Will a Delayed Session of Laser Hair Removal Affect Final Result?

We encourage our patients to try to remain on schedule for their laser hair removal treatments (every 6-8 weeks on average, but depends on body part) because we have experienced that it leads to better results.
The reason for this is that we are trying to treat the hair that will return after the treatment at a time when it is in the growth phase. At any one time, approximately 30% - 40% of your hair will be in a resting phase, meaning there is no hair in the follicle. By treating you on a defined schedule, we avoid the randomness of the hair growth cycle and treat you at a time when most of the hair should have returned after your previous treatment.
While it's not the end of the world if you are off schedule, you will receive the best results when sticking to the period defined by your practitioner.

Laser hair removal should be performed in intervals of 6 to 8 weeks to coincide with normal growth cycles of hair. If you delay treatment, it may not affect long term results, but you may need additional treatments to acheive the same results as the hair follicles will regain their strength and density.

Thanks for your question.
While it would have been more ideal to go for your laser hair removal sessions on schedule, you should be able to go now and still acheive excellent results. Hairs are in different stages of growth and shedding, and the purpose of multiple sessions of laser hair removal is to target these growing hairs. You are correct in saying that the hairs already "destroyed" will stay that way.
You may go through the last two sessions and still miss some growing hairs - it won't be because the laser didn't work, but rather because the hairs are not in the growing stage at that time to be targeted by the laser.
Good luck!
