Brazilian hair treatment deals with natural human hair and very often involves the use of hair dryers and flat irons in order to get the desired style. Human hair extensions are chosen for Brazilian hair treatment precisely to prevent damage to the natural hair and the extensions during this heat treatment. However, this does not mean that a Brazilian hair treatment does not require after-care. The hair installed using Brazilian hair treatment also needs regular bouts of shampooing and conditioning with periodic doses of oil massage, hot oil conditioning and deep conditioning. All grooming procedures for Brazilian hair treatment should be done gently, using only the tips of the fingers to prevent the human hair extensions from slipping or getting damaged. Compared to human hair, synthetic hair cannot be subjected to heat treatment as easily as human hair which has the ability to remain malleable and supple even after intensive treatment. This allows human hair to be used for creating a variety of hair styles using a Brazilian hair treatment. One such hair-style is creating of weaves using the Brazilian hair treatment. During formation of weaves, the extraneous hair is horizontally and vertically braided and the weave pieces are sewn over the cornrow using a thick thread. The thick thread ensures that the Brazilian hair treatment stays stable and firm. The number of weave pieces depends on the length and density desired. A complete Brazilian hair treatment takes 4 to 5 hours.
