The removal of unwanted hair is a traditional and old practice which has been a part of human history. As technology makes progress with passing time, the advanced and refined hair-removal
techniques are introduced in the society such as threading, laser hair removal, and electrolysis. Along with this advancement, the doctors
are also getting advanced and well versed with upgraded technology. The doctors understand the hair growth patterns and give treatment accordingly.
Hair Growth Cycles
The hair growth takes place in three repeating phase which are: anagen (hair growth), catagen(follicle transformation), and telogen (the resting/shedding period). During anagen, the hair follicle emerges from its pore while oil is produced by sebaceous glands to protect and condition hair. During catagen, the shrinkage of hair follicle takes place because a part of it is destroyed and the dermal papilla breaks away to rest and rejuvenate.
This phase can last anywhere from two to three weeks. During telogen, the hair remains in the follicle for about three months and is gradually shed during exogen. The anagen cycle is considered as the ideal phase for removing hair because the hair shows an active growth from the bulb and is rooted deep in the follicle.
In this stage, certain hair removal
techniques may even be able to remove the bulb as well. Hairs that emerge a few days after hair removal
are in the anagen stage and either had not reached the surface of the skin at the time of the treatment or were not long enough to be removed.
As it is well versed that the hair growth takes place in stages. The laser hair removal
process targets that hair follicles which are in the active growth stage. The laser is moved over the affected area so as to destroy the hair follicles present over there.
There is wide variety of lasers available and the doctor will make a decision as to which laser will suit the person’s need. Because the laser
only destroys hair follicles that are in the active growth stage and hair grows in stages so multiple treatment is required to completely remove unwanted hair.
Spreading out the treatments every 4-8 weeks allows for the laser to destroy the hair as it grows in cycles. Most patients need 3-5 treatments total.
