Donating hair is straightforward: grow it to at least 8 to 14 inches (depending on the organization), cut it in a clean ponytail or braid, and mail it to a nonprofit that makes wigs for people with medical hair loss. The whole process from cut to mailbox takes about 15 minutes, but a few details matter if you want your donation to actually be usable.
How Long Your Hair Needs to Be
Minimum length requirements vary by organization. Children With Hair Loss accepts donations starting at 8 inches, making it one of the most accessible options. Wigs for Kids requires a minimum of 12 inches, though they strongly prefer 14 inches or more. In Australia, the Alopecia Areata Foundation asks for at least 36 centimeters (about 14 inches).
These minimums exist because shorter hair can’t be used during wig manufacturing. Hair loses some usable length during the process, so longer donations are always more valuable. If you’re on the fence about when to cut, growing an extra inch or two beyond the minimum gives wig makers more to work with.
To measure accurately, pull a section of hair straight (not stretched) and measure from where you’d place the elastic band to the ends. Curly hair should be measured while straight, since the curl will shorten the usable length significantly.
What Type of Hair Is Accepted
Most organizations accept hair that has been colored or highlighted, but permanent dye, semi-permanent dye, and bleach are typically disqualifying. The chemicals weaken the hair shaft enough that it won’t hold up during wig construction or wear. If you’ve only used temporary rinses or henna, check with the specific organization, as policies differ.
Gray hair is accepted by most charities. Permed or chemically relaxed hair is generally not. Hair that has been flat-ironed or heat-styled is fine as long as it hasn’t been chemically treated. The key factor is the structural integrity of the strand, not its color or texture.
Hair should be clean and completely dry before cutting. Damp hair can develop mold during shipping, which ruins the entire donation.
How to Cut and Prepare Your Hair
You can do this at a salon or at home with a friend’s help. Here’s the process:
- Section your hair into ponytails. Most people end up with four to six ponytails depending on hair thickness. Smaller sections are easier to cut cleanly than one massive ponytail.
- Secure each section with an elastic band placed about one to two centimeters below where you plan to cut. Then braid each ponytail and tie off the end as well. This keeps the hair aligned and prevents it from tangling in the envelope.
- Measure before cutting. Pull each ponytail straight and confirm it meets the minimum length from the elastic to the tip. It’s much easier to fix this now than after the scissors come out.
- Cut one to two centimeters above the elastic. This gives you a clean edge while keeping the elastic securely on the donated portion.
One donor’s full head of hair, when sectioned properly, produces four to six ponytails. It takes roughly four or five complete donors to create a single wig, since ponytails vary in length, thickness, and texture. Your donation gets combined with others to build one finished hairpiece.
Where to Send Your Donation
Several U.S. nonprofits accept mailed hair donations. The biggest differences are minimum length, who receives the finished wigs, and whether recipients pay anything.
- Children With Hair Loss: 8-inch minimum. Provides free wigs to children and young adults with medical hair loss.
- Wigs for Kids: 12-inch minimum (14+ preferred). Provides free wigs to children under 18.
- Hair We Share: 12-inch minimum. Provides free wigs to children and adults with hair loss from any medical condition.
Organizations like the National Alopecia Areata Foundation maintain directories of groups that provide free wigs to children and young adults with conditions like alopecia areata. If you want your hair to reach a specific population, check each charity’s recipient criteria before mailing.
Outside the U.S., the Australia Alopecia Areata Foundation accepts donations of 36 centimeters or longer that are free from permanent or semi-permanent dye. They send donated hair to wig makers who specialize in medical hairpieces, and the proceeds fund their Grant A Wig for Kids program. In the UK, the Little Princess Trust operates a similar model with a 12-inch minimum.
Packaging and Mailing
Place each ponytail or braid in a sealed plastic bag to protect it during transit. Put the bag in a padded envelope or small box. Most organizations provide a printable donation form on their website to include with your hair, which tracks who sent it and ensures it gets processed.
A hair donation in an envelope typically weighs well under 13 ounces, so first-class mail at the post office counter works fine and costs a few dollars. If you’re shipping from home, services like Pirate Ship let you print discounted first-class labels for packages up to 16 ounces. Priority mail works too but costs more and isn’t necessary for something this light. One thing to note: padded or “bumpy” envelopes sometimes trigger a small surcharge at the counter, so a flat rigid mailer can save you a bit.
Most organizations don’t send confirmation receipts unless you request one, so check their website for tracking options. Some provide a donation acknowledgment you can use for tax purposes.
What Happens After You Donate
Your ponytails get sorted by length, color, and texture, then grouped with donations from other people. It takes 20 to 30 individual ponytails (from about four to five donors) to construct a single custom wig. The manufacturing process involves hand-ventilating each strand into a wig cap, which is why these hairpieces can cost thousands of dollars when purchased commercially. Donated hair makes it possible for families to receive them at no cost.
Recipients are typically children or young adults experiencing hair loss from conditions like alopecia, chemotherapy, burns, or other medical causes. For many of them, a well-fitted wig made from real human hair makes a meaningful difference in how they feel at school and in social situations. The timeline from donation to finished wig varies, but it often takes several months due to the sorting, matching, and handcrafting involved.
