Laser hair removal has grown in popularity in recent years due to its claim that it can effectively stop hair growth for a prolonged period of time. But, how does laser hair removal work? And, what type is best for you? This article provides you with a brief background of how laser hair removal works, discusses the various types of laser hair removal, and offers considerations to keep in mind when choosing laser hair removal.
What Is Laser Hair Removal?
Before we begin to discuss different types of laser hair removal methods, it is important to understand exactly what laser hair removal is. Laser hair removal is a process by which pulses of energy-filled lasers are used to target hair follicles and remove the unwanted hair. The lasers are specially designed and programmed to match the size and depth of the particular hair follicle that they are targeting, and to prevent damage to any of the skin surrounding the hair follicle.
Laser hair removal tools are most often used by a licensed physician or technologist who has training in the area of laser hair removal. While laser hair removal can be used on a variety of different body parts, it is most commonly used on the back, thighs, bikini line and various parts of the face.
Types of Laser Hair Removal
While there are a variety of different brands of laser hair removal machines, they can be broken down into three basic categories. The first type of laser hair removal is called the Thermal Laser Mechanism. This technique actually uses local heating, which is transferred immediately from the laser beam to the hair follicle, where it is immediately destroyed.
A second type of popular laser hair removal is called is the mechanical method. The mechanical method involves a process by which shock waves are actually expelled from the laser, and destroy the hair and hair follicle. Finally, photochemical laser hair removal, which is one of the newest types of laser hair removal, involves shooting free radicals at hair and hair follicles in order to impede their growth.
Things to Keep in Mind
If you are thinking about having laser hair removal, there are a number of considerations to keep in mind before scheduling an appointment. First, it is important to understand that while laser hair removal is not completely permanent, it will prevent hair from growing for three to five years. If you are concerned about the commitment that this entails, you may want to use another method of temporary hair removal, such as waxing or shaving.
Secondly, you must realize that laser hair removal is a relatively new technology, and because of this, there are several kinks that need to still be worked out. For example, while laser hair removal works well on blond hair, it is not always as effective on red, brown or black hair. Consult with a licensed dermatologist before starting any type of laser hair removal.
