H.R. Wet hair could develop into a good thread. Cervia has a nice full bush that shows up nicely when her hair is wet.
I was at a beach recently and saw many girls walking on the beach with their hair pinned up. I would say 1 in 20 had hair that grew low on their neck and 1 in 75 had hair on their neck that was abundant and curly. In the latter group, their hair looked like an explosion of hair on their lower neck. One girl in patricular had black hair and it was curly and low across the whole lower neck. (not just two points growing down in a "V"). You just wonder how low her hair grows in between her legs. That might make a thread someday.....Hair on the model's neck compared to the hair in between the models legs. Hair to Stay and Rodney Moore might have pics that show both.
On a summer day when a woman has her hair in a pony tail and you see hair spillage on her lower neck and then she gets caught in a heavy rain, her hair spillage on her neck will curl up like her pussy hair when it is wet.
That hair spillage on her neck will be an indicator as to how much hair spillage she will have on her inner thighs.
