Laser hair removal is one of the most popular non-surgical cosmetic procedures for reducing unwanted hair on different areas of the face and body.
The treatment uses concentrated light energy that is absorbed by the pigment (melanin) in the hair, generating heat that targets the hair follicle and gradually reduces its ability to produce new hair.
Results vary from person to person depending on hair colour and thickness, skin tone, treatment area, laser technology, and hormonal factors.
The American Academy of Dermatology (AAD) notes that laser hair removal can be safely performed on different skin tones when the appropriate technology and settings are selected, and stresses the importance of choosing a practitioner experienced with the patient's skin type.
Areas for Laser Hair Removal
Laser hair removal can be performed on most areas of the body, including:
- The face, particularly the upper lip and chin.
- Underarms.
- Arms and legs.
- Bikini area.
- Back and chest.
- Neck and shoulders.
The appropriate treatment areas are determined during the initial consultation based on the patient's hair characteristics, skin type, and treatment goals.
Benefits of Laser Hair Removal
The main benefits of laser hair removal include:
- Long-term reduction in unwanted hair growth
- Less reliance on shaving and waxing
- Helping reduce razor burn and ingrown hairs in some patients
- The ability to treat relatively large areas during a session
- Little to no downtime in most cases
After a series of treatments, regrowth is generally less noticeable, with hairs becoming finer and lighter in many patients.
Factors That Affect the Results
The effectiveness of laser hair removal depends on several factors, including hair color and thickness, skin tone, treatment area, laser type, device settings, and adherence to the recommended treatment schedule.
Hormonal factors can also influence results, particularly when treating facial hair in women. This may mean that maintenance sessions are required over time.
Before and After Laser Hair Removal
Before the Session
- Avoid direct sun exposure and tanning
- Inform your dermatologist or practitioner about any medications or skincare products you are using
- Avoid waxing or plucking the hair from the root before treatment according to your clinic's instructions
- Follow all preparation instructions provided during your consultation
After the Session
- Avoid direct sun exposure and use an appropriate broad-spectrum sunscreen.
- Avoid rubbing or irritating the treated area.
- Apply a cool compress if mild redness or swelling occurs.
- Follow the aftercare instructions provided by your healthcare professional.
Mild redness and swelling can occur after treatment and usually last around one to three days.
More serious complications, including burns, pigmentation changes, and scarring, are uncommon but can occur, particularly when laser treatment is performed incorrectly or by an inexperienced practitioner.
Frequently Asked Questions
How Many Sessions Are Needed for the Best Results?
The number of sessions varies from one patient to another.
Many patients require 2–6 treatments to achieve a noticeable reduction in hair growth, while the AAD notes that laser hair removal may require 6 or more sessions for effective treatment in many cases. The exact number and interval between sessions depend on how the hair responds to treatment.
According to the AAD, some patients may experience approximately 10% to 25% hair reduction after the first treatment, although individual results vary.
How Long Do Laser Hair Removal Results Last?
Many patients remain free of noticeable hair for months or even years after completing a treatment course. However, some regrowth can occur over time. When hair returns, it is often finer and less noticeable, and some patients may require maintenance laser treatments to maintain their results.
