Abstract

Hair loss is a common condition affecting many individuals, particularly teenagers and women who wear the hijab. Aloe vera contains various bioactive compounds, including vitamins, proteolytic enzymes, and amino acids, which are known to nourish the scalp and stimulate hair growth. This study aims to evaluate the effectiveness of Aloe vera extract in different types of hair care formulations, such as shampoos, hair tonics, serums, and pomades, for treating hair loss. A qualitative descriptive literature review was conducted by analyzing 30 relevant national and international scientific articles published between 2016 and 2025. The findings indicate that Aloe vera has the potential to reduce hair loss, promote hair growth, and support scalp health. Furthermore, the combination of Aloe vera with other herbal ingredients, such as candlenut, celery, and lime, may enhance its efficacy. Products based on Aloe vera are also reported to have good physical stability, be safe for use, and be compatible with various scalp types. The study concludes that Aloe vera is a promising natural ingredient for the development of safe, effective, and sustainable herbal hair care products.

Abstract

The premature aging process is usually characterized by visible wrinkles or wrinkles on the face, dry and rough skin, age spots and decreased skin elasticity. Noni leaves (Morinda citrifolia L.) are one type of herbal plant that can potentially act as an antioxidant. The purpose of this study was to see Optimizing the Formulation of Lotion Preparations and Evaluating the Physical Properties of Lotion Preparations. Noni leaves were macerated with 96% ethanol solvent and then rotary with an evaporator. Hand and body lotion preparations were made by adding ethanol extract of noni leaves with several concentrations of 2.5% (F1), 5% (F2), and 7.5% (F3) to the base of hand and body lotion. As a blank (F0) the base of hand and body lotion without ethanol extract of noni leaves. Testing on the preparation was an evaluation of stability for 4 weeks at room temperature (odor, color, pH, emulsion type, homogeneity), irritation test and anti- aging skin activity test using a skin analyzer on hand skin. The parameters measured included water content, pore size, number of blemishes and number of wrinkles. Treatment was carried out using hand and body lotion every day for 4 weeks. Ethanol extract concentrations of 2.5%, 5% and 7.5% were homogeneous preparations with an oil-in-water emulsion type, pH 6.3-6.8, stable in storage for 4 weeks, and did not irritate the skin. Anti- aging skin hand and body lotion preparations containing ethanol extract of noni leaves can increase water content, reduce pore size, reduce the number of blemishes, reduce the number of wrinkles on the skin of the back of the hand and are stable in storage for 4 weeks. Hand and body lotion preparations with ethanol extract at a concentration of 7.5% had better skin antiaging activity compared to concentrations of 2.5%, 5% and blank.

Abstract

Red guava (Psidium guajava L.) contains natural antioxidants that help neutralize free radicals originating from radiation, pollution, and harmful chemicals. This study aimed to identify secondary metabolites and determine the IC₅₀ values of ethanol extract and various fractions of red guava peel and fruit. Four solvents were used ethanol extract, ethyl acetate fraction, n-hexane fraction, and water fraction. Each sample was tested at concentrations of 20, 40, 60, 80, and 100 ppm. Vitamin C, at concentrations of 2, 4, 6, 8 and 10 ppm, served as a positive control. Antioxidant activity was evaluated using the DPPH method with a UV-Vis spectrophotometer at a wavelength of 516 nm and an incubation time of 30 minutes. Phytochemical screening showed that all extracts contained alkaloids, flavonoids, and tannins. The IC₅₀ values obtained were: ethanol extract peel 62,4719 ppm, ethanol extract fruit 44,0035 ppm, ethyl acetate fraction peel 56,7955 ppm, ethyl acetate fraction fruit 46,4394 ppm, n-hexane fraction peel 113,9311 ppm, n-hexane fraction fruit 114,4767 ppm, water fraction peel 104,0284 ppm, and water fraction fruit 76,5801 ppm.
