Can you get a perm like this?

As a cosmetologist I will tell you, you cannot get that look from a perm. Your best bet is to get yourself a good flat iron... Selena's hair looks to me like it was curled with a flat iron. You will need some product, Vavoom by Matrix is an awesome line for styling. Start with the shampoo and conditioner and then the root riser. Apply the 'Blow in Volume' before you blow dry and then curl your hair in sections with your flat iron, you may also try the 'Iron in Volume' as it will protect your hair from all that heat!! All of these products are by vavoom. You can by them at most salons, I know that Great Clips sells it, and if they do not have it they should be able to order it for you. DO NOT buy any professional hair products from anywhere but a salon, the products are sometimes contaminated, expired, or something completely different than what you paid for!
