The hairstyles of women and men alike have been effected for hundreds of years by the addition of hair to a persons existing hair for an increase in length or fullness. Hair extensions have been since their inception a fantastic way to manipulate the appearance and fashion of hair. Hair designers professionally add the synthetic or real human hair onto persons scalp in a variety of ways that have evolved of the centuries. Colors and purposes for the extensions added depend on the person who is getting them done; new looks are traditionally created to dramatize the existing appearance of the hair while keeping a natural feel.
Thick or curly, long or short, extensions exist to be added to any hair length or texture type. If a person desires their straight hair to be longer, then they would get the closest available texture which mimics their own to add length. Keeping the texture the same will simulate that extensions are the same as natural hair growing from the scalp. To add fullness to a curly limp hair a similar curl or wave would be selected in an extension and added in the most natural manner possible. In some cases hair color will be different for an extension than the color of the naturally grown hair of a person, this can be for adding subtle dimension in a dull existing look or bold colors can be added to create a focus/iconic look.
The difference in natural or synthetic origins will change what colors or uses the new hair has. Some natural extension brands may only come in the natural human hair they were grown in, while others have pre-dyed colors in their lines. Traditionally the more bold and vibrant/electric colors come from makers of synthetic hair; the synthetic hair is often very sensitive to heat and should be carefully maintained in order to keep it in a desirable texture and favorable color. Natural hair that has come from a human can be maintained and heated same as most human hair. A synthetic extension that cannot be heated is usually produced in the style that it is intended to be worn for the duration of its use.
Men have been known to use hair extensions same as women, there is no discrimination in this way. A man may add extensions to avoid changing the overall appearance of his hair color in a bold way instead in a subtle way without using any haircolor on his natural hair. Women who desire length beyond their own natural capacity to grow can have it in a day instead of waiting years to painfully grow it on their own. Even children who are sick can benefit from the help of extensions, there truly are very few limits to the possibilities.
