The Different Types of Type 4 Hair (4A, 4B, and 4C) and How to Care for Them - wowangel

Introduction

Have you ever left your hair loose and watched it go from 22 inches to about 11 inches in a few hours? Or struggled with dryness, tangles, and breakage and wondered what was going on?

Nothing is wrong with your hair. You may simply have a distinctive hair texture known as Type 4 hair.

Type 4 hair is characterized by tightly coiled or kinky strands that can shrink significantly when they are not stretched. While this texture gives Type 4 hair its beautiful volume and versatility, it can also make the hair more susceptible to dryness, tangling, and breakage.

This is because the natural oils produced by the scalp have a harder time traveling down tightly coiled strands to keep the lengths and ends moisturized.

However, Type 4 hair isn't one-size-fits-all. It is generally divided into three subcategories: Type 4A, Type 4B, and Type 4C. Each has a slightly different curl pattern and may respond differently to products, styling, and daily care.

In this article, we'll look at the characteristics of each Type 4 hair texture, how to care for it, and the types of products that can help keep your hair moisturized, healthy, and strong.

Type 4A Hair

Type 4A Hair

Type 4A hair is the most defined of the 4 hair types. It is characterized by its springy, dense, and S-shaped coils. Type 4A has a tight curl pattern that makes it retain moisture very well, but it is also susceptible to dryness.

Characteristics of Type 4A Hair

● Defined, loose coils

Type 4A hair has defined and relatively loose coils compared to its counterparts (4B and 4C). It typically forms tight, visible spiral ringlets or S-shaped coils that start at the root. These coils are about the width of a crochet needle. It could almost pass as 3C hair.

● Shrinkage

Similar to other coily hair, 4A shrinks significantly when it becomes dry. It often appears shorter than its actual stretched length when it is wet. But 4A hair doesn’t shrink as much as 4B and 4C. We can say it experiences 50% shrinkage when it becomes dry.

● Texture and density

The individual strands of 4A hair can range from fine and soft to thick and wiry. In other words, this category has varying hair texture and density. Typically, it depends on the individual. So, two people with 4A curls might have completely different overall fullness and look.

● Soft and delicate

Generally, 4A is more delicate compared to 4B and 4C. The individual fibers are softer, making it sit just between the boundary of 3C and type 4 hair. Not just that, the shape, shrinkage, and definition are different. While 4B and 4C experience higher shrinkage, 4A is more manageable. It also has the most defined curls of type 4 hair.

● Susceptible to breakage from excessive tension, heat, and chemical damage

Common concerns can include heat damage, chemical damage, and breakage from excessive tension. Since it has tight bends, the natural oils produced from the scalp (sebum) struggle to flow down the hair, making it dry and fragile. This means it is vulnerable to high temperatures and chemicals like relaxers and texturizers. It can also snap easily with high-tension styles.

How to Care for Type 4A Hair

Every type 4 hair category can be properly managed, cared for, and maintained with the right technique, products, and routine. While there isn't a set-in-stone approach that works for 4A hair, here are a few ways to get the best of your hair and make it flourish.

● Moisturize often

One of the key ways to manage 4A hair is to keep the hair moisturized. While moisture prevents the hair from drying out, using a good hydrating product that doesn't weigh down the hair is far more important. So, apply lightweight products that nourish the hair frequently.

● Detangle gently and minimize excessive manipulation

Always detangle gently and do not manipulate too often. Choose protective styles like twists and braids that keep the strands protected and limit daily styling.

● Deep conditioning regularly

Get a good deep moisturizing shampoo for weekly wash. It intensely hydrates, softens, and strengthens 4A hair. This helps combat dryness by penetrating the hair shaft.

● Limit excessive heat and chemical processing

4A hair is usually fragile and prone to dryness. To avoid damaging the strands, limit heat styling and the use of harsh chemicals.

● Avoid high-tension hairstyles

Do not style braids that are too tight or place too much tension on your scalp and hair. This can cause breakage and, in the long run, traction alopecia.

Best Products for Type 4A Hair

  • Shampoos and cleansers: help remove dirt, sweat, and buildup without drying the hair.
  • Conditioners and deep conditioners: help add moisture, smooth the cuticle, and prevent breakage.
  • Leave-in conditioners and moisturizers: hydrate, soften, and protect the tight coils that lose moisture quickly.
  • Oils and sealants: can help lock in moisture, reduce frizz, add shine, and trap water-based moisture inside the hair.
  • Styling products: help define coils, seal moisture in the hair longer, keep flyaways in humid weather, and make the hair pop.

Type 4B Hair

Type 4B Hair

The 4B hair is known for its sharp, Z-shaped zig-zag angles rather than smooth S-curved ringlets. It is less defined, but densely packed and really voluminous. Similar to other 4 hair types, it is also prone to dryness and very vulnerable to breakage because it is highly fragile.

Characteristics of Type 4B Hair

● Tighter, less-defined coils compared with 4A

Unlike the 4A type that has defined S-shaped coils, 4B are usually less defined. They do not form uniform curls or S-shaped curls, but have a zig-zag pattern.

● Z-shaped appearance

This hair category has an angular appearance and a tight, Z-shaped or zig-zag pattern. Its sharp, angular turns and bends make it really fluffy and voluminous, creating a cotton-like texture without natural definition.

● Significant shrinkage

While 4A hair is able to retain more moisture and shrinks just around 50%, 4B hair shrinks even more. The tight bends of the strands make it shrink significantly, usually around 60% of its original length and size.

● Thickness and density

While 4B hair has its own characteristics, strand thickness and density can vary. This unique combination can affect the hair's volume, strength, and how to care for it. This means it's possible to have fine 4B hair, coarse, or even in-between.

● Susceptible to dryness and tangling

Because 4B hair doesn't have the definition of 4A hair, the natural strands overlap, making it tangle easily. Also, the oil doesn't penetrate the hair very well, making the ends become very dry without care.

How to Care for Type 4B Hair

Here are some of the ways to care for 4B hair.

Note that with 4B hair, the priority is to moisturize and strengthen the strands, as they are fragile. 

● Focus on moisture retention

The goal isn't just to apply products to the hair, but to layer hydration to keep the strands from getting extremely dry.

Apply a water-based leave-in conditioner first, follow with a natural sealing oil, then finish with a moisturizing cream.

● Detangle carefully

Always divide the 4B hair into sections before detangling properly and carefully. This helps remove the knots and tangles in the hair without causing breakage or damage.

● Deep condition regularly

Regular deep conditioning can restore moisture and elasticity to the fragile strands of 4B hair.

● Reduce excessive manipulation and use low-manipulation and protective hairstyles

Since the strands are prone to breakage and dryness, it is not highly advisable to manipulate the hair often. Choose low-manipulation and protective styles such as braids, twists, and cornrows instead.

● Protect the hair and ends between wash days

Wearing satin or silk bonnets, styling braids to tuck the ends, and refreshing lightly daily with water and leave-in conditioner are some of the steps to protect the hair and ends.

Best Products for Type 4B Hair

  • Gentle cleansing products: will help clean the scalp, remove buildup, and reduce tangling.
  • Moisturizing conditioners and deep conditioners: restore lost hydration, soften the coils, rebalance pH, and lock in hydration.
  • Leave-in conditioners: ease detangling, provide moisture, and prevent breakage.
  • Hair creams and moisturizers: provide rich hydration, enhance curl definition, and seal and lock in moisture.
  • Detangling products: make combing easier and minimize breakage.
  • Oils and sealants: create a protective barrier, add shine, smoothen the cuticle, and lock in hydration.

Type 4C Hair

Type 4C Hair

This hair category features tight, dense, and micro coils that are naturally voluminous. It has minimal visible curl definition and is extremely prone to tangling.

Characteristics of Type 4C Hair

● Tight coils 

4C hair has very tight coils with less visible curl definition. The strands usually form tiny, densely packed zig-zags, either S- or Z-shaped, requiring manipulation like twists to show a visible curl pattern.

● Significant shrinkage

Just like the previous 4 hair type categories, 4C hair can appear shorter than its actual length. However, it can go shorter by up to 75%.

● Dense and voluminous appearance

4C hair usually has a dense and full look. The strands form extremely small, tight coils and sharp angles that stack up on each other, making it really voluminous.

● Dryness and tangling

Because 4C hair features the tightest and most densely packed Z-shaped coils of all the hair types, the hair has a great tendency to become dry and tangle easily.

● Thickness and density

The thickness and density of strands can vary across different areas of the head. The width is usually independent, meaning there can be fine, medium, and thick strands on the same head.

How to Care for Type 4C Hair

Maintaining 4C hair is all about maximizing moisture and minimizing breakage. So, let's see some ways to care for 4C hair.

● Prioritize moisture and hydration

The sharp bends in 4C hair mean moisture escapes much faster than in looser curl patterns. So, use water-based products to hydrate your hair properly.

● Detangle gently

Besides hydration, do not comb the strands roughly to minimize breakage. Instead, start from the ends and move upwards gradually to remove knots and tangles.

● Deep condition regularly

Get a good deep conditioner to restore moisture and prevent breakage. They can penetrate the hair cuticle deeper and provide moisture to the hair.

● Reduce frequent manipulation and go for low-manipulation and protective hairstyles

Fewer daily comb-throughs and restyling protect the hair from breakage and snapping easily. With low-manipulation styles, your hair can seal in the moisture from oils and leave-in conditioner to remain healthy.

● Protect the hair at night

Sleeping with a satin or silk bonnet helps protect 4C hair at night. It prevents tangles, moisture loss, and breakage that affects the growth of the hair. Smooth fabrics tend to stop rough rubbing against bedding that causes frizz and friction.

● Pay attention to the ends

The ends are the most fragile and oldest part of the hair. This makes them prone to fraying and splitting. By tucking them in and applying sealing oil, the strands stay moisturized and protected. Styles like twists and braids can keep them safe.

Best Products for Type 4C Hair

  • Hydrating shampoos and cleansers: preserve the natural oils while gently removing dirt and product buildup from the hair.
  • Rich conditioners and deep conditioners: restore hydration, improve elasticity, and soften the tight coils of 4C hair.
  • Leave-in conditioners: provide hydration, soften the coils, and reduce breakage.
  • Moisturizing creams and butters: trap water inside the hair and prevent it from getting extremely dry.
  • Detangling products: reduce friction and prevent breakage on wash days.
  • Oils and sealants: help lock in hydration and reduce friction.
  • Heat protectants: reduce moisture loss and protect the hair when using heat styling tools.

Can You Have Different Type 4 Hair Textures on One Head?

Understanding Multiple Hair Textures

Of course, you can. In fact, it is very normal to have different type 4 hair textures. Although the categories (A, B, C) help us differentiate between textures within a type, sometimes those with curly and coily hair tend to have more than one category.

Understanding Multiple Hair Textures

Meaning, the curl pattern at the back might be different from the front, or another section might have a different structure. For example, your hair may feature 4B and 4C hair or 3C and 4B hair.

This varies depending on follicle shape and angle. It could also be caused by genetics, hair length, weight, and even hair damage.

Some people might inherit multi-textured hair. So, it's typical to have tighter coils at the crown and looser waves at the back and sides.

But if it's caused by hair length and weight, shorter hair has less gravity pulling it down, making the tighter patterns spring up. But longer lengths can look looser because of the weight that stretches the curls.

Besides that, heat styling and chemical processing could be the cause. These processes can loosen some parts of the hair, causing them to become straighter than other sections.  

How to Care for Multiple Hair Textures

  • Adjust your routine by putting the different sections into consideration when caring for your hair.
  • Understand that one product or technique may work differently across the head. So, always take care of your hair in sections to ensure every part gets proper treatment.
  • Focus on how the hair responds rather than trying to force it into one specific hair type.

Conclusion

Your hair could be 4A, 4B, or 4C. These different categories have their distinguished characteristics, with one tighter than the other or more voluminous than the rest. Sometimes, you might even have more than one. So, the focus should be on knowing your curl patterns and treating them with their separate needs and care.

Every type 4 hair needs moisture, gentle handling, and low manipulation to flourish. Once you can understand your hair texture and its specific needs, you can manage it properly. Because healthy type 4 hair starts with understanding and caring for the hair you actually have.
