I have to tell you..I have THE straightest hair on the planet..that doesn't take any curl whatsoever at all! The ONLY curl I could keep was using rollers that I slept in overnight and then my hair looked awful!
This is NOT under $100 but worth EVERY penny!!
The Instyler! There are infomercials on it and it's on HSN too I believe. You actually get 2 of them from the infomercial for like $140 I believe.
At first I was like.."I don't want or need 2!" but got it anyway. LET ME TELL YOU!! I'm SOOOO glad I got 2! I have used the Instyler EVERY SINGLE DAY without fail for easily over 4 years and my hair is SILKY and gorgeous! Everyone asks me what I use! The instyler actually makes your hair shiny and curly at the same time. It is one item I will NEVER EVER ever be without!
I have bought 2 sets of 2 (my first one finally went on the fritz after about 2.5 years) and I liked having 2 for travel. I still have 3 working irons, and would pay TWICE what they ask for...that is how much I love this iron.
There is also a money back guarantee on it..so if you don't like it you could send it back. Cannot recommend this item highly enough! I can go without makeup and designer clothes..but never my Instyler!
