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.
How ever long it takes for the hair to grow, it takes about 12 to 18 months for the hair to grow in fully. Sometimes at 12 months as the hair is cycling into what is known as asynchrony (to be explained), the hair thickness can actually dip a little towards a year.
