A Dermatologist’s Guide to Hair Health: Postpartum, Perimenopause, GLP-1s & More with Dr. Heather Woolery-Lloyd
Episode 2
Monday, 27 April, 2026
In this episode of The Business of Wellness, Jaclyn London, RD sits down with board-certified dermatologist and lifestyle medicine physician Dr. Heather Woolery-Lloyd, Chief Medical Advisor at Nutrafol, to break down what actually drives hair thinning—and what evidence-based products look like in a category crowded with hype.They discuss why hair changes often follow major physiological stressors like rapid weight loss, postpartum recovery, illness, or GLP-1 use; how hormones, nutrition, and aging affect the hair growth cycle; and why “quick fixes” dominate online conversations despite contradicting dermatologic evidence.Dr. Woolery-Lloyd also explains how clinicians evaluate root causes of hair thinning, what makes a supplement science-backed rather than marketing-driven, and how lifestyle medicine principles translate into practical strategies for supporting long-term hair health.The conversation explores the difference between viral hair trends and clinically meaningful interventions—and why consistency, patience, and third-party testing standards matter when evaluating products in the supplement space.In this episode: What dermatologists mean when they talk about “hair health”Why hair shedding often appears 3–6 months after stress eventsHow rapid weight loss—including GLP-1–associated weight loss—can affect hair cyclesThe role hormones play in age-related thinningWhy postpartum hair shedding is normal—and temporaryHow lifestyle medicine connects sleep, stress, nutrition, and scalp biologyWhat “supplement stacking” means and why clinicians are paying closer attentionHow to evaluate whether a hair supplement is evidence-basedWhat NSF certification actually signals about supplement safetyWhy dermatologists prioritize randomized controlled trials over ingredient claimsCommon myths about rosemary oil, DIY masks, and trendy hair growth shortcutsA simple dermatologist-approved checklist for protecting hair healthTimestamps:00:00 Introduction to Dr. Heather Woolery-Lloyd02:20 Dermatology meets lifestyle medicine05:15 Navigating misinformation in the wellness content ecosystem10:45 What “hair health” actually means biologically15:45 Why hair thinning can be emotionally difficult—and clinically important19:25 The biggest myths about shedding and hair growth timelines22:45 How dermatologists evaluate supplements and clinical evidence27:00 Supplement stacking and the wellness loophole clinicians are watching32:15 DIY hair treatments vs evidence-based approaches33:30 GLP-1 medications and hair thinning explained37:40 Root causes dermatologists screen for in clinic visits41:00 A simple dermatologist’s hair health checklist44:15 Topical products and scalp-level interventions46:30 Everyday lifestyle habits that support hair growth49:25 Stress, mindfulness, and identifying delayed shedding triggers51:30 Why early evaluation matters—and why patience does tooTopics covered:Hair thinningGLP-1 medications and hair thinningPostpartum sheddingTelogen effluviumHormonal changes and agingLifestyle medicineSupplement safetyNSF for Sport certificationDermatology evidence standardsNutrition and hair biologyStress and delayed hair sheddingHair growth timelinesThis episode is part of a paid partnership with Nutrafol.
