The process of hair removal via laser technique has become very common. It involves destruction of hair follicles that cause hair growth. Various experiments were performed in the past for ensuring authenticity of this technology. After publication of articles by Massachusetts General Hospital, its practice became mainstream with the speed of fire. These days, laser technology is practiced in every continent and is widely accepted by top dermatologists and skin specialists. Increased market demand has led to decrease in laser treatment price. Lately, various handy hair removal laser machines have been made available, leading to self-treatment in homes possible. Laser technology is readily reviewed and various removal methods are suggested in dermatology literature all the time.
Laser hair removal process incorporates selective photothermolysis technology. According to this technology, light wavelength is thrown on selected skin patch which targets specific skin tissues present in skin’s dermal layer.
Many people are insecure of spending a large amount and time on laser technology because they are not sure about its results. In skin medical community, effectiveness of laser technology is no doubt a debatable topic. Various articles are published on laser technology’s effectiveness, whether it is able to deliver permanent hair removal or not, and what are the side effects. In contrast to electrolysis, laser only ensures hair reduction for a long time. It is always a better and hassle free option than waxing or threading.
Another important question readily asked by consumers is that how long does a laser hair removal last?
How long the result of hair removal lasts depends on the type of skin tissues, skin tone, melanin percentage, hair density, hair growth and laser beam concentration. Laser beam usually targets melanin, a chromophore present in hair follicle, that gives pigment to your hair. People with high concentration of melanin have dark skins and black hair. On the contrary, people with light skins and brown/golden hair have low melanin content. Only black or brown hair can be removed because only they are able to absorb photons of laser light. Laser is successfully operated mostly on people with darker tones. Hair removal period lasts longer in people with African/Indian skin color tone.
Multiple sessions are required to impair hair growth pattern because laser technology kills only one phase of hair growth in single session. Naturally, our hair grows in three major phases: anagen, telogen and catagen. First session of laser beam only affects early anagen phase. Generally, people require a complete course of six to eight months involving seven to eight treatment sessions. These generalized parameters largely depend on quality of device as well. People with light hair and loose skins have to take more sessions than those with coarse hair on dark tight skin. It usually takes a period of two to three weeks for treated hair to be shed. Once they are totally shed, the regrowth process results in fully grown hair within four to five weeks.
Before going for laser treatment, one must make sure to avoid laser catching pigments, like excessive sun exposure or skin tanning. Moreover, people using Vitamin C serums and retinol creams should stop this practice if they are planning to have laser treatment.
