A Beginner’s Guide to Laser Hair Removal: How It Works and What to Expect

Laser hair removal has become one of the most in-demand aesthetic treatments worldwide. Whether you’re a clinic owner, technician, or a new client, understanding the basics of this technology can help ensure safer treatments and better results.

How Does Laser Hair Removal Work?

Laser hair removal works by emitting concentrated light that targets the melanin (pigment) in hair follicles. The energy converts to heat, damaging the follicle and slowing down or permanently preventing future growth.

Types of Laser Technologies

There are several types of laser wavelengths commonly used in the industry:

• 755nm (Alexandrite): Ideal for lighter skin tones; fast absorption in melanin.

• 808nm (Diode): Suitable for a wide range of skin types; known for its balance of depth and safety.

• 1064nm (Nd:YAG): Best for darker skin tones; penetrates deeper with less melanin absorption.

Many modern devices combine multiple wavelengths to treat a wider range of clients effectively.

Is It Safe for All Skin Types?

Yes, when the correct wavelength and settings are used. Professionals must assess skin tone, hair type, and treatment area before starting. Devices with integrated cooling systems and intelligent skin detection improve both safety and comfort.

Common Treatment Areas

Laser hair removal is effective on nearly every part of the body, including:

• Face (upper lip, chin, sideburns)

• Underarms

• Arms and legs

• Bikini line and Brazilian

• Back and chest (for men)

How Many Sessions Are Needed?

Most clients require 6 to 8 sessions, spaced 4 to 6 weeks apart, depending on the treatment area, hair density, and growth cycle.

Aftercare Tips for Best Results

• Avoid sun exposure and tanning before and after treatments

• Use SPF daily on exposed treated areas

• Do not wax or pluck between sessions (shaving is allowed)

• Moisturize and soothe the skin with recommended post-treatment products
