The most common type of hair loss is hereditary hair loss, also known as Androgenetic Alopecia – a natural condition caused by genetics, hormone levels and the aging process.
This involves an inherited sensitisation of genetically susceptible hair follicles to dihydrotestosterone (DHT), a male hormone that can bind to receptors in hair follicles and cause them to miniaturise.
The follicles gradually shrink and the hair life-cycle shortens, resulting in thinning hair. In some cases, the follicle eventually shuts down and becomes dormant, ceasing to produce hair.
