Buying human hair—whether for personal use or business—is an investment. The global market is filled with a wide range of hair extensions and wigs, but not all of them are created equal. You might see labels like “100% human hair,” “virgin,” “Remy,” or “raw hair,” but these terms can be misleading if you don’t know how to verify the quality yourself.

Whether you’re starting your hair brand or simply want the best hair for personal use, testing hair quality before making a bulk or retail purchase is crucial. In this guide, we’ll walk you through practical steps and tests to ensure the hair you’re buying lives up to its promises.

1. Ask for Samples First

Before diving into lab-style tests, the first and most important rule is: never purchase large quantities without ordering samples first.

Ask your supplier:

• Can I test a bundle or a closure first?

• Do you provide sample kits?

• Are samples from the same batch as bulk orders?

Reputable suppliers like OrientalHairs.com are confident in their quality and will gladly send sample products for testing.

2. Visual Inspection: First Impressions Matter

Upon receiving the hair, your first task is a visual and tactile check:

✅ Look for:

• Natural luster or shine (not overly glossy like silicone-coated synthetic hair)

• Uniformity in color and texture

• Clean wefts, no visible glue or strong odors

• Aligned cuticles (especially for Remy hair)

🚫 Avoid if:

• The hair looks overly processed or plastic-like

• It has a strong chemical or burnt smell.

• It feels unnaturally slick or sticky.

• There are many short strands mixed in

If the hair doesn’t pass this basic test, don’t proceed with further testing—it’s likely low quality.

3. The Burn Test: Real vs. Synthetic

One of the oldest and simplest methods to determine if the hair is 100% human or synthetic is the burn test.

🔥 How to do it:

1. Take a few strands from the bundle.

2. Burn them with a lighter.

3. Observe the smell and ash.

Results:

• Human hair will burn slowly, smell like burnt protein (similar to burnt feathers), and leave soft, gray ash.

• Synthetic hair will melt or burn quickly, emit a plastic odor, and form a hard bead or ball.

⚠️ Note: Always do this safely and only with a few strands.

4. The Tangle & Shedding Test

This test helps identify how the hair behaves under stress. Good quality Remy or virgin hair should resist tangling and minimal shedding.

How to do it:

• Run your fingers or a wide-tooth comb through the hair from weft to tip.

• Do this repeatedly, and check how many strands fall out.

• Also, shake the bundle or brush it to see how much hair tangles.

What to look for:

• Minimal shedding: A few strands are normal, but excessive hair fall is a red flag.

• No tangling: If the hair tangles with gentle brushing, it’s likely mixed, low-grade, or improperly processed.

5. The Water Test

This test reveals true texture and processing levels. Many suppliers use steam or chemicals to create curls or waves that disappear after washing.

How to do it:

• Wet the hair thoroughly with warm water.

• Use a mild, sulfate-free shampoo and rinse.

• Let the hair air-dry.

Results:

• Raw or virgin hair should return to its natural wave or curl pattern.

• If curls disappear entirely, the hair may be synthetic or heavily processed.

• Also, observe for dye bleeding or unusual odors.

6. Cuticle Alignment Test

For Remy and raw hair, cuticle alignment is key. All hair strands should lie in the same direction to prevent tangling and matting.

How to test:

• Hold the hair bundle and run your fingers downward—smooth movement is expected.

• Now, run your fingers upward (from tip to weft).

• You should feel resistance, but not a rough, snaggy texture.

If the hair feels harsh in the opposite direction or tangles instantly, the cuticles are misaligned, indicating non-Remy or mixed hair.

7. Heat Styling Test

To confirm whether the hair can tolerate regular styling tools like flat irons or curling wands:

How to do it:

• Take a section of the sample and apply a heat tool at medium-high heat.

• Observe how the hair responds.

Good indicators:

• The hair straightens, curls, or styles easily without burning.

• There is no smoke or melting.

• Hair remains soft after styling.

Synthetic or poor-quality hair may burn, melt, or become stiff.

8. Dye Test (Optional)

High-quality virgin or raw hair can usually be dyed or bleached. This test is best for those who plan to custom color hair for their clients or product line.

Warning:

Only attempt this test on virgin or raw hair, not Remy or colored hair.

How to do it:

• Apply a small amount of developer + bleach or permanent dye to a few strands.

• Wait 10–15 minutes and observe the lift.

Results:

• True virgin hair will lift in color.

• Chemically treated or synthetic blends will show little change or become damaged.

9. Confirm Ethical Sourcing and Transparency

A supplier’s willingness to share sourcing and production details says a lot about their reliability.

Ask them:

• Where is the hair sourced from (Vietnam, India, China, etc.)?

• Is the hair from a single donor or mixed?

• Are any chemicals used in the processing?

• Can I see your factory or team?

Companies like OrientalHairs.com take pride in ethical sourcing and offer transparency throughout the supply chain.

10. Compare Price vs. Value

Don’t let price be your only guide. Cheap hair is often non-Remy, synthetic blends, or over-processed. Instead, focus on value—longevity, styling versatility, and customer satisfaction.

Think long-term:

• Would your customers repurchase?

• Will it hold up for 6 months or more?

• Will it build trust in your brand?

Paying a bit more upfront for tested, high-quality hair will always pay off in the long run.
