 Item number SCP-337 Object Class Euclid Special Containment Procedures SCP-337 is to be kept within a steel reinforced 0.5 meter thick polished cement containment chamber at all times. Chamber walls must be inspected weekly for cracks and resealed as needed. Access will only be available via a two-stage vaulted steel door system with a seal tolerance not to exceed 100 micrometers. Anti-chamber between the doors is to be fitted with multiple remote operated liquid propellant flamethrowers. Both chambers are to be externally monitored with wireless security cameras. Damage or repositioning of cameras should be reported immediately. A self-contained water recycling shower system will be positioned at the far end of the internal chamber. The system's water supply and filters are to be changed on a monthly basis. Personnel assigned to SCP-337 must maintain all head and body hair at no longer than four centimeters and will submit to regular full-body inspection to ensure compliance. Any personnel entering the chamber must be escorted by two guards armed with portable flamethrowers. During Incident 337A, Class D personnel involved in testing must be strapped into a restraining gurney and sedated prior to entry. Once per week, one Class D personnel will be stripped of hair measuring longer than five centimeters using the Solomon technique. An attendant must immediately deliver the hair into the chamber and permit the object to feed. During this time, the attendant will sweep the floor clean of shedding using a standard broom and dustpan. Following Incident 337C, vacuum cleaners are not permitted for use within 15 meters of SCP-337 containment, unless specifically authorized. Description SCP-337 is a large conglomeration of human hair weighing approximately 60 kilograms at last measure. The object's shape and dimensions are tremendously variable. SCP-337 is fully animate, capable of a wide range of locomotion and can exert force in excess of 18 kilo newtons. It also seems to possess some low level of sentience, although attempts at communication have thus far met with limited success. The object is able to manipulate any hair directly connected to its central mass, with precision down to the individual strand. The method by which SCP-337 mobilizes its components is still under investigation. Analysis of filaments attached to the object has shown them to be identical to regular human hair, and strands that are periodically shed from the object are similarly normal, aside from being drained of pigmentation. Filaments display typical tensile strength and can be easily damaged by fire, blades, or consumer grade chemical clog remover. Although it displays no obvious sensory organs, SCP-337 is highly aware of its surroundings, and may even possess perceptive abilities exceeding those of humans. For the most part, these senses are tuned towards detecting and acquiring its principal form of sustenance. Fresh Human Hair When a human being with any hair measuring longer than 5 centimeters comes within approximately 30 meters of SCP-337, it enters what could be described as a predatory state, rapidly braiding together several dense tendrils of hair in the direction of its prey. The object's range of perception seems to be unhindered by the walls of its containment chamber. The object will then close in on its target at great speed, attempting to overtake an envelop it. When successful, SCP-337 restrains the subject's limbs, and begins to harvest all hair of sufficient length from the body. Hair is painlessly removed from the dermis at the base, root included. It is immediately incorporated into the object's mass via knotting or weaving. Patterns of bruising, bleeding, and sebaceous eruption on subjects following feedings suggest follicles are partially loosened from the inner sheath prior to extraction. This appears to sometimes accelerate hair regrowth, even in regions where it is typically stunted. To date, researchers have failed to replicate this effect artificially. While SCP-337 was found in a filthy state at time of recovery, it has since demonstrated a preference for cleanliness. Not long after initial containment, the object managed to escape its temporary enclosure through a narrow, 2 centimeters in diameter, wiring duct. It was discovered on site several hours later in the fourth floor women's washroom, where it emerged from a drain and consumed the hair of two showering researchers. A security team arrived shortly thereafter to find SCP-337 under a running shower tap, lathering itself with shampoo left behind by the women. Once containment was re-established, SCP-337's enclosure was fitted with its present bathing accommodations and a supply of hair-conditioning product. The object's rate of shedding has since decreased dramatically. Note, SCP-337 may seem to prefer live feedings, but it will still readily consume hair that has already been removed from a human host, provided the follicle is intact and the root has only been detached for a few minutes. We have established a means of accomplishing this extraction just as effectively, if not as painlessly, as the object's method. To limit risk of cross-contamination, Class D personnel should only be exposed to SCP-337 for approved testing purposes. Requests by personnel to be deliberately exposed for feeding are preemptively denied. Dr. B- Addendum SCP-337 has demonstrated the ability to grow well beyond its present mass through the accumulation of additional hair. It was discovered in the plumbing system of a large nursing home facility in B-Pennsylvania in 19- After Agent B-Pennsylvania noticed a story entitled, Sewer Snake Scalp Senior Citizens, in a local newspaper. A team was dispatched to investigate under the guise of a fumigation contracting company. After evacuating residents to another facility, agents cut off all water and sewage lines in the building, monitoring sink and shower drains for any sign of the object. When a portion of SCP-337 finally emerged, it attempted to couple with Agent B-Pennsylvania, only to be intercepted by his weapons bayonet. The tendril immediately retracted into the drain, after which time the object was not sighted again for more than 45 minutes. Coordinated deployment of chemical clog remover forced the object to exit through pipes in the facility's basement-level utility room, where several agents were on hand to apprehend it with portable flamethrowers. However, the agents were unprepared for the sheer size of the object, which quickly filled the lower level of the building. In the confusion, a sizeable portion of SCP-337 was ignited. The resulting blaze spread quickly throughout the facility. Most on the upper floors were able to flee the structure before it collapsed, but several agents did not escape in time. SCP-337 managed to extricate its remaining mass through the building's ventilation system, shedding burning components as it went. When it finally amassed in the facility's parking lot, it was estimated to be over 1 meter tall. Surviving members of the intervention team converged around the object, and successfully corralled it within the lot using flame propellant until support arrived. By the time SCP-337 was contained, it had lost more than 90% of its original mass. The fire and subsequent destruction of the nursing home was officially blamed on faulty wiring and damages were settled out of court. Displaced residents were transferred to a foundation-operated nursing facility, where amnesiacs were administered as required and data expunged without incident. SCP-337A Personnel Involved Dr. Solomon, D-28803 Date Undisclosed Description 10.26 AM Dr. Solomon and two guards enter anti-chamber of SCP-337 containment area, escorting D-28803 for scheduled testing. D-28803's hands and ankles are cuffed. He is moderately uncooperative, pleading not to be taken into the chamber. Rumors of a haircut monster are widespread among Class D personnel on site. 10.27 AM Dr. Solomon assures D-28803 that he is completely safe. She firmly reminds him that his cooperation is beneficial to them both. 10.29 AM All personnel enter in her chamber. SCP-337 has already extended several tendrils in direction of D-28803. D-28803 shouts multiple expletives, attempts to move toward exit, is restrained. 10.30 AM SCP-337 closes in on D-28803 D-28803 produces a small pair of shears that had previously been hidden in his waistband. D-28803 still cuffed, rests free from guards, and lunges at SCP-337, screaming. 10.30 AM D-28803 thrusts shears into SCP-337, managing to sever one of the object's tendrils. SCP-337 recoils as if in pain. 10.30 AM SCP-337 envelops D-28803. Dr. Solomon shouts something unintelligible to guards. A muffled cry is heard, followed by a wet-sounding thump. 10.31 AM Guards engage pilot lights of flamethrowers. SCP-337 retreats, disentangling itself from its host. D-28803 collapses to the ground. Body is hairless. Guards are buried up to the handle in the center of D-28803's forehead. Dense hair later discovered in nostrils, trachea, lungs. 10.32 AM Personnel exit containment chamber with corpse. Incident-337B Personnel involved. Dr. W. Heron referred to as Dr. R. Date undisclosed Description 4.57 PM Dr. R. and two guards enter anti-chamber of SCP-337 containment area. No D-class personnel are present. Object has refused feeding for two consecutive weeks. SCP-337's former handler, Dr. Solomon, was killed one month prior in an unrelated incident. 4.58 PM All personnel enter in her chamber. SCP-337 is spread out in a loose pile in center of room, braiding and unbraiding three tendrils. Dr. R approaches object. 4.59 PM Dr. R extends a large bottle of herbal shampoo toward SCP-337. SCP-337 stops braiding and retracts tendrils into itself. 5.00 PM A thick bulb-shaped extrusion of hair emerges at a 45-degree angle from the top of SCP-337. Hair contorts and intertwines on the bulb until detail begins to emerge. 5.01 PM Dr. R drops the bottle. SCP-337 has produced a crude but recognizable likeness of the late Dr. Solomon. 5.01 PM Dr. R stumbles back from the object. Both guards rush to support him. SCP-337 turns to follow Dr. R so that the head formation continues to face him. 5.02 PM The researcher appears severely distraught. She's gone, okay? She's gone! 5.02 PM Guards attempt to usher Dr. R to the exit. R grabs the handle portion of a guard's flamethrower and directs it at SCP-337. 5.02 PM Nearest guard punches Dr. R in the jaw. He crumples. Guards restrain the researcher and drag him to the exit. SCP-337 remains still, continuing to direct the head formation toward R. 5.03 PM All personnel exit containment chamber. The head retracts back into SCP-337, dissolving again into shapeless hair. After a moment, it retrieves the shampoo bottle from the floor and begins to lather itself. Note, this incident is troublesome for a number of reasons. There is no indication that Dr. R was in any way psychically affected by SCP-337, as some have proposed. A man had recently lost a close colleague, and psychiatric analysis after the incident revealed he was much more bereaved about it than he let on. Nevertheless, his reaction to the object's behavior seems illogically severe. It also squandered our first, and so far only, opportunity to engage in communication with the object. We are fortunate that SCP-337 returned to its former behavior patterns not long after the incident. For now, personnel assigned to SCP-337 should undergo periodic psychological evaluation until we know more. I also recommend rotating handlers for the object on a regular basis, so that no one becomes too attached. Dr. R. Lesson complete.
