Laser hair removal is a popular method for reducing unwanted hair, and different types of lasers are used for the procedure. In this blog, we’ll explore the science behind laser hair removal, the types of lasers used for the procedure, and important factors to consider when choosing a laser for hair removal.
The Science Behind Laser Hair Removal
Laser hair removal works by using high-intensity laser beams to target the pigment (melanin) in hair follicles. The laser’s energy heats up the hair follicle, damaging it and inhibiting future hair growth. The number of sessions required and the duration of each session will depend on various factors such as the client’s skin type, hair color, and thickness.
Types of Lasers Used for Hair Removal
The three main types of lasers used for hair removal are Alexandrite, Diode, and Nd:YAG lasers. Each type of laser has its own unique wavelength and target area.
- Alexandrit-Laser emit a wavelength of 755nm and are most effective for treating light skin types with dark hair.
- Diodenlaser emit a wavelength of 810nm and are effective for treating a wide range of skin types and hair colors.
- Nd:YAG lasers emit a wavelength of 1064nm and are effective for treating darker skin types and hair colors.
Important Factors to Consider When Choosing a Laser for Hair Removal
When choosing a laser for hair removal, there are several factors to consider:
- Sprachfluss: Fluence refers to the amount of energy delivered by the laser per unit area. Higher fluence levels can lead to more effective hair removal, but they may also increase the risk of side effects.
- Spotgröße: Spot size refers to the size of the area treated by the laser. Larger spot sizes can cover larger areas more quickly, but smaller spot sizes may be more precise.
- Cooling for Pain Reduction: Laser hair removal can be painful, and some lasers come equipped with cooling systems to reduce discomfort during the procedure. AllWhite Laser devices use Crystal Freeze® cooling tips for virtually pain-free treatments.
- Repetition Rate: Repetition rate refers to how quickly the laser pulses are delivered. Higher repetition rates can lead to faster treatment times, but they may also increase the risk of side effects.
Choosing the right laser for hair removal is essential for achieving safe and effective results. When selecting a laser, it’s important to consider factors such as fluence, spot size, cooling for pain reduction, and repetition rate.
