How to choose Length
In general, straight hair is longer than curly hair, because it is completely straight (true to length) when we measured.
If you choose wavy/curly hair extensions, it is ideal to choose one longer size, Because Wavy/Curly always looks shorter than straight hair at same length. curly hair extensions tend to look most short than straight hair when you wear them. the normal finished length: straght hair >body wave>deep curly
Straight Virgin hair, true to its length, so buy the size as you wanted. Wavy hair is usually 1.5" shorter (unstraightened), Curly hair is usually 3.0" shorter than Straight hair.
We often suggest customers to purchase hair 2" longer if they desire a Curly hair look.If your natural hair is very short, you'd better choose the length under 18 inch, or you would feel uncomfortable. and if you have medium to long hair, it is ideal to wear long hair extensions.
