I have questions about going dark/medium brown to blonde?! PLEASE HELP?

Understand that you are going to ruin your hair to do this. You have a lot of hair, and its thick. You're going to have to strip the color out, tone it, and then color it. After that, in order to keep that look, you're going to have to go back and do that every 4-6 weeks, depending on how fast your hair grows. For the intial treatment, (in my area) you're looking at $75, bare minimum. Then factor in $50 or so for highlight touchups every few weeks. Not to mention that this style needs constant and regular upkeep. So factor in another $30 or so for the cut, every 6-8 weeks, again depending on how fast it grows. This style also requires a blow-dryer, and looking at your hair, likely a straightener, as you've a fair amount of natural wave. So, all in all, I can tell you that its going to be hell on your hair, and your pocketbook. I'm not saying dont do it, just ask yourself if its actually worth having crispy hair and no money for anything else. Your best bet is to go to a stylist, and actually talk about it. Most consultations are free.

It should only take one visit and it should cost 150 to 180. Depends where you live. Make sure you go somewhere good.

just ask the salon people .
