After a relaxer treatment, the hair may still have some of the chemical used in the relaxer left in it. This can be damaging to the hair if not properly neutralized. A neutralizing shampoo works to remove any remaining product and balance the pH levels of the hair, preventing further damage. Although conditioning is important after a relaxer treatment to restore moisture, the primary purpose of the neutralizing shampoo is to neutralize the chemical and promote healthy hair. Choosing option A or D may lead to further damage as they do not address the need for neutralization. Option C may be a good choice for regularly oily hair, but is not the primary purpose of a neutralizing shampoo.
