Michael has in the past revealed he was holding on his strands until he was ready to raise some funds for his chosen charity, Children's Hospital Randwick.
On his official charity page, the star promised: "If the target is reached, I have pledged to cut off my hair on live TV during Nine’s Gold Telethon in Sydney on Monday, June 10 from 9.00am."
