A brazilian hair weave can be a good alternative to synthetic or woven human hair. While synthetic hair can be costly, it offers the same benefits of natural hair and will not require as much maintenance. The only difference between a brazilian hair weave and a natural one is the amount of natural hair. A natural hair weave will last up to six months, and will look as natural as possible. Depending on the style of the braid, it may last as long as ten months.
