Anybody can donate, but each charity has specific length and texture requirements, in addition to various restrictions on hair that’s undergone heat, chemical, or color treatments.
You can ensure you’re picking the right charity by researching their policies and who the donation will benefit. It's also recommended to contact the charity with any questions.
For most charities, the minimum hair length is 8 inches because each strand is significantly shortened during the wig-making process. Therefore, extra-long hair is in demand.
Charities want hair that is of excellent quality, and many prefer hair without prior exposure to chemicals. Split ends must also be cut off before the hair is donated.
