Specializing in hair care and body products for both adults and children, Knotty Girl was born out of Renée's desire to create gentle yet effective products inspired by her niece's sensitivity to many hair care products. With a vision to provide a "cradle to grave" solution, Renée crafted a line that catered to children's needs while offering benefits for adults as well.

The name "Knotty Girl" was a playful nod to Renée's niece, who was affectionately known for her mischievous nature, especially when it came to protesting the use of other body products. Signature products from the line included the Pink Princess Cotton Candy Shampoo, beloved for its irresistible scent, and the Drama Queen Sparkle lotion, infused with a delicious marshmallow aroma that leaves a subtle yet striking sheen on the skin.
