Apart from it making plot sense (at a Doylist level) -- are there any good Watsonian explanations of why it's Rowan and Nicola, and of how Nicola's hair has managed to grow noticeably longer than Lawrie's in the first place?
There's actually no reason to expect hair to grow at the same rate, even in identical twins. Monozygotic twins are nearly identical genetically, but there are still random mutations during replication that mean they are slightly different. They will also have different phenotypes, particularly so with girls because in girls one of the X chromosomes will be deactivated and it might be the opposite one in a pair of identical girls.
I have no idea how many factors control hair growth, but it's not implausible the Nick's might just grow much faster than Lawrie's.
However the explanation that Lawrie might have needed clipping after the car accident could work too.
