hi nadine13
I don't say that i am the expert here, ok? but
before you decide what treatment you should use or conditioner, you should analyze the problem and the cause of your hair fall.
it may be just the water in your area that contains high TDS, or simply that you are using the shampoo too often (should not b used more than once/3days) depending on your hair type.
each hair type requires different care process.
you should tell us first what type is your hair
Second how long is it.
the type of water you are using.
do you tigh your hair before properly drying it? if not it will form fungus which will cause in her fall.
do you use soap on your hair? that is bad too(soap is for body only)
a lot more to discuss ... so tell us more about your hair 1st then well try to do better I hope.
solving an unknown problem is nearly impossible dear.
you start describing your problem specifically and tell us what you do to your hair to maintain it to give us a good vision on your case.
bye for now.
