• Laser Hair Removal - How Does It Work?
How Does Laser Hair Removal Work?
When the laser flashes, it emits both light and heat energy. The light is attracted to, and is absorbed by, the pigment in the hair follicle. (ideally coarse, dark brown or black hair) This energy is transformed into heat, which damages the root of the hair but not the surrounding tissue. After repeated sessions, the hair follicle will be unable to regrow hair as the blood supply will have been coagulated. The lighter the skin colour, and the darker the hair, the better. Since light colours reflect more energy than they absorb, and dark skin (due to natural pigment or tanning etc) absorbs more energy than it reflects, it only stands to reason that most light skinned, dark haired individuals are ideal candidates for laser hair removal. But this doesn’t mean that people with darker skin can’t have laser hair removal! Quite the contrary. This is precisely why we use multiple lasers in our facilities. When it comes to lasers, one size does not fit all. Different lasers, with different parameters are required to effectively treat darker skin, up to Fitzpatrick Skin Type VI in some cases. And yes, certain precautions must be taken. The skill of the laser technician is imperative when treating dark skin so as not to cause trauma to the surrounding tissue, such as transitory pigmentary changes or Keloid scarring. There are only four times in a year when the root of any hair can be destroyed by any permanent hair removal syste |
m. And that includes Laser. Our hair goes through three stages of growth; these stages being: Anagen-Growth phase, Catagen-Inactive phase & Telogen-Dormant phase, every 12-14 weeks for a great percentage of face & body hair.
