Or the meaning of the sentence since it was taken out of context.
I'm not sure that additional context is needed to understand what's going on. She's smelling his hair and describing her impression of its odor.
But if it helps, here's the context from Chapter Seven of Amélie:
That night on the island, she'd rolled over against Gérard. She smelled the salt on his skin, the fading aroma of her own scents that followed their vigorous lovemaking. His skin burned, it seemed to her, when she rested the pads of her fingers on his neck to feel his steady pulse. His hair, unkempt and uncut since their last port, was redolent of salt and sweat. She felt the stubble on his cheek. A visit to the barber at their next port would be in order, she thought.
ETA: I've enjoyed the comments and appreciate them. I'm keeping "redolent." After all, the reader is given a purple prose alert at the beginning. My only worry is that it probably isn't purple enough, although I do like "manchowder" when it appears here and there.
