SHADE DESCRIPTION:Back to Black. #1 A Deep true neutral black.

Handmade by Us. From Source to Strand.

Our Mini Keratin Bonds are handmade in our facilities we operate ourselves, to our exact specifications and exclusively for Prolonged Hair.

Each bond is individually crafted for discreet placement and natural-looking blending, using the same carefully sourced, cuticle-intact hair as our Genius Wefts. No batch is released until both founders, Jonathan and Whitney Sexsmith, have personally approved it.

No white labeling. No shared production lines. No outsourced manufacturing.

The difference is measurable.Independent blind laboratory testing demonstrated 430% greater tensile strength and 72.6% less breakage compared with leading brands.

Our standards begin with the raw hair. We control our supply chain, oversee every stage of processing, and preserve the hair’s natural cuticle integrity.

Every batch is produced to our specifications, documented, and independently tested.

Our sourcing is backed by documented donor consent and compensation records. We never use silicone coatings or textile dyes.

From raw hair to finished bond, we’re responsible for every step. We don’t purchase finished extensions from a factory’s catalog and put our name on them.

We create every Prolonged Hair Mini Keratin Bond ourselves.

Your reputation is behind every installation. You deserve to know exactly what you’re putting into it.

Professional pricing is available exclusively to licensed stylists with approved Prolonged Hair accounts.

Hand-Pressed Keratin Fusion Bonds

Every Mini Bond is formed and pressed by hand in our manufacturing facility to our specifications. Designed for professional thermal and cold-fusion applications, giving stylists precise control over placement.

What's Actually in the Bond

“Keratin bond” is the industry name for the fusion attachment. It is not an ingredient list.

Our supplier calls the material “Italian Keratin.” Its Safety Data Sheet identifies it as a copolyamide hot-melt adhesive, not 100% pure keratin.

We source the bonding material, then form and press the bonds ourselves.

Discreet, Color-Matched Attachments

Each bond is matched to its hair shade for a discreet attachment that blends into the finished installation. Small, refined bonds keep the focus on your work.

Freedom to Customize Color

Cuticle-intact hair with no silicone coatings or textile dyes. Every shade can be professionally lifted, toned, and colored.

Always strand-test and complete color services before installation. We recommend clarifying the hair before coloring.

Hand-Blended Dimension

Multidimensional shades are blended by hand for natural-looking color transitions. The hair's natural taper creates soft movement, with less preparation required behind the chair.

Precisely Weighted at 0.5 Grams

Each Mini Bond weighs 0.5 grams—half the weight of a 1-gram bond. Designed for fine to medium hair, with greater flexibility in placement, density, and weight distribution.

Ready-to-Install Mini Bonds

Pre-formed and ready for installation. No cutting or reshaping required. Less preparation, more time for the finished look.

Proper care ensures the longevity of the extensions and protects the client’s natural hair.

• Washing: Use sulfate-free, salon-grade shampoo and conditioner. Avoid applying conditioner directly to the bonds.


• Brushing: Use an extension-safe detangling brush daily, starting at the ends and working upward.


• Styling: Always use a heat protectant and avoid direct heat contact with the bonds.


• Sleeping: Braid or loosely tie hair before bed and sleep on a silk pillowcase to prevent friction.


• Hydration: Apply a lightweight oil or cream from mid-lengths to ends daily, morning and night.


• Treatment: Use a peptide-repair mask every 1–2 weeks for optimal strength.


• Swimming: Before swimming, wet hair, apply leave-in conditioner, and braid loosely. Rinse thoroughly afterward to remove salt or chlorine.


• Water Quality: Avoid hard water exposure whenever possible.


• Maintenance Cycle: Move-ups every 8–12+ weeks, depending on hair growth and lifestyle.
