You won't believe how much Kylie Jenner's birthday hair extensions cost

It’s no secret Kylie Jenner just turned 21 – and if you didn’t know have you been living under a rock?

Her lavish pink themed birthday bash was posted all over social media and clearly no expense was spared.

The party was that poppin’ that some people didn’t even last until the end of the night – er, hey Tammy Hembrow.

It wasn’t just the bash itself which was out of this world, Kylie’s outfits and hair were brilliantly OTT too.

Showing off her new blonde locks on the night of her party, the 21-year-old put Ariana Grande to shame in the hair extension department and wowzers did they cost a lot.

Her extension artist – because apparently that’s a legit thing nowadays – spilled the beans to Refinery29 on just how much Kylie splurged on the hair.

Violet Teriti revealed Kylie’s extensions weighed about 400 grams and made from “Slavic hair sourced from Russia”.

These specific type of locks at this weight are sold from anywhere between $8000 to $11,000 ($6000 to $8000 USD). Um, sorry…WHAT.

For the average Sydneysider that’s four to six months rent gone on Slavic hair.

But let’s remember Kylie’s a billionaire so it probably didn’t even make a dent in the bank.

How depressing.
