i did ionic straightening few years back. hmm... personally, at that time, i don't think it's worth it, cus after few months, it's obvious your roots aren't as straight as the lower ends. but since now the prices have dropped significantly, it's still worth a try.
but now, my hair is now thinner, & straighter (人老了。。。唉), so now, i don't need to go for ionic straightening. however, recently, i have bought a professional hair straightener.... & it works sooooo well. if i use it to straighten my hair, it will look like 負離子.
eeee
憎死你!!!!
and NO, i did not burn my hair again. not with the straightener. actually, sometimes i'm so careful in using my new straightener, cus it's soooo hot cus it's professional, i really do NOT wanna burn my hair again
