That "blink of an eye" moment you´re talking about, is just the artsyle of a manga talking... His hair was covered in blood at the time, making it dark "instantly"... after that, it was a timeskip, so he just watched his hair and let it grow all black with time until we saw him again.

Mystery solved.
