How Lasers Work in Laser Hair Removal

Leave a comment

Laser hair removal works by the process of selective targeting of a specific area of the body and using a specific wavelength to absorb light into that area. It does not work on a hair by hair basis, instead it focuses a wide beam of light that treats many hairs at one time. The wavelength of light absorbed has to be sufficient enough to damage the targeted tissue area while leaving the surrounding area basically untouched. The principle behind this process is called selective photothermolysis.

Lasers are intense beams of monochromatic and coherent light. These light beams are produced by laser devices that contain either minerals or gases. The four main types of lasers are solid state, semiconductor, gas and dye.

An electric current stimulates the gas or mineral properties which excites the atoms. The atoms then emit narrow, cohesive, parallel light beams which are all the same wavelength. The light beams are focused just for a fraction of a second on the dark hair pigment at the matrix of the dermal papilla, which is the small, cone shaped indentation at the base of the hair follicle that the hair bulb fits into. The light beam is absorbed and heats the pigment which vaporizes the dermal papilla. The more intense the light beam the hotter it makes the pigment. This results in the dermal papilla being severely damaged or destroyed.

Most people believe that laser hair removal works best on hair that is in its anagen phase. This means that the hair is actively growing and is attached to the dermal papilla. The theory behind this belief is that if the dark pigment in the hair shaft extends all the way down to the dermal papilla, it will be destroyed and vaporized by the coherent light beam that is focused upon the area. This happens because the light beam will follow the dark pigment all the way down to the derma papilla.

Visible light has wavelengths that range from 390 to 770 nm, or nanometers. Lasers operating in this range allows for successful laser hair removal without causing any damage to the dermal tissue. Lasers with a light source that operates between 700 to 1000 nm targets melanin in the hair shaft effectively. For example, the wavelength of an alexandrite laser is 755 nm, which is red in the visible range of the electromagnetic spectrum, making its target melanin. The stronger, or greater, the wavelength, the deeper it penetrates target selectively absorbing the wavelength.

Laser hair removal uses several varying wavelengths of laser energy. These wavelengths range from near infrared radiation to visible light. The three most commonly used lasers for hair removal are Alexandrite, Pulsed diode array, and NeoDymium Yttrium Aluminum Garnets, Also know as Nd:YAGs. The wavelengths of these lasers are 755nm, 810nm, and 1064nm respectively.

Laser hair removal utilizes a complex system of science and physics which are precisely balanced to work effectively and safely on the human body. As technology continues to advance in laser hair removal, this process continues to grow in popularity.

Finding Out Early On About Alzheimers

Leave a comment

Alzheimers is an extremely debilitating disease. Presently, there are no known cure or treatment for this irreversible threat to a mature person’s mental and personal health. Once a person has been diagnosed with Alzheimers, the duration and course of the disease will vary from five up to twenty years.

While the prospect of Alzheimers disease is truly grim, there continues to be steady breakthroughs from experts that help hope persist that eventually, prevention and cure for Alzheimers may be found. Before that though, there are lot of questions to be answered and the race to find the cure continues.

Despite this, it is important to take note of the early signs of Alzheimers, for friends loved ones and yourself. Taking note of the early signs of Alzheimers will help everyone involved prepare and understand all that is entailed in arranging for care and what to expect as the illness progresses.

Below are some early signs of Alzheimers to look out for.

Downscale

While memory loss is commonly mentioned as the one of the early signs of Alzheimers, it has been noted that unexplained and sudden weight loss usually occurs within individuals who suffer from Alzheimers. They have found that the weight loss happens way before any actually memory loss begins.

If you or someone you care about begins to lose weight unexpectedly, consult your doctor for probable cause and if there are no reasons found then you should have tests for Alzheimers done.

Forgetfulness

The most common early sign of Alzheimers is the loss of short term memory. More often than not, at the very early stages, this short term memory loss often goes unnoticed so it is important to pay close attention and see if it is normal memory loss or is it an early sign of Alzheimers.

While everyone will forget something once in a while, but Alzheimers sufferer never recall back what has been lost. So pay attention for peculiar incidences of short term memory loss that result in the distress, however much slight, in everyday routine.

Disability

Alzheimers will rob one of the ability to do the things that used to come second nature to them. It is as if the individual with Alzheimers can no longer remember or are familiar with tasks or actions that used to be part of their everyday routine. Watch out for this telltale sale that is quite an indicator included in the early signs of Alzheimers disease.

More Changes

Another early sign of Alzheimers is the increasing problem of communication. Often, people with Alzheimers will have a difficult time communicating because they begin to lose their ability to handle language. They begin to forget simple words and terms and their sentence construction begin to be difficult to understand.

There can also be a change in behavior or mood that is not normal for the person with Alzheimers disease. Over and above moodiness, a person with Alzheimers can switch moods or behavior without reason.
