Hair Care Practices and Their Association with Scalp and Hair Disorders in African American Girls

The document discussed the association between hair care practices and scalp disorders in African American girls, specifically focusing on the interpretation of seborrheic dermatitis as "dandruff" or "dry scalp." The authors of the letter disagreed with some conclusions of the original study, suggesting that the frequent use of hair oil/grease, often containing sulfur, might actually correlate with seborrheic dermatitis rather than prevent it. They also questioned the conclusions about the frequency of hair washing and the role of hair extensions, suggesting that these factors might not be causal but rather related to different grooming practices. The letter emphasized the need for further investigation to better understand these conditions in this demographic.
