Phases of hair regeneration - anagen, catagen and telogen - a natural growth cycle that plays a key role in both skincare and treatments such as laser hair removal.

Anagen, the phase of active hair growth, which lasts from two to six years, is crucial to the effectiveness of laser hair removal. During this period, the hair contains the highest amount of melanin, which allows the laser to effectively destroy the hair follicle by absorbing the light energy.

Catagen, which is a short transitional phase, lasts a few days and is characterised by regression of the hair follicle. Hair in this phase is less susceptible to the laser, as melanogenesis ceases and the follicle loses its connection to the blood supply.

Telogen, the resting phase, is the time when the hair falls out and new hair begins to form in the follicle. Hair in this phase is difficult to remove by laser, as the follicles are inactive.

Understanding the hair growth cycle is also important in the context of hair restoration therapies. Examples of such therapies include scalp needle mesotherapy or programmes such as Well Hair Restoration. Mesotherapy enables the precise delivery of nutrients to the skin, improving microcirculation and stimulating the hair follicles. Exosome therapies, which promote regeneration at the cellular level, are also gaining increasing importance.

Combining knowledge of the hair growth cycle with modern treatment methods enables effective care and improvement of hair health, as well as optimising the results of laser hair removal.
