Your friend can have a doctor remove it with a bulb syringe filled with warm water and hydrogen peroxide. There are self-use syringes that require only warm water, and can be used while in the shower.
Use peroxide daily to get the wax out of your ear.
Probably a q-tip when your ear is a little wet
Hold a warm wet paper towel on the back of your ear
When you get out of the bathtub or pool when your ear is wet inside take your finger and just move it around inside your ear and it might get it out
I have to disagree with those recommending peroxide in your ears. There are a couple of things to know about. One, why do you think your ears have excess wax in the first place, they are quite capable of self cleaning. The best piece of advice regarding putting things like q tips in your ears is don't DO IT. The structures and tissues of your ears are delicate and easily damaged (that's why I wouldn't put a bleach like hydrogen peroxide in there, it may work but can cause other problems) never poke around in your ears, an old doctor friend of mine used to tell people " don't put anything in your ear smaller than your elbow".. Good advice if you follow. If you do have excess wax, i.e. It interferes with your hearing, drip in a little warm olive oil (to soften the wax) twice a day for 3 or 4 days (a small spoon held over a kettle spout will do it) then go and have then cleared by a professional doctor or nurse with a device made for the task and used correctly. You only get one set of ears to last you a lifetime, look after them.
