Cosmetic skin and hair care compositions for enhancing the growth and appearance of mammalian hair in an individual are provided, which compositions comprise a dose of an L-type calcium channel blocker effective to promote anagen phase of the hair cycle. As shown herein, anagen phase promotion can result in more rapid hair growth.

Compositions for increasing hair growth

Compositions and methods for light controlled protein-protein interactions in a living cell. Two interacting PICL (protein interaction controlled by light) polypeptides are provided. The first polypeptide comprises an LOV (Light, Oxygen or Voltage) domain, which domain is a light sensor that uses flavin mononucleotide (FMN) as a chromophore. The second polypeptide, specifically interacts with the L polypeptide upon light activation of the LOV domain. One or both of the polypeptides are fused to a cellular protein of interest. Upon exposure to light, a targeted interaction between cellular proteins occurs. The ability to regulate protein-protein interactions with subcellular resolution using light is useful for controlling biochemical processes such transcription, receptor activation, protein degradation, synapse formation, etc. in cells and animals.
