5 /5 Rusty Haynes: Jonathan is the best. After living my entire life with short hair, I decided to finally grow my hair out in my late 30s. As any long-haired man knows, if you want to do it right, there is a method to growing out and maintaining your mane, which is both scientific and artistic. Jonathan guided me through the entire journey, including tips and tricks of how to navigate those awkward phases along the way.
