Unfortunately not all clinics operate to the very high standards of Crown Clinic.
This is especially true of clinics abroad, particularly those in countries like Turkey where regulation of the hair transplantation industry in minimal.
Hair transplantation in the UK is very tightly regulated. No one can operate without going through exhaustive but necessary tests and inspections each year.
Sadly that is not the case in other countries.
One patient who came to Crown Clinic seeking repair work was lovely Adeleh Deane, 39, who was left with an ugly 'Frankenstein-style' scar on her head after a botched cut-price transplant operation in Thailand.
Adeleh paid just £1,500 for the surgery in Bangkok - a quarter of the price for the same procedure in UK hospitals.
But the bungled operation by a 'butcher' left Ms Deane with a severe scar along her hairline, thinning patches of hair and a paler strip of skin where surgeons had stitched flesh across her scalp.
She was forced to seek reconstructive surgery from Dr Shahmalak to fix the damage caused by doctors at the unregulated Thai clinic.
Dr Shahmalak carried out a seven-hour grafting operation on Ms Dean to individually move more than 3,000 follicles onto her forehead and fix the damage.
The surgeon, whose celebrity patients include model Calum Best, TV doctor Christian Jessen, football pundit Didi Hamann, Homes Under The Hammer presenter Martin Roberts and Chris Steed from Gogglebox, said around 10% of all his ops are fixing surgery carried out overseas.
Dr Shahmalak said: "It was a difficult procedure because we were repairing damage caused by an earlier botched operation. It's never easy transplanting onto a scar but in this case the results were very good and I was pleased."
Ms Deane said: "I couldn't afford to go to a proper surgeon - so I went to a butcher, basically. I had a Frankenstein scar and now you can't see it."
