How to Prepare for Laser Hair Removal treatments: Scientific Considerations and Guidelines


Abstract: Laser hair removal has become a popular and effective method for long-term hair reduction. Proper preparation before laser hair removal is essential to ensure optimal results and minimize potential risks. This article provides a comprehensive overview of scientific considerations and guidelines for individuals preparing for laser hair removal. It covers skin and hair characteristics, pre-treatment assessments, preparation steps, potential side effects, and aftercare measures.


Introduction: Laser hair removal is a cosmetic procedure that utilizes laser technology to target hair follicles, leading to their reduction and, in some cases, permanent removal. Proper preparation is crucial for achieving the best results and preventing complications. This article aims to offer evidence-based guidelines for individuals planning to undergo laser hair removal treatments.


Skin and Hair Characteristics: The success of laser hair removal is influenced by the interaction between the laser’s energy, melanin pigment in your hair shaft, and the target hair follicles. Key considerations include skin type, hair color, and hair thickness. The Fitzpatrick skin type classification and the Lumenis scale can help determine the appropriate laser settings for various skin tones.


Pre-Treatment Assessments: A thorough pre-treatment assessment is vital to ensure the safety and effectiveness of laser hair removal. Individuals with a history of skin conditions, such as herpes simplex, eczema, or active infections, should disclose this information to their practitioner. It might be a good idea to discuss your concerns with your dermatologist before your laser hair removal appointment.


Preparation Steps:

  1. Avoid Sun Exposure: Sun exposure increases the risk of complications, such as hyperpigmentation and burns. Patients should avoid tanning, both natural and artificial, for at least four to six weeks before treatment.
  2. Take a photo of the skin patch WITH your Hair BEFORE you shave. Save this photo somewhere. Check it out, say, a year from the start of your laser hair removal to visualize the progress. Otherwise, you will think you have as much Hair as you have begun with! 
  3. Shave the Treatment Area: It is recommended to shave the area to be treated a day before the appointment. This ensures that the laser targets the hair follicle and not the Hair above the skin’s surface.
  4. Avoid Certain Products: Patients should refrain from using skincare products containing retinoids, alpha hydroxy acids (AHAs), and beta hydroxy acids (BHAs) for a week before treatment, as these can sensitize the skin and increase the risk of adverse effects.
  5. Skip Depilatory Creams and Waxing: Depilatory creams and waxing should be avoided before laser hair removal, as they can disrupt the hair follicle and affect the efficacy of the treatment.

Potential Side Effects: Laser hair removal is generally safe, but potential side effects can occur, especially if proper preparation is not followed. These include:

  • Temporary Discomfort: Patients may experience mild discomfort or stinging sensations during the procedure, which can be managed with cooling methods.
  • Skin Irritation: Temporary redness, swelling, and mild irritation are common immediately after treatment.
  • Hyperpigmentation/Hypopigmentation: Changes in skin pigmentation can occur, particularly in individuals with darker skin tones.
  • Burns: In rare cases, burns can occur. Assuming your provider is using a proper FDA-approved or cleared laser hair removal machine. To reduce the possibility of complications:
  • Do not sunbathe or tan before and after your laser hair removal appointment.
  • Do not apply skin appearance-altering cream lotions, such as self-tanning lotions. 
  • No tattoos on the areas to be lasered.
  • Do not laser if you have any skin condition that is altering your skin appearance, color, or texture.
  • Herpes Reactivation: Individuals with a history of oral or genital herpes may experience reactivation of the virus after treatment. Antiviral medications may be prescribed to prevent this.

Aftercare Measures: After the procedure, proper aftercare can aid in healing and prevent complications:

  • Apply Cold Compresses: Applying cold compresses can reduce redness and swelling.
  • Use Gentle Cleansers: Mild, fragrance-free cleansers should be used to cleanse the treated area.
  • Avoid Sun Exposure: Sun protection is crucial post-treatment to prevent hyperpigmentation. A broad-spectrum sunscreen with a high SPF should be applied and re-applied as needed.

Conclusion: Proper preparation is essential for achieving safe and effective laser hair removal outcomes. Understanding the scientific considerations related to skin and hair characteristics, conducting pre-treatment assessments, following preparation steps, being aware of potential side effects, and practicing appropriate aftercare measures contribute to successful laser hair removal experiences. By adhering to evidence-based guidelines, individuals can optimize their results while minimizing potential risks associated with the procedure.
