What it is
Folk hair-loss ingredient — efficacy unproven
How it affects the score
Strong marketing story, unproven efficacy. Adds no points, and appearing near the tail is flagged as an overclaim signal.
How to read it on the label
If a product headlines this ingredient, check its position and whether the amount (ppm) is disclosed. Tail position with no disclosure means trace amounts.
Ingredients are listed by descending concentration. Anything after the ~1% anchors (EDTA, hexanediol, preservatives) is effectively trace.
