Right soo.. I've been trying to bid on some TIGI Catwalk Curls stuff on ebay but it always goes way too high..
I was going to get the Booster, Moisturiser and/or Amplifier, so I'll list their descriptions and then you gals can give me some alternatives!

Booster-
Scrunching Gel With Attitude

Blast in massive flirty curls with this spray in booster! Curls will have tighter, more defined shape, shine and definition. Lose the frizz factor. Your hair will have it goin’ on!

Amplifier-
It’s gonna rock your curls! This amplifying cream will define and separate curls and waves while adding volume, texture and shine.

Pump 1 or 2 times depending on the length of your hair. Work through wet hair and diffuse for medium hold.

Moisturiser-
For soft, natural, sassy curls, use Curls Rock Shampoo, Conditioner and Leave-In Moisturiser. Let hair dry naturally or diffuse. Leave-In Moisturiser will condition your hair while locking in moisture.

So yeah... recommendations for similar products?

i used to use one by some super expensive hairdresser type brand hang on.

KMS california curl up control creme

it smells good and made my hair pretty, but i think its about $25 a pop or more.

I don't use any special product for my curly hair apart from the shampoo, and that's why it's ugly--my fault

what do you recommend? spray, cream or mousse?

I think its called Olive tree...but its by YY. Unfortunately its really expensive...but if you have the money ever, its seriously the best.
