why do i have damaged hair when i hardly straighten it?
I only sometimes straighten the top but most of my top layers are damaged even though i dont straighten them.
It may be from mechanical damage from over- manipulation, but - assuming you aren't always tugging a prodding and etc. you hair - it's probably heat damage. Heat damage can occur from using a flat iron - or blow dryer or curling iron or hot comb or etc. - just once.
