Laser hair reduction is a dermatology procedure that uses focused light to target hair follicles. The goal is to slow or stop hair growth by affecting the structures involved in regrowth. Teams use medical-grade devices, follow safety protocols, and customize settings based on your skin tone and hair type. Here is what the treatment involves, how long visits usually take, how long the results last, who is a good candidate, and how to find a clinic:
What Is Laser Hair Reduction?
For laser hair reduction, specialists use focused light to heat the pigment in hair shafts, which can disrupt the hair follicle’s growth cycle. The procedure requires a specialized device, trained operators, and protective eyewear. They perform the process according to a treatment plan targeting the specific area being treated. To prepare the skin, specialists typically recommend shaving and generally avoid waxing or plucking, as this allows the follicle to remain intact for effective targeting.
Some laser wavelengths are suitable for individuals with lighter skin and dark hair, while others can accommodate a broader range of skin tones. Your provider will evaluate your hair’s density, thickness, and the timing of its growth phases. Results can vary depending on the treatment area, hair color, and hormonal factors.
Who Is a Good Candidate?
A good candidate for treatment typically has visible hair that contrasts with their skin tone, is in steady health, and has realistic expectations. Modern devices are capable of treating a wide range of skin tones and hair types. You might be asked about:
- Skin tone, tanning habits, and history of hyperpigmentation
- Hair color, thickness, and density in different areas
- Medications that increase photosensitivity
- Hormonal conditions affecting hair growth
- Past scarring or recent procedures
Before treatment, a specialist from a dermatology clinic will take baseline photos, and patch testing can assess your skin’s reactivity. For gray, very light blond, or red hair, the response may be limited because of low pigment. If you have active infections, open wounds, or other factors, they may delay treatment.
How Long Are Treatments?
Session length depends on the size of the area, device speed, and hair density. Shorter treatments may be completed within minutes, while larger jobs may take up to an hour. Preparations involve cleansing, marking, and setting parameters. The device pulses in passes across the grid, and cooling methods reduce surface heat. After treatment, specialists evaluated the skin for redness or swelling. They provide guidance on sun protection, gentle cleansers, and when to resume workouts. Sessions may be spaced out every few weeks.
How Long Does it Last?
Many people notice reduced growth after a series of sessions; a specialist may schedule maintenance as hair cycles shift over months or years. Not all hairs are synchronized, so multiple sessions address different batches of hair. Longevity varies by body site, hair color, and hormones. Some individuals make touch-ups more frequently, while others return sooner. Sun exposure, medication changes, and natural aging each influence outcomes. A dermatologist tracks patterns over time and may adjust settings or intervals to match observed regrowth.
Find a Dermatology Clinic
Your next step is to identify a board-certified dermatology clinic with experience in laser treatments. Start with medical directories, review device types they use, and look for clear pre- and post-care protocols. Bring a list of medications, outline your schedule, and set a photo baseline for comparison. Book a consultation with a qualified dermatology clinic to get a personalized assessment and learn what to expect from a treatment plan suited to your needs.
