Rusticbeauty is one of my FAVORITE youtube hair ladies, and I've been following her since my early natural days. She's achieved long, healthy natural via twisting and certainly has a hair care routine that works well for her. In her earlier videos, she was big on using shea butter, Infusium 23, Organix, and coconut oil. I share her channel with you for inspiration.

DISCLAIMER: Other people's hair care routine may or may not work for you. Rather, use the suggested hair care routine as guidance and tweak for your hair.
