Brazilian thread extension is a method of applying strands or extensions (natural hair weaving) that originated in Brazil. That's why it's also called the Brazilian method. It involves attaching an extension to a strand of natural hair with a fine elastic thread, so as to tie them securely together at the hairline like braids.

For a harmonious, natural result, it may be necessary to color, straighten or straighten (for Afro hair) the hair before installation. This elastic thread method is performed in a salon by a hairdressing professional trained in Brazilian thread extension application. The Brazilian method is delicate and time-consuming (around 4 hours). It can be used to add length or volume. Results can last from 3 to 5 months
