How to Request an Accurate Density Test for a Human Hair Wig Sample

Before approving a wholesale order, ask the manufacturer to test a sample against the specifications you expect in production. A useful density assessment checks the wig's finished weight, hair length, strand distribution, and lace or cap construction. Providing these details in advance helps you judge whether the sample is representative of a larger batch.

What to Include in Your Sample Request

Specify the product and the measurements you want verified. For a bob wig, for example, note the requested length (such as 8–16 inches), 100% human hair, texture, color, cap type, and target density. Indicate whether you need a lace-front, closure, or full-wig construction, and ask for weight and length checks before shipment.

• Hair specifications: State the material, length, texture, color, and density target.
• Cap details: Identify the lace size and construction, including lace-front, closure, or full wig.
• Inspection requirements: Request verification of finished weight, root-to-tip length, strand placement, texture, and lace attachment.
• Production reference: Ask the supplier to use the same criteria for the sample and any later production batch.

How a Practical Density Check Works

Density is not determined by a single number. The amount and placement of hair across the cap, the finished unit's weight, and the wig's length all affect how full it looks and performs. A structured review should therefore cover the hair before assembly as well as the completed wig.

Ask the factory to document its checks for raw hair, color, length and weight, texture, wefts and lace, and final product condition. Comparing these results with your requested specifications can reveal whether the sample has the coverage, feel, and styling flexibility your customers expect. This is especially useful for salons, wig shops, online sellers, and private-label brands that need consistent products across repeat orders.

For customized orders, put density requirements in writing alongside the chosen cap and lace construction. Wholesale experience with wigs, bundles, and lace closures shows why agreeing on weight and attachment standards early can help maintain consistency across different lengths and natural color options.

Frequently Asked Questions

How can I check the density of a bob wig sample?

Review the finished wig's weight and length, then check how evenly the hair is distributed over the lace cap. These measurements together provide a more useful comparison with your requested specifications than appearance alone.

Which details should an OEM/ODM request include?

List the hair material, length, texture, color, lace dimensions, cap style, and target density. For example, you may request 100% human hair in an 8–16-inch straight or body-wave style, with a specified lace-front, closure, or full-wig construction.

How long do sample orders take?

Stock samples typically take about 7 days. Custom OEM/ODM samples generally require 15–30 days, depending on the style, color matching, and cap details.

Preparing to Scale Your Order

A representative sample gives you a chance to confirm density, weight, length, and construction before committing to volume. Start with clear written criteria, request the relevant inspection results, and make those standards part of the bulk order's quality-control process. Sample and wholesale shipments can be arranged through DHL, FedEx, UPS, air freight, or sea freight. Available payment methods include T/T bank transfer, Alibaba Trade Assurance, PayPal, and Western Union. For technical questions or sourcing support, contact sales@brazilianhairtop.com.
