Laser hair removal was approved by the FDA in the 1990s and is considered a safe and effective way to permanently remove and reduce hair. With the right laser, appropriate settings and accurately spaced time between treatments, laser hair removal is incredibly effective and results in 90 percent permanent hair reduction. Many patients ask why this is not 100 percent. The fact is that as our bodies age, we go through hormonal changes. These hormonal changes can trigger new hair growth. It is not uncommon to need a "touch up" at some point in your life after having laser hair removal. Laser hair removal works by using pulsed laser light. The laser light is attracted to the pigment in the hair and travels down the shaft creating a "thermal injury" to the follicle. This trauma to the follicle is what prevents future growth. It's important to note that lasers cannot effectively treat grey, red, blonde or fine hair. Hair grows in three phases, which is why it's so important to maintain a set schedule for effective treatment. The only hair that will receive effective treatment are the ones currently growing. Therefore, as our bodies go through these three stages of hair growth, we must time treatment appropriately to catch all the new hair entering this growth phase. Body hair should be treated every six weeks while facial hair should be treated every four weeks. A minimum of 10-12 treatments is recommended to reach 90 percent permanent hair reduction.
