Kate Beckinsale
The classic, gym-appropriate hairstyle, the ponytail is versatile no matter the occassion. What makes Kate's so pretty? It's messy and voluminous. What does this mean for you? Keep the dry shampoo spraying.
Lorde
This is a wake-up-and-go type of hairstyle. Is your hair dirty from yesterday's activities? Good! Apply dry shampoo to volumize your tresses and change the hair part by flipping your hair around throughout the day. You'll have that indie edge in no time.
Miley Cyrus
Even if your hair is fried, multiple colors or just not working with you, wearing a hat gives the illusion that everything underneath is behaving like it should. For more dimension, add in a micro-braid, like the singer did, to give you that boho feel.
Camila Cabello
If your hair is naturally straight but coarse, the "Bad Things" singer's hairstyle is for you. The more texture you have in your hair, the better, but make sure to tame the fly-aways with a small dollop of hair serum. You don't want to use a product with high alcohol content.
Lea Michele
Whether you have Lea's stylist, Sarah Potempa, by your side or you're a twist-tie-go type of girl, the top knot looks great in any condition. To get your hair as sleek the actress', part your hair in the center, straighten with flat-iron, smooth fly-aways out with a hair paste and twist up into a knot. Easy-peasy.
Madison Beer
If your hair is natural curly or wavy, this one might not be for you. However, if you have slick-straight strands, like the actress/singer did at the Billboard Music Awards, you only need to air-dry and go.
Halsey
Everyone is shaving it off, from Cara Delevingne and Kristin Stewart to Lupita Nyong'o. Need another reason to aboard this trend train? You literally don't have to do anything to look inherently badass. Lazy looks good on you.
