Neonatal Occipital Alopecia (transient neonatal hair loss) is a common alopecia that develops in the occipital area in the first few months of life. It was previously wrongly attributed to friction of the head on the pillow. The fetus normally undergoes synchronous shedding of scalp hair in the fifth month of fetal life. The regrown hair enters into the telogen phase in a wave from front to back, starting approximately 12 weeks before term. Most hair roots will have entered the anagen phase again before delivery. The occipital area is the last area in the scalp to enter the telogen phase and does not do so until birth. Therefore, shedding of hair in the first weeks of life is normal and the pillow, which is often blamed, only aids this shedding.
Scientific journal is a periodical publication intended to further progress of science, usually by reporting novel research. There are thousands of scientific journals in publication, and many more have been published at various points in the past. Most journals are highly specialized, although some of the oldest journals publish articles and scientific papers across a wide range of scientific fields. Scientific journals contain articles that are peer reviewed, to ensure that articles meet the journal's standards of quality, and scientific validity. The publication of the results of research is an essential part of the scientific method. If they are describing experiments or calculations, they must supply enough details that an independent researcher could repeat the experiment or calculation to verify the results. Each such journal article becomes part of the permanent scientific record.
