* Permanent Absorption: When Rogue absorbed Carol Danvers' powers in a prolonged and uncontrolled encounter, it wasn't a temporary power theft. She essentially copied Danvers' powerset and merged her consciousness to some extent.
* Psychological and Physiological Stress: This absorption was incredibly traumatic for both Rogue and Carol Danvers. Rogue struggled to control the immense power and was deeply affected by Danvers' memories and personality. This intense stress manifested physically, causing her hair to develop the white streaks.
* Symbolic Representation: The white streaks serve as a visual reminder of the profound and permanent consequences of her actions and the burden she carries. They symbolize the loss of her original self and the integration of Carol Danvers' essence into her being.
* Varying Explanations: Different comic runs and adaptations have offered slightly varying degrees of emphasis on the exact cause, but the core reason remains consistent: Rogue's white streaks are a direct result of the permanent absorption of Carol Danvers' powers and the associated trauma.
