I have also been watching Big Brother which started out as interest in Calums hair I got drawn in by the vile people on display as to what they will do for publicity and fame.
As for Calums hair I have mixed feelings. As this is a result of 3 transplants assuming the frontal third perhaps half of his scalp I am not that impressed with the density into the hairline. That said it seems to be weaker in the central area where he had a forelock of hair. Perhaps the surgeon didn't transplant into this area and he is loosing more ground.
Without numbers and information it is very difficult to judge. He is achieving a good look in the rest of his scalp as he wears his hair very long and brushes back which covers more of the scalp. The problem with this hairstyle is wind and it will be blown out of place very easily and expose thinning areas, hence the product to hold in better in place.
I get the feeling that Calum is still not happy with his hair, he wears hats a lot of the time in the house which it seems he has been unable to ditch.
A hat can be a guys best support when concerned about hair loss but you can get trapped with wearing them all the time and it seems Calum has not yet ditched the cap. I may be wrong and he might love wearing them but it seems odd to wear a cap indoors if you still didn't have hair anxieties. I know he has cameras at every angle and people are looking at him and his hair but if he were content I don't feel he would still be wearing a hat so often.
I found this photo which shows his pattern of loss currently and the results of 2 or 3 procedures. Great beard donor if he wants to go down that route.
This is a latest photo taken from in the house which shows the density into the front.
I do think the the work looks very natural and his low hair to scalp contrast will help with that and that his donor area looks to be very good. I wonder if he will go for a 4th procedure.
