How does hair growth change with blood group?

摘要

The main objective of present study was to relate the hair growth with the blood grouping. 174 subjects participated in this study at Bahauddin Zakariya University, Multan, Pakistan. 3 blood drops were taken on a glass slide with some distance between them. A drop of anti- A serum was put on first spot, anti-B serum was put on second spot and anti-D serum was put on third spot. Agglutination in blood occurred so blood group was confirmed by observing agglutination in respective blood drop. Humans have 4 major blood groups. For example A blood group, B blood group, AB blood group and O blood group. Parents transfer the genes to their children which decide the blood group. Each parent can donate one allele to child. Blood groups are further characterized by presence or absence of RhD antigen. Red blood cells have this antigen on their surface. Blood group is positive if RBCs have this antigen and blood group is negative if RBCs do not have this antigen. In this way, total 8 blood groups are present.
