In simple terms

Androgenetic alopecia, telogen effluvium, iron deficiency: identify the cause to choose the right treatment.

What you need to remember

Main Causes — Androgenetic alopecia**: the most common, hereditary, affects men and women.
Treatments According to Cause — Topical Minoxidil**: stimulates regrowth in androgenetic alopecia

Losing 50 to 100 hairs per day is physiological. Beyond that, or when density visibly decreases, it's time to consult.

Main Causes

Androgenetic alopecia: the most common, hereditary, affects men and women. Progressive miniaturization of follicles under the influence of androgens.
Telogen effluvium: diffuse and sudden hair loss 2-3 months after stress, illness, childbirth, or a strict diet.
Nutritional deficiencies: iron, zinc, vitamin D, biotin. A blood test can identify them.
Thyroid dysfunction: both hypothyroidism and hyperthyroidism can cause hair loss.
Alopecia areata: an autoimmune disease causing localized bald patches.

Treatments According to Cause

Topical Minoxidil: stimulates regrowth in androgenetic alopecia
Finasteride: blocks testosterone conversion in men
Supplementation: correction of deficiencies identified by biological assessment
PRP (platelet-rich plasma): emerging technique with encouraging results

"Miracle" food supplements generally lack solid evidence. Starting with an accurate diagnosis with a dermatologist is essential.
