text: my daughter is just 11 yrs old,but she already has this not-so-good -smell in her armpits...? i hand-washed all her underwears.. i think anti-pespirant is a lot more effective than just deodorant. you can also find some crystalised salt (most times it's sold in a solid crystal tube) - activate by rinsing under the tap and apply - has no smell but it effectively eliminates the bacteria under the arms that cause the smell. that might be a better alternative for your daughter since it's natural.
