In order to better understand how diode laser hair removal machine achieves the most effective results, it is necessary to understand the hair growth cycle.
The hair growth cycle consists of three phases:
Growth period (growth period), transition period (Catagen), dormant period (Telogen)
Anagen is the active growth phase of hair follicles. The cells in the roots of the hair divide rapidly and extend to the hair shaft. Hair follicles are most susceptible to lasers during the long-term period of hair growth because they are rich in protein (keratinocytes) and melanin. The long-term duration of hair follicle hair is genetically determined. About 85% of the hair follicles in our body are in the hair for a long time and may last for about 2-6 years. In the early stages of anagen, the hair follicles enter the mid-hair growth phase.
During the degenerative phase, the hair stops growing and remains only 2-3 weeks at this stage before entering the next stage. At any given time, approximately 5% of the hair is at this stage.
The next stage is when the hair begins to fall off and the hair begins to circulate for a long time while stimulating the follicle to begin a new cycle. For healthy hair follicles on the scalp, the length of this stage is approximately 100 days, but there may be significant differences in hair from other parts of the body. At any given time, approximately 10% of the hair follicles are in a resting period.
Now we know that the initial stage of hair growth is the most important stage of laser hair removal machine. The results of a single laser hair removal process are highly dependent on the amount of hair in the treatment area during the growth phase. This is why multiple laser hair removal treatments are needed to achieve the desired results, as the hair follicles in a single area may be in different stages of growth.
