Product Introduction

Maximum Bond Surface for Maximum Hold

U tip solves the "not enough bond contact" problem in fusion install. The pre-formed U-shaped keratin bond wraps around a section of natural hair, doubling the surface area of contact compared to K tip. Best fusion method for thick, coarse, or resistant hair.

Every U-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 U-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.

How It Works

U-Shape Wrap Install Workflow

The U-bond wraps around a section of natural hair before fusion iron activates the keratin.

Stage Ⅰ
Ⅰ

Section Hair

Part hair horizontally into thin sections.

Stage Ⅱ
Ⅱ

Position U Bond

Wrap U bond around natural hair section. Peel adhesion verified > 8N/25mm per batch; batches failing tests are reworked, not released.

Stage Ⅲ
Ⅲ

Fusion Iron

Clamp iron at 140°C for 2-3 seconds.

Stage Ⅳ
Ⅳ

Roll Wrap

Roll melted bond into secure wrap.

Stage Ⅴ
Ⅴ

Cool & Style

Let bond set 30 seconds. Blend hair.

Production & Quality

How Every Pack Is Built

Documented QC from raw material intake through sealed pack.

CxIntake Gate

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.

ReIntake Gate

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.

TsAssembly

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.

ΔEColor Lab

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.

ShAssembly

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.

MoIntake & Pack

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.

WfPost-Color

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.

TgFinal QC

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.

PkPack 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.

BtFinal QC

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.

Product FAQ

U Tip Buying Questions Answered

Q1What is a U tip hair extension?
U tip is a pre-bonded hair extension with a U-shaped keratin bond that wraps around a section of natural hair before fusion iron activation. The wrap-around design doubles bond surface area compared to K tip — strongest hold in the fusion category.
Q9How do you prevent color drift across large multi-batch orders?
Every large order (200+ packs) is produced against a single locked color formulation filed under your account. Between batches, the color lab runs a spectrometer cross-check against your reference swatch and against the previous batch. Cross-batch tolerance is ΔE < 1.5. Any batch outside that range is reworked before it moves to assembly.
Q10What is your policy on strand-count discrepancy at receipt?
Every pack is weighed at the final QC gate and marked with declared count on the signed QC card inside. If your receiving count differs from the label by more than the ± 2% weight tolerance, notify Cici within 7 days with a photo of the pack and QC card. We reship or credit the difference at cost.
Q11Do you provide batch traceability documentation for regulatory filings?
Yes. Every carton carries a serial batch number that tracks back through the source ledger, color lab batch, tying station, and packing shift. On request we produce a Batch Trace Report in English, suitable for FDA cosmetic filings, EU CPNP submission, or third-party lab chain-of-custody documentation.
Q12Can I request retained batch samples for my own QC records?
Yes. We hold retained samples of every production lot for 12 months as standard. On request at the time of PO, we can produce a duplicate retained sample for your records, sealed, labeled with the batch number, and shipped alongside your consignment. No additional fee below 5 samples per PO.
Q2What is the difference between U tip and K tip?
K tip has a stick-shaped bond that fuses beside natural hair. U tip wraps around natural hair like a U before fusion. U tip has more bond surface area — better for thick or coarse hair. K tip has three shape variants (flat, round, stick) for finish options.
Q3How long does U tip installation last?
One install cycle lasts 10 to 12 weeks. Hair itself lasts 8 to 14 months with proper care. Reinstall same hair for 2-3 cycles with fresh keratin bond.
Q4Is U tip good for fine hair?
The Nano U Tip variant is designed for fine hair — 3mm U bond, 0.7g per strand. Standard U tip is best for average-to-thick hair. For very damaged or heat-sensitive hair, consider I tip cold fusion instead.
Q5What is the MOQ for wholesale U tip?
MOQ is 50 packs per SKU on stock colors and lengths. Custom colors or private label sets require 100 packs minimum. Mix U tip variants with K tip and I tip within one order to reach MOQ.
Q6How is U tip installed?
Section hair, wrap U bond around a section of natural hair, activate with fusion iron at 140°C for 2-3 seconds, roll the melted bond into a secure wrap, let cool. Full head install takes 120-150 minutes.
Q7Do you offer private label U tip?
Yes. Private label covers packaging box, hang tag, printed label, custom color ring, U-bond width, and length range. MOQ 100 packs per SKU on private label.
Q8What payment terms apply to orders?
Bank transfer, Alibaba Trade Assurance, PayPal, and Western Union. Custom and private label orders require 100 percent payment upfront. Stock orders also require full payment before production or shipment. No partial deposits.
