Iron, Vitamin D, B12 and Zinc: Which Deficiencies Cause Hair Loss?
Which deficiencies are linked to hair fall, which tests show them, why supplements without a test can backfire, and how long regrowth takes.
Articles on hair loss, transplants, PRP and beard restoration — written for patients, medically reviewed before publication, and honest about what treatment can and cannot do. No miracle cures, no guaranteed results, no borrowed photographs.

Which deficiencies are linked to hair fall, which tests show them, why supplements without a test can backfire, and how long regrowth takes.

Why shedding often starts a few months after childbirth, how long it usually lasts, treatment questions while breastfeeding, and when to get it checked.

How flaking, itch and scratching relate to shedding, when the two are separate problems, and how dandruff is treated so it stays controlled.

What the studies on rosemary oil, onion juice and oiling actually show, where home remedies can irritate the scalp, and when to stop and get assessed.

Genes, B12, thyroid, smoking and vitiligo: what drives early greying, which tests are worth doing, and what can and cannot reverse it.

Borewell water damages hair shafts; it does not cause pattern baldness. What hard water, pollution and monsoon shedding really do, and when to stop blaming the tap.
Why this blog starts small
There are around 370 articles on the old site. Rather than carry them across untouched, each one is being checked against twelve months of Search Console data and bucketed: keep and refresh, merge into a stronger article, or remove. Roughly half of any large blog estate typically merges or prunes — and a smaller set of genuinely useful articles outperforms a large set of thin ones. New posts appear here as that audit completes.
Start here instead
The treatment pages carry the procedure detail, recovery timelines, risks and costs. The blog is for the background reading around them.
