How do laser hair and IPL removal work?
Both laser and IPL hair removal are increasingly popular methods of hair loss. Alternative hair removal methods (such as waxing and threading) are gradually increasing in price and have unpleasant side effects such as ingrowth hair. Laser and IPL treatments produce fantastic long-term effects without the unpleasant and painful side effects of other hair removal techniques.
What is it?
IPL stands for Intense Pulsed Light, and laser hair removal machine is both a long-term and permanent method of reducing hair. They involve the use of a beam of light on the skin that targets the areas of high pigmentation that heat them to the extent that they destroy the hair follicles. This inhibits hair growth, shrinks the hair follicles and ultimately leads to loss of hair growth in the area.
How does it work?
A beam of light is directed onto the skin. Light energy is absorbed by areas of high pigments (such as hair) where it is transmitted as heat. Heat heats the hair and destroys the hair follicles. Then the follicles cannot grow new hair.
This is because energy is absorbed by the most pigmented areas, and IPL and laser hair removal are most effective for people with dark and fair skin. In these people, the hair contains more pigment than the skin, so it absorbs the lightest energy and is therefore heated most.
IPL and laser hair removal
IPL and laser hair removal are based on the same principle. The main difference is the light on the hair. A laser is a focused beam whose characteristic means that it can be concentrated in a narrow area, and unlike light, it does not widen over long distances. The light on the laser beam has a very narrow spectrum, so only a single color can be released. On the other hand, conventional light cannot be narrowed and will be farther away from the distance they travel. The beam also contains a wider range of colors.
Diode laser hair removal utilizes these characteristics of the laser to direct the beam directly down into the pores, directly targeting the hair follicle, while the light used in IPL hair removal spreads over a wider area. Both sources heat the hair follicle to cause damage, but laser hair removal is more specific and may require less treatment to achieve the same effect.
How many times do I need IPL or laser hair removal?
For each person and different areas of the body, hair grows at different rates. Therefore, different people and treatment areas will require different numbers of sessions to achieve satisfactory results. Some people find that only one session is enough, while others need ten sessions.
You are likely to need multiple treatments because the hair does not respond to laser or IPL at all stages of the growth cycle. They are the fastest in the initial phase and are called anagen. This is called melanin when they are actively growing and contain the most pigments. The more pigment they contain, the more light they absorb, the higher the temperature at which they are heated. Higher temperatures mean better destruction of the hair follicles and therefore more successful treatment.
Where can the body use IPL and laser hair removal?
Women can perform laser hair removal in most areas of the body, including the face below the cheek line, underarms, bikini/Brazil lines, and legs. Men can also do it, including in the back and chest areas, but should not treat their facial hair because the hair is too dense. Men and women should not receive scalp treatment and should not treat nipples or genitals.
Is IPL/laser hair removal permanent, or is hair coming back?
Laser and IPL hair removal can be very effective, and studies have found hair growth to be reduced by 60%. However, unfortunately, no hair removal method is completely permanent, but laser and IPL hair removal can achieve good results. It destroys the hair follicles and keeps the hair from growing. The grown hair will proceed at a slower rate and is usually thinner. After completing the treatment plan, you may need to perform maintenance/recharge sessions occasionally to stay in top shape.
