Which outcome arises when disulfide bonds are disrupted in keratin proteins during hair perming process?

💡 Explanation

When disulfide bonds are broken through reduction during hair perming, rearrangements of the keratin protein chains occur leading to new cross-links that fix the hair shape because the chemical bonds dictating original formation are forcibly changed. Therefore, a permanent change of shape results, as opposed to strength, resistance, or water absorption, which are contingent on intact disulfide bonds.
