Overnight miracle required please

[Mosman]

I have a BIG meeting in the morning and have just caught sight of myself ..., I look like shite.
So I've bought a very nice smart dress I am hoping will hide the 20lbs I've put on but I had my hair "highlighted" on Saturday and it's turned to yellow and orange straw. I washed it myself for the first time this morning and it really does look bad, all the wave and curl has gone and it just looks awful.
What can I do ?
My eyes also look blood shot which is not helping at all

Look clean and smart and hold your head up high. I am sure you will be great!

Maybe tie your hair up if its not looking as you would like it to.
Get some moisture into your skin tonight. And get some sleep.
Good luck tomorrow

Get the olive oil out of your kitchen cupboard - pour about a teaspoonful into your hands and smooth all over your hair. Leave it on overnight, tied back if you want. (Worry about washing your pillowcase tomorrow night ) It'll look and feel horrible, but when you wash and condition as normal in the morning it will be a swishy wonder.

I promise.

Thank you the olive oil was remarkably effective I shall be doing that again

try coconut oil next time, smells better and is less 'oily'
