Hair product fail!!

Hi guys :)
uhh im sooo mad/sad right now lol
So last week i bought a bottle of the very expensive Biosilk.
I got to use it once and i stupidly never closed it all the way :(
just a few mins ago i went to use some and found it tipped over with the full thing wasted all over my nightstand and and absorbed by my nightstand table cloth and my Sims 3 Cd case insert :( uhhhh im sooo sad, the one time i used it i loved it and now i have no extra money to replace it ..BOOO

Also i have decided to stop flat ironing my hair:) my hair is/was naturally verrry curly, and i mean curly little frizzy sprial curls!!
I hated it so i flat ironed my just about every day for years. I would leave it curly sometime when i had the right products to make my curls more defined and not frizzy but most of the time it was just a big frizzy mess and too hard to manage, which is why i liked it straight better.

After i had my son my hair just randomly went straight :O
im serious! i just washed my hair one night and when it dried it was completly straight!! i was realllly happy actually lol
i thought it was the new shampoo i used (it was called straight styles something or other) however after washing my hair numerous times after with different shampoo (even curl defining ones) I have come to realize my hair lost its curl because its FRIED!!

As first i didn't care i just figured its just as well, i like it straight better anyway but after a few months i'm really starting to miss my curl :(
i'm finding every time i go out now i'm wanting to curl my hair instead of flat ironing it. But that is frying my hair even more and i figure if i ever want my natural curl back than i have to stop with the heat styles now before all the new root growth gets just a damaged as the rest of it..

so my new thing now is after i wash my hair i put it up in either a big tightly twisted bun or a bunch of little buns and let it dry over night, that way when i wakeup the next day i have either big curls or little curls with out any heat:)

My problem now? I have to use some kind of serum to keep my hair from getting frizzy and guess what? I wasted it all :( boooo
