Trimming or Shaving of Pubic hair :

During development, pubic hair gradually thickens and may become curly and coarse. Sweat glands are generally found under the hair follicles. These hairs trap the sweat and become a breeding ground for bacteria, causing bad odor.

The armpits and the pubic area are the main area of concern for body odor. These areas are always covered, and the sweat does not dry soon, causing the bacteria to decompose it. So wear, cotton panties and avoid wearing tight & synthetic clothes in warm weather.

Trimming of pubic hair can be done with a small scissors. Shaving can be done by using a sharp blade razor. Shave in the direction of hair growth, to reduce any damage to skin. Apply warm water on hair prior to shaving, which softens the hairs and minimize drag against skin. A blade should be replaced before it starts to irritate skin, particularly in tender and more sensitive areas.

Clean the razor / blade after every use After shaving, rinse the area with either cold or lukewarm water and apply antiseptic lotion. One may get small, red bumps after a day, at few points of hair root. These bumps will disappear in two or three days. Keep the blade & razor separately for your own use only.
