Cardi B/Instagram screenshot/@iamcardib Cardi B's new haircare brand, Grow Good , sold out in the first 24 hours of its release. The rapper's vegan haircare brand promises effective results, with Cardi confirming that she tested the products on her own hair before launching them. After struggling to care for her natural hair, the "Bodak Yellow" singer began her hair-growth journey in 2016 and has since managed to grow her hair down to her lower back. Photo/Instagram@growgoodb
