Different Types of Hair Bundles: Understanding SD, DD, and SDD
When shopping for hair extensions, it is important to know the different types of hair bundles available. Here we explain the differences between Single Drawn (SD), Double Drawn (DD), and Super Double Drawn (SDD) hair bundles.
Single Drawn (SD) Bundles
SD bundles consist of 50% longest length hair and 50% shorter length hair. For example, a 20″ bundle will have 50% 20″ hair, 25% 18″-16″ hair, and 25% 16″-14″ hair. This results in a thinner bundle, making it best suited for shorter lengths up to 12″.
Double Drawn (DD) Bundles
DD bundles consist of 70% longest length hair and 30% shorter length hair. For example, a 20″ bundle will have 70% 20″ hair, 20% 18″-16″ hair, and 10% 16″-14″ hair. This results in a medium-full bundle, making it ideal for lengths from 12″ up to 18″.
Super Double Drawn (SDD) Bundles
SDD bundles consist of 90% longest length hair and 10% shorter length hair. For example, a 20″ bundle will have 90% 20″ hair, 5% 18″ hair, and 5% 16″ hair. This results in a very full bundle, making it suitable for lengths from 20″ up to 40″.
