Laser hair removal is one of the most common cosmetic treatments performed today, with many people wanting to remove excess hair in this manner rather than the more time consuming traditional methods. Waxing, shaving and plucking only produce short term results and can be fraught with unwanted side effects.
Laser hair removal has been shown to be fast, gentle and effective and is becoming more popular as people recognise the benefits it can offer. This procedure can be a solution for sufferers of ingrown hairs and shaving rash as the hair is removed and the associated maintenance with having to wax or shave is no longer needed to keep the area free from hair. Laser can be utilised safely on many areas of the face and body, and after several treatments a significant reduction in the number of hairs will be evident.
Laser is a single wavelength of light which is pulsed onto the skin in the treatment area to in order to reduce the number of actively growing hairs. The light energy converts to heat once absorbed into the hair shaft thus damaging the follicle and preventing it from growing another hair. The process is called selective photothermolysis in which the laser targets the melanin rich hair follicle whilst bypassing the lighter colour of the skin.
This heating of the hair follicle is what is felt during treatment resulting in a slight pinching sensation. It is important that laser hair removal treatments are accompanied by a cooling mechanism to reduce discomfort from the treatment and protect the skin whilst ensuring the treatment is delivered effectively. The length must be removed off the hair prior to treatment (usually by shaving) to ensure the energy is transferred to the base of the follicle where the cells responsible for hair growth lie. This process damages the cells responsible for growing a hair if it is in the active or anagen stage of growth.
Several treatments are required as not all hairs are in the active stage of growth at one time, though a reduction in the number of hairs should be noticed after each treatment. Subsequent treatments are usually performed when the next phase of hairs appear in around 4 - 5 weeks time. Hair that regrows will be fine and sparse and these are the hairs that will be targeted in the next treatment. During a course of laser hair removal treatments it is important that the skin remain as pale as possible as this results in a more effective treatment as well as minimising unwanted side effects. Tanning and solariums should be avoided and fake or chemical tans should not be used at least 1 week prior to treatment.
Post treatment it is advisable to keep the area cool for the next several hours, so avoid sun exposure as well as hot baths/sauna/spa’s. The hair remains in the follicle post treatment and gradually moves up and sheds within approx 2 weeks.
No waxing or plucking should be done in between treatments; however the area can be shaved if needed. Removing the hair with waxing or plucking during the course of laser hair removal treatments will render the treatments less effective as there will be less hair present to treat. Costs vary depending on the area and the amount of hair growth of the individual, as will the number of treatments required.
