Why Does Hair Get Thinner?
- The degree of thinning that an individual experiences can vary due to both external factors and internal factors. Examples of external factors would be stress, exposure to free radicals and UV rays. Examples of internal factors would be genetics and follicle sensitivity to the hormone Dihydrotestosterone, or D.H.T.
- Androgenetic Alopecia, or "pattern baldness", occurs in both men & women whose hair follicles are sensitive to D.H.T. (a primary cause of thinning hair & hair loss).
- Typically, hair on the top and front of the head is most sensitive to D.H.T. Over time, this hair will become weaker, finer, & may eventually stop growing.
