hair coloring

My hair dressor took my dark blonde hair that had mega highlights in it and colored it tea color. This made my hair look dark red and I hated it. I colored my hair a hi lift blonde but it turned a golden blonde with red tones, so I put blonde hilights in that to cover it up. My hair is now multiple shades of blonde. I want to go platinum blonde all over but will I have to double process my hair. I used professional colors by lorel and clariol that I got from a beuty supply house. How can I achieve what I want and what is the best products to use. I condition my hair all the time so it is not that damages looking.
