The Priest cuts four locks of hair from the child's head in the form of a Cross. This is an expression of gratitude from the child, who having received an abundance of blessings through the Sacraments of Baptism and Chrismation and having nothing to give to God in return, offers part of its hair, as a first-offering to God. In the Old Testament, hair is seen as a symbol of strength. The child, therefore, promises to serve God with all its strength.
