Human hair wigs are softer and shinier as compared to synthetic ones. Further, it is easier to style these in many ways. The movement and texture are more natural and spontaneous. To keep these qualities intact, the processing technique used for human hair is more artful so that the strength and density of hair remains unaffected.
With technological advances, synthetic hair has come a long way in recent years. In some cases it is difficult to tell the difference — the denier and texture are such that they feel almost like human hair. As a matter of fact, with some of the higher quality synthetic pieces, you would never know they were not natural human hair wigs if you didn’t have the human hair right next to it to compare!
One tip to differentiate between synthetic and human hair wigs is the fact that the former tend to either get burnt or melted when it comes in contact with heat. Also, synthetic hair wigs have permanently set patterns when it comes to hair styles. These are more resistant to hair problems that accompany changes in weather, for e.g., frizziness during monsoons.
If you touch them, most probably you can make out that its synthetic. One more test is for you to use a heating iron to test the hair. The synthetic one will melt.In terms of life-span, synthetic hair wigs are less durable than human hair wig. A human hair wig will last for over a year, whereas synthetic hair wig will last 4-6 months.
