Divine Order and the Prohibition of Foreign Hair Use

The religious justification for Christians regarding the transplantation or use of another’s hair is based on the idea that applying someone else’s hair to a natural head constitutes a violation of the divinely established order and symbolic identity, especially within the context of family relationships. In particular, several cited authors emphasize that adorning the head with another’s hair (or artificially transplanting someone else’s hair) is an ungodly act, as it involves issues of spiritual leadership and symbolism, where the head of the husband is Christ, and for the wife, the husband is the head.

For example, one source explains: "However, placing another’s hair on the head should be completely abandoned; adorning one’s head with someone else’s hair, applying dead locks thereto is truly ungodly; because on whom will the presbyter then lay his hands; whom will he bless?

Not the adorned wife, but another’s hair, and because of it, another head. If for the husband the head is Christ and for the wife the head is the husband (1 Cor. 11:3), then is it not doubly sinful to fall into such a transgression?" (source: link txt)

Similarly, it is stated that this practice contradicts not only aesthetic norms but also spiritual discipline: the head, sanctified by baptism, is considered a place where “remaining” foreign hair strands—which could introduce an element of debauchery or alien influence—should not accumulate. One text warns:
"Do not place on the head, sanctified by baptism, the mortal remnants of any beggar who died of debauchery or any outlaw condemned to die on the scaffold. What strangeness, to continuously transgress the commandment of God! ..." (source: link txt)

Thus, within the Christian worldview, there is a strong emphasis on adhering to the prescriptions set forth in the apostolic teachings. The alteration of the “natural” appearance, expressed through one’s natural hair, is viewed as a deviation from the divine order, wherein a person must preserve their intrinsic identity, established in the divine plan, rather than seek to complement or alter it by using another’s hair. This argument is framed within the broader context of teachings on modesty, spiritual purity, and adherence to established traditions concerning one’s appearance.
