Ok read the whole thread. no one pointed out that a helmut pushed down over long bangs in front would put your hair right in your eyes.Also a beard would be a pain if you had a stap on the helm.
I think the whole REH animal like description thing covers the "black mane"
He was always using it to draw out a mental image of power.
His hair is visible even under a helmet."Under the horned helmet a square cut black mane contrasted with smoldering blue eyes.?
-Queen of the Black Coast
It is probable that he has longer bangs based on these quotes."From under a mop of unruly black hair smoldered a pair of dangerous blue eyes.?
? The God in the Bowl"a shock of tousled black hair crowned his broad forehead."
-The Tower of the Elephant"Under his tangled black man his blue eyes blazed with unquenchable savagery.?
? Rogues in the House"A low broad forehead was topped by a square-cut tousled mane as black as a raven?s wing.?
?Black Colossus"The perspiration of agony beaded his face and his mighty breast, but from under the tangled black mane that fell over his low, broad forehead, his blue eyes blazed with an unquenchable fire.?
? A Witch Shall Be Born?The Cimmerian growled wordlessly, glaring truculently at the surrounding waste, with outthrust jaw, and blue eyes smoldering savagely from under his black tousled mane, as if the desert was a tangible enemy.?
? Xuthal of the Dusk?So formidable was his appearance, naked but for short leather breeks and sleeveless shirt, open to reveal his great, hairy chest, with his huge limbs and his blue eyes blazing under his tangled black mane, that the squire shrank back, more afraid of his king than of the whole Nemedian host.?
? The Hour of the Dragon
I think that his hair is probably a good deal shorter than how it is normally depicted other than when his hair grew long during his wanderings in The Hour of the Dragon
. I would say the length of the back is between the jawline and to the tops of his shoulders, but not down his back. I think the multiple references to his mane are not just a nod to his animalistic nature but a description of a large volume of hair appearing like a lion's mane."His heavy brown arms were folded, his black hair, grown long in his wanderings, blew in the wind. A wilder and more
barbaric figure never trod the bridge of a ship, and in this ferocious corsair few of the courtiers of Aquilonia would have recognized their king."
- The Hour of the Dragon?It was there, in the corner,? muttered the king, tossing his lion-maned head from side to side in his efforts to rise."
