How it started

This company was founded to make a difference in the industry and is committed to serving our customers with honesty, authenticity, and inclusivity.

We’re starting to become a little ingredient-obsessed when it comes to the hair loss shampoo trend. 

For most products on the market, it’s not just the ingredients that produce results, 

but the technology of the formula infused into the product. 

 Have something with an ingredient that is beneficial to hair, even if it’s a drop or two? 

Send it our way, as we are all about trying something new.
