Item #: SCP-491
Object Class: Euclid
Special Containment Procedures: SCP-491 is to be kept in a locked safe at all times, except when being used for testing. The combination is to be known only by staff of level 3 or higher. All tests should be taken in an empty room of at least 10x10x10m, with reinforced metal walls. Viewing areas are to be protected by military grade bullet-proof glass. Testing is to be performed on D-class personnel only. Researchers handling SCP-491 must take extra precautions to be sure that the substance does not come into contact with their skin. Any persons making skin contact with the substance outside of controlled testing environments are to be terminated immediately, and subsequently incinerated.
Description: SCP-491 appears to be a standard bottle of ███████ brand hair tonic. The item was recovered after reports were received of a house completely filled with hair. Upon arrival, agents found that the house in question was in fact filled with massive quantities of human hair, and bits of flesh and bone. SCP-491 was recovered near the center of the mass, and the house was incinerated as per protocol.
SCP-491 is filled with a yellow liquid. The liquid is noticeably darker and more viscous than that of other ███████ brand hair tonic bottles. The container is observed to slowly replenish itself after use; it is thought that the substance is self-replicating. Chemical tests found SCP-491 to be comprised of several 'unusual' proteins and enzymes, to which its effect is attributed.
When SCP-491 is applied, subjects complain of an 'itching' under the skin, which quickly becomes painful. This is followed by rapid hair growth. After 1 to 3 minutes, the subjects are completely torn apart from the inside by torrential amounts of internal hair growth. The hair continues to grow from the chunks of flesh, halting soon after. Testing confirms the hair to be that of the subjects.
