Hair transplants can now look natural, provided the patient is with a good cosmetic surgeon.
This is the view of Marilyn Sherlock, chairwoman of the Institute of Trichologists.
Ms Sherlock said that hair transplant surgery is "superb" and is much improved from 30 years ago when "it failed a lot".
The expert explained the new method involved in fitting hair transplants.
"They take a thin strip of scalp from along the back of the head and, having removed this thin strip, they stitch the scalp together again," she said.
"They take out this strip with all the hairs in it and then the hairs are dissected from this and put in at the top of the head."
Earlier this year it was revealed that actor James Nesbitt underwent hair transplant surgery.
He explained that he has been "very pleased with the results", noting that it wasn't a decision he made lightly.
