The non-ablative Er:YAG laser is used to prevent hair loss and stimulate hair growth.
It is most commonly used as a therapy for androgenetic alopecia, but it has also proven effective for other forms of alopecia. It works through photobiomodulation mechanisms, stimulating cellular metabolism, while the photothermal effect stimulates tissue regeneration. The laser improves blood circulation in the scalp, especially in the area of the dermal papilla, and affects the hair growth cycle by encouraging the transition from the telogen to the anagen phase. The result of this action is a thicker hair shaft and increased hair density.
A major advantage of the Er:YAG laser is that its laser beam is absorbed in the superficial layers of the skin, while heat diffuses into the deeper layers. This mechanism of action makes the treatment extremely safe.
In 2024, we published the results of our study on laser stimulation of hair growth using the Er:YAG laser in the ISHRS scientific journal Hair Transplant Forum International.
Laser treatments are performed at two-week intervals, and a total of six treatments in one cycle is recommended. The treatment lasts about 20 minutes, is painless and does not require anesthesia. During the procedure, warmth or mild tingling may be felt in the areas where the laser is active. The procedure is performed using a special comb-shaped attachment (X Restart), which is gently passed over the scalp.
Results are most often visible after just a few months.
