If I miss the hair removal schedule and go late, will it be ineffective?

The laser only reacts to hair in the growth phase, so it is important to receive treatment during the 4 to 6 week timing when the hair that was in the rest phase from the last treatment transitions to the growth phase. If you miss this timing, that hair may revert to the regression or rest phase, resulting in reduced effectiveness. Therefore, adhering to the specified schedule helps minimize the number of sessions.
