Shingling aims for a seamless blend with no visible boundary between lengths. By cutting small sections and letting the hair fall naturally, the ends are encouraged to lie into each other rather than meet at a sharp point. This creates a soft, natural finish where any line or demarcation is eliminated, giving the hair a flat, flowing look like shingles layered over one another. A sharp, defined line, an even-length all around look, or a blunt edge at the ends would contrast with the purpose of shingling, which is to remove that definite line and produce a blended appearance.

In anatomy, the skull’s formal term is cranium. This word is the precise, technical name for the bony structure that encases the brain and forms the head’s protective case. The common word “skull” is used in everyday language, but the term cranium is the correct formal term. It helps to know how the skull is organized: the neurocranium refers specifically to the braincase—the bones that protect the brain—while the cranial vault denotes the top and sides that form the domed roof. The facial bones belong to a different group called the viscerocranium. So for the whole skull, cranium is the proper term.

Base colors in artificial hair colors come from the basic pigment families: primary and secondary colors. These form the starting set that colorists mix to achieve most shades. Primaries (red, yellow, blue) can be combined to create secondaries (orange, green, violet), and from there even more nuanced tones can be built. Tertiary colors—mixed from a primary and a secondary—are useful in formulations, but they aren’t typically used as the base color group for standard hair color building blocks. Understanding that the foundational palette is primaries and secondaries helps explain how designers predict how a dye will interact with hair, allowing you to hit warm, cool, or neutral targets as needed.

Curl reforming is a chemical service used to reshape very curly hair into a larger, looser curl pattern. It’s commonly called a soft curl perm. The process works by breaking and then reforming the hair’s internal disulfide bonds so the curl texture relaxes from tight coils into broader, softer curls. This is different from straightening or removing curl, and it’s not a coloring treatment. After the reformation step, a neutralizer sets the new curl pattern, and proper aftercare helps maintain the results.
