Our previous study showed that after shampooing, scalp surface lipid (SSL) returned to the before level in 24hrs. In this communication, we investigated the relation between the refatting rate on the scalp 24hrs after shampooing and those on the forehead and the cheek 2hrs after cleansing, in terms of age and skin type. Eighty-two normal females aged between 20 and 57 years were employed as subjects, and the Lipid Meter (Ricoh Co.) was used for measuring SSL as before.
Following results were obtained;
1. The vertical and frontal sites of the head showed almost the same refatting rate as the forehead, and the temporal site showed the refatting rate similar to the cheek.
2. SSL was significantly more produced in the group of females in their 20s and 30s than in the group in their 40s and 50s.
3. The refatting rate on the scalp was correlated with skin type: SSL was more produced in the oily and the oily with dry surface skin than in the normal and the dry skin.
4. It was suggested that the greasiness of one's scalp coud be better estimated from their skin type rather than their sense of greasiness of the scalp.
