Body hair growth is a natural biological process that plays various functions in our body, including temperature regulation and skin protection. Hair removal has become extremely popular in recent years, and many people are looking for methods that will remove hair for a long time or even completely. Completely and permanently eliminating hair growth all over the body using methods such as laser hair removal is possible, but results may vary from person to person. In this article, we will look at the possibilities of completely eliminating hair growth, especially in the context of laser technology and other methods.

Laser hair removal - how does it work?

Laser hair removal is one of the most effective methods of hair reduction. It works by emitting intense light, which is absorbed by the melanin (dye) in the hair. The light energy is transformed into heat, which destroys the hair follicles, inhibiting their ability to grow again. A key factor in the effectiveness of this method is that it works best on hair that is in the anagen, or active growth phase.

Can laser hair removal remove hair completely?

Although laser hair removal can significantly reduce the amount of hair, complete hair removal over the entire body is very difficult to achieve in practice. The main reasons are:

• The different phases of hair growth - body hair goes through three phases - anagen, catagen and telogen. The laser is mainly effective in the anagen phase. As only part of the hair is in this phase at any given time, a series of treatments is necessary to cover all hair in the correct growth phase.
• Individual differences - each person has a different hair growth cycle, which affects the effectiveness of the treatments. People with darker hair and lighter skin usually achieve better results, as the greater contrast between skin colour and hair makes it easier for the laser to identify and remove them (the laser absorbs melanin better).
• The ‘wake-up’ phenomenon - After a series of treatments, some hair may re-grow, especially if it was in the catagen or telogen phase at the time of the treatments. This phenomenon, known as hair ‘awakening’, means that some people may notice hair regrowth after a period of time. Therefore, several sessions (4-8 or more) are usually needed to achieve lasting results, but maintenance treatments may be necessary every few months or years.

Laser hair removal does not always eliminate hair completely. Usually, a significant reduction in hair growth is observed (80-90%), but in some people, individual, thin hairs may appear, which grow back.

Other methods

1. Electrolysis is the only method approved by the FDA for permanent hair removal. It works by inserting a thin probe into the hair follicle and destroying it with an electric current. Electrolysis works on all hair colors and skin types, unlike lasers, which work best on dark hair. Hair destroyed by electrolysis does not grow back, but because hair grows in different phases (anagen, catagen, telogen), multiple sessions are necessary to permanently remove all hair from a given area. This method is very time-consuming, especially on large areas of the body, because each hair must be removed individually.
2. Intense Pulsed Light (IPL) - IPL technology is similar to laser, but uses a broad spectrum of light with different wavelengths. It is less precise than laser. IPL works best on people with light skin and dark hair, similar to laser. It may require more sessions than laser, and the effects are not always as long-lasting. IPL can significantly reduce the amount of hair, but like laser, it requires maintenance treatments.

Is there complete hair elimination?

Although modern hair removal methods, such as laser or electrolysis, can significantly reduce the amount of hair and delay its regrowth, the complete elimination of hair growth on the entire body is still not achievable. Many factors, such as genetics, hormonal changes in the body and even lifestyle, can affect hair growth. For those with intense hormonal hair growth, such as women with polycystic ovaries (PCOS) or hirsutism, hair elimination can be even more complicated, time-consuming and less effective.

Summary

Although available hair removal methods, such as laser hair removal and electrolysis, can significantly reduce the amount and thickness of hair, complete elimination of hair growth on the entire body is currently not possible. Hair will always grow back, but with advances in technology, it is possible to significantly extend periods of smooth skin and minimise the amount of unwanted hair. It is also crucial to understand your individual needs and choose the right hair removal method that best suits your expectations and skin type.
