In one aspect, hair conditioning compositions are described herein. In some embodiments, a hair conditioning composition comprises a polymer or oligomer comprising (A) at least one hydrophilic block comprising an alkoxylated diol or amine-terminated derivative thereof and (B) at least one hydrophobic block comprising a condensation reaction product of (i) a dicarboxylic acid or dicarboxylic acid equivalent and (ii) a diamine, amino alcohol, diol, or combination thereof. The hydrophilic block (A) and the hydrophobic block (B) are bonded together through an amide or ester linkage. In addition, the polymer or oligomer comprises at least one amide moiety.
