Slip

Slip began with a problem its founder couldn't solve. In 2003, Fiona Stewart was prescribed acne medication that left her with extremely sensitive skin and thinning hair. Her dermatologist suggested sleeping on a silk pillowcase — but she couldn't find one worth buying, so she sourced the finest silk she could and wrapped it around her own pillow. The difference was immediate. In 2004 she launched Slip with her partner Justin Dubois, and today she remains co-founder and CEO.
