Laser Hair Removal
There are the most of body parts which are covered up with the hairs. These parts are mostly upper lip, chin, cheeks, back, legs, fingers, feet or toes and having these is none of us desire. It is common to have these hairs, however certain other factors like genetics, medications, hormones, or some abnormalities can also lead to these problem.

The majority of us try to get rid of this problem either by plucking hair or by waxing. Both these methods are highly painful ones. The cosmetic world claims a number of hair removing strategies but none of them is permanent. Apart from waxing, shaving and even hair removal creams, laser hair removal is one of the best methods for hair reduction.

It works perfectly to reduce stubble where waxing usually doesn't. It mainly uses a high intensity light beam which destroys the hair at its roots. Different people experience different success level in this, but it is generally a permanent solution to unwanted hairs.

It took 20 years for Laser hair removal to become commercially available in the mid-1990s. The efficacy of laser hair removal is now generally accepted in the dermatology community and laser hair removal is widely practiced in clinics, and even in homes using devices designed and priced for consumer self-treatment.

Types of Laser Hair Removal
Types of Laser
There are currently 4 types of lasers for hair removal. Each of these lasers has been FDA-approved for laser hair removal. They are proven effective, fast and safe methods for successful hair removal and permanent hair reduction. As compared to shaving or waxing, all the given below four types of lasers for hair removal provide longer lasting results with less frequent maintenance.

Diode Laser Hair Removal

The diode laser is the most effective and is endorsed by the Harvard and Massachusetts universities. With this type of laser, the destruction of the hair bulb takes place by transmission of heat to the pigment, which contains the follicle, without damaging the skin. No gel or anesthesia is usually required in this type as a part of this laser applied to the skin produces a cooling effect which prevents pain and possible burns.

This method is 40% more effective than other hair removal systems, but at the same time it is also more expensive than other treatments.


The Alexandrite laser has a shorter wavelength system compared to other types of lasers and works quickly. It is best for light skinned individuals because it can lighten the pigment of dark skin. It has been proved to be good for waxing legs and underarms of women. It is widely used in clinics across the globe.


The Ruby laser is the oldest type of laser used in hair removal. It is best for people with light or fine hair and fair skin. Compared to newer lasers, the Ruby covers a smaller area and can be more time-consuming.

ND and LP ND Yag

This Laser has the longest wavelength and is therefore capable of treating all skin pigments. However, it may not be as effective for long term hair removal. Patients also report this laser as causing more discomfort. This laser can be used to treat a large area quickly.

Number of Sessions

This is the most frequently asked question, that how long does it take to achieve the desired result by Laser Hair Removal. According to the studies, average number of sessions to achieve 80 percent hair reduction is between four to six sessions, as long as the candidate has fine skin color and dark hair. And if a precautionary approach is followed, then the whole process may end up taking eight sessions. Normally there are intervals of breaks between sessions, which can mean it may be a lengthy process. But the result is expected to last longer than waxing or shaving.

Getting prepared for hair removal

Before the start, you are advised to stay away from the sun at least few days to avoid getting sunburned. Skin which has been exposed to the sunlight or burn is difficult to treat, and it creates discomfort during the process. Other than this, any waxing or shaving sessions must be stopped prior to each laser removal session. Lotion, perfumes and any other cosmetic should be cleared from the surface of the skin to prevent an allergic reaction.

During the treatment

To lessen the pain, a topical anesthetic is usually applied on parts of the body that are having treatment.
