Keratin Tip Hair Extensions
The full keratin tip category — K-tip hot fusion, I-tip cold fusion, U-tip u-shape bond. Italian keratin polymer across all products, 100% Remy human hair.
The Keratin Bond Extension Family
Keratin tip is the umbrella category for all pre-bonded strand extensions using Italian keratin polymer at the tip. Three flagship products — K-tip, I-tip, U-tip — each solve a different install method challenge. This page maps them side by side and links you to the deep spec page for whichever product fits your salon.
Every keratin tip extension shipped by VeeJeen passes through the same 4-gate QC that every other hair extension on our floor passes. Mixed-SKU orders — tape-in paired with K-tip paired with hand-tied weft — all meet the same cuticle alignment, color tolerance, and shed-rate thresholds, so the salon tech installing them works to one consistent spec rather than product-by-product guesswork.
The keratin tip extension is salon-floor-tested across 400+ accounts in 25 countries. Install times, wear duration, and reinstall cycles that we quote are measured against real salon data from working accounts — not vendor-side laboratory tests. Numbers you can quote to your own salon team without caveat.

Fusion iron melts Italian keratin bond onto natural hair. Longest wear in the category — 10 to 14 weeks per install. Undetectable rolled bond finish.
I Tip
No heat. Silicone-lined micro-beads and loop threader system. Safe for fine, damaged, or heat-sensitive natural hair. 6-8 week wear.

Common QC Across All Keratin Tip Products
Same quality gates apply to K, I, and U tip production.
Cuticle Alignment Verify
40x microscope check on 6 strands per bundle. 100% root-to-tip alignment required or bundle rejects at intake. Verified by 40x microscope on 6 strands per intake bundle; any reversed direction rejects the whole bundle.
Remy Grade Confirm
Cross-check against source ledger. Reject any bundle showing mixed cuticle direction — the signature of non-Remy hair blended in. Full-cuticle Remy, cuticle direction matched root-to-tip across 100% of strands at intake.
Tensile Pull Test
Digital force gauge, 5-strand sample per hour. Threshold >60N single-strand pull to break. Fails trigger station halt. Threshold > 60N per single strand; batches failing twice are reworked and retested, not shipped on waiver.
Spectrometer Color Match
X-Rite Ci64 reflectance spectrometer. Every dyed batch measured against reference swatch to ΔE < 2.0. X-Rite Ci64 unit, calibrated weekly against certified white tile; cross-batch readings archived 12 months.
Shed Weight Measurement
0.01g scale. Comb 50 strokes, weigh loss. Shed rate must stay < 3% of pack weight. Above — reject pack. ± 2% weight tolerance per pack at 0.5g scale resolution; signed QC card inside every pack verifies.
Moisture Content
Gravimetric analyzer at 105°C. Threshold < 12%. Above — re-dry batch and retest before it moves forward. Gravimetric moisture analyzer at 105°C; threshold < 12% content before every pack seal.
Wash Fastness Simulation
10-cycle home laundry rig. No detectable color loss. Fails send batch back to color lab for reformulation. 10-cycle salon wash simulation on retained sample; batches showing any color loss are reworked, not shipped.
Tangle Resistance Test
Dry-comb and wet-comb behavior graded 1–5 scale. Only grades 4 and 5 ship. Standard for every SKU. Dry-comb and wet-comb behavior graded on a 1–5 scale; only grades 4 and 5 ship from the final QC gate.
Pack Weight Verify
Every pack weighed against declared spec. Tolerance ± 2% at 0.5g resolution. Signed QC card inside every pack. Every pack weighed against declared spec, tolerance ± 2% at 0.5g resolution, with signed QC card inside.
Batch Traceability
Every carton labeled with batch number that tracks back through color lot, tying station, and source ledger. Serial batch number per carton; links back to source ledger, color lot, tying station, pack shift.
