Hair loss is the scalp expressing what is happening systemically, not a scalp problem.
Hair follicles are among the most metabolically active structures in the body, requiring a constant supply of hormonal signals, nutritional substrates, and circulatory support to maintain normal growth cycle function. When any of these is disrupted, the growth cycle shortens, follicles miniaturise, and hair loss results. The follicle itself is not the problem. The systemic environment supporting it is.
Androgenic hair loss in women, driven by elevated androgens from insulin resistance and PCOS, is the most common pattern. Iron deficiency is the most commonly missed nutritional cause, ferritin below 70 ng/mL can impair hair growth even when haemoglobin is normal. Thyroid dysfunction alters the hair growth cycle directly. Autoimmune activity produces alopecia areata. Each produces a distinct pattern that assessment identifies and maps to a specific care plan.
Conditions that commonly cause hair loss.
Female hair loss has several distinct causes that require different approaches. Assessment identifies the specific pattern and its primary contributors.
