The Ultimate Guide to Laser Hair Removal: What You Need to Know.

Laser hair removal has become a popular cosmetic procedure for those seeking a long-term solution to unwanted hair. This guide covers everything you need to know about laser hair removal, including how it works, benefits, preparation, what to expect during and after treatment, and tips for choosing the right provider.

Understanding Laser Hair Removal

Laser hair removal uses concentrated light energy to target and destroy hair follicles, which inhibits future hair growth. The laser selectively targets melanin (the pigment that gives hair its color), making it most effective on individuals with dark hair and light skin. However, advances in technology have made laser hair removal an option for people with a wider range of skin tones and hair colors.

Benefits of Laser Hair Removal

  • Long-Term Results: While it may require multiple sessions, laser hair removal can significantly reduce hair growth, with many experiencing permanent hair loss after an average of three to seven sessions.
  • Precision: Lasers can selectively target dark, coarse hairs while leaving the surrounding skin undamaged.
  • Speed: Each laser pulse takes a fraction of a second and can treat many hairs at the same time. Small areas such as the upper lip can be treated in less than a minute, and larger areas, such as the back or legs, may take up to an hour.
  • Predictability: Most patients see permanent hair loss after three to seven sessions.

Preparing for Laser Hair Removal

Preparation is key to a successful laser hair removal experience. Here’s what you need to do before your treatment:

  • Consult a Professional: A consultation with a dermatologist or a licensed laser technician is crucial to assess your suitability for the procedure and discuss any concerns.
  • Avoid Sun Exposure: Protect your skin from the sun for six weeks before and after treatment, as sun exposure can affect the effectiveness of the procedure and increase the risk of complications.
  • Refrain from Other Hair Removal Methods: Avoid plucking, waxing, and electrolysis for six weeks before treatment, as these methods can disturb the hair follicle and reduce the effectiveness of laser hair removal.
  • Shave the Treatment Area: Shaving the area before your session can improve the results and decrease the risk of burns.

During the Procedure

During laser hair removal, you and your technician will wear protective eyewear to shield your eyes from the laser. The technician will then adjust the laser equipment according to the color, thickness, and location of your hair being treated as well as your skin color.

The area will be cleaned, and a topical numbing gel might be applied to your skin to reduce discomfort during the treatment. The laser treatment itself involves a hand-held laser instrument being pressed to your skin. After the laser is activated, the beam passes through your skin to the hair follicles. You may feel discomfort, such as a warm pinprick, and you’ll likely feel a sensation of cold from the cooling device or gel.

Aftercare and Recovery

After the procedure, you may notice redness and swelling for the first few hours. Applying ice to the treated area can help reduce discomfort. Your technician may also apply a steroid cream to the treated area if you have a skin reaction immediately after hair removal.

Avoid sun exposure and use a broad-spectrum SPF sunscreen to protect your treated skin from UV rays. Over the next month, the treated hair will fall out. Use gentle skin care products and avoid waxing or plucking hairs in the treated area.

Choosing the Right Provider

Selecting the right provider is crucial for a safe and effective laser hair removal experience. Look for a licensed professional with experience in laser hair removal on your specific skin type and hair color. Ask for referrals, read reviews, and consider a consultation to discuss their experience, the type of lasers they use, and their approach to treatment.


Laser hair removal offers a promising solution for those looking to reduce unwanted hair. By understanding the procedure, preparing properly, and choosing the right provider, you can achieve smooth, hair-free skin with minimal discomfort and long-lasting results. Remember, patience and adherence to your provider’s advice are key to the success of your laser hair removal journey.
