Why Crash Diets Trigger Severe Hair Fall
Rapid weight loss may look rewarding on the scale, but it often comes at a cost. One of the most common complaints after dieting is sudden and excessive hair fall. Hair fall after dieting is a well known medical reaction to nutritional shock.
This blog explains why crash diets cause hair loss, how long it lasts, and how to reverse diet related hair fall safely.
Why Crash Diets Affect Hair So Quickly
Crash diets drastically reduce calories, protein, iron, and essential vitamins. The body enters survival mode and diverts nutrients away from hair follicles.
Medical term: telogen effluvium. In simple words, sudden nutritional stress pushes hair into the shedding phase.
How Hair Fall After Dieting Happens
Protein And Calorie Deficit
Low calorie intake reduces protein availability. Hair growth slows and existing hair sheds rapidly.
Vitamin And Mineral Deficiency
Crash diets often cause iron, zinc, and B vitamin deficiency, weakening hair roots.
Hormonal Stress Response
Sudden weight loss increases stress hormones, worsening hair fall after dieting.
How Long Does Diet Related Hair Fall Last
Hair fall usually starts two to three months after crash dieting. Without correction, shedding may continue for several months.
