waxing is most popular natural way..for complete removal there is always laser removal or electrolysis..
For most effective waxing and long term effect you can use sugar waxing .This is an ancient method that still used and is better than normal waxing.A paste of sugar ,lemon and water is applied over unwanted hair.
Preparation and direction of use
In a saucepan, combine 1 cup of granulated sugar, 1/8 cup of natural lemon juice, and 1/8 cup of water. Heat this mixture over a medium flame while stirring constantly until the sugar completely melts and turns dark in color.
Begin by lightly dusting your skin with cornstarch. While the facial hair remover is still very warm (bordering on hot), apply it to your skin using a craft stick or popsicle stick while pulling the skin taut. Firmly place a strip of muslin or cotton material over the sugar wax, allow the mixture to cool, and quickly pull it off in the opposite direction of the hair growth. If the mixture was properly prepared, it should pull off any unwanted facial hair.
Store this natural mixture in the refrigerator in a container with a tight-sealing lid. The muslin or cotton material can be washed and reused, and the sugar wax will last for months. This is one of the best ways to remove excess facial hair. It's cheap, easy, and completely natural.
