A fissure is a long, narrow crack opening along the surface of Earth. The term is derived from the Latin word fissura, which means cleft or crack. Fissures emerge in Earths crust, on ice sheets and glaciers, and on volcanoes. Ground fissure
A ground fissure, also called an earth fissure, is a long, narrow crack or linear opening in the Earths crust. Ground fissures can form naturally, such as from tectonic faulting and earthquakes, or as a consequence of human activity, such as oil mining and groundwater pumping. Once formed, ground fissures can be extended and eroded by torrential rain. They can be hazardous to people and livestock living on the affected surfaces and damaging to property and infrastructure, such as roads, underground pipes, canals, and dams.In circumstances where there is the extensive withdrawal of groundwater, the earth above the water table can subside causing fissures to form at the surface. This typically occurs at the floor of arid valleys having rock formations and compacted soils with a high percentage of fine-grained material. Crevasse
A crevasse, also called an ice fissure, is a deep linear crack in an ice sheet or glacier resulting from  the opposing force produced by their movement at different rates of speed. The force builds until their associated shear stress is sufficient to break the ice along the faces. The breakage often forms vertical or near-vertical walls, which can melt and create seracs, arches, and other ice formations.
It is not recommended to be used when cancer is present in the skin of the scalp or for lymphoma or leukemia. There are generally only minor side effects from scalp cooling given during chemotherapy. Embracing baldness
Instead of attempting to conceal their hair loss, some people embrace it by either doing nothing about it or sporting a shaved head. The general public became more accepting of men with shaved heads in the early 1950s, when Russian-American actor Yul Brynner began sporting the look; the resulting phenomenon inspired many of his male fans to shave their heads. Male celebrities then continued to bring mainstream popularity to shaved heads, including athletes such as Michael Jordan and Zinedine Zidane and actors such as Dwayne Johnson, Ben Kingsley, and Jason Statham. Baldness in females, however, is still viewed as less "normal" in various parts of the world. Alternative medicine
Dietary supplements are not typically recommended. There is only one small trial of saw palmetto which shows tentative benefit in those with  mild to moderate androgenetic alopecia. There is no evidence for biotin. Evidence for most other alternative medicine remedies is also insufficient. There was no good evidence for ginkgo, aloe vera, ginseng, bergamot, hibiscus, or sophora as of 2011.Many people use unproven treatments to treat hair loss. Egg oil, in Indian, Japanese, Unani (Roghan Baiza Murgh) and Chinese traditional medicine, was traditionally used as a treatment for hair loss. Research
Research is looking into connections between hair loss and other health issues.
