In this episode of Not Alone, Valeria sits down with board-certified dermatologist and lifestyle medicine expert Dr. Heather Woolery-Lloyd for an eye-opening conversation about hair health, supplements, stress, and what it means to take a whole-body approach to hair thinning.

From postpartum shedding to perimenopausal thinning, Dr. Heather breaks down why hair changes and why it takes time to see results. She also helps break down why so many women feel confused by the supplement space. She shares what to really look for in your supplements - from clinical trials and randomized controlled studies to third-party certifications like NSF. 

Valeria opens up about her own postpartum hair experience, and the women discuss the emotional toll hair changes can take. Dr. Heather also shares simple, actionable shifts, like five-minute meditation, daily walks, and realistic habit-building, that make wellness feel less overwhelming and more sustainable.
