Hair

Type 1 is straight hair. No spiral, no repeating S, no pattern of any kind from root to tip, which is what separates it from every other family on the chart. It splits into three subtypes, and the split is not about how straight the hair is. All three are straight. What changes across 1A, … Read more

Type 2 is wavy hair. The strand travels in an S that repeats along a flat plane, which puts it between straight hair that never bends and curly hair that wraps around an axis. The three subtypes are not degrees of waviness so much as answers to one question: how far down the strand does … Read more

The answer repeated everywhere is 1A, the pin-straight, very fine type at the far end of the chart. It is also an answer nobody has ever measured. No published study has counted how common each of the twelve hair type codes is. The claim circulates because it has been copied between beauty sites for years, … Read more

Hair type describes the shape a strand grows in. Four numbered families cover the range, from straight through wavy and curly to coily, and each one splits into three lettered subtypes, giving twelve codes from 1A to 4C. Knowing the code is useful and it is also the smallest part of the picture. Three other … Read more

4C hair is the tightest pattern on the typing chart. The strand bends in a very fine zigzag with no consistent repeating shape, so no curl is visible in its natural state, and it can shrink by up to seventy-five percent, meaning hair that reaches the shoulder when stretched sits at the ear when dry. … Read more

4B hair bends rather than curls. Instead of wrapping into a spiral, each strand changes direction at sharp angles, tracing a Z down its length, and the result reads as dense and cloud-like rather than as visible individual coils. Those angles are the whole story of this hair type. They are why it looks fuller … Read more

4A hair forms tight, springy coils roughly the width of a crochet needle, and the coil traces a visible S rather than a smooth spiral. It is the first pattern in type 4, denser than anything in type 3 and more defined than anything above it in type 4. It is also the hardest code … Read more

3C hair forms tight corkscrew curls roughly the width of a pencil, packed densely enough that the eye reads texture rather than individual curls. It carries more volume than any other type 3 pattern and loses about half its length to shrinkage. It also sits on the busiest boundary on the chart. More people search … Read more

A great hair day can feel like a superpower, instantly boosting how you feel about yourself. It’s an experience that goes far beyond simple vanity; it’s deeply tied to our identity and self-perception. When your hair looks good, you often feel more prepared to face the world with confidence. This connection between our hair and … Read more

3B hair forms springy ringlets roughly the circumference of a permanent marker, tighter than a 3A spiral and looser than a 3C corkscrew. The curls start at or near the root, pack closely enough to read as a full head of volume, and hold their shape without much persuasion. The pattern is easy to recognise … Read more
