so, i own this product
http://www.philips.com.sg/c/haircare/salonstraight-seduce-210degreec-ceramic-straight-curl-hp4668_29/prd/

and when i used it, it made my hair fall out bad, and my hair doesn't fall that much so i just quit using it for a long time. quite some time ago i started hitting the salons again and i figured out that i must always get my hair straighten. So should i get back to my old straightener or go to the salons?
or should i use like leave in condition before using it or what ?

i won't buy a new straightener cause i am getting a perm both ways - and i hope it will be soon enough - THANKS ALL ^^
