BR-202024017950-U2 - CONSTRUCTIVE ARRANGEMENT APPLIED IN A HEAD MEASUREMENT STANDARD FOR PRE-MOLDED HAIR PROSTHESES

Abstract

This utility model patent application pertains to the personal care industry, specifically for the manufacture of hair prostheses. The aforementioned head measurement standard was designed to simplify the production of pre-molded hair prostheses, eliminating the need for professionals to travel to the client to take measurements. This standard is applied around the head using specific reference points, creating a precise baseline for both the professional and the client. Given the difficulties in scheduling in-person appointments, this method facilitates not only the process of obtaining and maintaining prostheses but also reduces production costs, making the service more accessible and efficient.

Description

TECHNICAL FIELD [001] This utility model patent application pertains to the personal care industry, applied to the manufacture of hair prostheses, notably, said head measurement standard was designed to simplify the manufacture of pre-molded hair prostheses, eliminating the need for the professional to travel to the client to take measurements. This standard is applied around the head, using specific reference points, creating a precise basis for both the professional and the client. Amidst the difficulties in scheduling in-person appointments, this method facilitates not only the process of obtaining and maintaining prostheses, but also reduces production costs, making the service more accessible and efficient. HISTORY OF THE TECHNIQUE [002] One of the earliest pieces of evidence of the use of hair prostheses comes from Ancient Egypt, where wigs and prostheses were used by both men and women. These wigs were made of human hair, sheep's wool, or palm fiber. In addition to their aesthetic function, they also provided sun protection and were symbols of social status. [003] In both Ancient Rome and Greece, wigs and hairpieces were used by women and men, especially for aesthetic reasons. During the Roman Empire, women wore wigs made from blond hair brought from Germania, while dark hair was more valued in Greece. [004] During the Middle Ages, the use of hair prostheses decreased in Europe, but regained popularity during the Renaissance. In the 17th century, the use of wigs became a status symbol among the European nobility, especially in France, during the reign of Louis XIV. The wigs of the time were voluminous and elaborate, made of natural or synthetic hair. [005] In the 19th century, hair prostheses became more accessible and less exaggerated. In the 20th century, with advances in technology and medicine, more sophisticated hair prostheses began to emerge, made of lightweight materials and with a natural appearance. With the development of effective adhesives and fixation techniques, hair prostheses became a viable option for people suffering from hair loss for medical reasons. [006] In recent years, the hair prosthesis industry has evolved significantly, with the development of techniques such as hair injection strand by strand and the use of materials such as silicone and advanced polymers to create a base that mimics the scalp. Modern hair prostheses can be highly customized to suit the lifestyle and needs of each user. State of the Art Analysis [007] Research conducted in specialized databases revealed documents related to head measurement for hair prostheses, such as document number EUA7752769B1, which deals with a "SELF-APPLICABLE MEASUREMENT KIT FOR HAIR REPLACEMENT MOLD". A self-applicable measurement kit for a hair replacement mold is provided. The kit comprises a shaping wire, two side wires, a shaping sheet, and a domed support pad. The shaping wire is adjusted to fit the desired hair boundaries and to be fixed to the head. The two side wires are draped down towards the user's chin and tied to secure the shaping wire in place. The shaping sheet covers the head using the shaping wire to imprint the head shape, and the shaping sheet is compressed to imprint the position and shape of the shaping wire. The domed support pad prevents the molded shaping wire and shaping sheet from deforming. The two side wires facilitate securing the hairpiece to the head and imprinting the shape of the head, keeping the hairpiece in place and adjusting to the desired hairline limits. [008] Document No. RU2319428C2, which deals with a "HAIR PROSTHESIS AND METHOD OF MANUFACTURING A BASE FOR A HAIR PROSTHESIS", FIELD: manufacture of partial or complete wigs or hair prostheses to replace missing hair in problem areas of the head. SUBSTANCE: The hair prosthesis has a forehead part made of flexible material of the desired contour and strips having front and back faces approaching each other in the posterior region of the head to form restrictive contour strips and contour-defining strips. The base of the prosthesis is made of material having a smooth sliding surface with successively applied impregnation layers of adhesive substance, and consists of strips overlapping each other along the arc of the circle and provided with margins. The aforementioned strips are made of bonded material defining a three-dimensional spherical shape of the base with part of the forehead and part of the back of the head, including restrictive contour strips, contour-forming strips, and a strip for the back of the head. The front faces of the strips are tightened over the front surfaces of the forehead part, for example, along the shared restrictive thread of the material. All overlapping portions of the strips are fastened to each other by, for example, stitches. Parts of the strips in the left and right temple regions of each strip are fixed, for example, by gluing to the back of the head of the base. The hair prosthesis is adapted for constan
