Can one's hair color change if one straightens it or uses a hair dryer to dry it unhealthily or frequently?

I sometimes use my straightner to dry my hair....I straighten my hair, but sometimes it's wet when I start, so I end up going over the same strand 5ish times--sometimes more than that....and when I first began to straighten my hair, I didn't use an anti-humidity spray. When I used to use a hair dryer, I always used to set it to the highest temperature.Can one's hair color change if one straightens it or uses a hair dryer to dry it unhealthily or frequently?
It wont change colour but it will damage it, try to use heat protection sprays when straightening it.
