The hair spectrum includes rare types like Type 1c (straight and thick) and Type 4c (tight coils with zigs and zags). The protein produced by the TCHH gene plays a role in the development of the hair shaft. Understanding these geographical and genetic variations offers a fascinating glimpse into human evolution and migration patterns.
Decode your curl pattern once and for all with these expert tips
Illnesses, medication, and treatments like chemotherapy can influence your hair’s appearance.

This mousse has also become a TikTok favorite for its curl-defining features and incredible aroma. The product is made with TeraBond technology that fights breakage and repair hair structure. With no dyes, parabens, or sulfates this styling jelly helps control frizz without any harmful ingredients to compromise the health of your strands. This hair oil reduces hair breakage while encouraging curl definition perfect for those with type 2 hair who want their curls to be more prominent.

Micro-shaft structures are formed and supported by biochemical components, comprising proteins, lipids, water and other cellular material. The two shaft sublayers are consecutive in nature, with the biocomposition having a regulating effect on the formed structures. The shaft biocomposition describes not only relevant biomolecules but also the chemical bonds that drive underlying bonding networks, which are pivotal in fibre curvature.
For example, sun exposure can temporarily cause more freckles to appear. Some people can curl up the sides of their tongue to form a tube shape. In 1940, Alfred Sturtevant observed that about 70% of people of European ancestry could roll their tongues and the remaining 30% could not. There are a handful of additional genes that have recently been identified and might play a role in regulating hair shape. In addition to the shape of the hair follicle, scientists believe that differences in cell behavior during hair fiber production contribute to hair shape.

You can use a hair diffuser – that round blow dryer attachment with fingers – to really play up and define your curls. Work your hair into small sections and then scrunch each section to create defined curls. Torres explained that curl types are very easy to find and that the lower the defining letter, A-C, the looser the curls are. Also known as a "lob", a long-length bob is a great option if you have longer hair and you're on the fence about a dramatic chop. Let's be honest, mid-length styles always look good and they're wonderfully low-maintenance for curly and textured hair as they don't require cutting as often as a shorter bob. A blunt bob, might require regular trims to keep it looking razor sharp, but there's no denying how cool this cut looks.
“Gently encourage the spring of the S shape to form when drying and styling hair by compressing and bouncing it using the palm of your handheld flat and facing upwards, in a repeated lifting motion,” says François. Using these basic principles of inheritance, it is possible to predict the percentage of different dominant traits expressed in the offspring, in a wide range of reproductive events. However, most traits within a phenotype of a complex organism are controlled by a number of different genes, so the reality is not always as simple as in Mendel’s experiments. When these were bred to create the first generation, the offspring were Pp, having each taken a dominant allele from one parent and a recessive allele from the other. So, although both alleles were passed down, the white color alleles were masked by the dominant purple color alleles.
Your texture also will have more fluff and volume, or a zig-zag shape, rather than a loose wave or curl. This pattern is very delicate and can break easily as the curls can sometimes group and form knots. You have to moisturize continuously, give your strands tons of love with added hot oil and conditioning treatments,” says Unilever Global Hair Care Ambassador and celebrity hairstylist Lacy Redway. Redway has worked with type 4 beauties including Amanda Gorman, Regina King, and Amandla Stenberg.
On the other hand, recessive traits need 2 copies, one from each biological parent to be expressed. Dominant traits need only a single copy from either biological parent to be expressed. Numerous studies have shown that genes influence not just the texture but also the predisposition to baldness and graying. So, if you’re wondering why your hair acts a certain way in different weather, or why it’s changed over time, it might be down to these environmental and lifestyle factors.
The CTS generates and maintains the other component of the mesenchymal compartment, namely the dermal papilla (DP). Sitting embraced by the bulb matrix at the follicle base (figure 1), the DP is key in fibre production. The epithelial compartment is composed of the bulb matrix, inner root sheath (IRS), outer root sheath (ORS) and the growing fibre. At the widest part of the DP, the Auber line distinguishes between proliferation activities in the lower bulb and differentiation activities in the upper bulb. The IRS and ORS are rigid, multi-layered structures that appear to have a topographically guiding role for the growing fibre. Forming the outer epithelial envelope at the junction with the CTS, the ORS extends up to the follicle orifice.
While there’s no universal answer to whether curly hair is rarer than straight, it varies across populations. In some regions, curly hair may indeed be less common, contributing to its perception as a distinctive and unique trait. Curly hair, often a topic of genetic intrigue, sparks curiosity about its inheritance. Contrary to common belief, even parents with straight hair can indeed have curly-haired offspring. One study found that 55% of people place their left thumb on top, 45% place their right thumb on top, and 1% have no preference.
Cuticles are cysteine and glycine rich [61], with the outer layers comprising highly cross-linked UHS-type proteins and the endocuticle mostly composed of low-sulfur residues and acidic and basic proteins. Cuticular KAPs are high in cysteine, serine, glycine and proline content [13,33–35]. Biochemically, cortex KPs are low-sulfur structures, with a high concentration of basic and acidic residues when compared with cuticular proteins [62]. KPs are also low in proline [63], which is detrimental to the α-helix structure. In wool fibres, concentrations of cysteine, cysteic acid, threonine and proline were shown to be higher in PCs than in OCs, whereas tyrosine, glycine, phenylalanine and leucine were dominating in OCs [64,65]. In certain but not all studies [65], aspartic acid concentrations have also been found to be dominant in OCs.
