Hair loss happens when the scalp stops receiving chemical signals telling it to create new hair from existing follicles. When this happens, the follicles shrink and eventually close, making it impossible for new hair to grow. Even if hair grows back, it usually becomes thinner, wispier, or of a coarser, less dependable quality.Unnatural hair loss can occur as a result of disorders like androgenetic alopecia. Hair loss is frequently caused by this, as well as other hereditary diseases (such as basic baldness).Medication, hormone changes, or a simple hereditary tendency are some of the other possibilities.The issue with baldness and thinning hair is that you are born with all of your hair follicles. You lose 50 to 100 hairs per day, so if you don’t replace them, thinning will happen quickly.
