How Lasers Work in Laser Hair Removal

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 a Laser Hair Removal Clinic

You want to take proper precautions when searching for a laser hair removal clinic. Some may believe if the clinic offers the procedure, they must know what they are doing. This is not always the case at all.

You want to be sure the practitioner is highly qualified to perform laser hair removal. Having an unqualified one could result in an improper procedure and an unhappy client; you.

If you think you have found a great place after only checking out one or two, look again. You want to have as many options to choose from. You want to do the extensive research of places like you would for a doctor.

After you do the research, visit the places most appealing to you. Find out if they give free consultations. Have questions ready when visiting a laser hair removal clinic. Ask them any and all questions you might have. Remember, no question is dumb!

Knowing the types of lasers they use is beneficial to you. The more you study about the lasers the more you will understand how the procedure works. Find out how long the practitioner has been in practice for laser hair removal. How many procedures has he done?

You can find a clinic using your local yellow pages or doing a search online. IF you do not mind traveling to a clinic, you could do an extensive search. You might find one you prefer the most at a location other than your own town.

When visiting a laser hair removal clinic, remember to take notes on your surroundings. Do they keep the place in clean condition? Are the people helpful and friendly? Go with your instincts on the way the place in general makes you feel. You want a clinic that you are comfortable being in. Also ask to meet the laser hair removal practitioner if possible.

If not, ask if they offer free consultations. If they do, make an appointment to meet with the practitioner. Laser hair removal is something to be carefully considered just like any other similar procedure.

Think of any questions you can before you have your consultation. Write them down in case your practitioner does not cover them all with you during your consultation. Find out how much it is going to cost you, how many sessions you are going to have. Also ask what type of side effects you could experience.

Depending on the patient having laser hair removal done and the area they choose, the side effects could easily differ. Just knowing what you might expect will make you feel more comfortable. Ask about the procedure and how it works. Can you expect to feel much pain?

How many times have they performed laser hair removal? How effective have the results been? What kind of lasers do they use? No question is too dumb when it comes to laser hair removal. You want to know all you can before proceeding with a laser hair removal treatment.

An Overview of Laser Hair Removal

Laser hair removal is an excellent way of removing unwanted hair. This is accomplished by sending a light beam of a specific wavelength onto the skin from the laser. The beam of light is sent through a hand piece into the skin, where it attacks the darker pigmentation of the hair follicle. This causes damage and destruction of the hair follicle without damaging the skin tissues around it. Some people do experience permanent hair loss, while others do need to repeat the procedure. Sometimes when hair does grow back it is lighter in color and finer and texture.

There are four types of lasers that are used for hair removal. They are Ruby, Alexandrite, Diode, and NdYAG. Each of these four lasers are different in many ways and are used for different skin types. The ruby laser is able to focus in on small areas and can be used on both dark and light skin. However, this laser works best on light skin. The alexandrite laser is very versatile and can be used on many different types of hair. It is able to focus on large areas and is very easy to customize. The diode laser uses a much longer wavelength which makes it very effective on most types of skin. The NdYag laser works well on people with dark hair and dark skin.

Laser hair removal is not a good treatment option for everyone. It is not recommended for people with certain medical conditions or disorders. It also is not an effective treatment for people with white, gray or very light-colored hair. People that have hair of these colors do not have pigments in their hair to absorb the energy from the laser. Laser hair removal works about system on people with light skin and dark hair.

In some instances, such as the removal of facial hair, one treatment may be enough. In other areas of the body, often a series of treatments must be given to remove the unwanted hair. Many times, laser hair removal is the last resort for people after years of using other methods to rid themselves of the excess hair.

Although laser hair removal is considered safe, it is important to have your treatments done by an experienced, licensed professional. If the treatments are not done correctly, you run the risk of burns, blistering, skin discoloration, or a patchy uneven hair regrowth. Take the time to meet with several specialists in your area, and then decide which one is right for you. For the best results follow all the guidelines that your doctor gives you both before and after your laser hair removal treatments.

The cost of laser hair removal can be expensive, and since it is considered a cosmetic procedure, it is not covered by insurance. Generally, a payment plan can be arranged for treatments. The average cost per treatment for laser hair removal in the United States is between $425 and $500 and many people need three to four sessions.

Laser hair removal is an excellent alternative to other types of hair removal and should seriously be considered by those who are troubled by excessive hair growth.

What You Should Know about Laser Hair Removal

Are you considering laser hair removal? If so you should read on to find out what you should know before deciding. Something like this is a rather major change. You want to know all the facts before you commit to something such as laser hair removal.

Are you eligible for laser hair removal? If your hair is darker than your skin you might be okay. It is not recommended that any person tanning with dark hair do this. If you are tanning, you will have to wait until your tan fades. Then you can proceed with laser hair removal. If you tan but have light hair, it is not recommended for you.

If you are dark skin you might not want to do it. The pigments in your dark skin will absorb laser energy. The darker your skin is the harder it is to perform laser hair removal. You will have to have more treatments and this will make the cost go up as well.

You can treat most areas of the body. The main areas are: Neck, Chest, Underarms, Back, Abdomen, Bikini Line, Legs and Face. You cannot have laser hair removal anywhere around the eyes. The laser is harmful to your eyes so you should wear eye protection during the treatments no matter what area you have done.

Know your options to laser hair removal. You could continue shaving, tweezing, bleaching or even waxing. While these may not sound as great, they might be better for you. The lasers produce highly concentrated beams of light that will penetrate your skin and find your hair follicle. This will produce a hot heat and damage the follicles, preventing them from future growth.

When preparing for laser hair removal you do not want to use any other type of hair removal product. That means no tweezing or waxing or anything similar. The laser hair removal will be hard to perform if there is no hair there to remove!

You also do not want to tan or moisturize. If you tan the laser could burn your skin and if you moisturize it could block the laser energy and maybe even give you an allergic reaction. Avoid both of these at all costs!

How much can you expect to spend? It will vary depending on your location and laser hair removal facility of course. According to a 2000 survey of ASAPS the average cost per treatment (one) for each of the following regions was:

Midwest: $497
East: $458
South: $307
West: $469
National Average: $360

Contact your local laser hair removal clinic to find out the costs. If they happen to be a bit too high for you check the closes surrounding laser hair removals clinics. Maybe they are a bit more in your price range.
Keep in mind when doing laser hair removal that it does not mean one hundred percent of your hair will be gone. Each person is different and some may require more treatments than others. You will definitely see a significantly reduced amount of hair.

You might end up with a type of sunburn like reaction after laser hair removal. You could even have blotches, discoloring, blistering and scarring and even crusting or scabbing. Talk to your professional to find out if laser hair removal is right for you.
