No, you cannot replace re:coil
with Tweek because Tweek is more of a finishing product. I use re:coil
after Curlkeeper, while my hair is still wet, to give structure to my curls.
I, too, like the smell of Curlkeeper and Tweek. I don't know why some people don't like it, but it does have a distinctive smell when you put it on. The smell goes away immediately, IMO.
I would like to try some of their other products, but I am so in love with Deva One Condition
and Angell (especially love the smell of Angell) that I hate to spend money on something else only to find that I don't like it as much!
My hair is very thick and requires several large handfuls of Curlkeeper, so it can get expensive. An 8 oz bottle lasts a little less than 2 months=$15.50 plus shipping.
Thankfully, the Tweek is a hand-me-down from someone who couldn't get it to work for her hair, because that little 4 oz bottle is $19.95 plus shipping. That's a lotta $$$ for a poor grad student, but worth it for the happy curls.
