Sometimes they have their stylists to blame and at others plain bad luck - no matter how hard they try even the biggest of stars have had bad hair days.

Many a times your favourite star's look leave you more shocked than surprised.

Here's a look at some of the most bizarre hair styles sported by Bollywood stars...

Aishwarya Rai Bachchan

Aishwarya, who is usually dressed to stun ended up leaving shocked.

During one of her recent social appearances in Delhi, the actress was seen sporting an all new wavy hairstyle, which look downright OTT.

To add to the torture, she had coloured her tresses. This is one look, we really don't like on you Ash.

Sonakshi Sinha

Do you want to know how to look like your own mother? Just style your hair like Sonakshi Sinha in this picture clicked at the promotional event of Lootera.

She's looking way older than her age in this center-parted coloured hair look.

Ameesha Patel

When you can match your haircolour with your lip-colour, it's time to fire your hair-stylist.

Are you listening Ameesha? Your beautiful long locks can look a lot better.

Bipasha Basu

We wonder what Bips was thinking when she decided to sport this tie-up bun hair style.

And if that fringe was added to give her that cutesy school girl look, we're sorry it is not doing any good to gorgeous Bipasha.

Deepika Padukone

Once upon a time, Deepika sported this hair style. Thank God, the hair cut vanished as quickly as the film, Chandni Chowk to China vanished from the Box Office.

We love Deepika's current hair style.

Must say the actress is giving special attention to her looks these days.

Priyanka Chopra

It seems Bollywood actresses have a curl-fixation.

But unfortunately very few get them right.

Just like Sonakshi and Aishwarya even Priyanka sported the curly hair look in 'Salaam E Ishq' and she looked horrendous.

We're sure she must have changed her stylist post this disaster of a look.

Sonam Kapoor

Even Sonam would want to erase all the memories of sporting this hair style.

In a wake to look effortlessly styled, Sonam looks careless styled in this picture.

Kangana Ranaut

The 'Queen' Kangana is known as a fashionista who doesn't mind experimenting with her looks.

But this strange hairstyle is a total disaster. You can do a lot better, Kangy.

Kareena Kapoor

We know Bebo can carry any hair colour but what even she needs to make that perfect style statement is regular touch up.

You are the Kareena Kapoor, you can't afford to step out like this.

Amrita Rao

Spare us the horror! Where did your comb go Amrita.

You look like you've just stepped out of a roller coaster ride.

Fire your stylist, now!

Vidya Balan

This hair style sported by Vidya is clear evidence of the fact that she tried really hard to look young when casted opposite Shahid Kapoor in Kismat Connection and it was an epic fail.
