Why is your hair suddenly thinning, shedding or breaking? Board-certified dermatologist and Chief Medical Advisor at Nutrafol, Dr. Heather Woolery-Lloyd, joins Dr. Thaïs Aliabadi and Mary Alice Haney for a deep dive into the many different reasons women experience hair thinning and why figuring out the cause matters before choosing an approach that’s right for them. We break down everything from stress-related shedding and postpartum hair thinning, perimenopause and menopause to nutritional gaps, tight hairstyles, extensions, heat and chemical damage. Dr. Woolery-Lloyd also explains why hair shedding may not show up until 3 to 6 months after a stressful event and why something that happened months ago, including surgery, childbirth, a major move, divorce or rapid weight loss, may be connected to what you are seeing in the shower today. We also discuss hair thinning associated with GLP-1 medications and why rapid or significant weight loss, reduced protein intake, and nutritional deficiencies may be more important factors than the medication itself. Plus, we get into minoxidil, spironolactone, PRP, light therapy, hair supplements, protein, iron, vitamin D and what actually deserves a place in a hair growth plan. If your part is getting wider, your ponytail feels thinner, or your shower drain suddenly is seeing more of a build up of hair , this episode will help you understand where to start. #NutrafolPartner This episode is brought to you by Nutrafol.

Stress-related shedding, hormonal changes, PCOS, nutritional deficiencies, thyroid disease, autoimmune conditions, and mechanical or chemical damage can all affect hair. Identifying the underlying cause is essential because treatments vary depending on the type of hair loss.Hair shedding can appear months after a stressful event. Telogen effluvium occurs when a greater proportion of hair follicles shifts out of the active growth phase and into the resting phase. Shedding may become noticeable three to six months after childbirth, surgery, illness, or significant emotional stress.Hormonal changes can affect both hair growth and hair quality. Estrogen supports the active growth phase of hair, while declining estrogen during perimenopause and menopause can contribute to thinning in susceptible women. Hair can also become drier, more fragile, and more prone to breakage with age.GLP-1-associated hair shedding may be related to weight loss and nutrition. The discussion highlights rapid or significant weight loss, inadequate protein intake, and micronutrient deficiencies as potential contributors. Anyone experiencing hair loss while taking a GLP-1 medication should consult their healthcare provider rather than stopping or changing treatment independently.Tight hairstyles can cause preventable hair loss. Repeated tension from tight ponytails, braids, extensions, and other styling practices can lead to traction alopecia, often affecting the frontal hairline. Reducing tension early may help prevent lasting damage.Hair breakage and hair shedding are not the same. Shedding involves hairs leaving the growth cycle, while breakage occurs when the hair shaft becomes damaged. Heat, chemical treatments, UV exposure, and excessive pulling or manipulation can weaken hair and increase breakage.A thorough evaluation can help uncover underlying conditions. A dermatologist may review recent stressors, family history, menstrual patterns, medications, and hair care practices, along with examining the scalp. Depending on the individual, testing may include thyroid function, blood counts, iron and ferritin, vitamin D, and other targeted laboratory tests.Treatment should be tailored to the cause. Depending on the diagnosis, options may include topical or oral minoxidil, anti-inflammatory treatments, light therapy, PRP, nutritional support, or other prescription therapies. Not every treatment is appropriate for every person, so individualized medical guidance matters.Choose supplements based on evidence and safety. Dr. Heather recommends looking for clinical studies on the finished product rather than relying on individual ingredients alone. Independent quality and safety certifications can also help consumers evaluate supplement standards.Hair regrowth takes time. Reduced shedding may take around three months to become noticeable, while significant regrowth can take six months or longer. Products promising dramatic results within just a few weeks should be approached with skepticism.A balanced diet supports healthy hair. Adequate protein, fruits, vegetables, and sufficient vitamins and minerals are important considerations. Addressing a confirmed deficiency may be part of a broader treatment plan, but there is no single food or supplement that works for every cause of hair loss.Seek help early and give yourself grace. A widening part, a noticeably thinner ponytail, bald patches, or persistent changes in shedding are worth discussing with a healthcare professional. Early evaluation can help identify treatable causes, and hair changes should be approached with patience rather than self-blame.
