Hair is one the most nutrient demanding tissues in the body.
Hair is often a reflection of our nutrient status. If you’re noticing it fall out in clumps in the shower and have been told that everything is “normal” you’re not alone. You deserve answers and the correct testing.
Women's Hair Loss & Hair Health
Losing your hair as a woman is uniquely disorienting, because almost nobody around you expects it or takes it seriously the way they would a man's hairline receding. If you've been told to "just wait it out" or "it's probably just stress," I want you to know there is almost always a mechanism, and it's usually findable.
Featured: Peer-Reviewed Research
I'm proud to be a co-author on a 2026 peer-reviewed clinical study published in Dermatology and Therapy, one of the only published trials to objectively measure linear hair growth rate in women using targeted hair-growth nutraceuticals across 180 participants over six months. This is the kind of evidence-based approach I bring into the exam room: not just clinical experience, but published, peer-reviewed research on what actually moves the needle for women's hair growth.
Female Pattern Hair Loss
Female pattern hair loss shows up as diffuse thinning, often most noticeable at the part line and crown, rather than the receding hairline pattern typical in men. It's driven by a combination of genetics, androgens, and age-related hormone shifts, and it's treatable when addressed early.
Telogen Effluvium
Telogen effluvium is a temporary but often dramatic shedding, usually appearing two to four months after a triggering event: illness, extreme stress, rapid weight loss, childbirth, or a major nutrient deficiency. The strands of hair you find everywhere are a real, physical response to something your body just went through, and identifying that trigger matters for how we treat it.
PCOS and Hair Loss
Elevated androgens from PCOS can miniaturize hair follicles on the scalp while simultaneously increasing hair growth elsewhere on the body. If you're dealing with both scalp thinning and unwanted facial or body hair, PCOS is one of the first things I look at.
Thyroid and Hair Loss
Thyroid dysfunction, both under- and overactive, is a well-documented cause of diffuse hair thinning, and it's routinely under-tested because most panels only check TSH. Hair loss combined with fatigue, cold intolerance, or weight changes is a strong signal to look here.
Iron and Ferritin
Ferritin sitting at the very bottom of the "normal" range is often still too low to support healthy hair growth, even though it won't get flagged on a standard lab report. This is one of the most common, most fixable causes of hair loss I see, and it's frequently missed entirely.
Nutritional Factors
Beyond iron, deficiencies in zinc, biotin, vitamin D, and protein intake can all contribute to hair thinning. Crash dieting or chronic under-eating is a common, overlooked driver, especially in women trying hard to "eat healthy."
Hormones
Beyond androgens and thyroid, shifts in estrogen, particularly postpartum and during perimenopause, can trigger noticeable hair changes as your follicles respond to a rapidly changing hormonal environment.
Stress
Chronic stress affects hair growth both directly, by pushing follicles into a shedding phase, and indirectly, through its impact on cortisol, thyroid function, and nutrient absorption.
Gut Health
An inflamed or imbalanced gut can impair nutrient absorption, meaning even a good diet might not be reaching your follicles the way it should. Gut health is an underappreciated piece of the hair loss puzzle.
Scalp Health
A healthy scalp environment, free of excess inflammation, buildup, or microbial imbalance, is the literal foundation hair grows from. Scalp health is often overlooked in favor of focusing only on internal causes, but it deserves its own attention.
Hair loss deserves the same rigorous, root-cause approach as any other health concern, backed by real testing and real research, not guesswork. Book a free 10-minute discovery call and let's find out what's actually driving yours.
Frequently Asked Hair Loss Questions
-
The most common causes include androgens (as in female pattern hair loss and PCOS), thyroid dysfunction, iron/ferritin deficiency, telogen effluvium from a triggering event, nutritional deficiencies, and chronic stress. Often more than one factor is involved.
-
Yes. Androgens, thyroid hormones, estrogen shifts (postpartum, perimenopause), and PCOS/PMOS are all established causes of hair thinning and shedding in women.
-
Telogen effluvium is a temporary, diffuse shedding triggered by a specific event (illness, stress, postpartum) that typically resolves once the underlying trigger is addressed. Female pattern hair loss is a more gradual, progressive thinning driven by genetics and hormones, usually concentrated at the part line and crown.
-
A thorough workup typically includes ferritin (not just iron), a full thyroid panel (TSH, free T3, free T4, antibodies), vitamins, micronutrients, hormones and possibly other root cause testing depending on history.
-
Indirectly, yes. Poor gut health can impair absorption of the nutrients (iron, zinc, biotin, protein) that hair follicles need to function properly.
