Hair Loss in Women Over 40: Hormones, Thyroid, Stress, GLP-1s & What Actually Helps

Hair loss in women over 40 is common — but it’s rarely caused by just one thing. In this video, I break down the real biology behind midlife hair loss, including how hormones, thyroid function, cortisol, calorie restriction, GLP-1 medications, scalp health, and cellular aging all intersect. If you’ve noticed thinning hair, increased shedding, or slower regrowth in your 40s or 50s, this episode explains what’s happening beneath the surface — and why chasing a single supplement or product usually doesn’t work. We cover: • The difference between telogen effluvium and hormone-related hair thinning • How calorie deficits and rapid weight loss affect thyroid and cortisol • Why GLP-1 medications don’t directly cause hair loss — but under-eating can • The role of estrogen, progesterone, and androgen sensitivity • Micronutrients needed for healthy hair (iron, zinc, copper, protein) • Scalp biology and why it matters • Microneedling, PRP, exosomes, and topical copper peptides (AHK-Cu, GHK-Cu) • The OS-01 peptide and senescent cell signaling • An honest discussion of minoxidil • Why hair loss reflects what was happening in your body months ago Hair follicles are metabolically active tissue. When the body perceives stress — whether from dieting, hormonal shifts, inflammation, or aging — hair is often one of the first places we see change. This video is educational only and is designed to help you understand the systems biology of hair loss so you can make informed decisions.
