I reply to your letter of Wednesday of Parshas Tetzaveh, in which you speak of the sheitel*. You say you do not know exactly what it corresponds to.
The purpose of a sheitel is to cover the entirety of one's hair. For it is not good that it be covered only in part.
You should also exert yourself that others wear it as well, explaining to them that by acting in this way one obtains health, material abundance, and true nachas* from one's children.
May Hashem bring it about that you give me good news on this.
