I love wearing my diffuser scarves through the cold seasons. Having short hair, they not only warms my neck but accent my look and uplift me throughout the day. Each scarf has leather patch hand stitched on. This leather patch is decorative but also functions as a diffuser throughout the day. Place any pure therapeutic oil on the patch and create an amazing atmosphere anywhere you go. These scarves have become a topic of interest for many and have become very popular.
