1A Hair Type Guide – How To Make Your Straight Hair Stand Out

There are many hair shades, styles, and colors in the world. It isn’t easy to make sense of every hair type without first categorizing it and studying it. People’s hair types remain the same throughout their lives. Hair specialists have categorized hair into 12 distinct patterns between 1A and 4C to elaborate how curled or straight the hair is and how the type affects styling and hair care. That is because any type of styling is temporary, and hair grows back to its natural pattern after some time.

What is 1A Hair?

Hairstyles are often based on how hair curls. This classification has four main types of hair: type 1 hair is straight, type 2 hair is wavy, type 3 hair is curly, and type 4 hair is coily

The extent to which your hair curls is determined by the shape of your hair follicles. 

1A hair type falls in the type 1 hair category with no natural curls. Type 1a hair is very rare and is defined as straight, fine strands, shiny and oily. If you have 1A hair it means that your hair cannot hold curls and will naturally produce a lot of oil that leads to its shine. This hair type ranges from fine to superfine thickness and has a very thin volume.

How to Determine Your Hair Type

Knowing your hair type is vital to giving your hair the proper care it needs. The most pressing question everyone has is how you determine your hair type. We will properly define all the 12 hair types so that it is possible for you to notice your hair pattern and give it proper care.

For Men

The four main hair types are depending on the pattern of curls on your hair. Since the hair pattern is natural, any attempt to modify it is often temporary, and the hair regains its pattern after a short period. A good recommendation for men is to check the curl of their hair every 3 inches to gauge on which of the four main hair patterns your hair falls. 

Type 1 hair lacks a distinguishable curl pattern and is easy to tell apart from hair other types. It is less vulnerable to styling and weather damage compared to other hair types. Suppose your hair is not vulnerable to teasing. The grading of the hairstyle from A to C goes from fine to curl-resistant strands. The main difference is that grade a is thin, b medium hair while c has more hair that can make curls.

Wavy hair is the hallmark of type 2 hair; its curls are not so intense as to make it curly hair. Like type one hair, it is also graded from grade a to c representing a shift from fine and thin to coarse and curly hair. Type 2 hair is less oily compared to type 1 though it tends to frizz out. 2A has natural, beachy, and loose waves that form a C shape when dry. It is the least frizzy of type 2 hair. Type 2B has waves that are clearly defined and tightly drawn and form an S shape when dry. Type 2C has defined waves that begin at the hair root to the tip; it forms loose spiral curves that form an S shape and is the frizziest type 2 hair.

Type 3 hair has an S shape due to the natural curls and forms ringlets naturally defined. Type 3 hair tends to be dry owing to its texture. It is easier to style compared to type 2—the trends in type 3 run from loose curls to corkscrew curls. 3A has natural loopy curls, while 3B is coarse and dense. Both 3A and 3B form an S shape. 3C has a corkscrew shape with a circumference the size of a pencil. It is more voluminous than A and B.

Kinky hair or coiled hair is what constitutes type 4 hair and is commonly associated with people of African roots. The hair grading runs from tightly coiled in 4a to Z-angled in 4C. The 4A hair strands are fine and wiry with a noticeable curl pattern. 4B pattern is less defined because the coils are tight and often resemble a zigzag pattern. 4c is the curliest hair type; it is delicate and can shrink to 70% in size.

For Women

There is virtually no difference between the hair pattern in men and women. Interestingly men and women have the same hair texture, and the hair types are similar across both genders. The only noticeable difference is men tend to crop their hair and keep it short while women grow longer hair. The use of different sterling products and haircuts brings most of the distinction between women’s hair and men’s hair.

Women’s hair type follows the same pattern as men’s and ranges from type 1 for the straightest hair, type 2 for wavy hair, type 3 for curly hair, and type 4 for kinky hair. There is a reduction in the amount of sebum that reaches the tip of the hair from type 1 to type 4 and across the different grades in each hair type. The decrease in the oil causes the hair to curl and increase in volume. While 1A is straight and thin, 4C is kinked and fluffy.

A good tip is to apply the moisturizer from the ears down. You can use deep conditioning treatments monthly to reduce dry and frizzy hair.

Myths on 1A Hair

While you are taking care of your hair, you may have come across some tips; however, some of them are misleading and could lead to breakage of your hair. Here are the most common myths.

Using high-temperature styling will help maintain straight hair

A high-temperature setting can damage any hair and cause breakage and frizzing. You should adjust the heat setting of the blower or styler depending on the thickness of your hair. But it is a good practice to keep temperatures low to medium and use a heat protectant before styling.

Cold Water helps to keep hair shiny and straight

Coldwater doesn’t affect the straightness or curl of hair. The water molecules close the hair cuticle and lock in moisture and help keep the hair moisturized. Moisture helps to retain hair luster; however, it doesn’t affect the curl in any way.

Combining hair from root to tip promotes straight hair.

Hair combing helps to give hair a temporary style. The problem with using a comb is that it breaks hair and causes frizzes.

  • Do not wash your hair with hot water.

  • Do not use heavy serums or butter.


  • Comb your hair with fingers rather than a brush.
