Abstract This study showed that hydrogenated palm oil was an effective conditioning agent for repair of damaged hair because it inhibits water-induced swelling of damaged hair. To understand the functional mechanism of hydrogenated palm oil, we conducted TOF-SIMS analysis of the penetration of this oil into damaged hair. TOF-SIMS analysis revealed that tripalmitin, a constituent of hydrogenated palm oil, penetrated into the cuticle and the outer cortex of damaged hair. This is considered as the mechanism responsible for inhibition of hair swelling by hydrogenated palm oil.
