Laser hair removal

Laser hair removal

(Redirected from Laser)

Laser hair removal is a method of epilation that uses laser.

Some consumers have experienced permanent hair reduction, but there is limited data on how long hair reduction usually lasts, how much hair reduction is typical, and how often permanent hair reduction occurs. Light at a specified wavelength is delivered from a handpiece into the skin, where it targets dark material (usually the pigment in hair). This is intended to cause thermal and/or mechanical damage to a hair follicle while sparing surrounding tissues.


  • Some consumers have experienced long-lasting hair removal or permanent hair reduction.
  • Considered safe if performed properly.
  • Useful for large areas such as backs or legs.
  • Regrowth can come back lighter in color or finer in texture.
  • Light-skinned consumers with dark hair have the best results.


  • Long-term data on safety and effectiveness have not been accurately established.
  • Response rates have not been established.
  • Regrowth rates have not been accurately established and cannot be predicted due to numerous variables.
  • Generally not as effective on unpigmented (gray) hairs and red or blonde hair.
  • Must be used very cautiously (if at all) on darker skin tones or on consumers who tan themselves.
  • Improper treatment can cause burns, lesions, skin discoloration lasting several months, or patchy/patterned regrowth.
  • Recent data suggest other skin structures are often affected by laser irradiation, and long term effects of this constitute an unknown risk.
  • Requires eye protection.
  • Can be expensive.
  • Some find treatment painful.
  • Regulation varies by state, so inadequate controls exist to ensure competent practitioners.
  • Some consumers, even ideal candidates, do not respond to treatment.

Due to the complicated issues surrounding this hair removal method, I have divided this into several sections. If you’re researching a specific laser type or issue, you can go right to that topic. For a more thorough review, I recommend reading the pages in order.
