Stokes, 25, convinced his 23-year-old team-mate to look into the KSL Hair firm after he had advertised it on Twitter.
Former Hibs striker Griffiths said at the time: “I’ve been thinking about this for some time now and thought now is as good a time as ever to get it sorted.
“It’s only started to become more noticeable in the past two years, so I thought it was time to do something about it. I believe KSL Hair are the team to sort this issue once and for all for me. They understand what you’re going through.”
And KSL Hair tweeted a photo of the Celtic Park duo following the first stage of the process.
The Hoops’ forwards have also been joined by fellow striker James McFadden, who has undergone a similar operation but from a different clinic; The Glasgow Clinic.
After the Motherwell stikers operation, Director of The Glasgow Clinic, Fraser Christensen said: “We’re very happy that James came to us for his hair transplant.
“Hair loss isn’t easy for a lot of people to deal with, both male and female. It’s definitely becoming more talked about and less of an issue.”
The dad-of-four revealed to his Motherwell team-mates that he would be undergoing Follicular Unit Extraction (FUE) following the 1-0 win over Aberdeen, after getting stick from them over his lack of hair.
The three hitmen follow in the steps of England and Manchester United striker Wayne Rooney, who has also undergone FUE treatment.
