Nothing says summer more than lightly tousled, care-free waves. And the ones models sported at Anna Sui's Spring/Summer 2011 collection gave me some major hair envy. I just had to know how to get this look at home, so I enlisted the help of Lorraine McAndrew, Vidal Sassoon Salon’s creative director in downtown Toronto. She gives her tips on getting this gorgeous summer hair look and though she says it works best on people with medium to thick naturally wavy hair, we also have some tips for those with straighter locks. Check it out below!

"It has a light easy flow to it which will work well with summer clothing." For naturally wavy hair: Step 1: Start with damp, towel-dried hair, parted in the middle. Apply mousse (McAndrew loves Kerastase hair care products and suggests their mousse to create texture and hold). Comb the mouse through the hair to make sure it is distributed evenly from top to bottom. Step 2: If you can let your hair air dry to get a natural wave, great. If not use a diffuser on a hair dryer to create natural-looking waves minus the frizz. You can scrunch the hair slightly to create more wave. Step 3: Finish hair with hairspray to give extra hold and to create a piecey look. Step 4: Top with a floral head band or clip, or leave your hair free of accessories. For straight hair: Step 1: Part towel-dried hair down the middle. Blow dry hair using Chroma Thermique from Kerastase (a leave-in cream that protects against styling for a soft, touchable finish. Bonus -- it also protects colour). Step 2: Straight-haired girls will need a little help from a styling tool -- so bring out a curling iron! Using a large curling iron wrap the hair around the iron and hold for a few minutes, to create soft, natural waves. Continue this process through hair. Step 3: To create a more natural, free-flowing look, separate the hair using fingers. Step 4: Finish the look with a touch of hair spray to ensure the waves hold in your hair. And if you're like me, I'm always looking for ways to take my day-time hair to night without much fuss. McAndrew gives a simple tip to amp up the volume and sexiness to this look for evening. Take it from day to night: "I would take this from day to night by changing the part; by moving the part from the centre to the side it would create interest and become more of an evening look. Side parts create more contrast over the face with the hair coming over the eye and have a polished effect," she suggests. Easy! What do you think of this look? Would you wear it to the office?
