how to treat a missed patch

i’m having laser hair removal on my upper body and, after my third treatment, i noticed lines of missed hair. These lines of hair grew within a week as if there were not treated. my therapist retreated these line but she also applied the laser to the area around the lines. After a month, my regrowth has come through but i have noticed there are areas where hair is not growing. These areas are where my therapist retreated me. The rest of my areas have normal regrowth subject to the usual patchiness that you expect from laser.

the problem is that i am happy with the level of hair reduction i have for my upper body (expect for those retreated areas), so what do i do. i was thinking that i could wait a long time and then have one more treatment to even out those retreated areas. not sure what the best thing is to do. i wish my therapist had only retreated the missed lines and not the areas around it. please somebody advise on the best way forward.

Laser hair removal (when it works) is notorious for leaving uneven and patchy areas. It is difficult (but not impossible) to achieve an even and consistent reduction in density. Have you discussed this issue with your therapist? Fine tuning hair density can be easily achieved with electrolysis which you might need in the future should laser efficacy plateau.

You should wait 3 weeks after each treatment and get your touchup at that point. That’s the only way you can tell what was actually missed. You need to let the hair release and shed and that takes longer than 1 week.

When they do the touchup, make sure they overlap the area by 10%, and make sure they do this at every treatment as well which avoids patchiness.
