Laser hair removal inquiry

Hello. I am an office worker planning to get laser hair removal treatment for neat and convenient hair management in preparation for the upcoming summer. Since I always shave at home, my skin easily turns red and I frequently experience skin problems such as folliculitis. Therefore, I have started looking into professional clinic treatments that offer safer and semi-permanent results.

The laser hair removal treatments are performed on the underarms and calves, and I have heard that results vary depending on individual hair thickness and growth rate. I understand that it is generally most effective to schedule treatments in accordance with the hair follicle growth cycle; I would like to know approximately how often I should schedule my visits. Additionally, please let me know the recommended total number of sessions required to achieve noticeable, permanent results.

Finally, I would appreciate it if you could also answer whether you possess pain-free and hygienic air-impact laser equipment, such as the recently introduced Apogee Plus or GentleMax Pro, and whether there are any precautions I need to take on the day of the procedure.
