According to the previous research, essential oil from Cymbopogon citratus Stapf (Lemongrass) was able to inhibit
Malassezia furfur and was formulated as hair tonic. However, sensory efficiency of lemongrass oil hair products has not been
reported. This research aimed to formulate and evaluate sensory efficiency of lemongrass oil hair rinse cream added with
fixatives. It was found that the chief chemical constituents of lemongrass oil determined by GC-MS were cis-citral and
trans-citral. In addition, total content of both citral isomers in our lemongrass oil was 76.56 percent which met Thai Industrial
Standard. It was shown that all formulae of lemongrass oil hair rinse cream added with fixatives possessed satisfy physical
stability. Sensory efficiency evaluation of all hair rinse cream formulae added with fixatives was performed by rinsing hair lock
and rating by 30 evaluators. The results revealed that hair shining, styling, hair softness, ability to reduce hair loss, weighting,
odor after 2-days rinsing and odor after freshly rinsing of hair lock rinsed with all formulae were not statistical difference.
Unless the hair rinse cream using natural leech lime oil as fixative which showed a higher hair shining than hair rinse cream
without fixative with statistical difference (P<0.05). It was suggested that leech lime oil possessed organic acid namely citric
acid that could increase hair shining and hair plenty. Lemongrass oil hair rinse cream using leech lime oil as fixative possessed
physical stability, satisfy sensory efficiency and showed ability for further commercial development.
