A vast majority of hair loss cases are due to an undesired alteration in the natural hair growth cycle. Several known factors influence hair loss, including genetics, hormones, illness, medications, and lifestyle.
Any of these underlying factors may alter hair follicle cycling, resulting in a shorter anagen phase, delayed anagen phase, or hair thinning caused by follicular miniaturization.
While we may not have control over factors like our genetics— lifestyle, a key contributor to hair loss is within our control.
