The amount an average American woman spends on hair care in her lifetime. Your hairID helps you spend wisely on the right products for your hair.


The number of shampoo bottles that end up in landfills each year in America. How much hair care clutter is sitting in your shower right now?


The number of daily decisions the average person makes. Let hairID help reduce your decision fatigue by making hair care decisions easier and more effective.
