Another function of armpit hair is that when the human body moves, the arm moves with it, and there is always friction between the armpit and the surrounding skin. If the friction is too long and too heavy, it will often be rubbed in the "middle" to reduce the skin friction and protect the armpit skin from being scratched, so the role of armpit hair is undeniable. Many women often pull it out or shave it off for beauty, which is harmful to their health. Because axillary lymph is rich, pulling or shaving axillary hair is easy to cause epidermal infection and cause hidden dangers.
Therefore, the correct way is to trim with round-headed scissors, which is beautiful and will not scratch the skin.
