Hair Problems from Bleaching

I am a male and I did a bad job of bleaching my hair and it burned my scalp. When I used the bleach I used it only on the top of my head. The hair on the top of my head seems to be growing slower than the back and sides where I applied the bleach. I am only 18 so can the hair loss be due to the bleach?

It would be unusual for any long term damage from a single bleaching episode on your hair. Assuming that you wait a year or so, everything should resolve. Make sure that you do not have male genetic hair loss, by getting your head mapped out for minaturization. If you do have genetic hair loss, thinning could have been precipitated by the bleaching and proper medications may be in order (like Propecia). Get a good doctor to evaluate you.
