~~~~~~~~~~~~~~~~~~~~~~~~~~~
One possible solution is this:
One with brown hair, another is blonde and the third is brunette.
Three friends, in all.
And if you add even one more person with the hair color from this list {brown, blonde, brunette}, the condition will be violate.
Hence, the found solution is unique.
There is NO other solutions.
