Hair loss in young women

  • There are two main causes of hair loss in a female in her 20s:
  1. Genetic hair loss. About 10% of women start to develop hair loss in their 20s. The key feature is worsening hair loss in the centre of the scalp and progressive "miniaturization" of hairs. 
  2. Telogen effluvium (hair shedding). About 30 % of women under 30 have low iron. This can sometimes cause hair loss 
Other causes of hair loss are possible to - so if you are worried see a dermatologist. Low thyroid levels, hairstyles, excessive heat, illnesses, dieting, high stress can all give hair loss.

At minimum, most would recommend a few simple blood tests and a detailed scalp examination.
