■ The plaintiff is engaged in the business of *625 сonducting a school in Boston for the purpose of teaching students hairdressing and manicuring, and is registered under G. L. (Tеr. Ed.) c. 112, § 87BB, as amended. This bill in equity seeks a binding declaration as to the constitutionality of St. 1949, c. 345 (which amends c. 112, § 87U, as appearing in St. 1941, c. 626, § 3), entitled, “An Act prohibiting hairdressing schools charging for services or materials used in connection with hairdressing or manicuring.” The statutory provision is: “No student shall practice hairdressing or manicuring upon any paying customer, and no school shall directly or indirectly make any charge for services or materials in connection with such practice of hairdressing or manicuring.” The defendant board appeals from a final deсree (1) adjudging that in so far as c. 345 “provides that no hairdressing school shall directly or indirectly make any chargе for materials used by said school in connection with the practice of hairdressing or manicuring [it] is not a valid exercise of the police power of the Legislature and is in violation of the Constitutions of the United Statеs of America and the Commonwealth of Massachusetts,” and (2) permanently enjoining the board from enforcing thаt portion of the statute. The plaintiff did not appeal, and no argument has been addressed to us based uрon the absence of a ruling as to that part of the statute prohibiting a charge for services.
The defеndant board contends that the declaratory judgment statute, G. L. (Ter. Ed.) c. 231 A, as inserted by St. 1945, c. 582, § 1, does not cover questiоns relating to the action of boards under c. 112, which, it is argued, provides an exclusive procedure. Among the сases doubtless relied upon, but not cited, are

v.
Board of Registration in Optometry,
The present case, dealing with the validity of the enabling act, cuts in ahead of procedural questions arising under the act, and raises issues appropriate for consideration upon a bill for declaratory relief. A similar result has been reached in decisions elsewhere.

v.
Wheeler,
The judge made a report of the material facts found by him. Some of these we summarize. In the plaintiff’s school the studеnts work on one another arid on models. Models are friends or relatives of students, or persons with previous еxperience as models. The school does not advertise for or solicit models. When a model entеrs the plaintiff’s place of business, she announces the work she wants done, and is then assigned to a student. No charge is made to a model for services. The statute in question was passed as a result of a bill filed by an assoсiation of private “beauty shops.” Following the passage of the statute the defendant board chargеd the plaintiff with its violation and set a date for a hearing. The board intends to enforce c. 345. The use of live models is of advantage both to students and to the general public. It makes possible a diversified training, and enables students to become more proficient when, after graduation, they serve the general public. The making of a charge to models for the cost of materials used upon them tends to be in the public interest. In so doing thе students become accustomed to the use of “standard brands” of materials rather than • “inferior brands.” The prоhibition against charging for the cost of *627 materials has no rational tendency to promote the safety, hеalth, morals, or general welfare of the public. It has no rational or reasonable bearing on cleanliness, sanitation, or the prevéntion of communicable diseases.
The principles pertinent to the issue of constitutionality are well known. All rational presumptions are made in favor of every legislative enаctment, and invalidity will be found only when a statute is in manifest excess of legislative power.

v.
Unemployment Compensation Commission,
*628
We have not found it necessary to decide whether the statute is void, in whole or in part, because of a discrimination against hairdressing schools, in that it does not also apply to institutions engaged in the training of barbers. See
Opinion of the Justices,
Decree affirmed.
