Laser hair removal is one of the techniques that have revolutionised the beauty sector the most. Currently, it is a very widespread treatment, which is carried out in many salons and beauty centres, although, according to personal injury legal experts, not always by qualified personnel, nor with the safest and most effective equipment.

Here, we clarify everything you need to know about laser hair removal and what myths exist behind this medical-aesthetic protocol that should only be done under supervision by a qualified professional.

Laser hair removal consists of the application of a very intense and selective light that has the peculiarity of crossing the structures of our body without damaging them and concentrating all its energy on those structures of the skin that have the colour black, like the hair root that it is growing (selective photothermolysis). The laser results in its destruction.

Here is what is true and false regarding the most popular beliefs about laser hair removal:

  1. Laser hair removal is a method that can damage the skin and is less safe than other traditional systems.

In fact, laser hair removal, in expert hands, is a safe method that removes hair and does not damage the skin. It is based on the principle of selective photothermolysis, through which the hair follicles (which are the target) are destroyed without damaging the other neighbouring structures. It must also be borne in mind that laser hair removal is not a radiation that accumulates in the body, and therefore has no consequences or repercussions on general health in the short, medium or long term.

  1. Laser hair removal is the same as other methods and does not completely eliminate hair.

In fact, numerous studies show that laser treatment permanently removes and destroys hair in a high percentage of cases, and in the vast majority of patients. Only a long-term maintenance session is necessary to finish eliminating any residual hair that may remain. Later the hair grows more slowly, it is thinner, lighter and less abundant.

  1. Laser hair removal is a painful treatment.

In fact, laser hair removal is a soft and highly tolerated treatment. There is only a slight and temporary sensation of heat that is attenuated by a cold air system. In exceptional cases and with a lot of sensitivity, a local anaesthetic cream can be applied to avoid discomfort.

  1. Laser hair removal is an expensive treatment.

In fact, this method of hair removal is more economical than others if we analyse it in its entirety. The investment depends on the extension of the area to be treated, but it is certainly less than the total sum of the cost of all traditional hair removals, with the time savings that this entails.

  1. Not all areas can be treated with laser, especially the most sensitive areas.

In fact, it is not true, any area of ​​the body that has the appropriate hair is capable of being treated with laser (legs, groin, armpits, arms, back, facial area, etc.) and is especially useful in those areas intolerant to traditional hair removal such as spots, folliculitis, cysts, etc.

  1. Fine or blonde hair cannot be removed with laser hair removal.

In fact, it is always recommended to make a prior assessment of the patient, to verify if the hair has enough melanin charge to be treated. Whenever it is a fine hair and black or chestnut colour, you can use laser hair removal, although it may require a greater number of sessions due to its lower melanin content. If it is very blond or white hair, it will not be possible to treat with laser.

  1. Laser hair removal is the same in all centres.

In fact, laser hair removal is not the same in all centres. In recent years places have been appearing that offer laser hair removal treatments performed by very low-qualified personnel at very low prices, working with sub-standard devices. Not going to specialised centres can be counterproductive considering that, in laser hair removal, you have to adapt the beam parameters to the type of hair (black, brown, blonde, etc.) and skin type (phototype) mainly to not obtain the opposite effect of stimulating more hair growth. A fact that is becoming more common, as evidenced by the increase in beauty treatment claims in connection with laser hair removal treatment, is that the lasers used in some centres produce burns or some side effects on the surrounding structures (such as skin), because it takes an excessive time to find the right dose for hair removal.

  1. It does not matter if you sunbathe before laser hair removal, the problem is later.

In fact, although it is known that after the session of laser hair removal it is important that the treated area is well protected with sun protection, it is not advisable to be exposed to the sun (or to tanning cabins) for at least four or five weeks prior to the laser session, nor can you use self-tanners.

  1. Before each session of laser hair removal, you need to shave the hair.

In fact, before laser hair removal it is recommended not to shave the area to be depilated in order to verify with accuracy the extent of the surface to be treated. Neither should you use tweezers, wax or epilating razors, as they pull the hair by the roots and this will decrease the effectiveness of the treatment.
