The majority of wigs are made from Asian hair. Chinese hair has a thicker denier (unit of fineness) which results in the hair being extremely straight. It is a bit more resistant to curl and can therefore be harder to style. Indonesian hair is found in greater supply and is less costly -- it can often be found in ethnic style wigs. Indian hair has thinner denier close to that of European hair but with a bit more texture.
European hair is the most sought after for its fine denier but due to its increasingly limited supply in the marketplace, it is more expensive. Human hair wigs do not come pre-styled and may need a trim or thinning to get the style and texture desired. This allows you to have your hairstyle personalised allows the option of changing your hairstyle without changing your wig as heat appliances can be used; curling irons, straightening irons, blow dryers and other heat sources.
