History

PLU Laboratories is an American direct-to-consumer skincare and haircare company specializing in copper peptide formulations. The company was started by brothers who faced a problem with existing products; one had tried minoxidil and dealt with irritation, another researched copper peptides and found sourcing them meant gambling on overseas suppliers with concentrations that rarely matched the label. They built the product they wished they could have bought.
