Electrolysis vs Laser Hair Removal, Which Is Best?

Electrolysis vs Laser Hair Removal

Electrolysis vs Laser Hair Removal – Electrolysis Hair Removal refers to the practice of removing hairs from the human body through electricity. When hair is removed in this way, the effects are almost always permanent. In the United States, electrolysis hair removal is the only method of permanent hair removal, which is approved by the Food and Drug Administration (FDA). It involves several steps or treatments to be completed and is done by inserting a needle probe into a hair follicle and passing an electric current through it. Any area of the body except the inside of the nose and ears can have the hair removed in this way. Electrolysis Hair Removal may be an alternative to laser hair removal.

Electrolysis vs Laser Hair Removal, Which Is Best?


There are three basic methods of electrolysis hair removal. The former is known as galvanic electrolysis and causes an area of damage to the hair follicle, forming a small amount of chemical sodium hydroxide, a harsh chemical used to make soap and dye removers from clogging. The damage done is just enough to prevent the hair follicle from growing again.

The second common method is simply to overheat the hair follicle in a technique called thermolysis. The blending method combines the first two to achieve the same result in a short period of time. This term can be reduced quite valuable since electrolysis hair removal is a notoriously time-consuming process. The electrolysis needle should remain in the hair follicle for up to one minute, and all hairs should be removed that way. Even a small area can have a total of hours, depending on the amount of hair there is to be removed.

The tedious nature of electrolysis hair removal can be its biggest drawback, aside from the cost, which is usually anywhere from several hundred to several thousand US dollars (USD). It also requires that the patient have various treatments, no matter how much or how little hair is being removed, because of the cyclical way in which hair grows from its root. Localized redness and swelling are common after the procedure. Scabbing and skin discolorations are possible in the short term after the procedure as well.

Despite these disadvantages, electrolysis hair removal continues to be the most effective form of permanent hair removal available. It is also capable of benefiting a wider range of people than laser hair removal. For example, while certain skin colors may prevent some people from having done laser hair removal, electrolysis hair removal targets the hair follicle instead of hair pigment. This means that people with any type of skin or hair can use this treatment. –¬†Electrolysis vs Laser Hair Removal


Care In Professional Choice

Electrolysis vs Laser Hair Removal – The esthetic professional must have full control of the electrolysis technique in order to safely perform it, avoiding problems such as:

  • Penetration of the needle beyond the root does not cause destruction of the bulb and insufficient penetration may cause a burn superficial;
  • Over-discharge time may cause burns to the skin;

The intensity control should be in accordance with the resistance of the hair, but the sensitivity of the skin must be respected so that no scars remain.


Laser hair removal is a technique of progressive removal of hairs made through the laser light energy. The first laser hair removal devices came in the 1970s, but this technology was at first ineffective, very painful and limited. However, in 1983, Anderson and Parrisch introduced the concept of selective photothermolysis (used in laser hair removal ), revolutionizing the physical principle of the laser mechanism, leading to greater effectiveness. Today there are different types of laser capable of promoting progressive hair removal.

Laser hair removal can be done by anyone who is uncomfortable with their hair or with other methods of hair removal with wax and razor blade. There are special indications for cases of pseudofolliculitis (by ingrown) in the groin, which ends up staining the region, such as the face, legs or any other region of the body.

In general, white skins with thick, dark hairs respond better to laser hair removal, but that does not mean that those who do not fit these characteristics cannot do laser hair removal. Over the years new technologies have been created, even black or tan skins can do. Dermatologists recommend the use of Diode and ND YAG lasers with a long pulse for these cases. The exception is for those with white, red and blond hairs – as the melanin amount is small, there is still no good response to treatment for these cases, but they can be treated, they only need more sessions.
We usually start doing laser hair removal as soon as it is uncomfortable for the person, even in cases of pre-teens. There are cases reported in the literature on the use of laser hair removal in younger children who had congenital hypertrichosis (which is abundant for genetic reasons) in the lower part of the back (lumbosacral region).

The laser is great for treating larger areas. The latest type available in Brazil is the diode laser (red rays) and promises to wipe the hair from the third application. For now, the disadvantage of the laser has been the cost: about ten times more expensive than the electrolysis. –¬†Electrolysis vs Laser Hair Removal


Post-Treatment Care (Electrolysis and Laser)

  • Avoid sun exposure and makeup for 12 hours
  • Avoid manipulating the skin
  • Washing the area with antiseptic soap
  • Apply daily healing gel with sunscreen
  • Do not use greasy creams
