The laser hair removal procedure consists in a permanent reduction in the removal of unnecessary hair with the help of light beams. We explain what laser hair removal is, how it affects the hair on the body and how exactly the procedure itself takes place, along with the preparation for it. We will also try to discuss all the advantages of this method and explain why it is not only the most effective but also burdened with the least number of possible complications depilation procedures.
What is laser hair removal?
Laser hair removal provides permanent damage to the hair follicles. The light beam emitted by the laser beam is absorbed by melanin, a colour found in the hair. Photothermolysis takes place, i.e. the pigment found in the hair heats up to such an extent that the high temperature which damages the hair follicle and leads to its destruction. Thanks to this, the hair does not have the opportunity to grow back in this place, and under the skin, there is no other bulb in the same place.
Due to the fact that the natural component of our body, i.e. melanin, is important in the whole process, laser hair removal treatment is more effective in people with darker hair. The more melanin pigment in the hair, the higher the temperature caused by the laser light beam, and therefore the greater the damage to the hair follicle. The temperature that is generated is targeted the melanin in the hair and the surrounding tissues are not impacted. This is due to the chromophore which is known as the target for laser hair removal. The chromophore for laser hair removal is the melanin in the hair. The surrounding skin is not affected by the laser beam due to the wavelengths just attracting the melanin in the hair.
What are the advantages of laser hair removal?
The biggest and undeniable advantage of laser hair removal is its durability. No other method damages the hair follicles so effectively and permanent reduction. In this case, the need to repeat the treatments is dictated only by the amount of melanin contained in the hair – in the case of light shades, especially blonde, there may be a need to re-treat the hair bulbs with a beam of light to completely destroy the unwanted hair follicle. An additional great advantage of laser hair removal is the complete removal of the problem of ingrown hairs and inflammation arising around the hair follicles.
This is one of the methods of hair removal, which has a very small range of contraindications. These are primarily psoriasis, ichthyosis, herpes, warts and vitiligo – due to the local lack of melanin, which prevents the proper functioning of the light beam. Laser hair removal is also not recommended for pregnant and lactating women. The good news for people suffering from varicose veins is the fact that the laser hair removal is completely safe, because its action is directed only at pigment cells and does not affect in any way the inefficient veins.
Preparation for the procedure and its course
Laser hair removal is always preceded by a patch test that will allow the Aesthetic practitioner to observe the skin and hair including skin typing Fitzpatrick skin type and hair density, but above all it gives the opportunity to assess whether the client has any visible contraindications to perform the procedure. The initial visit is also a time to discuss the area of the body that you will have laser hair removal procedure and to choose the most appropriate device.
On the day of the procedure, the selected area should be thoroughly shaven with a razor so that the light beam does not burn the hair protruding above the surface of the skin and focuses only on melanin compact in the part that fits in the hair bulb. In the case of laser hair removal of the most delicate parts of the body, for example, intimate zones.
Before laser hair removal procedure you should avoid any hair removal which removed the hair from the follicle, such as waxing, epilating and plucking. The hair needs to be shaven and in the follicle for the laser beam to penetrate deep down in the hair bulb and hair follicle. Avoid use of chemical peels including AHA, BHA and any products that contain vitamin A should be avoided.
For at least a month, you can not sunbathe a given area of the body, both in the sun, on the sun beds, and with the help of self-tanning cosmetics. Experts recommend refraining from performing mechanical peelings in the period of about a week before the planned procedure.
When does hair fall out after laser hair removal?
Laser hair removal – after what time does hair fall out? You are probably wondering whether the thermolyzed hair disappears immediately after the procedure, or whether the body gets rid of them for some time. Due to the mechanism of action of laser hair removal, which does not annihilate the hairs themselves, but only the place from which they grow, the liquidation process is not as rapid as, for example, after using wax, when the effects can be seen already during the peeling off of the patch, it is also not very long.
After thermolysis, the hair part, located in the skin, slowly moves upwards, thanks to the constant work of the skin, which moves with each of our movements. After all, when the bottom of the hair reaches the level of the epidermis, it falls out. This can take about two weeks, but it depends on the place where the procedure was performed. Hair shedding varies from person to person.
Hairs that have been shaven are inevitably come through the skin which is normal. This does not mean that the laser hair removal procedure has not worked. The final effect of laser hair removal will be visible after less than a month, then there will be the most appropriate moment to book for the next treatment, aimed at eliminating the remaining hair follicles. Until the end of a series of laser treatments, do not use mechanical epilators or wax, but you can safely shave your body with bladed shavers.
The hair shedding or fall out for each individual varies, do not be alarmed if you have no hair fall out or the hairs grow back after a few days after the first session. This is normal, the hair growth is the hairs that were shaven, you can shave these hairs and then after this period, you will notice that the hair has become patchy and some patches will become hairless.
