If you’ve been thinking about ditching the razor or canceling your next waxing appointment, you’re not alone. Laser hair removal has gained immense popularity for long-term hair reduction. Here’s everything you need to know before starting treatments.
What “Permanent Reduction” Actually Means
Laser hair removal produces permanent hair reduction — not permanent hair removal. This is an important distinction. The FDA specifically approves laser devices for “permanent hair reduction,” which means a significant, lasting decrease in the number of hairs that regrow after completing a full treatment series.
That’s not zero hairs forever. But it’s also not temporary. It’s 80-95% of the hair gone — permanently.
Laser Reduction vs Removal
Laser permanently destroys the follicles it successfully targets during treatment. Those follicles don’t grow hair again. But, because of your hair growth cycle, not every follicle gets targeted in every session and hormonal changes can activate previously dormant follicles years later. That’s why the FDA says “reduction” instead of “removal.”
How to Prime Your Skin Ahead of Laser Hair Removal
While the process itself is relatively quick and easy, properly caring for your skin beforehand is crucial for achieving the best results. Follow these tips to ensure you show up ready for smooth, stubble-free skin.
1. Exfoliate Before Your Appointment
Gently sloughing off dead skin cells primes your body for laser hair removal success. The beams target the pigment in your hair follicles, so removing any barriers on the skin’s surface helps the laser penetrate properly. Use a loofah mitt or body scrub 2 to 3 times a week leading up to your session to reveal fresh, glowy skin. Just don’t overdo it––stick to gentle exfoliants to avoid irritation.
2. Stop Removing Hair 2 to 4 Weeks Before
Laser hair removal devices disable the hair follicle to prevent future growth. So, if you shave, wax, or tweeze in the short weeks before your appointment, there won’t be enough visible hair for the laser to zap. Let your stubble grow out slightly so there’s an optimal amount of coarse hair for the device to target. Resist the urge to trim or nip hair between sessions, either.
3. Avoid Sun Exposure
A base tan and fresh sunburn are two pre-laser no-nos. Like exfoliating, lasers work best on skin sans excess pigment. Bronzed skin can potentially inhibit the beams from reaching all the undesirable dark hair you want gone. Additionally, sensitive, freshly UV-exposed skin risks adverse reactions. Wear sunscreen religiously for a few weeks beforehand. For beach, pool, or any outdoor days, cover areas to be treated or consider postponing your visit.
4. Stop Retinoids Beforehand
Prescription retinoids and over-the-counter retinol creams spur fast skin cell turnover. The resulting fresh layer is more prone to laser sensitivity, which you may want to avoid. Talk to your practioner for the best skincare recommendations, but consider pausing any strong products at least two weeks prior to your appointment.

Frequently Asked Questions
Does laser hair removal really work?
Yes, laser hair removal works. It is an effective, long-lasting way to significantly reduce unwanted hair and prevent ingrown hairs. While it is technically a “permanent hair reduction” rather than a 100% permanent removal, most people experience a 60% to 90% reduction in hair growth after 6 to 8 sessions.
Is laser hair removal permanent?
Laser hair removal produces permanent hair reduction — the FDA’s words. Clinical data shows 80-95% of treated hair is permanently gone after a full series of 6-8 sessions. Whatever regrows is typically finer, lighter, and sparser. It’s not 100% elimination of every hair forever, but it’s the closest thing to permanent available in aesthetic medicine.
Is laser hair removal safe for all skin tones?
Yes, laser hair removal is safe for all skin tones, but it requires the right technology. The laser must be able to target the pigment in the hair follicle without damaging the pigment in the surrounding skin.
How many sessions are needed?
Laser hair removal requires a series of 6 to 8 sessions, typically spaced 4 to 6 weeks apart, to achieve optimal results. Depending on your hair type, skin tone, and the area being treated, it can take several months to complete the process.
When should I start laser hair removal?
To get the best results by summer, the most strategic time to begin laser hair removal is actually in the fall or winter. This “off-season” gives your body the time it needs to go through multiple sessions so that by spring or summer, you’re already seeing significant reduction in hair growth and may even be close to finished.
