Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

The site balances substance and fluff with a heavy reliance on a single active ingredient, Ketoconazole 1 percent. While it provides specific metrics like 10X more effective and 2-3 times more hair loss, these are often buried under repetitive headings like CLINICALLY PROVEN and CLEAN fresh scent. The body substance is hampered by significant concept repetition, restating the antifungal mechanism across all four analyzed pages with minimal new technical detail.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.
