How Laser Hair Removal Works
Laser hair removal works by sending a beam of laser light to a group of hair follicles with enough power to destroy the root, but not enough to harm the surrounding skin. This process, known as selective photothermolysis (where “photo” means light and “thermolysis” means to destroy with heat), targets hair follicles while leaving the surrounding tissues unharmed.
Laser Hair Removal vs. Electrolysis
Unlike electrolysis, which directs an electric current into each individual hair follicle (a painful and time-consuming process), laser hair removal can target a large number of hairs in one go, virtually pain-free.
Post-Treatment Process
After treatment, dead hairs will be shed over 1-3 weeks. During this period, hairs may appear to ‘grow’ as they are pushed out by new skin. After the second treatment, the area may start to look patchy, depending on your skin and hair type.
Possible Side Effects
- Redness and Bumps: The skin may be red immediately after treatment, and treated hair follicles may be raised and bumpy. This usually subsides within a few hours but can take up to 48 hours for some clients.
- Itching: A few people may experience itching a few days later as the hair is pushed out.
Treatment Schedule
Laser light targets only hair that is actively growing in the anagen phase. Therefore, multiple treatments are necessary to treat hair at other stages of growth:
- Face: Every 4 weeks
- Body: Every 6-7 weeks
The required number of treatments varies, but typically 6-8 sessions are needed for optimal results.
Session Duration
Laser hair removal sessions can take from 5 minutes to an hour, depending on the size of the area. For example, the upper lip takes about 5 minutes, whereas full legs or back could take at least 45 minutes.
Hair Growth Cycles
Hair follicles are in different growth stages at any given time. These cycles can vary between a few months and a year, which is why multiple sessions are needed to catch the hair in the anagen stage.
