Some patients are put off having a FUE (follicular unit transplant) hair transplant procedure because they are worried that they will have to fully shave the back and sides of their head in order for our consultant surgeon Dr Asim Shahmalak to harvest the donor grafts. This is not the case.
In many cases, we shave only a very small section of the back or side of the scalp to obtain the donor hair. The shaved section is either in a square shape or, more likely, in small strip across the back of the scalp. An upper layer of hair is lifted and then we shave underneath, allowing the hair above to fall over the shaved area - covering it up. The shaved area is only really detectable to those who know you have had a transplant, and obviously the hair in the shaved area grows back quickly.
If you look at the pictures below, you can see the small section of Jack's shaved head shortly before the donor grafts were harvested.
The shaved section was a relatively thin strip with longer hair above it ready to fall down over once the grafts had been extracted.
We carried long-haired FUE on Jack so that he could maintain complete continuity in filming Corrie.
Jack came in for his hair transplant on the day the team at Corrie broke up for their two-week Christmas holiday.
If we had shaved the back and sides of Jack's head to get the donor hair, viewers might have been surprised by the change in his appearance when he returned to filming in January with his hair shaved.
The subtle way that the procedure was carried out meant that Jack could return to filming without any problems.
It will take up to a year for Jack's transplanted hair to fully grow back, so it shouldn't be too confusing for viewers.
The new hair will start to grow back very gradually from around three months after the operation - so any time from next month onwards.
But the change in his appearance will only be evident after a year when you look at his hairline when he was operated on and compare it to how he looks with the new hair fully grown back.
We will share those pictures with you when they are ready around Christmas time. Jack should get a brilliant result.
Jack is one of a number of celebrity hair transplant clients who have had FUE procedures with Dr Shahmalak including model Calum Best, former international footballer Didi Hamann, Homes Under The Hammer presenter Martin Roberts and Gogglebox star Chris Butland-Steed.
The TV doctor Christian Jessen has had two FUT (follicular unit transplantation) procedures with Dr Shahmalak - this is the more traditional method where a strip of skin is surgically removed from the back or side of the scalp to obtain the donor hair.
