TRICHOGRAM

Control of the Hair Growth Cycle is of great importance because the majority of patients with hair pathologies experience issues due to disruptions in the hair growth cycle. Human hair goes through three phases of development: anagen – the growth phase, catagen – the regression phase, and telogen – the resting phase, which is followed by a new anagen phase, repeating throughout a person’s life. Each hair follicle is genetically programmed to produce 25-27 hairs, and each hair has its own “individual plan” for life, so different hair shafts are in different stages of the growth cycle at any given time.

Shortening of the anagen phase and the early onset of the catagen phase lead to common hair loss pathologies such as androgenetic alopecia, alopecia areata, telogen effluvium, and others. During these conditions, there is an increase in the number of hair follicles in the telogen phase (by 20% or more), which is confirmed through laboratory trichogram analysis.

Trichogram is a microscopic examination method used to objectively study the stages of hair growth. Through a trichogram, we can determine the percentage ratio of hairs in the anagen (growth) and telogen (shedding) phases. The trichogram allows us to identify the type of alopecia, monitor the dynamics of hair loss, and evaluate the effectiveness of the treatment provided.
