April ___, 1999




Regis Corporation
7201 Metro Boulevard
Minneapolis, MN  55439

Gentlemen:

I have acted as counsel to Regis Corporation, a Minnesota corporation (the
"Company"), in connection with the Registration Statement on Form S-4 (the
"Registration Statement") filed by the Company with the Securities and Exchange
Commission under the Securities Act of 1933, as amended (the "Act"), relating to
the proposed issuance of up to ____________ shares of the Company's Common
Stock, par value $.05 (the "Common Stock"). The Common Stock is being registered
in connection with the merger of Regis Merger Sub, Inc. (the "Merger Sub"), a
wholly owned subsidiary of the Company, with and into The Barbers, Hairstyling
for Men & Women, Inc. ("Barbers") (the "Merger") pursuant to an Agreement and
Plan of Merger among the Company, Merger Sub, and Barbers, dated as of January
25, 1999, as amended (the "Merger Agreement"). The Common Stock is described in
the Proxy Statement/Prospectus included in the Registration Statement to which
this opinion is an exhibit.

I have examined an executed copy of the Registration Statement (including the
exhibits thereto), the Articles of Incorporation of the Company filed with the
Secretary of State of the State of Minnesota and such corporate records,
documents and other instruments and have made such other examinations and
inquiries as I have deemed necessary to enable me to express the opinions set
forth herein.

Based upon the foregoing and subject to the qualifications and limitations
stated herein, and assuming the effectiveness of the Registration Statement
under the Act, I am of the opinion that:

                  The shares of Common Stock issuable upon the Merger have been
         duly authorized and, upon issuance, delivery and exchange as described
         in the Merger Agreement, will be validly issued, fully paid and
         nonassessable.

The opinions set forth herein relate solely to the laws of the State of
Minnesota and the federal laws of the United States.

I hereby consent to the use of this opinion as an exhibit to the Registration
Statement and to the use of my name under the heading "Legal Matters" in the
prospectus forming a part of the Registration Statement.

Very truly yours,

REGIS CORPORATION


By
