How Laser Hair Removal Works and What You Need to Know Beforehand

Unwanted hair can be a source of frustration for many people. Shaving, waxing, and other hair removal methods often require frequent maintenance. Laser hair removal is a popular option for those seeking longer-lasting solutions. Before you schedule a treatment, understand the process, preparation steps, and potential risks involved.
What Is Laser Hair Removal?
Laser hair removal is a cosmetic procedure that uses concentrated beams of light to target hair follicles. The laser emits light that is absorbed by pigment in the hair, effectively damaging the follicle to inhibit future hair growth. While it is not a permanent solution, it can provide long-term hair reduction with regular treatments.
This procedure is commonly performed on areas such as the legs, underarms, bikini line, face, and back. Most people require multiple sessions to achieve desired results, as hair grows in cycles. Over time, treated areas typically have thinner, finer hair or no hair growth at all.
How Does It Work?
The hair removal procedure works by selectively targeting and heating hair follicles without damaging the surrounding skin. Lasers deliver a specific wavelength of light, which is absorbed by the melanin (pigment) in the hair. This heat damages the follicle, disrupting its ability to regrow hair.
Because the laser targets pigment, the treatment is generally more effective for people with darker hair and lighter skin tones. Technological advances have made the procedure more inclusive, and some lasers are designed to work on a wider range of skin tones and hair colors.
Multiple treatments are necessary because hair grows in three stages. Lasers are most effective during the phase when the hair is actively growing. Since not all hairs are in this phase at the same time, treatments are typically spaced several weeks apart to target as many active follicles as possible.
How Do I Prepare for the Treatment?
Preparation is a necessary part of achieving optimal results with laser hair removal. You will likely be asked to shave the treatment area one to two days before your appointment. Short hair helps the laser energy focus on the hair follicle, rather than burning hair on the surface of the skin.
Avoid sun exposure prior to treatment, as sunburn or tanning can increase the risk of side effects and reduce the laser’s effectiveness. Self-tanning products should also be avoided for similar reasons. Skipping waxing, plucking, or epilating is necessary in the weeks leading up to your session. These methods can remove the hair follicle, making the laser less effective.
Are There Risks?
Laser hair removal is generally safe, but like any cosmetic procedure, it comes with some risks. Mild redness, swelling, or skin irritation are among the most common side effects and typically resolve within a few days. Some individuals may experience temporary pigment changes, such as lightening or darkening of the treated area. Individuals with darker skin tones or certain medical conditions may be at a slightly higher risk of side effects. A consultation with a specialist can determine whether hair removal is a good option for your skin and hair type.
Hair removal with lasers can cause blistering, scarring, or other complications, though this is rare. If it is performed by an inexperienced provider or if improper settings are used, the chance of adverse effects is higher. Choose a licensed and qualified practitioner who uses FDA-approved equipment.
