Hi
I have my hair highlighted with with Magma and bleach to get it to a blonde (as i have a base of between a 4 and 5 so its quite dark)and all colouring processes will make your hair "feel" different, i keep my own hair well conditioned and make sure I only have the regrowth bleached each visit, all hairdressers will tell you never ever have bleach put on again on already bleached hair, if this makes sense to you. Or youll end up with breakage.
A good reputable salon will advise you. But once you have bleached/coloured hair you must condition and look after your hair and have regular trims to keep it in good shape.
