The famed Cannes International Film Festival that's held in the French Riviera every year, is scheduled to commence May 16 this year.

Apart from Indian films being included for screenings and competition, Aishwarya Rai Bachchan's appearance at the fest is one of the talking points, like every year.

While the actress got on a wrong foot during her early days in Cannes, her transformation into an international celebrity has been astounding. Apart from wearing the most renowned designers, she has also experimented with hairdos quite well.

Here's looking at Aishwarya's Cannes highlights, hair-wise!

Ms Firece

Ash came out of her comfort zone and put on an edgy Armani Prive gown as she attended the premiere of Sleeping Beauty on day two of Cannes last year.

Her tight updo complemented her outfit really well. This is one side of the actress we'd love to see more often.

In what could be best described as a dream-like first appearance, Aishwarya took the Cannes red carpet by storm in a gorgeous Elli Saab gown in 2011.

Her wavy updo was the epitomy of elegance and great style. The fact that she was around two months pregnant only made her even more radiant.

For the Raavan photocall that she attended with hubby Abhishek Bachchan, Ash chose a black Gucci dress and T-strap sandals.

Her soft curls put a Bollywood spin on the western look.

Ash wore a pink Gucci gown for the premiere of Wall Street: Money Never Sleeps at the 63rd Cannes Film Festival in 2010.

The understated ponytail was a great choice to go with the outfit.

The L'Oreal brand Ambassador looked bewitching in a black Armani Prive evening gown ala Morticia Addams on day two of Cannes in 2010.

Her low bun and black floral hair accessory was a fun addition to the enigmatic look.

Ash seems to favour the bouffant the most for her Cannes outings.

Only this one slightly missed the marked.

Her majestic Elli Saab gown, however, saved the day at the Cannes opening ceremony in 2010.

Wearing her favourite designer for Cannes -- Ellie Saab -- Ash attended the 62nd edition of the festival with hubby Abhishek Bachchan.

Her slick pony accentuated her pretty face.

The actress was quite a tease in a strapless Roberto Cavalli number as she attended the opening ceremony in 2009.

Her cute braided bun accessorised with a jewelled hairpin was a hit with the dress and her diamond encrusted pearl drop earrings.

The actress wore a floral dress to the photocall of her film Provoked at Cannes in 2006.

After suffering a couple of setbacks fashion-wise, she chose to keep it simple by leaving her hair loose.

The actress wore a Neeta Lulla number with Chopard jewels for her 2004 Cannes outing.

The curly hair tried to take some heat off the daring dress with little success.
