Hair type is determines by the follicles and giving credits to genetics follicles vary in size, shape and thickness, which determines your hair shape and thus hair type.
Coils Type: This hair type does not usually curl, even with products. It is very tightly coiled with a high dryness factor. This hair type can have a range of porosity but it usually falls in the high porosity category. This hair type comes in all densities but is usually of a very coarse texture.
Kinky Curly Type: Micro spirals, zigzag curls that do not appear when you look at it. When you look closer, Curls are step-like in most areas of the head with some tightly spiraled curls in other areas (for some). This hair type can be a combination of textures and porosity. For some, curls contract tightly throughout the heard, with lots of small spirals. Hair can be seen as being dense but is usually fine and breaks easily. This hair type also has a high shrinkage factor no matter no weather or humidity.
Curly Type: Varying curl patterns throughout your hair, with some areas having loose and others tighter curls (usually around the face and nape of the neck). Hair can appear longer or shorter depending on the weather and humidity. This hair type is mostly of a medium texture. Some others have mostly big, loose, spiral curls that vary in size which can be of any texture but is usually of a medium texture. This same hair type can have some with fine spiral curls that resemble the hair of a young child. This curl type is usually of a fine texture.
Wavy Type: Ranges from Loose, stretched out S-waves throughout the hair, which can be of any texture, to some with waves that are less stretched out and more distinct (S-waves). The S-waves can be of any texture but is usually of a medium texture. In this same category you’ll see some with a combination of distinct S-waves with some spiral curls forming in different areas throughout the head. This hair type can also be of any texture.
Straight Type: Straight hair can range from thick to thin strands. Thick strands when shed, can easily be identified against most backgrounds and is usually of a coarse texture. Thin strands are sometimes translucent when held up to the light, having a fine texture. When this hair strand sheds, it can be hard to see, even against a translucent background. The hair strands that fall in the middle are neither fine nor coarse, but more of a medium texture.
Whatever type or category your hair falls under, all comes in 3 major textures Coarse, Medium, Fine. You can have a combination of all 3 on different parts of your head;
Hair texture is not an indication of porosity but more so of hair type, although that varies in terms of environmental stressors or types of products used.
Hair porosity just as hair type is a matter of genetics. You may not be able to change it. However there are manipulation techniques you can use to make your hair more manageable. Hash chemical treatments may also increase one’s hair porosity regardless of your hair type or genetic predisposition.
Hair easily absorbs water and products with the highest tendency to lose moisture- thus usually appear or feel dry. This type of hair porosity is usually a result of environmental or mechanical stressors, and types of products used. This type of hair porosity usually needs lots of detangler to untangle.
Products that highly balance moisture between the atmosphere and hair are highly beneficial to this hair type. With regular deep conditioning treatment to smooth down hair cuticles repair damages in some instances and bring moisture balance back to hair.
Hair is normally balanced with the atmosphere. The cuticle is compact and slows down moisture from leaving or entering it, thus doesn’t become overly dry or oily. This hair porosity needs little to minimal detangler to untangle. When the right products are used, it will readily absorb and retain them.
Hair’s cuticle is very compact. It is resistant, and does not permit moisture to enter or leave the hair shaft. This hair porosity type usually needs very little product to style or maintain. It easily and readily absorbs and retains products.
Hair is so diverse, especially curly hair, that we find it a bit constricted to fit them under a number system. We’ve created a hair chart that factor in hair texture, porosity, along with hair type to help one determine their hair and the products that would be best suited for their hair. Contrary to popular belief most heavy or oily products does not work for those with curly hair type.
You may find that a product that is working perfectly for someone with with coily or kinky curly hair also works for someone with naturally straight hair. The reason for this isn’t base on hair type but hair porosity and even texture. When it comes to finding hair maintenance products (cleansers, hair masks, leave-in, hair moisturizer) products, knowing your hair porosity is the main factor. However when its comes to styling products, such as those for curly hair or coily and kinky curly hair, a combination of hair porosity and types are the two factors to consider.
