Hardly.

The House of Hador, its related ancestors of the Northmen, the Northmen, some of the Numenoreans, and the descendents of the Northmen (aka the Rohirrim) are all said to have been "golden-haired".

It is the Elves that are rare as blond/blondes.

Of the Vanyar, the Noldor, and the Teleri, only the Vanyar are said to have been predominantly blond. The Noldor and the Teleri (including the branches of Sindar, Nandor, Silvan, Avari), who are the Elves seen in Middle-earth, are described as mainly dark-haired. Only a smattering of silver-heads, copper-tops, and golden-tresses among them.
