Unbelievable but true! Only 10-20% of hair follicles are in the stage of active growth in humans. The rest of the hairs are at rest and are waiting for their time. Given these features of hair growth, as well as the ability of melanin (pigment) in hair and skin cells to absorb light waves, both methods work. And now in more detail.
Similarities of photoepilation and laser:
Both methods use the technique of hair removal by exposure to a light beam https://omnilase.us/. Under the action of a light wave generated by the device, light energy affects melanin in cells (including hair cells), and then is converted into heat. Due to thermal energy, the capillaries that feed the hair follicle seem to be “soldered”, cutting off the nutrition of the follicle. In the case of a laser, the follicle itself is destroyed. As a result, the “bulb” of the hair dies, and the hair remaining under the skin eventually pushes out and does not grow again.
In addition to hair removal, both devices also perform thermal stimulation of follicle growth in the dormant stage. This is necessary for the further removal of already grown hairs during the following procedures.
The need for a cycle of procedures to achieve the desired effect is both a laser and a photoepilator. Due to the fact that 80-90% of hair follicles are in the dormant stage, and photoepilation and laser hair removal only affect hair in the active growth stage, it is important, so to speak, to “awaken” the remaining hairs. After all, only after that they can be permanently deleted. It is for this reason that these hardware procedures are carried out as part of the course – 5-8 sessions. Until all of the subcutaneous hair buds are awakened and removed. The required number of sessions and the duration of the effect of the procedure depends on the individual characteristics of the patient and the type of procedure performed. Spoiler – laser hair removal is more effective in terms of duration of action.
