Red to blond--is it possible?

My daughter has medium long, fine hair which is naturally a light brown color. It is in pretty good condition except for the last three or four inches on the ends which are sort of dry and split. She had lots of blond highlights until a few months ago when she had it colored red all over with permanent color. She has maintained it but now wants to go to all over blond color. Is this possible without totally damaging her hair?

We have discussed with three hairdressers and have gotten three different recommendations. One said to go back to blond highlights over the red (she doesn`t want highlights), one said to strip the red which would be difficult and could be damaging, and one said don`t do it.

Has anyone had any experience with this?

Thank you for the advice. I think that is what we will do. I hope her hair can handle it.
