Neonatal Occipital Alopecia (transient neonatal hair loss) is common alopecia that develops in the occipital area in the first few months of life. It was previously wrongly attributed to the 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.
