CSEF · 2006 Pharmacology/ Toxicology

Jeanna M. Peirano · Redwood High School, Larkspur

Overview

Objectives/Goals The purpose was to find out what hair reparative treatment strengthened hair exposed to various amounts of chlorine the most. Methods/Materials The materials were 150 strands of hair, chlorine, electronic balance, rice, pan, glass cups, water, stickers, saran wrap, and a box. Results The results followed a trend of that the more chlorine the hair was exposed to, the weaker it became. Using no hair treatment strengthened the hair more than using one. Conclusions/Discussion Hair reparative treatments do not strengthen hair. Chlorine weakens hair, and in larger amounts it bleaches it.
