Shave underarm hair. Treat any skin condition that may be present in the underarms. In certain cases, your doctor may prescribe antibiotics you can apply to the area. Certain food, drugs, and drinks. Start using deodorant, cologne, or perfume. Thoroughly washing your skin with a wet washcloth and soap -- especially those areas prone to sweating.
Shower every night or morning and make sure to apply deodorant after your shower. Another tip is to got to the store and buy a travel size deodorant then you could put it in your backpack, locker, etc.
