One of the most common conditions that affect women is Female Pattern Hair Loss, or Androgenetic Alopecia.
This hereditary condition causes thinning hair which can be found around the top of the head and/or the crown area, whilst the density of the hair from the sides and back of the scalp will remain unaffected.
You may notice you start to shed more hair than usual, and your parting becomes wider.
Female hair loss can also cause a receding hairline, where hair thins around the temples.
