The Face Behind The Brand

Born and raised in Brooklyn, NY with proud Jamaican roots, Alisha Thorbourne is a force of nature. Grounded in her heritage and fueled by resilience, she’s built her life and career around uplifting others. As a social worker, she advocates fiercely for underserved communities, embodying the resourcefulness and warmth of her cultural upbringing.
But Alisha’s path wasn’t without challenges. Years of battling debilitating migraines and other health challenges pushed her to redefine her lifestyle—nourishing her mind, body, and spirit. This journey sparked a revelation: the products she used on her hair were doing more harm than good. Determined to find better solutions, Alisha founded Coiled by Definition, a natural hair care brand inspired by self-care, cultural pride, and the power of herbs.
Every formula is a labor of love, created in collaboration with expert chemists to ensure the highest quality. Alisha’s guiding principle? Only the purest, safest ingredients make the cut—because what touches your hair and skin should honor you.
Coiled by Definition isn’t just a brand; it’s Alisha's love letter to coils, kinks, and the radiant beauty of diversity. Her mission: to inspire confidence, celebrate culture, and transform the hair care industry—one lush coil at a time.
