How can hydroxide ions left in the hair after a relaxer be neutralized?

The process of neutralizing hydroxide ions after a relaxer treatment involves restoring the hair's pH balance. Hydroxide ions can cause the hair to become more alkaline, leading to damage if not adequately neutralized. Using an acid-balanced shampoo is effective because it helps to lower the pH level back towards a neutral state. Acid-balanced shampoos contain ingredients that can help counteract the alkaline effects of hydroxide ions, thus restoring the hair’s natural acidity and improving its overall condition.

Other options may not effectively address the residual hydroxide ions. For instance, while clarifying shampoos are effective for removing buildup on the hair, they may not specifically neutralize hydroxide ions. Neutralizing conditioners are typically used in conjunction with relaxer treatments but do not specifically target the hydroxide ions left in the hair after the process. Detergent soaps, while they may clean hair, are not formulated to balance pH and may be too harsh for the hair, potentially leading to further damage.
