DISCLAIMER: If you have thin, brittle, damaged or delicate hair, please note that the fairy hair may fall out at a much faster rate whereas strong, thick hair may retain hair longer. Some may find their fairy hair lasts several weeks or months. For younger children, it may only last a week or two. There is no guarantee for fairy hair lasting any particular length of time as it is subject to the fineness/thickness & weakness/strength of each hair follicle it is tied into. The tinsel strands will fall out when hair follicles shed naturally, so you may see loss of strands on a daily or biweekly basis.
