Abstract
We investigate distributions of matter fields outside spherically symmetric ultra-compact objects in the asymptotically flat background. Based on the dominant energy condition and the non-negative trace condition, we analytically find a no long hair behavior, which states that the effective radius of matter field hairs cannot extend beyond the outermost null circular orbit.
