Laser Hair Removal Safety

Laser Hair Removal Safety

Laser hair removal is a medical procedure that uses a laser, an intense pulsating beam of light to remove unwanted hair. During laser hair removal, a laser beam passes through the skin to an individual hair follicle. The intense heat of the laser destroys the hair follicle, which prevents future hair growth. An ideal candidate for laser hair removal is a person with light skin and dark pigmented hair. Although laser hair removal effectively slows hair growth, it doesn’t guarantee permanent hair removal. It typically takes several laser hair removal treatments to provide an extended hair-free period. Periodic maintenance treatments might be needed as well.

Laser hair removal is used to remove unwanted hair. Common treatment locations include legs, back, chest, abs, underarms, upper lip, chin and bikini areas. However, it’s entirely possible to treat unwanted hair in nearly any area except the eyelid or surrounding area.

Hair color and skin type can influence the success of laser hair removal. For example, laser hair removal is most effective for people who have light skin and dark hair because the laser beam targets the pigment (melanin) in the hair. However, advances in technology have made laser hair removal an option for people who have darker skin.

Although treatment options for lighter hair continue to be investigated, laser hair removal isn’t generally very effective for white, gray, red or blond hair,

Before laser hair removal, you should schedule a consultation to learn more about the procedure. Followings are generally reviewed during the laser hair removal consultation:

  • Medical history, including medication use
  • Risks, benefits and expectations
  • Be sure to discuss a treatment plan and related costs

If you decide to go ahead and do the laser hair removal treatment you should pay close attention to the followings:

  • Limit the sun exposure especially two weeks before you treatment. Getting laser hair removal while your skin is tanned n tan can cause hyper or hypopigmentation (depending on your skin color). 
  • Avoid waxing, plucking and tweezing the hair. If you waxing, tweezing or plucking while in laser hair removal treatment can make your treatment ineffective. However you can shave at any time which will preserve the root of the hair.
  • Shave 24 hours before your treatment. This will ensure best results and lesser pain involved during the treatment.
  •  Avoid excessive sweating and irritation to the treated areas up to 24 hours after the treatment.
  •  Apply plenty of sunscreen preferably SPF 30 or higher to the treated area after the treatment.


For best results, you may need up to six treatments spaced six weeks apart. Additional periodic maintenance or touch up treatments may be required on an annual basis to keep the hairs off.

Effective Laser Hair Removal

Does Laser Hair Removal Work?

Yes. Laser hair removal definitely works, but it works best on dark hairs on a light background and very little on white or red hairs. The laser needs the pigmentation on dark hair as a target, and the lighter the surrounding skin is, the easier it is for the laser to treat without damaging the area around. So dark hair on dark skin may require additional treatments for an absolute best results.

The most effective treatments happen when the hair has pigmentation (colEffective r) and the hair is in active growth state. Multiple treatments are required and are usually spaced anywhere from 4-8 weeks apart.  Each body part has a different growth rate; therefore, if you are treating multiple areas you many need to stagger appointments to capture that optimum growth state.

Hair can only be treated if it is actively growing and somewhere close to the surface of the skin.  If the full shaft of the hair is removed prior to treatment by waxing, tweezing or plucking there is no conduit for the laser light to reach the hair root.  Shaving or trimming is the best way to maintain active hair growth. As we age different hair follicles will mature and produce hair.  Hormonal changes will also aggravate this process to some extend.  If your hormones are fluctuating and change on a regular basis just be aware that you may need touch up treatments throughout your life time.

Additionally, not all lasers and facilities are created equally.  There is not a one size fits all method of treatment.  Lasers come in all different wave lengths.  Depending on your skin type and hair color one may be better for you than another. Lasers are very powerful and potent and can cause damage. Be sure that your technician has experience and knows the capabilities of the laser that they are using.
