Najjar is an artist known for her haunting portraits and her delicate gold and silver leaf works. She draws inspiration from the works of Gustav Klimt and Byzantine religious iconography of the fifteenth and sixteenth centuries, which can be seen in her use of gold and silver leaf. The female form is often portrayed as something that is simultaneously fragile, spun as delicately as gossamer, and robust, able to withstand unspeakable hardships. With a muted, autumnal color scheme, Najjar’s works focus on women, children and the emotional effect of their environments on them both internally and externally.

Najjar graduated with a bachelor’s degree in Fine Arts from An-Najah University in Nablus, Palestine in 2005 and taught there for two years following her graduation. She also taught and worked as head of the Art Department in Al-Isra University, Amman. Her first solo exhibition was titled Monotone and was held at Fann-A-Porter Gallery in Dubai. She has participated in several exhibitions including Najjars at Wadi Finan Gallery in Amman in collaboration with her brother the Artist Omar Najjar, Untitled exhibition at Zara Gallery in Amman, 7+7 and Job Title exhibitions in Amman as well as other group exhibitions in Bahrain, Abu Dhabi, Lebanon, Egypt, Poland, Dubai and Palestine.

In 2006 Najjar painted icons for the walls and domes of Saint Maria Cathedral in Nablus. She has collaborated with various NGOs in Jordan and Palestine including Save the Children and the Palestinian Medical Relief Society.
