Hair fall after 25: hormones, iron, or stress?

Diffuse thinning usually points to iron, thyroid or stress. Thinning at the crown with a widening part is androgen-driven — common with PCOS.

Get these checked

Ferritin (aim above 50), TSH, vitamin D and free testosterone.

What supports regrowth

Biotin and zinc for the shaft, D3 for the follicle cycle. Regrowth takes 3–4 months to show.
