How Laser Hair Removal Works: Science, Hair Growth Cycles & Technology
At Dermacarelab, we believe that understanding the science behind laser hair removal helps clients feel confident and informed before starting treatment. Laser hair removal works by using concentrated light energy to target melanin (pigment) present in the hair shaft. This light converts into heat, which damages the hair follicle and slows future hair growth without harming the surrounding skin.
The Science Behind Laser Hair Removal
Laser technology is designed to selectively target dark hair while keeping the skin safe. The laser energy travels down the hair shaft and reaches the follicle, weakening its ability to produce new hair. Over time and multiple sessions, hair growth becomes finer, lighter, and significantly reduced.
Understanding Hair Growth Cycles
Hair grows in three main phases—anagen (active growth), catagen (transition), and telogen (resting). Laser hair removal is most effective during the anagen phase because the hair is directly connected to the follicle. Since not all hair grows at the same time, multiple sessions are required to treat each cycle effectively.
Technology Used at Dermacarelab
Dermacarelab uses advanced, FDA-approved laser systems that ensure precision, safety, and comfort. These technologies are suitable for different skin tones and hair types, delivering consistent and long-lasting results when performed by trained professionals.
