Product Construction Detail 01
No Conventional Folded Return Hair
The PU construction secures the hair within the top base rather than folding short return hair over a traditional stitched edge, creating a cleaner top profile.
Customizable PU Specifications
PU material, width, thickness, flexibility, color, surface finish, edge profile, and hair distribution can be developed according to the approved sample.
Cuttable Continuous Weft
When the approved PU construction allows cutting, the continuous weft can be divided into shorter sections. Fresh edges should be inspected and finished according to the confirmed specification.
Controlled Hair Distribution and Weight
Hair weight, total weft length, strand alignment, PU coverage, and distribution are coordinated to support repeatable bundle specifications and sample-to-bulk consistency.
OEM and Private Label Development
Hair quality, lengths, textures, colors, long-hair ratios, bundle weights, PU specifications, labels, and packaging can be customized through sample confirmation.

Product Overview
Product Construction & Key Details
PU Weft Hair Extensions use a thin polyurethane base to hold and align human hair along the top edge. This construction creates a flatter profile than a conventional Machine Weft. It also avoids the traditional folded return hair found on many stitched wefts.
The PU strip forms the main structure of the weft. Buyers can specify its width, thickness, flexibility, color, surface finish, and edge profile. Epoche also controls hair alignment, distribution, and coverage according to the approved sample. These details influence the finished profile, handling, and consistency of the product.
Flat PU Weft Construction
The market may also describe this product as a Flat PU Weft, PU Hair Weft, or Polyurethane Weft Hair Extension. Some suppliers also use the term PU Skin Weft. Terminology varies between manufacturers, so buyers should compare the actual construction instead of relying only on a product name.
A PU Hair Weft secures the hair inside the polyurethane top base rather than a raised machine-sewn seam. This structure keeps the top area smooth and relatively flat. Buyers should evaluate PU thickness, flexibility, hair quantity, base width, and hair distribution together when approving a sample.
Professional Double-Sided Tape Installation
Professionals install PU Weft Hair Extensions with double-sided extension tape. The adhesive connects the polyurethane base with prepared sections of natural hair. The stylist selects the tape type, section size, spacing, and placement for the chosen application.
Clean preparation helps the adhesive perform consistently. The natural hair and PU surface should remain free from excess oil, conditioner, and styling residue before installation. During maintenance, the stylist should inspect the attachment area and PU base for lifting, separation, or damage.

Cutting and Edge Control
Professionals can divide a continuous PU Weft into shorter sections when the approved construction allows it. Cutting should stay within the designated polyurethane area. After cutting, the stylist should inspect each edge and confirm that the PU layers remain stable. The approved product specification determines whether the cut edge needs additional sealing.
PU Weft vs Machine Weft Hair Extensions
PU Weft and Machine Weft Hair Extensions use different top constructions. Machine Weft uses rows of machine stitching and normally includes return hair. PU Weft uses a thin polyurethane base and a flatter top profile.
The attachment methods also differ. Professionals usually sew a Machine Weft into a prepared installation system. PU Weft uses professional double-sided adhesive tape. Buyers should therefore compare profile, flexibility, hair distribution, attachment method, maintenance, and cutting requirements separately.

Care & Longevity
Preserve Quality, Structure and Appearance
Practical maintenance guidance helps preserve hair quality, protect the attachment area, maintain appearance and support longer service life.
Have PU Weft Hair Extensions installed, maintained, repositioned, and removed by a trained hair extension professional.
Brush gently with a suitable hair extension brush while supporting the hair above the PU and adhesive attachment areas.
Begin at the ends and work upward in sections. Avoid pulling directly on the PU base or taped attachment points.
Wash with lukewarm water and a gentle shampoo formulated for human hair extensions. Keep the hair directed downward while washing.
View Complete Care Guide
Keep conditioner, oils, masks, serums, and heavy styling products away from the PU base and double-sided adhesive attachment areas.
Rinse thoroughly to reduce product buildup around the PU and tape connections.
Do not sleep with wet or damp hair. Dry the roots, PU bases, and surrounding attachment areas completely after washing.
Secure long hair loosely before sleeping to reduce tangling and pulling around the installed wefts.
Use heat protection on the hair lengths. Keep heated styling tools away from the PU base and adhesive attachment areas.
Avoid pulling, twisting, sharply folding, scratching, or brushing aggressively around the PU base.
Have lifted tape, loose sections, uneven tension, or excessive natural-hair growth checked by a trained professional.
Inspect the PU surface, hair embedding, cut edges, and adhesive contact area during maintenance.
Follow the approved adhesive-system instructions when removing or replacing double-sided tape.
After removal, clean, dry, detangle, and organize reusable PU Weft sections before professional storage or reinstallation.

Frequently Asked Questions
Questions About This Product
What are PU Weft Hair Extensions?
PU Weft Hair Extensions are continuous human hair wefts with aligned hair secured within a thin polyurethane base. Also referred to in some markets as PU Skin Wefts, they provide a flatter and more flexible top profile than a conventional raised machine-stitched seam.
Do PU Weft Hair Extensions have return hair?
The PU Weft construction described on this page is made without conventional folded return hair. The hair is embedded directly into the polyurethane base, creating a clean top edge with a different structure from Machine Weft and Hand-Tied Weft products.
Can PU Weft Hair Extensions be cut?
Yes. A continuous PU Weft can be divided into shorter sections by cutting through the polyurethane base at the required placement point. Each cut edge should be inspected to confirm that the hair remains securely embedded and that the PU layers have not separated. Additional edge securing may be used when required by the approved specification.
What is the difference between PU Weft and Hand-Tied Weft Hair Extensions?
PU Wefts use a thin polyurethane base and are made without conventional folded return hair. Machine Wefts use reinforced machine stitching and include return hair. Traditional Hand-Tied Wefts use hand-knotted thread seams, are supplied as pre-sized pieces, and should not be cut through the seam. Thickness, flexibility, weight capacity, and cutting requirements depend on each confirmed specification.
How are PU Weft Hair Extensions installed?
PU Weft Hair Extensions are professionally installed with double-sided adhesive tape. The tape secures the polyurethane base to selected sections of natural hair. Tape type, section size, placement, pressure, maintenance, and removal should follow the approved product and adhesive specifications.
Can PU Weft specifications and samples be customized?
Yes. Virgin Hair or Remy Hair, length, texture, color, long-hair ratio, bundle weight, total weft length, PU formulation, base dimensions, flexibility, hair embedding, cut-edge stability, labels, and packaging can be customized. Samples can be evaluated before bulk production for PU curing, cutting performance, hair retention, flexibility, color, and finished workmanship.
