I really like teal, but I think I would rather do a solid tone the first time. But maybe in the future! Idk if I would go with more frequent streaks or more infrequent. But I am in love with teal for hair! It's so GORGEOUS imo! 
You won't get teal on your hair, unfortunately, not without bleaching. Teal only really looks good on a basically white base. If your hair is dark blonde/light brown, it'll just look like a muddy swamp. :( Believe me, I've tried lol - my natural hair goes from dark blonde in winter to a lighter blonde in summer, but even at its lightest in summer, any attempts at teal just look muddy unless I've bleached it first.
One thing you can do if you're wary of bleach, is to just do the tips. First time I did this because I really REALLY wanted a vibrant turquoise was to just bleach the bottom 1-2 inches, then I could do any dye colours I liked when each one washed out, then at the end of the summer (back to work, boooooo) I just had a trim like I'd normally do and cut off 2 inches of bleached hair - no damage to the rest
