How does Laser Hair Removal work?

The primary principle behind laser hair removal is selective photothermolysis. This process involves targeting the melanin pigment in the hair follicles while minimizing damage to the surrounding skin. Melanin absorbs the laser energy which is then converted into heat, damaging the hair follicles and inhibiting further growth. Different laser systems such as alexandrite, diode and Nd:YAG are used based on the patient’s skin type, hair colour and the location being treated.

One of the major advantages of laser hair removal is its long-term effectiveness. Unlike temporary methods like shaving or waxing laser treatment can provide long-lasting results. Multiple treatment sessions are typically required to target hair follicles in different growth phases. Since hair growth occurs in cycles only follicles in the active growth phase can be effectively treated. Thus, several sessions spaced over several weeks or months are necessary to ensure that all targeted follicles are treated during their active growth stage.

Furthermore, laser hair removal offers precision and efficiency. The treatment can selectively target dark coarse hairs while leaving the surrounding skin undamaged. The laser’s wide beam allows for the rapid treatment of multiple hair follicles simultaneously making it suitable for large areas like the back or legs. Moreover, the procedure is relatively quick with each laser pulse treating an area approximately between 2cm and 8cm. Small areas such as the upper lip can be treated in a matter of minutes while larger areas may take up to an hour.

Laser hair removal is also known for its versatility as it can be applied to various body areas including the face, legs, arms, underarms, bikini line and even sensitive areas like the nipples or the pubic region. It is important to note however that laser hair removal may not be suitable for all skin and hair types. The procedure is generally most effective on individuals with light skin and dark hair as the laser targets the melanin pigment. People with lighter hair colours such as blonde, red, or grey may experience limited results due to the lack of melanin to absorb the laser energy.

While laser hair removal offers numerous benefits it is essential to acknowledge its limitations. Complete and permanent hair removal is not always achievable for everyone as individual responses to treatment can vary. Some individuals may experience significant hair reduction while others may only achieve hair thinning. Factors such as hormonal imbalances, underlying medical conditions and genetic predisposition can influence the outcome. Additionally, new hair follicles can develop due to factors like aging or hormonal changes requiring maintenance sessions to sustain the desired results.
