Why is my skin so irritated and itchy?

I used to bath everyday, I itched all the time, I switched to every other day with a sponge bath inbetween. My skin don't itch so much, I was drying it out by bathing so much. also put lotion on your skin after you shower, that will help. when you have dry skin, it seems that things like dog dander will effect you more that ever before. So on and so forth. like many other things with affect you more, if your system is weakended for some reason. That goes for washing your hair also, daily washing will dry up your scalp cause ing dandruft. Well thatw one of many reasons.
