurely from the growth phase into dormancy, then mass shedding (telogen effluvium). Stress also constricts blood vessels, starving follicles of nutrients. Rest, mindfulness, and balanced meals are non-negotiable for recovery.
4. Thyroid Disorders
Whether overactive or underactive, a misfiring thyroid skews metabolism and interferes with the hair cycle. Classic hyperthyroid clues—insomnia, palpitations, heat intolerance—may grab headlines, but unexplained thinning is often the first whisper. A simple TSH test can reveal the truth.
5. Iron-Deficiency Anemia
You can keep your scalp squeaky-clean and still shed excessively if iron stores are low. Without enough hemoglobin to ferry oxygen, follicles suffocate and release hair prematurely. Boost iron through lean meats, spinach, or supplements under medical guidance.
6. Fungal Scalp Infection (Tinea Capitis)
Ringworm of the scalp spreads by contact and shows up as broken stubble, redness, or oozing pustules. Different fungi produce different severities, but untreated cases can destroy follicles and cause permanent bald patches. Antifungal medication—and sometimes a short haircut—are your best allies.
Takeaway for Every Woman
Hair is more than a beauty statement—it’s a health barometer. If you spot sudden, excessive shedding or dramatic texture changes, book an appointment with your dermatologist or primary-care physician. Your locks (and overall wellbeing) will thank you.
