Itchy ears can be really irritating. There are several reasons you could need itchy ear treatment, for example, if you have an ear infection. Sometimes prevention is better than cure!
It may be the case that your ears are itchy because something is irritating them. Soap and shampoo are prime suspects. When you have a shower you might be getting shampoo in your ears. Even a tiny amount can be enough to set off dermatitis in your ears. Once inflammation has set in it may flare easily in response to things which don't usually irritate them.
Once you have itchy ears it is worth guarding them carefully. You can wear waterproof ear plugs such as ours from http://zenplugs.com/molded-earplugs/ in the bath and shower to keep water and soap out. Don't soak your ears in the bath. Bubble bath is one of the worst culprits here. Even without soap in the water you could still end up with sore ears from the warm water. There may also be germs and traces of cleaning products in the water. ZenPlugs Ear Plugs are also antibacterial which help reduce the itch.
Itchy ears can be caused by eczema. This is a disorder of the skin where it becomes red, inflamed, itchy and flaky. It can be set off by an allergy or by soaps and shampoos. If you have eczema in your ears you may need some treatment from your GP. This is why it is important to visit your doctor if you have a problem. They will examine your ears and if it looks like there is eczema or psoriasis they may give you drops. These may contain an antibiotic such as gentamicin and a steroid such as hydrocortisone. Acetic acid is sometimes included as an anti-fungal agent. The common name for this is vinegar.
Swimming can also cause blocked ears. If you have narrowed ear canals or if you have surfer's ear then water can get into your canals but may have some difficulty getting out. They remain wet and clogged for some time afterwards. Try tilting your head from side to side to get the water out. You can pull your ear in different directions also to help free the water.
Surfer's ear is a condition where the cold wind and sea water chill the ear and the surrounding area. This results in the body forming bony outgrowths around the entrance to the canal. This narrows, leading to deafness. They take longer to dry out, leading to clogging. Wear surfing earplugs and a cap regularly whilst surfing to prevent the condition.
