Q. Does using hair shampoo and conditioner too often or in too excess cass hair loss?

A. Chemicals used for dying, tinting, bleaching, straightening or permanent waves can cause hair to become damaged and break off if they are overused or used incorrectly. Overstyling and excessive brushing also can cause hair to fall out if the hair shaft becomes damaged.
so it really depends on which shampoo you are using and what are the materials inside it. i heard from more then one hair dresser that conditioner can cause it and shampoo for dry hair that also contains conditioner. but it could be just an urban legend...
