The Flip-In hair extension is one of the hottest and newly designed extension sets. The Flip-In is held together by an invisible band that fits your head like a crown. Once on your head this band magically disappears as it is blended into the rest of your hair. The Flip-In also includes clips on both sides for added security. In order to maintain your extensions use a wide tooth comb or brush rather than a fine tooth comb. Use detangler spray to help make the tangles and snarls come apart more easily. When using the hot curling irons, set the heat to its lowest setting. Avoid anything hotter than 140 degress as it could damage the extension. Approximately 18 inches in length.
