Strands uses science to develop custom shampoos and conditioners specifically for your hair. When your hair sample arrives at the state-of-the-art laboratory in Los Angeles, Strands's scientists will clean up any product, environmental or chemical residues in your sample. Their team will use advanced microscopy and spectrophotometry to analyze the texture of your hair, surface proteins and cuticle to create your test report. Their chemists review your reports and design your custom formulations with the highest quality ingredients and your premium perfumes. They print your details on your bottle and deliver them to your door. Each bottle is handmade with your name and details of your personal ingredients.
