A Comprehensive Review of Oryza Sativa and Psidium Guajava Leaf Extracts in Herbal Hair Serum for Improved Hair Health

This study reviews the development and evaluation of a herbal hair serum using extracts from Oryza sativa (rice) and Psidium guajava (guava) leaves, aimed at improving hair health. Oryza sativa is noted for its bioactive compounds like amino acids, antioxidants, and vitamins that strengthen hair follicles and promote growth. Psidium guajava leaves contain flavonoids, tannins, and vitamins with antimicrobial and anti-inflammatory properties, beneficial for reducing dandruff and enhancing scalp health. Three serum formulations were tested for phytochemical content, organoleptic properties, pH, viscosity, and microbial stability, highlighting their potential as natural hair care solutions.
