Is this enough protection for my hair?

I dye my roots every 3 weeks or so (ammonia free dye), and my whole head 2x / year. I blow dry every other day, and straighten about 4x a week. I get my ends cut every 4-5 weeks, and use a deep conditioner once a week. When I straighten or blowdry I use heat glide heat protectact and smooth serums, yet my hair still seems to dry out. what else can i do ?
