Effect of Natural Acids on Structure of 1a Black Hair

Overview

It has recently become a common practice to alter the color of human hair through different cosmetic procedures. This, however, can be very damaging to the health of the hair follicles due to the many chemicals that go into these commercial products. As a result, the following question has arisen: How does adding natural acids to a strand of 1A black hair cause damage compared to chemical hair dye? In the hopes of providing an answer, this study experimented with natural ingredients, namely lemon juice and yogurt. The goal was to support the hypothesis that naturally sourced ingredients can achieve the same results as hair bleach while preserving hair's health. Different ratios of these ingredients were combined, applied to the four experimental groups, and kept on the hair for 3 hours to determine their effect. This study supported the previously stated hypothesis since results showed that hair was noticeably less damaged while still showing signs of lightening in color. The p-values of all experimental groups indicated that the hair lightened significantly, and two groups showed a smaller amount of damage in the hair. These experimentations supported the idea that natural ingredients could be used as substitutes for commercial hair-lightening products.
