> if european whiteness is a product of sexual selection of rare blondes
It isn't. European whiteness (of skin) is a product of women being more heavily selected than men, since paleness of skin is a sex characteristic of females. (For example, african boys are born light, and darken over time. African girls are born light, darken until puberty, and then lighten.)
European variation in hair and eye color (but not skin color) is a color polymorphism typical of sexual selection. On this theory, 85% of adults sharing the identical hair color is unexpected.

Here are some of my own thoughts on your question (I claim no qualification at all to pontificate here):
- What size are these "some parts of Sweden and Finland"? The smaller they are, the less interesting it is that they might appear uniform.
- Do 85% of adults share the identical hair color, or is variation being binned into the category "blonde"? Compare the internal variation of african or chinese hair color.
