Supermarket staff will don bright orange wigs every Wednesday this month to raise money and funds for multiple sclerosis research.
Peter Kane, 34, a store manager at Asda in Mitcham and his 30 colleagues are taking part in ChallengeMS, an annual fundraising event run by the MS Society which aims to raise £125,000 for MS research during September.
Mr Kane signed up to the challenge because his mum lived with the condition for 10 years and passed away last year at the age of 50.
He said: "I spent a lot of time watching my mum struggle with MS over the years.
"It’s an unpredictable condition which can throw up challenges on a daily basis.
"I also saw how quickly someone can deteriorate through having MS.
"I think it's important to raise awareness as I don't think many people know about the disease and how it affects the individuals who are dealing with it."
The MS Society is a charity for the 100,000 people living with multiple sclerosis in the UK.
The charity said symptoms of MS usually start in your twenties or thirties.
The condition can get steadily worse, or remain unpredictable throughout your life – one day you can be fine, the next you might lose your sight or be unable to move, the charity said.
