Is my Thyroid connected to my hair?

  1. Hair starts growing at the root in the bottom of your hair follicle on your scalp.
  2. Your scalp’s blood vessels feed the root, creating more cells and making your hair grow.
  3. Hair pushes up and out through your skin. It passes through oil glands that help keep it soft and shiny.
  4. Hair grows for a while but then falls out as each new regrowth cycle begins.


When hormone production is disrupted, specifically of hormones T3 and T4, it affects other processes in the body. This includes the development of hair at the root. Hair falls out and may not be replaced by new growth, resulting in thinning across your scalp and other areas such as your eyebrows. Changing your diet and stress level could lead to your fix however please consult your Doctor.
