This has been been a real trend within my homeschool groups the last couple of years- girls ( and one boy!) growing their hair long in order to donate it . Locks of Love is a non-profit group that gives hair ( made into wigs) for children who have lost their hair because of medical reasons or medical condition.
Here are their Guidelines for Donating Hair:
Hair that is colored or permed is acceptable.
Hair cut years ago is usable if it has been stored in a ponytail or braid.
Hair that has been bleached (usually this refers to highlighted hair) is not usable. If unsure, ask your stylist.
Hair that is swept off of the floor is not usable.
Hair that is shaved off and not in a ponytail or braid is not usable.
We cannot accept dreadlocks. Our manufacturer is not able to use them in our children’s hairpieces. We also cannot accept wigs, falls, hair extensions or synthetic hair.
Layered hair is acceptable if the longest layer is 10 inches.
Layered hair may be divided into multiple ponytails.
Curly hair may be pulled straight to measure the minimum 10 inches.
10 inches measured tip to tip is the minimum length needed for a hairpiece.
Please Note: Shorter hair will be separated from the ponytails and sold to offset the manufacturing costs. Although the shorter hair cannot be used in the hairpieces, it still greatly helps to reduce costs.
Gray hair will be accepted and sold to offset the manufacturing costs.
