Parsley (Petroselinum Crispum) Fraction-Loaded Nanoemulsion Using Coconut Oil: A Novel Approach for Hair Growth Promotion

This study explores the hair growth-promoting potential of a parsley-derived n-hexane fraction formulated into a coconut oil-based nanoemulsion. The nanoemulsion demonstrated moderate antioxidant activity, although this decreased due to surfactant interference. Characterization showed a droplet size of 12.1 nm, low polydispersity index, and stable zeta potential, indicating uniformity and stability. In a hair growth study, the 3% parsley nanoemulsion showed significant regrowth comparable to 3% minoxidil, with visible results by day 10 and near-complete coverage by day 17. These results suggest that the parsley-coconut oil nanoemulsion is a promising and effective topical formulation for hair growth.
