Formulation and test activities of hair tonic with a combination of the aqueous extracts of aloe vera ( Aloe vera L.) and licorice (Glycyrrhiza glabra L.)

Abstract

Aloe vera contains lignin, folic acid, vitamin A, and 20 types of amino acids, while Glycyrrhiza glabra L. contains glycyrrhizin, steroids, and beta-glycyrrhetinic acid that benefit for hair health. This research aimed to produce hair tonic with the best activity from the combination of aloe vera and licorice extract. The phytochemicals in the aqueous extract of licorice and Aloe vera were screened. The hair tonic was then prepared with 3 formulas using 7.5% Aloe vera extract and 2.5% licorice extract, as well as 96% ethanol with varying percentages, namely 5, 10, and 15%. Afterward, the formulas were tested for their activity as hair fertilizer on 4 white male rabbits for 28 days. The evaluation of hair tonic preparation included organoleptic observation, pH, specific weight, viscosity, and hedonic tests. It measured hair growth rate, the acceleration of hair growth, and hair weight. The results showed that hair tonic containing a mixture of 7.5% of Aloe vera extract, 2.5% of licorice extract, and 96% ethanol with different percentages (i.e., 5, 10, and 15%) created a good hair fertilizer. Hair tonic prepared with 15% of 96% ethanol exhibited an optimum activity. It was characterized by brown color, distinctive odor, homogeneity, a specific weight of 1.0577 g/mL, a viscosity of 2.8479 cP to distilled water, and pH 5.5. Its effectiveness as hair fertilizer was evidenced by a hair growth rate of 2.6617 cm in 28 days, a hair growth acceleration of 0.1635 cm/day, and a hair weight of 0.1854 gram in 28 days.

Formulation and Stability Tests of Hair Tonic from Oil Palm (Elaeis guineensis Jacq.) Leaves Extract and Effectiveness in Protecting Hair

“…In making hair tonic preparations, it is necessary to prepare the tools and materials that will be needed during the formulation process, all ingredients are weighed according to the calculation results, the hair tonic formula using [4] with slight modification can be seen in Table 1. Hair tonic preparation were made in concentration of 0 ppm, 12,5 ppm, 25 ppm, 50 ppm, 100 ppm, and 200 ppm in amount of 100 mL.…”

“…The hair tonic formula used in the study refers to the research results of [15] with the evaluation results and physical stability of stable hair tonic preparations. The selected additional ingredients in the manufacture of hair tonic have a function, namely 96% ethanol as a solvent and penetration enhancer with a concentration of use in cosmetic preparations not more than 30%, propylene glycol is used to dissolve extracts, humectants and affect the viscosity of preparations with a concentration of 5-80 %, menthol as a penetration enhancer in the skin and a cooling sensation with a concentration of 0.05-10% for topical preparations, phenoxyethanol as a preservative with a concentration for use in cosmetic preparations of 0.5-1% and distilled water as a solvent [16].…”

“…The scorching sun, dust, and pollution make hair limp and brittle more easily. So that people live in tropical areas really need hair care to overcome these problems [4].…”
