The present invention is drawn to adhesive solidifying formulations, methods of drug delivery, and solidified layers for topical delivery of drugs for treating alopecia. The formulation can include a drug for treating alopecia, a solvent vehicle, and a solidifying agent. The solvent vehicle can include a volatile solvent system having one or more volatile solvent, and a non-volatile solvent system having one or more non-volatile solvent which is capable of facilitating the delivery of the drug at therapeutically effective rates over a sustained period of time. The formulation can have a viscosity suitable for application to a skin surface as a layer prior to evaporation of the volatile solvents system. When applied to the skin, the formulation can form a solidified layer after at least a portion of the volatile solvent system is evaporated.
