Haageocereus albispinus grows columnar with three to ten shoots branching from the base and reaches heights of up to 2 meters. The slender dark green shoots, densely covered by thorns and hairs, have a diameter of up to 6 centimeters. There are 25 to 26 low ribs . From the 6 to 7 millimeters apart, white felted areoles arise 35 to 40 white, twisted hairs up to 1 centimeter in length. The occasional single central spine , mostly missing, is piercing needle-like and up to 1.5 centimeters long. The approximately 25 radial spines, which are initially light yellow, later become silver-white and are up to 1.3 centimeters in length.
The narrow, funnel-shaped, greenish-white to green flowers reach a diameter of up to 4.5 centimeters. The ellipsoid, pink fruits have a diameter of up to 3.5 centimeters and are covered with long white hair.
