The Hunger Games' Jennifer Lawrence needed those long locks for her character's signature side braid. But we personally love when this up-and-comer goes blonde with soft, wispy waves. Long hair tends to have more breakage, so to keep stragglers in place, try John Freida Touch-Up Flyaway Tamer ($5.99, target.com).
Who doesn't envy The Vampire Diaries' Nina Dobrev's long, flowing strands, whether they're down or in an intricate fishtail braid? She's revealed that the secret to her healthy hair is the result of advice that came from her mother. Use a hair mask every third wash. We love the MoroccanOil Restorative Hair Mask ($41, beautycollection).
There is no denying that Blake Lively's long golden locks always have volume! To get soft waves like this Gossip Girl star, wrap large sections of dry hair around a 1.5 inch curling iron. Then, spritz with Oribe Dry Texturizing Spray ($39, barneys.com) to create voluminous haphazard waves.
Julia Roberts has always been known for her long, sexy hair ever since her Pretty Woman days. A trick to steal from this hair icon: by parting her hair in the middle at the Mirror Mirror premiere, she dressed down her perfectly primped curls for a spring bohemian look.
Taylor Swift has long perfect curls, but what we love most about them is that they also straighten out so perfectly. To get that smooth texture, use Trsemm Smoothing Crme ($4.99, ulta.com) on towel-dried hair. Rub a few drops on ends to protect from breakage.
We love how The Descendants actress always has such carefree piecey waves. To recreate, braid your hair the night before, let loose in the morning and spritz with Aquage Sea Salt Texturizing Spray ($18, drugstore.com).
Kim K has always had Rapunzel-esque hair but her new blunt bangs add dimension and edge. Be sure to flat-iron bangs and spray them with Ion Dry Shampoo ($5.59, sallybeauty.com) to counteract the shine from the heat.
The Bridesmaids actress went for big, billowy curls instead of her normally straight hair for the 2012 Academy Awards. When using a curling iron, spritz your strands with a heat protectant spray, such as Oscar Blandi Dry Styling Heat Protect Spray ($23, macys.com), to combat heat and boost shine.
It is never easy to keep long locks like Demi Lovato's healthy after repeated dye jobs that reap hair of hydration. Use Avon Advance Techniques Professional Hair Color ($7.99, shop.avon.com) for a gentle at-home dye job that'll keep moisture in your hair.
