Laser hair removal operates on the principle of selective photothermolysis, a mechanism directed at melanin-rich structures within the hair follicles. Through the emission of a focused light beam, the laser is absorbed by the melanin present in the hair shaft and follicle, facilitating the transformation of light energy into thermal energy. This process results in follicular damage, thereby impeding subsequent hair growth. Which type of hair responds best to laser hair removal? It is important to note that laser hair removal is most effective on individuals with darker hair and lighter skin, as the contrast between hair and skin tones enhances the absorption of laser energy. Because the laser targets pigment and melanin, and the darker the hair, the richer it is in melanin, and therefore, more responsive to laser treatments. Modern laser technologies, such as diode, Nd: YAG, and alexandrite lasers, offer increased precision and safety during the procedure. Is there any pre-treatment protocol? Prior to the actual treatment, the targeted area is cleaned, and some patients may be given a topical anesthetic gel. This is useful when treating small and delicate parts of the body. The gel usually requires 30-60 minutes to work. What happens during laser hair removal? Laser hair removal takes place in a room specially dedicated to carrying out this procedure, and all the people in the room are required to wear protective eyewear. For both the patient and the doctor, it is essential to protect your eyes from damage. In this procedure, the skin to be treated is stretched, and the high-powered laser is aimed at the skin. The patients are usually able to tolerate the laser pulses, and describe the feeling as warm, a pins and needles type of sensation, or even similar to the feeling of a rubber band being snapped against the skin. The laser operates through the mechanism of destroying the hair through vaporization; this results in small puffs of smoke that resemble the smell of sulfur. This process is designed to target hair follicles while minimizing damage to surrounding skin, enhancing \1. The period of treatment varies depending on the size of the area that needs to be treated. It may take five minutes to treat the upper lip, while the back or the legs may take over an hour. Knowing the approximate \1 for various body parts can assist you in scheduling your appointments effectively. Understanding the treatment duration for different areas can help you plan your sessions more effectively. Is there any downtime? No, there is no real downtime after getting laser hair removal done. You might experience mild erythema (redness) and there might be some degree of localized edema (swelling) but you can resume your daily activities as soon as you get the procedure done. What to do after getting the laser hair removal done? After you have finished your laser hair removal, you must immediately protect your skin from sunlight, as after the procedure, the sensitivity of your skin is enhanced. Therefore, follow these instructions for optimal results: It is essential to keep your skin protected, as \1 can lead to discomfort if exposed to harsh elements. Taking care of your skin post-treatment is crucial for enhancing recovery and maintaining results. Avoid direct sunlight hitting your treated skin, as it might worsen the redness and may cause sunburn.

According to the American Academy of Dermatology, there is a 10-25% reduction in hair after initial treatment. However, I have seen more variation in my clinical practice, as some individuals experience a greater reduction in hair. Another interesting thing that patients experience after getting the procedure done is that their hair gets finer and lighter in color. This can be attributed to the property of lasers to target melanin. How many sessions of laser hair removal are required? It varies from patient to patient. A minimum of 4 sessions are required, each one month apart, to see the desired results. In my clinical practice, I have seen good results within four to six sessions but in certain individuals with underlying medical conditions, such as polycystic ovarian disease (PCOD), more sessions are required. Some patients might need follow-up maintenance sessions for “touch-ups” for optimal results.

As previously mentioned, it may vary if you have any underlying medical conditions. Therefore, seeking professional help from a specialist doctor is mandatory. What are the side effects of laser hair removal? Laser hair removal can have possible side effects. They can be divided into minor and major. Immediate side effects are minor, and they hardly last for a day or two. These include erythema (redness), edema (swelling), and a bit of irritation or discomfort. Other side effects are major, which are rare if you choose the right doctor. Therefore, it is always advisable to get your procedure from a certified dermatologist. Major side effects include blister formation, infection of the skin overlying the treated area, development or reactivation of cold sores, hypo- or hyperpigmentation and even scarring in some cases.
