Pain

• Though laser hair removal is fairly painless, the fact is that it doesn't tickle. Every hair removal specialist uses a different technique to cool the area to be treated, but some discomfort should be expected.
  
  

Itching and burning

• Lasers are powerful energy transmitters and do cause a bit of localized burning. The effect is not dissimilar to a slight sunburn or heat rash and should disappear within three days.
  
  

Hair loss

• Laser hair removal is not instantaneous. This technique simply kills the hair follicle; it may take several weeks for the hair to fall out.
  
  

Discoloration

• Choosing a technician with the most up-to-date training and equipment is essential, since older lasers are known to cause skin lightening or darkening.
  
  

Regrowth

• Laser hair removal is not permanent on most individuals, and some hair regrowth is to be expected within 3-5 months of treatment.
