Some that I am aware of are straightening or curling your hair without an anti serum in your hair, bleaching your hair because it destroys the colour there.

Of course! But its acidity may damage your hair!
You may go ahead and do this, but it is not recommended. It may cause permanent damage to your hair.
It is depending on what hair dye you get. Make sure not to dye your hair to many times in a month or it may damage your hair.
excessive use may damage your hair,but use in moderation,and make sure they are alcohol free.
If bleach (or lightener) is left on the hair for an extended period of time, severe damage may occur to the hair, or worse, the hair may break off completely.
