    TLDR The gel and tonic were not stable.
    The study investigated the physical and chemical stability of hair growth-promoting gel and tonic formulations containing ethanol extract of red grape seeds (Vitis vinifera L). Stability testing was conducted in a climatic chamber at 50˚C and 75% relative humidity for 30 days. The physical stability parameters evaluated included organoleptic properties, homogeneity, specific gravity, viscosity, and flow properties, while the chemical stability was assessed by measuring the pH. The results indicated that both the gel and tonic formulations were not stable under the tested conditions.
