In the first picture, Silva was 18 years old and his hairline looked fairly healthy. We can place him at Norwood 1, which Norwood himself describes as ‘minimal or no recession of the hairline’ [2].
In the second picture, it looks as if there is a slight recession at the temples, however, without knowing if he had hair loss, this could be viewed as a mature hairline.
It is normal for men around this age to experience changes in their hairline, as this is what happens as the hairline naturally matures and moves back with age. However, it is likely that David Silva has a genetic predisposition to balding as he showed common signs of male pattern baldness earlier in life, such as hair loss at a quicker rate.
The main difference between a mature hairline and a receding hairline is linked to a genetic predisposition to balding in men with a receding hairline, but other differences include the rate of hairline recession and age.
