Hair doesn't actually stop growing, but rather goes through cycles of growth and rest. Each hair follicle has a specific growth cycle, which can be affected by various factors like age, genetics, hormones, and stress. [1]
Hair growth can slow down significantly as we age, with many hair follicles stopping production of new hairs. [2] This is a natural part of aging, and while it doesn't necessarily cause hair loss, it can make hair appear thinner and less dense. [3]
Hair on different parts of the body has different growth cycles, with scalp hair typically growing longer than body hair due to its longer anagen phase (the growth phase). [6, 7] The length your hair reaches is largely determined by your genes. [7]
While hair can stop growing for a specific period during the resting phase, it can still grow again. [4] It's important to remember that the hair growth cycle is a complex process, and there are many factors that can influence it. [7]
There are various treatment options available for slow-growing hair, including medication. [1] If you're concerned about your hair growth, it's best to consult a doctor or dermatologist for personalized advice.
