Your guide to laser hair removal

Does Laser Hair Removal Hurt?

By: Charlotte's Book

If you've been considering the zap, you probably know it's a winter-time endeavor, and if you've been looking at the calendar (or out the window) you know there's just a few months left to schedule the series of laser treatments required to clean things up for summer beach scenes.

In the spring spirit, we pulled together a quick guide to laser hair removal: the why, where, who and how, plus Charlotte's Tips. If you're curious about something we didn't cover, leave a comment!

Laser hair removal is a relatively fast and effective treatment for getting rid of unwanted hair on any part of the body. A focused traditional laser or intense pulsating beam of light (IPL) is sent through each hair shaft into the follicle to destroy the root; this weakens the follicle, which causes the hair to eventually fall out and disable future growth. The treatment requires an initial series of sessions followed by periodic maintenance treatments.

Lots of in-office devices are available, including Diode, Alexandrite, LightSheer, and Nd:YAG, Gemini, elos Plus, and more. A laser hair removal specialist can determine what's best for you, considering hair color, texture, location, size of the treatment area. Often, a combination of devices will be used to achieve the best results.

People with light skin and dark hair have had the most success with laser hair removal, but advances in technology make it possible for darker skin tones to achieve successful results with the right laser (Diode or Nd:YAG). Generally, people with super-light hair don't see results.

A note of caution: darker skin tones risk hyperpigmentation and scarring, so you should seek treatment from a specialist who knows the safest and most effective technique for your skin color.

You know the deal: everything depends on a person's threshold for pain. Some people say it's painless, others find it completely intolerable. In most cases, a topical anesthetic is applied to the surface area or a cooling device is used for skin protection and additional comfort; however, pain management is subjective to the provider, so best to inquire beforehand if you have a low tolerance for pain.

The laser device is moved across the targeted area, sending laser energy deep into each hair shaft to destroy hair by its root. This causes a snapping or burning sensation that can be compared to the snapping of a rubber band, quick match burn, or even a bee sting.

When treatment is finished, ice-packs, anti-inflammatory cream, or a cold compress may be applied to alleviate any discomfort, and sunscreen should be applied to areas of sun exposure—but by no means should you be spending time in the sun post-laser!

Because hair grows in cycles and the lasers can only destroy follicles in an active growth cycle, multiple sessions are necessary to achieve ideal results.

How many sessions needed depends on a person's particular hair growth pattern; the course of treatment to target all hair follicles ranges from 3 to 10 sessions spaced 4 to 8 weeks apart. Each session takes ten minutes to an hour, depending on the treatment area. The entire series often takes at least a year to complete and is best maintained by an annual touch-up treatment.

Right after, the treated area often feels warm and may show redness and mild swelling that completely resolves within two days. You may return to your daily routine immediately after following treatment, being sure to avoid activities that cause sweating for 24 hours.

People with darker complexions may experience temporary blisters, and in rare cases, scarring or pigment discoloration may occur. If these symptoms occur, medical attention is necessary.

Results change based on age, ethnicity, hormone levels, and the color and texture of hair being treated. But while the degree of results varies, hair immediately appears scarcer and continues to shed within 1 to 3 weeks post treatment.

Either can administer the treatment, but of course—the dermatologist should be board-certified (see our recommended listings) and the aesthetician should be fully licensed (list here). Make sure whoever you see specializes in this treatment.

Expect to spend $200 – $1200 per session, depending on surface area being treated.
