What kind of hair is 2a?
Type 2A hair is the least wavy type. It has loose subtle “S” shaped patterns and usually looks straight at the roots with soft bends or flicks at the ends. Usually smoother and thinner with a fine texture.
Features:
- Type 2a hair is loose and in a “S” shape, and the roots are often flat.
- Type 2a hair has less natural volume at the roots because it tends to lie flat.
- They tend to get greasy faster because natural oils can easily move down the hair shaft.
- Can be straightened or have waves added easily with the right tools and methods.
Helpful tips
The roots of type 2A hair are almost always completely straight when you examine them after natural drying.
When type 2A hair dries it doesn’t seem to shrink up its length stays almost the same whether it’s wet or dry.
Because the pattern is so loose oils from the scalp move down the shaft quickly. Roots get greasy in 24 to 48 hours.
When you brush dry hair the waves go away right away and the hair either straightens out or gets a little puffy.
When you put on a lot of curl cream or butter your hair looks limp, wet or flat right away.
What kind of hair is 2b?
Type 2B hair makes S-shaped waves that usually start in the middle of the hair and go down to the ends. The roots on the other hand stay straighter it falls somewhere between the barely-there waves of 2A and the tighter more textured curls of 2C 2B hair naturally has more volume and a pretty wave pattern, but it can get frizzy easily, especially when it’s humid. A little styling product can help keep the waves defined all day. You can see type 2B wavy hair in the next picture.
Signs that you have 2B TYPE HAIR WAVES include:
- You will see S-shaped waves that start in the middle and go to the ends.
- Sometimes waves start at the roots and go to the middle where they are straight.
- Your hair looks short when it’s dry and longer when it’s wet.
- Men’s 2B curls often look like relaxed waves instead of real curls. This makes this hair type popular for styles that don’t need a lot of work.

Confusion about the 2b hair type
People often get 2B hair wrong by thinking it is straight or fully curly which causes them to not take care of it properly which makes it flat frizzy and damaged.
Here are some common myths about type 2b hair that can cause problems:
2B is the same as straight hair or hair that is 3A curly.
Some people think that 2b hair is straight while others think it is curly.2B is a different type of wavy hair that is between 2A loose barely there waves and 2C tight almost curly waves it doesn’t make ringlets or corkscrew curls but it also doesn’t make straight hair.
type of hair that doesn’t need much care.
2B hair needs special regular care to keep its wave definition because it tends to get dry and frizzy it is more likely to frizz than types 1 or 2A.
Brushing when they are dry can mess up the wave pattern which can cause a lot of frizz and damage.
Using thick moisturizing products can make 2B hair dry which makes it easy to weigh down using thick oils or heavy creams can make your roots greasy and your waves limp and flat.
The first step in picking the right curly hair products for 2b waves and keeping your hair looking soft defined and frizz-free is to know what type of 2b hair you have.
What kind of hair is 2C?
Type 2C hair has strong well-defined waves and is in between wavy and curly hair. These waves usually start at the roots adding a lot of volume and texture to the hair from the top down. The S pattern in 2C hair is tighter than in other wavy types and usually stays in place.
2C hair can also be more likely to get frizzy and dry especially when it’s humid or not getting enough moisture. This is because the waves are more noticeable it usually needs a little more moisture and frizz control than 2B hair to stay smooth and defined.
Features:
- Type 2c wavy hair has tighter more defined S-shaped waves that start at the scale and go up to the roots.
- Hair that is naturally thicker and has more texture.
- Get frizzy more likely to frizz especially in humid weather conditions often appearing rough.

Men with 2C hair will notice that the texture of their hair becomes more pronounced as it gets longer which often shows off curls that were hidden before naturally.
Tips for professionals
- Let your hair air-dry without any products after you wash it to see how it really looks when your hair is wet 2C hair often looks less curly and more like a very stretched-out S-shape the wave pattern gets tighter and more defined from the scalp to the ends as it dries in the air.
- 2C hair is very prone to frizz because the waves are so tight.
There are a lot of wrong ideas about 2c hair type.
People often get Type 2C hair wrong because it is in between wavy and curly hair and has traits of both.
It’s only hair that curls but 2C hair is technically wavy but it can have some spiral ringlets especially on the ends instead of tight corkscrews like Type 3 hair it has a very visible S pattern that sets it apart clearly.
It stays hydrated on its own but 2C hair is the driest of the wavy types even though it is wavy. The tight S shape makes it hard for natural oil from the scalp to move down the hair shaft so they need products that are more hydrating.
It’s fine to brush it but brushing dry 2C hair is a big mistake because it breaks up the defined waves makes a lot of frizz and can make the hair look like a big puffy mess.
It doesn’t need a lot of hold but because 2C waves tend to lose their shape or fall flat during the day they need strong-hold products like gels to keep their shape.

The Science Behind How Type 2B and 2C Hair Acts
The shape and angle of the follicle
Follicles are tiny holes in the scalp where hair grows the shape of the follicle determines the type of hair that grows from it. For example wavy hair grows from oval-shaped follicles straight hair grows from perfectly round follicles and curly hair grows from more flattened follicles.
When hair grows out of the scalp at an angle it often starts to form a S shape.
Genetic
Hair texture is a polygenic trait which means that both parents pass down different genes that affect it. Sometimes environmental factors can change how these genes are expressed which could change the texture of your hair.
Regulating temperature
The S patterns of waves and curls make it harder for natural scalp oils to move down the shaft which is why wavy hair can be drier than straight hair.
Building chemical bonds and protein structure
Keratin a type of protein makes up most of hair the way these protein chains stick together affects how the hair bends and forms.
Why do some people have more than one hair pattern on their head?
Having more than one hair pattern on your head is normal and common this multitextured hair can have straight parts and tight coils and it can change depending on biological and lifestyle factors.
Genetics
Genetics is the main thing that decides the shape and size of hair follicles it is possible for different patterns to show up on different parts of the same head.
Damage to Hair
Using heat styling tools like flat irons and blow dryers as well as chemical treatments like bleaching and coloring can weaken the hair structure.
Things that affect the environment
When it’s humid some parts of your hair may swell and frizz while others may stay flat long exposure to UV rays from the sun can also dry out hair.
How You Sleep
Sleeping on your back or on one side all the time can put uneven pressure on your hair.
How to Style
Brushing too hard or always pulling hair into tight styles can change the curl pattern in some places.
Buildup of products
Heavier oils and products can make some parts especially the top layers look less curly than they really are.
Changes in hormones
Changes in hormones during certain stages of life like puberty pregnancy or menopause can affect how genes work.
