Product Construction Detail 01
Smooth, Low-Profile Top
The flexible PU base creates a flatter and cleaner top profile than an exposed traditional stitched-weft edge, supporting a more discreet appearance when correctly positioned.
Customizable Multi-Piece Set
Piece count, individual widths, hair allocation, and clip quantities can be configured to provide wider back pieces and narrower side pieces within one coordinated set.
Secure Pressure-Sensitive Clips
Clip material, size, color, spring tension, tooth shape, silicone lining, spacing, and attachment strength can be selected according to the approved product requirements.
Temporary Self-Application
The individual pieces can be clipped into the natural hair, removed after use, and repositioned without adhesive, tape, heat, beads, or sewing into the natural hair.

Product Overview
Product Construction & Key Details
PU clip-in hair extensions combine human hair, flexible polyurethane bases and snap clips in reusable sets. Also known as seamless clip-in hair extensions, they offer a smooth base finish for temporary length and volume. Epoche Hair manufactures this option for hair brands, wholesalers and distributors.
Flexible Polyurethane Bases
The PU base holds the hair along the top of each piece and supports the clip attachment areas. Its smooth surface gives this construction its seamless appearance. However, the finished look also depends on base dimensions, placement and natural hair coverage.
We customize the base specifications around your collection requirements. During sample review, assess the thickness, flexibility and edge finish together. Also examine how the hair meets the base on both sides of each piece.
Piece Widths and Clip Positions
A multi-piece set combines wider sections for the back with narrower pieces for the sides. Buyers choose the piece count and individual widths. We then arrange the clips to suit each piece and its intended position.
Clip options include different sizes, colors, materials, spring tensions and silicone linings. Review the opening action and attachment strength during sample testing. This helps you evaluate how the complete piece handles during application and removal.
Custom PU Clip-In Hair Extensions
Choose Virgin Hair or Remy Hair as the starting point for your range. Next, specify the length, texture, total set weight and long-hair ratio. We coordinate the hair allocation across the pieces to match your target fullness.
Consider the set weight alongside the piece configuration. Two sets with the same total weight can distribute hair differently. Therefore, review the complete sample set before confirming your production specifications.

Temporary Wear and Reuse
Users section their natural hair, place each piece and close the snap clips. The clips secure the set without tape, adhesive, heat or beads. For removal, open each clip before lifting the piece away from the natural hair.
Between uses, detangle gently from the ends upward while supporting the base. Keep the clips clean and let each piece dry fully before storage. Avoid pulling on the hair where it joins the PU base.
For your care guidance, confirm suitable washing products and styling temperatures through sample testing. Hair quality, color and styling habits all influence the care routine.
Colors and Construction Choices
Develop your collection with solid shades, blends or rooted colors. Our hair extension color ring provides a starting reference. You can also supply a physical sample for custom color development.
Review the finished hair color alongside the base and clip colors. Together, these details shape the overall appearance of each piece.
To compare alternatives, visit the Clip-In Hair Extensions collection. It includes Classic, PU and Invisible options. Epoche’s Invisible version uses individually inserted hair, so compare its injected surface with the PU sample when choosing your construction.
Private-Label Orders and Sample Approval
We develop PU clip-in hair extensions with custom labels and private-label packaging. Share your target hair quality, color range, piece layout and base requirements. Include any specific clip or packaging preferences in your brief.
Next, assess the samples for hair retention, base flexibility, color matching and clip performance. We confirm the agreed specifications with you before bulk production. Contact Epoche Hair to discuss your sample requirements.

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.
Remove all PU Clip-In pieces before sleeping, showering, swimming, or exercising.
Close the clips before brushing, washing, drying, or storing the extensions.
Brush each piece gently while supporting the PU base and clip area with one hand.
Begin brushing from the ends and work upward in sections without pulling on the PU base, hair attachment area, or clips.
View Complete Care Guide
Wash only when necessary using lukewarm water and a gentle, extension-safe shampoo.
Wash the pieces separately or in small groups while keeping the hair directed downward.
Apply conditioner and masks mainly through the mid-lengths and ends, keeping heavy products away from the PU bases and clips.
Do not leave the PU bases or metal clips soaking in water for an extended period.
Do not twist, sharply fold, stretch, or wring the PU bases during washing or drying.
Rinse thoroughly, press out excess water gently, and allow the pieces to dry completely before storage.
Use heat protection on the hair lengths and keep heated styling tools away from the PU bases, hair attachment areas, and clips.
Avoid alcohol-based products, strong solvents, or harsh cleaning agents on the PU material.
Inspect the PU surfaces, edges, hair attachment, clips, and clip fastening points before each application.
Do not use pieces with cracked, torn, stretched, or separating PU; loose hair attachment; damaged clips; or weak spring tension.
Store the pieces clean, dry, detangled, and arranged flat or on a suitable extension hanger.
Have damaged clips or unstable attachment areas repaired or replaced before continued use.

Frequently Asked Questions
Questions About This Product
What are PU Clip-In Hair Extensions?
PU Clip-In Hair Extensions, also known as Seamless Clip-In Hair Extensions or PU Seamless Clip-In Hair Extensions, are reusable temporary extensions made with flexible polyurethane bases fitted with pressure-sensitive snap clips. The PU construction creates a smoother and lower-profile top than a traditional exposed stitched-weft edge.
How are PU Clip-In Hair Extensions applied?
Section the natural hair according to the selected piece arrangement, position each PU piece close to the roots, and close the pressure-sensitive clips securely. Wider pieces are commonly placed across the back and narrower pieces around the sides. No adhesive, tape, heat, beads, or sewing into the natural hair is required.
What is the difference between PU and Classic Clip-In Hair Extensions?
PU Clip-Ins use a flexible polyurethane base that creates a smoother, lower-profile top. Classic Clip-Ins use a traditional stitched weft with clips attached along the sewn seam. The two products differ in top construction, thickness, flexibility, appearance, manufacturing process, and target price positioning.
Are PU Clip-In and Seamless Clip-In Hair Extensions the same product?
Yes. Within Epoche’s product naming, PU Clip-In Hair Extensions, Seamless Clip-In Hair Extensions, and PU Seamless Clip-In Hair Extensions refer to the same flexible polyurethane-base construction. Invisible Clip-In Hair Extensions are a separate product with a different hair-insertion and attachment-area structure, so the two products should be evaluated independently for base profile, thickness, flexibility, appearance, and price positioning.
Can PU Clip-In Hair Extensions be reused?
Yes. PU Clip-In Hair Extensions are designed for repeated temporary application while the hair, PU bases, hair attachment areas, and clips remain in suitable condition. Actual service life depends on hair quality, wear frequency, washing, heat styling, product use, storage, and the condition of the PU material and clips.
Can PU Clip-In specifications and samples be customized?
Yes. Virgin Hair or Remy Hair, length, texture, color, long-hair ratio, piece count, PU dimensions, PU color and transparency, hair-attachment construction, piece widths, hair distribution, total set weight, clip material, clip color, silicone lining, labels, and packaging can be customized. Samples can be evaluated before bulk production for PU flexibility, edge stability, hair retention, clip security, weight distribution, color, and finished workmanship.
