Jessica Alba could not look cuter wearing her hair in this half-up, half-down style. By creating a little volume and adding some curl, she dressed up a relatively casual look.
To duplicate her 'do, begin by curling two-inch sections with a large-barreled curling iron. Next, backcomb hair through the crown to add texture and volume and spritz with a little hairspray.
Then, make a center part, section out bangs or tresses around the front hairline and pull back all the hair from the top of the head and secure in a loose ponytail. The hair around the face can be pulled back and pinned behind the ears or left to frame the face.
We've spotted other celebrities with a similar look, including Jessica Alba, Jennifer Hudson and Pippa Middleton. Check out all the pictures in the Half Up Half Down Hairstyles Lookbook.
