How does stress cause hair loss?

Stress triggers the release of cortisol, a hormone that can disrupt the healthy hair growth cycle.

It’s normal for hair to fall out and grow back in cycles. However, high cortisol levels can cause hair to fall out too soon, and it can slow or stop new hair growth. This often leads to hair thinning.

It typically takes weeks or months of chronic stress before you’ll see effects on your hair. If you’re experiencing ongoing stress and hair loss, stress management strategies may help restore your natural hair growth cycle. You can also try treatments that promote hair follicle health.
