A Clinical Trial to Evaluate the Effects of a Conditioning Mask on Hair Health, Breakage, Hydration, and Detangling

This study evaluates the effects of the Bounce Curl conditioning mask on hair health, breakage, hydration, and detangling. The trial is conducted as a single-arm, unblinded, virtual study in which all 40 enrolled participants use the test product twice per week over a one-week period.

Participants complete self-reported questionnaires at Baseline, after the first use, and at the end of Week 1. The primary objective is to examine the product's effects on hair health as reported by participants, while secondary objectives assess perceived changes in hair quality, hydration, breakage, detangling, softness, and frizz.
