Literature Review: Hair Growth Cosmeceutical Preparations from Various Nusantara Herbs

The document reviews various herbal cosmeceutical preparations for hair growth and identifies a hair tonic made from kale leaves (Ipomoea aquatica Forsk.) at a 5% concentration as the most effective. This hair tonic showed an average increase in hair length of 2.785 ± 0.021 cm and hair weight of 0.767 ± 0.057 mg/cm2 over a period of 21 days. The pharmaceutical evaluation of the kale leaf hair tonic confirmed that it meets the established SNI (Indonesian National Standard) requirements for hair tonic preparations. The study is based on a systematic literature review, but the document does not specify the number of subjects involved in the in vivo evaluation.
