Morphology
The meaning 'an iron that uses steam' is directly and transparently derived from combining 'steam' (vapor) with 'iron' (a handheld heated appliance); a B1 learner who knows both constituents can readily infer it's an iron that produces or uses steam for pressing or styling. This noun–noun composition is a straightforward, compositional compound found across languages, so the MWE is predictable from its parts.
Etymology
The noun steam iron for hair comes from the same image: picture a hot tool that sends a gentle mist of steam over hair to relax and smooth it. That's why a steam iron for hair means a tool that uses steam to 'straighten' hair and 'reduce damage'.
