We know that hair has a growth phase, a regression phase, and a resting phase. During laser hair removal, we can effectively remove hair in the growth phase and some of the hair in the regression phase. However, the hair in the resting phase will not be affected by laser hair removal, and we need to wait until it enters the growth phase again before removing it. So how often should we do laser hair removal?
How often should laser hair removal be done?
Laser hair removal is usually done every 4 weeks. This is because the hair growth cycle is approximately 3-4 weeks, and we determine the timing of the next laser hair removal session based on the hair growth cycle. The specific timing should be consulted with a doctor based on individual differences.
Criteria for repeating laser hair removal
The growth of body hair varies from person to person. Generally, we say that laser hair removal can be done again when new hair grows on the surface of the skin after a previous session.
Different intervals for laser hair removal on different body parts
The growth rate of hair on different parts of the body varies. The hair on the lips grows slower, while the hair on the armpits and limbs grows faster. Therefore, the interval for laser hair removal on the lips should be longer, while the interval for the armpits and limbs can be shorter.
How many sessions of laser hair removal are needed for effectiveness?
At least 2 sessions of laser hair removal are needed to see the effect. If permanent hair removal is desired, it may require 4-6 repeated sessions of laser hair removal. With a one-month interval between sessions, it would take at least one month to truly see the hair removal effect.
