Why Your Hair Is Thinning: Stress, Hormones, GLP-1s & More with Dr. Heather Woolery-Lloyd

Dermatologist Dr. Heather Woolery-Lloyd joins SheMD for a comprehensive conversation about why women experience hair thinning, shedding and breakage throughout different stages of life.
Dr. Woolery-Lloyd explains how postpartum hormone changes, perimenopause and menopause, stress, PMOS, thyroid disease, autoimmune conditions, nutritional deficiencies and cosmetic damage can all affect hair health.
She also breaks down telogen effluvium, a common form of stress-related shedding that can appear 3 to 6 months after a major life event, including childbirth, surgery, illness, divorce or another period of significant stress.
We also discuss hair loss in women taking GLP-1 medications and why rapid weight loss, inadequate protein intake and nutritional deficiencies may contribute to increased shedding.
Dr. Thaïs Aliabadi and Dr. Woolery-Lloyd walk through the workup and treatment options they use with patients, including lab testing, minoxidil, spironolactone, PRP, light therapy, supplements and lifestyle changes.
Plus, we answer common questions about tight hairstyles, extensions, washing, brushing, heat damage and what women should know before starting a hair supplement.
If your hair has changed and you do not know why, this episode is a great place to start.
