For men, abundant body hair can be a symbol of charm and strength. However, it's undeniable that excessive hair growth can lead to issues like folliculitis, ingrown hairs, and excessive body odor.

This article will focus on the following topics that men should understand before undergoing laser hair removal:

1. How laser hair removal works？
2. What differences in hair removal concerns between Men and Women？
3. Choosing between salon-based or at-home hair removal device？

According to Mayo Clinic Press[1], laser hair removal works by directing a concentrated beam of light onto areas of the body with excess hair. The light is absorbed by the hair's own pigment or melanin. This light beam heats the skin, damaging the hair follicles in the skin, preventing them from regrowing hair or significantly delaying the growth process.

"Due to testosterone, men tend to have thicker and denser hairs than women do and may require more treatments," notes Dr. Emily L. Guo, a board-certified dermatologist at Dermatology & Laser Surgery Center in Houston.[2]

Therefore, we can conclude that men may require more frequent sessions or higher energy levels for effective laser hair removal.

Yes, laser hair removal can be done indoors and easily at home with a small handheld laser hair removal device.

However, these smaller devices typically have lower energy levels compared to the commercial equipment used in salons, so they may require more frequent use.
