1. A dissolvable solid structure, wherein the dissolvable solid structure is formed by a homogeneous mixture comprising, by weight of the structure:
polymeric structurants consisting of:
from about 1% to about 10% of one or more first polymeric structurants wherein the structurants comprise a molecular weight of from about 1,500,000 g/mol to about 3,500,000 g/mol;
from about 10% to about 20% of or more second polymeric structurants wherein the structurants comprise a molecular weight of from about 65,000 g/mol to about 396,000 g/mol;
wherein the ratio of the first polymeric structurants to the second polymeric structurants is less than 1:1;
wherein the first and second polymeric structurants are polyvinylpyrrolidone, its copolymer, or a mixture thereof;
from about 10 wt % to about 85 wt % of one or more high melting point fatty material comprising a carbon chain length C12-C22 or mixtures thereof and a melting point above 25° C.; and
from about 1 wt % to about 60 wt % of a cationic surfactant;
wherein the combined average molecular weight of the first and second polymeric structurants is from about 350,000 g/mol to about 1,000,000 g/mol;
wherein the dissolvable structure is a hair conditioner.
