The effects of agents on the length of the stages of the hair growth cycle can be assessed, with or without a cytotoxic insult. The hair growth cycle can be synchronised and the effects on the rate of hair regrowth can be quantified following epilation or a cytotoxic insult.
Effects on proliferation, apoptosis and related target pathways can be measured by protein or gene expression, in vivo or using plucked scalp hair.
