Laser hair removal is one of the most effective hair removal techniques if one is looking at a long term solution. It has been gaining acceptance steadily as technology has also improved over the last few decades. It is one of the few good options of removing hair almost permanently. It might appear to be expensive when you compare it to more conventional methods like shaving or waxing. However, if you add up the cost those methods are going to incur in the long run you would realize that laser is the cheaper option. A session of laser hair removal in London would not cost you much higher eventually it depends on the area one intends to cover. 

How does it work?

Laser hair removal works by focussing light on hair follicles. The melanin in the hair causes the hair to absorb heat. This destroys the hair all the way to the root. This causes a little pain like tiny pinpricks. The hair normally does not grow back. When it does grow back it is much thinner and hard to notice. The session has to be done a few times to remove hair completely. This is because the hair follicles at any one time would be at different stages of their growth. It is considered a safe process. It does require a trained professional to administer the treatment though

Precautions to take

There are malicious rumours about laser causing cancer. These are not based on truth. The risks of using laser hair removal are real if it is not done by a professionally qualified practitioner.  There is the possibility of slight inconveniences that happen rarely. These issues like redness of the skin, discolouration of skin, crusting, blistering etc. are temporary issues that disappear within a few hours or days. 

You should meet with a doctor and have a discussion before deciding to go through with the process. There are precautions that you can take which will leave nothing to chance. You should discuss any history of skin conditions. If you have any past experience of using a procedure for hair removal in the past, that should be discussed too. The doctor would advise you to stay out of the sun.  You should also discuss the medications you’re under and if they could have any adverse effects during the procedure. Shaving the area the day before is encouraged. If the hair to be removed is too long or thick it could harm your skin. Other methods like waxing, threading or plucking are discouraged before the process. This is because unlike shaving, the other methods get rid of the hair follicles along with the root. Shaving leaves stubble behind, which can be targeted by the laser.

During the procedure, you would be provided with safety goggles. Even after the process, you will be required to avoid the sun for a few days. The skin would be a bit sensitive immediately after the procedure, hence the doctor would give you some skin care advice as well.
