Laser Hair Reduction: What to Expect Before, During & After

Considering laser hair reduction but nervous about the process? Here's everything you need to know before, during, and after your treatments. Laser hair reduction uses concentrated light energy to target melanin in hair follicles. The heat destroys the follicle's ability to produce hair. It's permanent hair reduction (not removal, as some regrowth may occur) and works best on darker hair. Before your appointment, avoid sun exposure and certain medications that increase photosensitivity. Shave the area (don't wax or pluck — the follicle needs to be intact). Arrive with clean, makeup-free skin. Some clinics apply a cooling gel for comfort. During the treatment, you'll feel a warm sensation or mild snapping feeling as the laser fires. Most people find it tolerable. Sessions typically last 15-60 minutes depending on the area being treated. You can return to normal activities immediately, though the area may be slightly red. After treatment, the hair doesn't fall out immediately. Over the next 1-3 weeks, treated hairs will shed. You'll notice reduction in hair density with each session. Most people need 6-10 sessions spaced 4-8 weeks apart for optimal results. Results vary based on skin tone, hair color, and hair thickness. Darker hair responds better than blonde or red hair. Lighter skin shows better results, though modern lasers like Nd:YAG can treat darker skin tones safely.
