Hair Removal: The Physics of the Process

Laser hair removal is the most effective and safe method for removing unwanted hair. Laser hair removal is one of the most popular procedures worldwide after non-invasive cosmetic procedures, due to the fact that patients no longer have to worry about removing unwanted hair, enjoying smooth skin without the need to shave or use any other method.

Hair Growth
The laser has the greatest effect on the hair follicle when it is in the active growth phase. There are three phases – Anagen (growth phase), Catagen (transition phase), and Telogen (resting phase). Not all hairs grow at the same time, and therefore, more than one treatment is required to achieve the desired result.

Hair Growth Phases

Excellent Results
The combination of an effective laser device and the highly skilled physician allows for approximately 85-99% hair removal. On average, 5-6 treatments, spaced 8 weeks apart, are required to achieve optimal results. While individual response may vary, results can be accurately predicted by analyzing skin and hair type.

How a Laser Works
The pigment absorbs the energy emitted by the laser, destroying the hair follicle and stopping hair growth. Pigment in the hair follicle is essential for absorption of laser energy, which is why light and gray hair is resistant to this energy. The basic rule is that for hair removal to be effective, the hair must be darker than the surrounding tissue.

Safety
The key to the safety and effectiveness of the procedure lies in selecting the correct operating parameters for the device. This is the optimal balance of sufficient energy to destroy the hair follicle without damaging the surrounding epidermis.

For this reason, doctor training is extremely important. The ability to select the optimal parameters based on individual patient characteristics—skin type, hair thickness, and hair color—guarantees a successful and safe procedure, and ultimately, patient satisfaction.

Timeless Results
The destroyed hair follicle will not regenerate, and the remaining follicles will produce lighter, finer hair, requiring much less attention. Optimal laser treatment, regardless of individual characteristics, guarantees 85-99% hair removal. New hair follicles are formed due to hormonal and age-related changes, as well as genetic predisposition, so some patients prefer annual consultations with a doctor.

Additional Benefits
Some clinical problems are effectively resolved with hair removal equipment—and sometimes, it is the only and most effective treatment. Among other benefits, this means smooth skin free from shaving irritation.

Pseudofolliculitis
Pseudofolliculitis is an inflammation of ingrown hairs that often leads to the appearance of acne-like pustules. Most common in African-Americans, pseudofolliculitis affects both men and women equally and can appear on any part of the body, especially in areas that the patient regularly shaves. Laser hair removal is an ideal solution in this case. By removing unwanted hair from the surface of the skin, we simultaneously eliminate ingrown hairs that cause inflammation.

Hirsutism
Hirsutism is excessive hair growth in both men and women. However, it is a greater problem for women than for men, and the hair is often darker and thicker, including on the face and chest. It’s important to always remember that hirsutism can be one symptom of a more serious problem.
