The board may license, with or without examination, any individual who has been licensed as an aesthetician, barber, cosmetologist, electrologist or manicurist under the laws of another state, which, in the opinion of the board, maintains a standard substantially equivalent to that of the commonwealth. The board may require additional education if it determines that the standards required for the licensing in another state are inconsistent with the standards in effect in the commonwealth.
The word ''state'', as used in this section, shall include the District of Columbia, any territory of the United States or foreign country, state or province.
