Hi Kelly! Sounds like you are raising an amazing, compassionate young lady!
The Harmony Barber Shop just off of Main Street in the Magic Kingdom is one of the best kept secrets at Walt Disney World. My daughter had her first haircut there, and they made it such a special experience!
The Harmony Barber Shop does not work directly with Locks of Love, but the Barber Shop is happy to assist guests wishing to donate their hair. One of the barbers would cut your daughter's hair and then give it to you so that you could send it in to Locks of Love. The mailing address and other details can be found at www.locksoflove.org.
The Harmony Barber Shop is open daily from 9 a.m. to 6 p.m. Children's haircuts cost $15; special first haircuts, which include a commemorative Mickey ears hat, cost $18.
Hope you and your daughter have a magical visit!
