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.
The growth phase is called anagen. How long anagen lasts is determined genetically, and varies between the sexes and from one person to another. It is the length of this time that determines how long the hair will grow. For head hair, the anagen phase can last from three to as much as seven years. Fun fact/myth buster: It is not true that cutting your hair makes it grow faster or thicker.
