Forty pregnant women attending the high-risk and normal obstetric clinics were evaluated for parietal scalp hair stage ratios during the second and/or third trimesters. In seven of the ten high risk patients from whom hair samples were obtained on two occasions, there was an observed fall in anagen hair percentages. Two of these had unfavorable outcomes, including severe anomalies and fetal death. These results are preliminary, but indicate the need for further evaluation of the anagen percentage as an indicator of pregnancy outcome.
