summerize
To gradually prepare yourself for the warmer sunnier months, such as gently "breaking in" your complexion for tanning without peeling.
Initially I wear my white sunhat all the time whenever I go outdoors in late Spring so that my "chrome dome" doesn't get sunburned, but then as the days get even warmer, I alternately take off the hat and then put it back on a few minutes later, in an effort to summerize my scalp; eventually when I get a fairly even tan "up there", I can leave my hat off for hours at a time without excessive reddening.
