In professional hair manufacturing, density is not defined by weight alone. Instead, it is determined by the percentage of strands that share the same length within a bundle. The higher this ratio, the thicker and more uniform the hair appears from root to tip.
This distinction becomes especially important when comparing super double drawn hair and premium hair extensions, as both offer full-looking ends but differ in internal strand composition and production cost.
Super double drawn hair is processed through advanced sorting to ensure that approximately 80–85% of the strands are the same length. Shorter hairs are removed to create a consistent thickness throughout the bundle, resulting in ends that appear full and balanced.
From a visual standpoint, super double drawn hair delivers:
A head-to-end thickness that looks nearly identical
Natural yet dense ends
A clean and professional installation finish
For most salon services, the difference in thickness between the root and the tip is minimal, making super double drawn hair an excellent choice for both everyday and premium installations.
In wholesale terms, super double drawn hair wholesale orders offer one of the best balances between density, performance, and cost efficiency.
Premium hair extensions represent a higher density tier, with more than 85% of the strands sharing the same length. Achieving this level of consistency requires significantly more raw hair and more intensive manual sorting, which directly increases production costs.
Premium hair is characterized by:
Extremely blunt, thick ends
Maximum fullness from root to tip
Minimal visible taper
While the visual difference between premium hair and super double drawn hair can be subtle at first glance, the internal strand ratio is higher in premium hair, resulting in slightly heavier and denser ends.
In real-world salon applications, super double drawn hair and premium hair often appear nearly identical once installed. Both offer:
Full ends
Consistent thickness
High client satisfaction
The main difference lies not in what the client immediately sees, but in the percentage of long strands inside the bundle. For most hairstyles, especially when layered, styled, or blended, the additional density of premium hair does not create a dramatic visual advantage over super double drawn hair.
Because premium hair requires more raw material to achieve a higher strand-length ratio, it comes at a significantly higher price point. For wholesalers purchasing in volume, this price difference becomes substantial.
At NASA Hair, we often advise wholesale buyers to carefully evaluate their market positioning. For the majority of salons and distributors, super double drawn hair provides virtually the same visual density at a much more competitive cost. This allows buyers to maintain strong margins without compromising on appearance or quality.
For wholesale buyers focused on consistency, scalability, and cost control, super double drawn hair is usually the most practical choice. It delivers:
80–85% long strand ratio
Near-equal thickness from root to tip
Excellent performance across most salon services
Premium hair is best reserved for highly specialized markets where clients explicitly demand the highest possible density and are willing to pay a premium for marginal differences.
The choice between super double drawn hair and premium hair extensions is not about which option is “better,” but which one aligns with your business model. While premium hair offers a higher strand-length ratio, super double drawn hair wholesale orders often provide the optimal balance of appearance, performance, and cost efficiency.
Understanding strand ratios and end density allows wholesalers and salon owners to make smarter purchasing decisions — and build a more sustainable hair extension business.
