Scalp surface lipid (SSL) is one of the important parameters for the physiological study of human scalp. We investigated the refatting rate on the four sites (vertical, frontal, occipital, temporal) of the head in different seasons, before and 2, 24, 48hrs after shampooing. Forty normal females aged between 27 and 52 years were employed as subjects, and the Lipid Meter (Ricoh Co.) was used for measuring SSL. Following results were obtained:
1. SSL began to be secreted immediately after shampooing and returned to the level of before shampooing in 24hrs.
2. The refatting rate on the scalp depends on sites of the head: SSL was produced in the vertical and frontal sites almost from twice to thrice as much as that of the occipital and temporal ones.
3. No seasonal difference was observed in the reffatting rate on each of the three sites of the head except frontal site.
