Tired of constant shaving, painful waxing, or dealing with ingrown hairs? Laser hair removal offers a long-lasting solution that can dramatically reduce unwanted hair growth. In this comprehensive guide, we’ll cover everything you need to know about this popular med spa treatment.
What is Laser Hair Removal?
Laser hair removal is a medical procedure that uses concentrated light energy to target and destroy hair follicles. The laser’s light is absorbed by the pigment (melanin) in the hair, which damages the follicle enough to significantly reduce future hair growth.
Unlike shaving or waxing, which only remove hair temporarily, laser hair removal targets the root cause of hair growth, providing long-lasting results that many consider permanent.
How Does Laser Hair Removal Work?
The process involves several key steps:
- Light Absorption - The laser emits a specific wavelength of light
- Melanin Targeting - The light is absorbed by melanin in the hair shaft
- Heat Generation - The absorbed light converts to heat energy
- Follicle Damage - Heat damages the hair follicle, inhibiting future growth
Why Multiple Sessions Are Needed
Hair grows in cycles, and the laser is only effective on hairs in the active growth phase (anagen). At any given time, only about 20-30% of your hair is in this phase. This is why multiple treatments spaced 4-6 weeks apart are necessary to target all hair follicles.

Face
- Upper lip

What to Expect: Before, During, and After
Preparing for Treatment
2-4 weeks before:
- Avoid waxing, plucking, or electrolysis (shaving is okay)
- Stay out of the sun and avoid tanning
- Stop using self-tanners
Day of treatment:
- Shave the treatment area 24 hours before
- Come with clean skin, free of lotions or deodorant
- Avoid caffeine if you’re sensitive to discomfort
During Your Session
- You’ll wear protective eyewear
- A cooling gel may be applied to the skin
- The technician will press the laser handpiece against your skin
- You’ll feel a snapping sensation, like a rubber band
- Treatment times vary by area (15 minutes for underarms, 45-60 minutes for legs)
After Treatment
- Mild redness and swelling is normal (like a mild sunburn)
- Apply aloe vera or cooling gel as directed
- Avoid sun exposure and use SPF 30+ sunscreen
- No hot showers, saunas, or exercise for 24-48 hours
- Hair will shed over the next 1-3 weeks
How Many Sessions Do You Need?
Most people require 6-8 sessions for optimal results, though this varies based on:
| Factor | Impact on Sessions |
|---|---|
| Hair Color | Darker hair responds better (fewer sessions) |
| Skin Tone | Contrast between skin and hair affects efficacy |
| Treatment Area | Coarser hair areas may need more sessions |
| Hormones | Hormonal hair growth may require maintenance |
| Hair Density | Thicker hair may need additional treatments |
After completing your initial series, many people enjoy years of smooth skin with only occasional maintenance sessions.
