How does laser hair removal work?

Laser hair removal works by directing concentrated light (ie laser) at the pigment in the hair follicles. The light energy is absorbed by the melanin (pigment), which converts it into heat. This heat damages the hair follicle which stops its ability to produce new hair. Over time, with repeated treatments, hair growth in the targeted area is highly reduced. 

Can laser hair removal cause cancer?

There is no evidence to suggest that laser hair removal causes cancer. The lasers used in hair removal are specifically designed to target hair follicles and do not penetrate deeply enough into the skin to affect other tissues or cells. Laser hair removal equipment is regulated and deemed safe for cosmetic use.

How many sessions do you need for laser hair removal?

Most people require between 6 to 8 sessions for optimal results. Hair grows in cycles, and laser hair removal is most effective during the active growth phase.

The number of sessions required can vary depending on individual skin type, hair colour, and the certain area being treated.

Can you have laser hair removal while pregnant?

How long do you need between laser hair removal sessions?

We recommend a 4 to 6-week gap between laser hair removal sessions. This allows time for hair to enter the active growth phase, which is when the treatment is most effective. The exact duration may vary based on the treatment area and individual hair growth patterns, so it’s important to follow your clinic’s recommendations for timing.

How to prepare for laser hair removal?

To prepare for laser hair removal, avoid sun exposure and tanning (including fake tan) for at least 2 weeks prior to your session. Don’t be tempted to wax, pluck, or use hair removal creams as they remove the hair follicle that is needed for the laser to target. Shaving is fine and will usually be recommended 24 hours before the session to ensure the laser targets the hair root, not the actual hair. You should also avoid using any skincare products that contain retinoids or acids in the treatment area in the days leading up to your session.

Does laser hair removal work on blonde hair?

Laser hair removal is less effective on blonde, grey, or very light-coloured hair. This is because the laser targets the melanin (pigment) in the hair, and lighter hair contains less melanin. Some advanced laser technologies have improved results for individuals with lighter hair, but the effectiveness will still be reduced compared to darker hair.

How often can you get laser hair removal?
