I started with blonde hair. I had it died brown and then eventually black in about 5 box kit colorings. 2 or 3 weekes later after I had it died black I had it stripped, colored and highlighted at a hairdressers. The stripping did a lot of damage to my hair. Its been 1 or 2 months sience then and my hair still falls out a lot. So anyway my question is how long should I wait to dye it from a box kit again. I want to get a better color of blonde. And then after that I was thinking of maybe getting blue highlights. I would like your opionion on the blue highlights as well. Thankss.:p

My suggestion would be to not color the hair for a long while until it grows out. Keep cutting it in some sort of cute style and wait until you have cut off all the damaged hair.
What is your original color? If you are blonde then lightnening it a bit might work well. Blue highlights sound interesting if you are under 35 or so and if your job/school are o.k. with it.

Honestly. The worst thing you can use on your hair is a box kit. Anytime you get your hair dyed get it done professionally. And getting your hair stripped is never a good thing you shouldn't get anything done to your hair for maybe like 5 months after you hair stops falling out finally all together.

If you keep dyeing your hair with at-home box colors, your will severely damage it. If you want a decent blonde color, you will need to do a double process, bleaching and toning. This is where your hair is lightened with bleach and then a toner is applied to tone down any brassiness and make your hair look natural. You should consider letting a professional do your hair.
