How long does the hair have to be? This is always the first question we get. In order to create a realistic looking piece we need at least 10 inches of hair. We have been able to work with shorter lengths in special situations. The hair needs to be clean, dry and braided with an elastic on both ends. Many small braids are preferable to a few large ones.... check our site under donations or our facebook page under notes for a tutorial on donating hair.
