Shaving before a laser hair removal session is standard practice on a path to hair-free skin, and there's a clear reason for it. The laser works by targeting hair pigment in the follicles beneath the skin, not the hair above it. Shaving removes surface hair while leaving the follicle completely intact and ready to be targeted.

Keeping the hair short at the surface also reduces the chance of any skin irritation during treatment. The laser energy is directed where it needs to go, down into the hair follicle, rather than interacting with longer hair above the skin.

Why You Should Not Wax Or Pluck

While shaving is encouraged, waxing and plucking are a different story. Both methods remove the hair directly from the follicle, which is exactly what the laser light needs to do its job. No follicle means no target, and no target means the treatment can't work as intended.

Waxing or plucking between sessions doesn't just affect a single appointment. It can reduce overall effectiveness and push your results further down the road. Shaving is the only hair removal method, unlike waxing, plucking or depilatory creams, that keeps the follicle where it needs to be.

When To Shave Before Your Appointment

Timing matters when it comes to shaving before a session. Shaving within 24 hours of your appointment is generally the standard. It’s close enough to the treatment that surface hair is minimal, but with enough time for any minor skin reaction to settle.

That said, if your skin tends to experience side effects like irritation after shaving, giving yourself a little more time is a reasonable adjustment. As with most things in laser hair removal, your provider's specific instructions, including laser settings tailored to your skin tone and hair type, take priority. Follow their guidance for the best results.

Shaving Between Sessions

Between appointments, shaving is generally fine if you need to manage hair in the treated area. It's the one method that won't interfere with your treatment plan, and as a bonus, it helps avoid the ingrown hairs that waxing and plucking can leave behind.

Waxing, tweezing, tanning beds, and self-tanning products should all be avoided throughout your entire series, not just before individual appointments. And one thing worth knowing: laser hair removal relies on pigment in the hair follicle to work, and hair colors like white or gray hair typically don't respond to treatment.
