No single answer!

1) Virgin European hair feels cool to the touch, but knots cannot easily be bleached, and if it is permed to make it curly, the quality suffers greatly. But the worst thing is that it tangles when tied in with normal split or single knots, because the returns go in the opposite direction, so it's only useful for injected hairpieces, which have a lower density limit. Plus It is very expensive indeed so we do not even offer it!

2) Our Indian hair is widely regarded as the best hair. It does not tangle, and if you choose a darker color and less curly hair, it is simply unbeatable with it's beautiful feel and long life.

3) Remy hair is second best, after our normal Indian hair. The individual hair shaft diameter is unnaturally thick for most European or African clients and it shows. Ironically, most hairpiece sites promote Remy as superior and most clients believe it, but it is second best for straighter hair. However, it does do better than normal Indian if the perm is quite tight.

4) Kanekelon, our synthetic hair, has disadvantages and advantages. If you have dark hair and light density, we cannot bleach the knots so human wins. But because human hair quality suffers considerably when the color is light or the curl is tight, synthetic hair will give nicer results if you have very curly hair or a blond color. If you have a tighter curl and darker hair, you have to weight the advantages of nicer feeling, less frizzy synthetic against bleachable knots on partly perm-ruined human hair.

5) If you want it long and straight, then only Chinese human, or synthetic, will deliver perfectly straight hair. Indian and Remy hair have a natural 5cm wave that in very long hair, makes it look curly!
