At Center for Dermatology & Laser Surgery, we answer a lot of questions regarding our laser hair removal service and one of the top questions we get is “How long does laser hair removal last?”

Most are glad to learn that laser hair removal is a long-term solution that permanently stops hair from growing from the treated hair follicles.

How Long Does Laser Hair Removal Last?

For some people, laser hair removal lasts for months or even years. In fact, some people report no hair growth on treated areas after 10 years.

Is Laser Hair Removal Permanent?

Laser hair removal damages and destroys hair follicles, which are the tunnel-shaped structures that produce hair. Once the follicles are destroyed, they do not produce hairs. For these follicles, hair removal is permanent.

Damaged follicles can still produce hair, but at a slower rate. The hairs are also finer and sparser, so they are less noticeable. Multiple treatments are necessary to destroy the hair follicles and provide long-term hair removal. The number of treatments required to create permanent hair removal depend on a number of factors, such as:

    • Density of hair
    • Color of hair
    • Color of skin
    • Texture of hair
    • Hair growth cycle

Am I a Good Candidate for Laser Hair Removal?

You are a good candidate for laser hair removal if your unwanted hair is course and dark, as lasers are attracted to pigment in hair so they work best on hair that is brunette or darker. If you have blonde, red, or gray body hair, you may not achieve the desired results immediately. Fortunately, undergoing repeat laser hair removal sessions can help you remove unwanted hair.

You may also be a good candidate for laser hair removal if you want to remove hair from specific areas of your body. While laser hair removal can remove hair from any part of the body you wish, the procedure is especially effective on the bikini, underarm, chin and lip areas.

How to Prepare for Laser Hair Removal

Preparing for laser hair removal is important for optimal results. To prepare for laser hair removal, be sure to:

    • Avoid sun exposure and, whenever you must go out into the sun, apply a broad-spectrum, SPF30 sunscreen
    • Do not use any sunless skin creams that darken your skin
    • Use any skin lightening products or skin bleaching creams provided by your dermatologist
    • Avoid other hair removal methods, such as plucking, waxing or electrolysis, for 4 weeks prior to laser hair removal
    • Avoid blood thinners, such as aspirin or anti-inflammatory drugs
    • Trim and shave the hair in the treatment area the day before laser treatment

Laser Hair Removal Aftercare

You may notice some sensitivity after laser hair removal. Do not shower or bathe immediately after laser hair removal. Your dermatologist will tell you how long you should wait, but it is usually 8 to 48 hours, depending on the sensitivity of your skin.

Stay out of the sun and do not use a tanning bed for six weeks after treatment or between treatments. Apply a broad-spectrum SPF30 sunscreen every day.
