Good Straightening Serum?

So, I've been wearing Marley Twists for about 2 months now. I plan on taking them out within the next day or so to do a good wash as well as straightening my hair for a real length check & trim. Can anyone recommend a good straightening serum that isn't too heavy but actually lasts?

I remember back in the day Sabino (sp) was the go-to brand but they've since changed their formula etc etc.

TIA!

I'm more focused on anti humidity. Sometimes I get so hot while doing the flatiron that my edges revert a bit before I finish. 

Yep, co-signing on Chi Silk Infusion, have used other stuff, but nothing does it like that, a little goes a long way, after I run out of the frizz ease serum(John Frieda, I heard good things about it so I got it and it's not bad but CSI is just better in my opinion, but also more expensive though) I'm going back to CSI.
But if you are looking for a less pricy solution, the IC Fantasia serums(I have no experience with the heat protecting spray though, here they used to have the serum in the pink bottle but now they only sell the pink spray, don't know about the U.S. though) are great as well in my experience but you will only have to use one small drop and rub it in your hands real good before putting it on your hair (just noticed you asked for a product that isn't too heavy.)
Another good option which is cheaper than the Chi silk infusion also from the Chi line is biosilk, it is not as heavy as the Chi silk infusion and less expensive.

You're welcome, you'll be back on track in no time.

Chi is great

Paul Mitchell is also amazing. I think I like the PM better.
