Harrowing footage of a dead teenager having his hair cut was posted on Facebook without his parents' permission.
Cameron Chadwick, 15, died on February 7 after his moped hit a lamp post in Wigan, Manchester.
Police said the 15-year-old died in hospital.
Grief-stricken Stacy and John Chadwick had asked staff from Mo's Barbers to trim his hair.
But as a hairdresser from the shop cut Cameron's hair, his friend filmed it and posted it on Facebook.
One outraged friend responded to the video: "I cannot believe my friend trusted you to cut her precious son's hair before she laid him to rest and you took a video ... disgusting."
The shop later apologised and said: "I hope everyone forgives us, especially Cameron's family."
After Cameron's death, his family described the teenager as a "beautiful brave boy, taken from us all too suddenly".
They added: "Life itself will never be the same. The happiest, funniest, loving lad. We love you Cameron, always and forever in our hearts."
A statement from Cameron's head teacher, Paul Bousfield of Abraham Guest Academy, said the "popular and lively" student would be "sadly missed by all".
