Super Double Drawn (SDD) hair is the premium grade of human hair extensions, defined by exceptional length uniformity and consistent full density from root to tip.
How It's Made
"Drawn" refers to the manual length-sorting process. Raw hair is filtered through hackles to remove shorter strands. SDD hair undergoes the strictest rounds of sorting, with more strands matching the full advertised length.
Core Benefits

- Holds curls, waves and precision cuts more evenly
- Retains a dense, luxurious look with long-term wear
