Get an application for a reddish deodorants, pruritic rash in the Achselgegend, then you are probably victims of an allergy.
Most doctors and pharmacists advise in such a case for the use of "soft" or "mild" Deos without fragrances and alcohol.
If this is you do not help, then you may be allergic to aluminium. This is in the form of aluminum oxide or Aluminiumhydroxychlorid (an aluminum salt) in almost every deodorant, even in the supposedly soft.
Ask at the pharmacy without Deos specifically for aluminum. If your pharmacist can not help, then ask, for example, a deodorant company Vichy. However, this at a price of nearly 15 Mark quite expensive.
