People who bald early and aggressively often have these dry scalps with a lot of dandruff. A lot of us report that the area that will soon bald will tingle, or burn, or be sensitive.
well i'm 20 n started losing at 16 or 17 and i remember noticing for the first time the INSANE amount of burning red flaking on my scalp. I asked my bald dad who lost it early who told me he had exactly the same thing when he was my age.... hmmmm.
btw if you have itchy scalp with dandruff USE apple cider vinegar mixed in water to about a 1:6 ratio. sorts it out completely.
