The methods of removing armpit hair can be roughly categorized into two types: temporary hair removal and permanent hair removal. 1. Temporary hair removal: After removing armpit hair by plucking, shaving, waxing, applying depilatory creams, etc., armpit hair will grow back again. In addition, because of the curly growth of armpit hair, the new growth of armpit hair after removal of these methods may irritate the skin, causing pinching or pins and needles sensation; and improper treatment can lead to folliculitis and other skin infections. 2. Laser method can also remove armpit hair, which is based on the principle of selective photothermolysis, so that the temperature of the hair follicle rises rapidly, the tissue is destroyed, and the regenerative ability is lost, so that the effect of removing armpit hair can be achieved, and the effect is better. Generally, after several times of laser hair removal as appropriate, permanent hair removal effect can be achieved. If there is a will to improve, it is recommended to go to a regular medical institution for consultation.
