I think its mainly because she kinda starts to want to look pretty too. She's been overshadowed by Carly and the guys that always crush on her (including Freddie), and she wants to look just as beautiful too (not that she wasn't, Seasons 1-3).

Or, Jennette's hair/makeup person got a bonus (IDK :P)
