When I introduce a character, I try to describe them.
But, then, I don't usually describe them anymore. Especially if they're not the main characters.
One of the things I dislike is when an author constantly reminds you of what the characters look like. Repeating what color eyes or hair a character has, no matter how many different ways you can say it gets boring! Yes, we know he has blue eyes because you've told us 100 times. And oh the cold skin, can't forget that. He had cold skin in the beginning of the series, he still has cold skin at the end. WOW, who would have thought?
How much do you notice you neighbor? Spouse? Someone you pass in the store? Best friend?
Other than my children and my husband, I couldn't tell you what color eyes anyone I know has. Unless maybe they were SO different, I couldn't help but notice. If a neighbor changes something about their hair, I'd notice that.
So, readers - how much do you like reading descriptions of the characters? Is there something specific you like to know? What their hair looks like in that scene? What they're wearing that day? Or does it not matter after the first major description?
How about you writers? How much description do you put in?
