When it comes to summer-appropriate hairstyles, we all long for effortless and versatile, yet stylish and sexy looks. Inject some freshness and delicacy into dull hair trying one of the numerous styles spotted on the catwalks. From loose curls and the eternal braid to twisted ponytails and cute updos, here are some of the most desirable summer 2011 lovely hairstyle trends.

The super natural look with a rather messy-dressy appearance is a great option for spring/summer 2011. Summertime is all about lovely, nonchalant, fashion-forward hairstyles that require minimal effort and perfectly combine laid-back with elegant. Bouncy texture is so glam and cool this season. From big to soft, there is a style for everyone. Since it is already known that natural curls will always be alluring, if your hair is straight you can cheat a curly look too.

This season try looser, slightly tousled waves. For a lovely result, use some large heated rollers and leave them on for about 10 minutes or use a large-barreled tong and take random sections making soft curls. You'll get disheveled, yet sexy waves as seen at Etro and D&G. What's amazing is that this trend suits everyone, from those with medium-length hair to those of you who sport a cute short bob.

When the weather outside becomes warmer and more friendly, it's so sexy and lovely to wear your hair around your shoulders but making some lovely side braids for a playful look (Charlotte Ronson). Besides, braids are the easiest choice when wanting to reinvent your hair over and over again. Braided hairstyles are extremely versatile and can be fun and youthful (Lacoste), but also elegant and chic (Erdem).

There is something extremely interesting about the classic ponytail that makes this hairstyle so adorable. This gorgeous 'do can be worn day or night, but stylists give it a seasonal update coming with newer, reinterpreted versions. And even though the pony is synonym with simplicity, this style is the perfect option for a quick hair fix. At BCBG Max Azria, Céline and Brioni, the ponytail is sleek and straight with a middle parting, looking utterly lovely, yet so hot. You can make it your own by adding a hair accessory such as seen at Blugirl.

If what you want is something different and unique for those days when the heat outside becomes unbearable, try upgrading your pony and give it a twist (Nanette Lepore). For a wow-effect, the knot spotted at Michael Kors can do a nice, flirty trick, but make sure your hair has a tousled, boho texture.

Updos are not just for ballerinas or red carpet events anymore. These versatile hairstyles have become a sophisticated way to style up a boring casual appearance. Whether you opt for the simplest versions such as seen at Chloé or more complicated ones like those from Luca Luca and 3-1-Phillip Lim, there are endless possibilities for you to rock this trend. Besides, an updo is the most practical and at hand hairstyle to keep your long tresses off your back during hot summer days.
Cool and absolutely wearable for summer is also the popular top knot. Gather your hair into a ponytail onto the top of your head, twist into a bun and secure into place. For maximum comfort, avoid the too-tight-to-the-head approach and opt instead for a looser knot.

Chic and absolutely lovely is the Luca Luca 'Yacht Knot'. Despite its apparent complexity, this fabulous hairstyle can be done following a few simple steps. First of all, make loose waves using a large-barreled tong and part your hair. Next, section off the top and bottom, then twist both top sections back, pin them into a knotted bun, and wrap the remaining section around it. For a fab, sweet effect stay away from the perfectly polished finish and pull out a few wispy pieces at the hairline.
