Shift manager Jim Innes and James Hanson, who works in maintenance and facilities at I Force in Bangrave Road, Corby, teamed up for the fundraiser in support of Lakelands Hospice.
James braved the shave, saying goodbye to his beard of 20 years.
And Jim let his work colleagues colour his hair and beard every day for a week, including one day with the colours of the rainbow.

It is entirely funded by voluntary donations and support from the community.
And Marina added: “If Jim and James have inspired you, why not do something creative, wacky or zany in June and rise to our #challenge and raise vital funds for Lakelands Hospice?”
