tautomers thereof and pharmacologically acceptable acid addition salts thereof; and ii. an C 8 -C 24 alcohol ester of a carboxylic acid; b. a viscosity modifying agent comprising a nonionic hydroxypropylmethyl cellulose and a carboxymethyl cellulose having: i.) a carboxymethyl degree of substitution of from 0.4 to 1.5, wherein the degree of substitution is the average number of ionizable carboxymethyl ether groups per repeating anhydroglucose chain unit of the cellulose molecule; ii.) an average degree of polymerization of from about 2000 to about 4000; and iii) a weight average molecular weight of from about 600,000 to about 800,000 at a ratio of the nonionic hydroxypropylmethyl cellulose to the carboxymethyl cellulose of greater than about 1:1; and c. a pharmaceutically acceptable topical carrier comprising, one or more solubilizer, one or more solubilizing acid or mixtures thereof; wherein the total concentration of the nonionic hydroxypropylmethyl cellulose and the carboxymethyl cellulose is from about 0.5% to about 3% by weight of the total composition and wherein the liquid vesicles are suspended within the pharmaceutically acceptable topical carrier. a. liquid vesicles comprising: i. one or more of a hair growth or hair regrowth compound represented by formulas I or II: and mixtures thereof, wherein R 1 is hydrogen or -N(R 3)(R 4), each R 3 and R 4 individually is selected from the group consisting of hydrogen, lower alkyl, lower alkenyl, lower aralkyl, and lower cycloalkyl, and taken together R 3 and R 4 may be a heterocyclic moiety selected from the group consisting of aziridinyl, azetidinyl, pyrrolidinyl, piperidino, hexahydroazepinyl, heptamethylenimino, octamethylenimino, morpholino, and 4-lower-alkylpiperazinyl, each of said heterocyclic moieties having attached as substituents on the carbon atoms 0 to 3 lower alkyl groups, hydroxy or alkoxy, and wherein R 2 is selected from the group consisting of hydrogen, lower alkyl, lower alkenyl, lower alkoxyalkyl, lower cycloalkyl, lower aryl, lower aralkyl, lower alkaryl, lower alkaralkyl, lower alkoxyaralkyl, and lower haloaralkyl;
