Our Brazilian Virgin Hair is one of the best types of hair extensions in the world. Brazilian Virgin Hair is naturally compatible with most hair types including African-American and Caucasian. 10A and 8A are both 100% virgin human hair and has not been processed in any way, free of any hair color. The only difference is the donors for the 10A never use hair products with chemicals like gel or shampoos with sulfur. Both are great quality but the 10A hair is the best hair on the market. 10A hair can last up to a year with proper care and the 8A hair can last up to 6 months with proper care.
