However, we do know that The Starry Night was not Vincent van Gogh's first attempt at painting the night's sky, and by comparing the work to the earlier painting Starry Night Over the Rhone, one is able to make several inferences about how van Gogh felt by this point of his life.
Hair grows about 1/2 inch per month. If the rest of the scalp hair is long, it may take months or years before a shaved area grows sufficiently to match the rest of the hair. After shaving, the hair growing back may appear to be thicker and coarser, because the shaving process removes the natural thin ends of the hair.
Hair grows about .3 mm per day (about three tenths the thickness of a dime). Within a year, our scalp and beard can produce nearly five inches (13 cm). By comparison, the longest hairs on our arm have a growth cycle of less than two months. The growth cycle of scalp and beard hairs varies from individual to individual but can be several years. A Vietnamese man was reported to have the longest scalp hair, which measured over 20 ft. (6 m) long. According to a BBC News report in June 2004, he claimed not to have cut his hair in more than 30 years.
