research Test activity of hair tonic of ethyl acetate fraction from the ethanol extract of meniran (Phyllanthus niruri L.) as hair grower to male white rat (Rattus norvegicus) wistar strain
The hair tonic with menthol grew longer hair, but both formulas had similar overall hair growth.
research Isolation and characterization of recombinant murine Wnt3a
Scientists successfully purified a protein called Wnt3a, which is involved in processes like hair growth, but the overall yield was low, suggesting more work is needed to improve this.
research Validation of a skin and coat scoring protocol in dogs
The protocol is easy to use, but reliable results need the same person to assess each time.
