Hi,
I wear my hair short and have no trouble concealing my BAHA -- my processor is the Intenso model, which is larger than the Divino model. There's a good range of processor colors -- I have the brown which matches my hair color quite well. The abutment -- the titanium thing that's attached to your head is quite unobtrusive. I have to say that the thought of having an implant in my skull seemed a bit creepy at first -- but the reality is that it's no big deal.
The processor is not water proof, though I met someone yesterday who accidentally jumped in a swimming pool with his processor attached ... realized it as soon as he hit the water, got out immediately and dried the processor with a hair dryer. He said it's been working fine ever since. I don't plan on trying that out. But the story presents a good point -- you get so used to wearing the processor that you aren't really aware of it.
Re: the cleaning process -- I wash my hair every day and have had absolutely no problems with infection (knock on wood); a soft toothbrush is supplied by the manufacturer, but (per my doctor's advice, by the way) I've never had to use it. I remember using a little bit of antibiotic for a couple of days after the surgery, but have used nothing since. I believe that some people have occasional problems with tenderness or infection -- I'm among those who don't. In general, I think of my BAHA as analagous to my contact lenses --- I'm extremely careful with the equipment, wash my hands thoroughly, and have a set routine. I've been using my BAHA since June, I really like it, and I don't even think about it that much anymore -- it's become part of my life.
Best wishes as you make your decision!
