Laser hair removal is a semi-permanent way to remove unwanted hair. Lasering reduces the thickness and the number of hairs present. I have never heard of threading or waxing causing an increase in hair growth. Sometimes, rubbing an area constantly can cause hair growth in that area. I have also heard of laser hair removal paradoxically causing an increase in hair growth. If there is an increase in hair growth, my suggestion would be to treat through that increase to see if the laser will ultimately do its job of reducing the thickness and the number of hairs present. We suggest that laser hair removal patients have 1-3mm of hair growth prior to laser therapy. Remember that laser hair removal only works on dark hairs (brown or black), so waxing or threading will be good treatment options for those whose hair is any other color.
