You will not face any problem mostly because even the appearance will be slightly different, the features and recognition marks like the moles will be the same. It is better to take with you a photo with the hair and without the hair also so that the security will be able to identify that both are the same person. Also your Id proof will also helpful to identify you. So dont worry about this. If the security have doubts just cooperate with them and make them understand it is you but dont panic or get angry. But mostly there will be no such problem.
