Why can chronic stress result in hair loss? New research provides clues
Fox News
It’s well known that chronic stress can lead to hair loss, but how exactly stress causes hair loss has been a mystery — until now. A new study conducted by researchers at Harvard University may provide a clue.
First, it’s important to understand the three stages of hair growth: growth, rest and degeneration. In the first state, hair follicle cells are activated and hair is continually produced, in the second, the hair stays in a state of rest but can still shed, and in the last stage — degeneration — hair falls out. "During the resting phase, the stem cells are quiescent and hairs shed more easily. Hair loss can occur if the hairs shed and the stem cells remain quiescent without regenerating new tissue," explains an accompanying press release on the study’s findings.More Related News
