Which area of the body is thought to have the longest telogen phase?

The back, chest, arms, and legs are areas of the body with hair that typically experience a longer telogen phase compared to other regions. The telogen phase is a part of the hair growth cycle where hair is not actively growing and is instead resting before it eventually falls out and is replaced by new hair.

In general, hair in these areas tends to have a prolonged telogen phase, which means that it remains in this state for an extended period before shedding. This longer telogen phase may be influenced by factors such as hair density, hormonal influences, and the specific function of hair in these regions, providing individuals with a greater amount of time before hair loss occurs. This is particularly relevant in discussions around laser hair removal, as understanding the growth cycles of hair can impact treatment plans and expected outcomes.

Other areas like the scalp and facial hair have different growth cycle patterns, and regions such as the hands and feet typically feature thinner and sparser hair, which also influences their telogen duration.
