TLDR Natural substance emulsions can effectively stimulate hair growth.
This study investigated the formulation of stable water-oil emulsions using natural substances for hair growth stimulation. Emulsions were prepared with extracts from Hibiscus rosa-sinensis L., Cannabis sativa L. seed oil, Ricinus communis L. oil, Olea europaea oil, and beeswax, and tested in vivo on Cavia porcellus L. for 28 days. The optimal emulsion, with a 4/6 water-oil ratio, a Hydrophilic/Lipophilic Balance (HLB) of 7, and an average globule size of 2.57 ± 1.91 μm, demonstrated good stability and capillary growth stimulation. The study concluded that emulsion stability is influenced by the hydrophilic/lipophilic balance, globule size uniformity, and hydrophilic/lipophilic ratio.
