When it comes to testing the quality of raw hair, there are several key factors and methods to consider. Here's a guide on how to test raw hair quality:

1. Visual Inspection:Luster: High-quality raw hair should have a natural shine.
   Color: The color should be consistent and natural, without any odd discolorations.
   Ends: Check for split ends. Healthy hair should have minimal split ends.
   

2. Texture Test:Run your fingers through the hair to feel its texture. It should be smooth and soft, not rough or dry.
   

3. Tangle Test:Brush the hair to see if it tangles easily. Quality raw hair should be relatively tangle-free.
   

4. Shed Test:Run your fingers through the hair or comb it to see if it sheds. Minimal shedding is a sign of good quality.
   

5. Cuticle Alignment:The cuticles of high-quality raw hair should all face the same direction. This can be tested by running your fingers down the hair shaft; it should feel smooth. If it feels rough or uneven, the cuticles might not be aligned.
   

6. Water Test:Wet the hair to see if it retains its texture. Quality raw hair should return to its natural state after being wet.
   

7. Chemical Test:Apply a small amount of bleach to a strand of hair to see how it reacts. High-quality raw hair should lighten gradually without breaking down immediately.
   

8. Elasticity Test:Stretch a small section of the hair to see if it returns to its original length without breaking. Good quality hair should have some elasticity and bounce back.
   

9. Smell:Smell the hair for any chemical odors. Quality raw hair should have a natural scent without any chemical smells.
   

10. Burn Test:

• Take a small strand and burn it. Quality human hair should burn with white smoke and turn to ash. Synthetic hair, on the other hand, will burn with black smoke and form a sticky ball.

1. Longevity Test:

• Over time, high-quality raw hair should maintain its luster, softness, and integrity with proper care.

Testing raw hair quality thoroughly ensures that you are getting a product that will last and maintain its appearance over time.
