I'm hoping to get a little advise and I don't even know where to begin looking for answers ...  So I am hoping there is someone here that may have experience with alternate hair coloring.

2 days ago I dyed my hair Atomic Pink. It was the first time I have dyed my hair besides when I had dread locks so I wasn't really sure what I was doing. My first mistake was starting at 10 at night. My second mistake was only buying 1 bottle of bleach out since my hair is really long and really thick. My 3rd mistake was letting my Boyfriend do the back for me. In the end it doesn't look too bad but there is still alot of brown streaks that I would rather not have. SO i am going to let my hair have a 2 week break bleach it out again and do it over. And this time I want to do it right. So here is what i need to know

1st will it be okay to bleach my hair twice in 2 weeks. My hair is not so healthy and i don't care much about it as long as it doesn't fall out or anything

2nd I used Special Effects brand dye which is supposed to last at least 6 weeks it's a semi permanent dye. It's only been 3 days & I've washed my hair only once since I washed it after the dye job and the color is already fading out in several places leaving me with pale yellow spotting. Not to mention that color pours out everytime I shower .. shampoo or not.

When i do it the next time i would like to use a brand that will last more than a couple days and not ruin my tub ... yes i have a nice new pink tub and shower curtain lol my landlord is gana love that. Do they make a REAL PERMANENT dye or are semi permanent all you can get. What brand can I use that will last the 6 weeks it should?

and last question ... i spent nearly 40.00 on this 3 day spotted dye job. I am looking to spend close to 60.00 this next time. So if anyone know any tips for cutting my cost back that would be super too.

thanks in advance
