Reading Time: <1 minuteCurrently, I am being asked by a certain manufacturer to provide theoretical consulting on the development of hair removal equipment.It seems that the general public hardly understands the difference between hair removal at a beauty salon and medical hair removal.Laser hair removal is not allowed in beauty salons.For medical hair removal, there was a time when optical hair removal called IPL was used, but now laser hair removal has become mainstream. Hair removal equipment that adds RF energy to IPL is highly effective, has been used clinically for many years, and is still my favorite.Hair removal equipment has been developed on a theoretical basis.It aims for long-term hair removal effects by destroying the so-called hair center.In the past, the center of hair growth was called the dermal papilla, but it has now become clear that stem cells in the bulge area play a very important role in hair growth.In other words, the hair removal effect cannot be obtained unless the bulge area is thoroughly destroyed with heat energy.I have summarized the knowledge and papers in the bulge area. bulge area The bulge region is a newly discovered organ through recent research.It has the function of promoting hair growth by sending instructions to the dermal papilla, which produces hair.The new theory of medical laser hair removal is that permanent hair removal can be achieved without destroying the hair matrix cells or dermal papilla, which are the seeds of the hair, as long as the bulge area is destroyed and the command for hair growth is cut off. Until now, hair matrix cells (hair roots) have been destroyed.Medical laser hair removalIt was said to have the effect ofHowever, recent research has revealed that it is also important to destroy the bulge region, a hair growth factor that nourishes hair matrix cells.What is the bulge region?alopecia treatmentA type of stem cell (cell that produces cells) that was discovered in 2000 to 2001 as part of research on hair.Hair growth factors produced from the bulge region become hair matrix cells, which receive nutrients from the dermal papilla to generate hair.TraditionalMedical laser hair removalBecause the aim was to destroy the hair matrix cells, the bulge area was also destroyed at the same time.However, in recent years, hair removal machines that destroy only the bulge area have also appeared.destroy hair matrix cellsMedical laser hair removalThe heat was destroying the dermal papilla through the black hair.Since hair in the growing stage is connected to the dermal papilla, it was possible to thermally destroy the dermal papilla if there was black hair.However, the bulge area is not connected to the hair and always exists in the dermis.In other words, whether or not there are hairs is theoretically irrelevant to destroying the bulge area.However, the mechanism of the currently used hair removal machines that target the bulge area remains the same: they react to the black melanin pigment and apply heat.Therefore, even if the method destroys the bulge area, hair removal is performed in accordance with the hair replacement cycle.   Bulge region related papers 1: 2: 3: 4: XNUMX: XNUMX: 1: file:///C:/Users/NOBUHI~1204/AppData/Local/Temp/XNUMXA_Abstract.pdf XNUMX: XNUMX: XNUMX: XNUMX:   For cosmetic surgery, cosmetic surgery, armpit treatment, hyperhidrosis treatment, petite plastic surgery, hokuro removal, scar treatment, wrinkle, and sagging treatment in Nagoya, please contact Sakae Clinic.
