Comprehensive review of every well-known hair typing system including Andrew Walker, LOIS & Fia and includes the most common hair types found in black hair.
What’s your hair type? Are you a 3b or 4A hair type? Maybe – that is if you decide to use one well-known hair typing system. Your hair type could also be an “OS” or an “IS” according to a different hair typing system.

We’re asked very often about hair typing systems. More specifically – many naturals are interested in how to determine their hair type. Generally speaking – we don’t discuss hair typing very often because there are many things that each person must do to care for their hair regardless of their individual hair type.

Having said that, we do recognize that there are some differences associated with caring for certain types of hair. Furthermore, many women utilize hair typing systems to describe the way their hair looks.

I think it’s important to be clear about a few things before we begin discussing hair types. There are multiple hair typing systems – including the Andre Walker Hair Typing System, LOIS, and FIA’s Hair Typing System.

We don’t endorse or recommend any particular hair typing system, however we recognize that the system created by Andre Walker is substantially more popular well-known and communicated than the other hair typing systems.

Note: This doesn’t imply that Andre Walker’s system is necessarily the best or most accurate.

During this guide I will discuss very specific details associated with the most popular hair typing systems – beginning with Andre Walker, then LOIS and finally FIA.

Disclaimer: It’s very easy to incorrectly determine your hair type if you only look at the pictorial representations that have been provided. Please don’t rule out a particular hair type simply because your hair doesn’t look like the pictures below.

Andre Walker Hair Typing System

Andre Walker is famously known for creating a hair typing system or infamously known depending on your perspective. Andre reveals his hair typing system in a book titled Andre Talks Hair!.

Andre makes it very clear in his book that everyone has good hair regardless of ethnicity. He was hoping to immediately debunk the often ridiculous good hair vs. bad hair debate prior to diving into a discussion about hair typing.

Unfortunately, many people believe that Andre’s Hair Typing System is hierarchical and intentionally places kinky hair in the bottom (“worst”) category. Andre has made statements over the years that have offended many Type 4 women – including the following comment:

Andre Walker on Type 4 hair: “I always recommend embracing your natural texture. Kinky hair can have limited styling options; that’s the only hair type that I suggest altering with professional relaxing”. Type 4 hair types include the most common hair types found in black hair.

That statement started a tremendous amount of buzz on the internet. He later issued a statement to clarify his initial comments immediately following the Elle article on his personal website. Regardless of his original intentions, his comments definitely offended many women.

Even if you have a negative opinion of Andre Walker, I encourage you to read the book yourself and develop your own opinion of his hair typing system in Andre Talks Hair!. Andre’s system isn’t communicated accurately on many popular blogs that have written articles about the system. Having said that, let’s discuss the hair types defined in Andre Talks Hair!.

Type 1: Straight Hair

Type 1: Straight Hair

Type 1 Straight Hair: Generally speaking Type 1 hair is straight; however Andre categorizes this hair type into three very specific segments – Type 1A, Type 1B, and Type 1C.

  • Type 1A hair is described as fine, very thin and soft with a noticeable shine.
  • Type 1B hair is medium-textured and has more body than Type 1A hair.
  • Type 1C hair is the most resistant to curly styling and relatively coarse compared to other Type 1 hair types.

Type 2: Wavy Hair

Type 2: Wavy Hair

Type 2 Wavy Hair: Type 2 is wavy hair that usually isn’t overly oily or very dry. The thought is that Type 2 hair falls right in the middle of Type 1 and Type 3.

  • Type 2A hair is fine and thin. It is relatively easy to handle from a styling perspective because it can easily be straightened or curled.
  • Type 2B hair characteristically has waves that tend to adhere to the shape of your head.
  • Type 2C hair will frizz easily and it is fairly coarse.

Type 3: Curly Hair

Type 3 Wavy Hair
Type 3: Curly Hair

Type 3 Curly Hair: Curly hair textures have a definite “S” shaped curl pattern. Since the cuticle doesn’t lay flat, you will noticed that curly hair isn’t nearly as shiny as Type 1 (straight hair) or Type 2 (wavy hair) hair types.

  • Type 3A hair is very shinny and loose.
  • Type 3B hair has a medium amount curls, ranging from bouncy ringlets (spiral like curls of hair) to tight corkscrews (spiral-shaped corkscrew curls).
  • Type 3C hair isn’t a part of the Andre Walker Hair Typing System. Please see the “what’s missing” section below for more information.

Type 4: Kinky Hair

Type 4 Kinky Hair
Type 4: Kinky Hair

Type 4 Kinky Hair: Type 4 is “kinky” or more appropriately full of tight coils (tightly curled hair). Typically, Type 4 hair is also extremely wiry and fragile. Often times, it appears to be coarse, however it is really very fine, with several thin hair strands densely packed together. Note that type 4 hair is one the most common hair types found in black hair (african american hair).

  • Type 4A hair is full of tight coils. It has a “S” pattern when stretched, much like Type 3 curly hair.
  • Type 4B hair has a less defined pattern of curls and looks more like a “Z” as the hair bends with very sharp angles.
  • Type 4C hair isn’t a part of the Andre Walker Hair Typing System. Please see the “what’s missing” section below for more information.

What’s Missing? Now, Let’s Discuss Hair Type 3C and Type 4C

You’ll notice that Type 3C and Type 4C hair types aren’t mentioned in the discussion above, that’s because they were not included in the original Andre Walker system.

Type 3C was created after Andre Walker released his hair typing system by a community member at NaturallyCurly.com. The prevailing thought was that the original hair typing system left this hair type out. Consequently, Type 3C hair has been defined as tight curls or coils that look like corkscrews.

Type 4C, like Type 3C, isn’t an actual hair type according to Andre Walker’s Hair System. His comments are actually very simple regarding Type 4 (Kinky) hair – if you can see a definite curl pattern, then you have Type 4A hair. If you can’t identify a defined, specific curl pattern, then your hair type is 4B. I would imagine that the Type 4C hair type was created by a member within the natural hair community – just like the Type 3C hair type.

Hair Types

LOIS Hair Typing System (often spelled as L.O.I.S Hair Typing System)

The LOIS Hair Typing system appears to be dying a slow death, although there are many naturals that advocate for it over the more well-known Andre Walker Hair Typing System. LOIS was created by a website that is no longer active. The hair typing is considered by many to be very user friendly – due to its simplicity.

The LOIS hair typing system defines hair using three characteristics: (1) pattern, (2) strand size, and (3) texture.

Hair Patterns

The LOIS system defines the hair pattern by the letters LOIS. I’ll explain:

  • L = If your hair is dominated by right angles and substantially bends with nearly no curve, then you’re considered a pattern “L”.
  • O = If your hair strand curls or coils significantly and appear to be shaped like the letter “O”, then you’re considered a pattern “O”.
  • I = If your hair has no distinctive curls or bends and primarily lies flat against your head, then you’re considered a pattern “I”.
  • S = If your hair strand has “S” shaped curls or waves with defined hills and valleys, then you’re considered a pattern “S”.

Finally, it’s important to note that you may have several different LOIS hair patterns on your head. When this occurs, the system allows you combine LOIS letters to determine your hair pattern.

For example, your hair pattern may be an “OS” LOIS hair type. In this example, your hair would contain primarily a combination of “O” shaped spiral curls and “S” shaped curly waves with defined hills and valleys.

Hair Strand Sizes

Identifying your hair strand within the LOIS system starts with using a strand of frayed thread. One piece of a frayed thread (like a piece of sewing thread) is used as a proxy to determine the size of your hair strand. The general thought (according to the LOIS hair typing system) is that a piece of thread is approximately the size of medium sized strand of hair.

  • Smaller than a piece of sewing thread = Thin, fine hair strands
  • Size of a piece of sewing thread = Medium hair strands
  • Larger than a piece of sewing thread = Think hair strands

Hair Textures

  • Thready – This thready hair texture has a low sheen and a bright shine when the hair is stretched. This hair texture should have low frizz and get wet easily. Even though this hair texture wets easily, the water will dry out very quickly.
  • Wiry – This hair texture sparkly glossy appearance with very little shine and low frizz. When the wiry hair texture is wet, the water will bead up or bounce off the hair strands. This hair texture is more difficult to get fully wet.
  • Cottony – The cottony hair texture has low sheen, a bright shine when the hair is stretched and is usually is highly frizzy. The cottony texture absorbs water very quickly; however it doesn’t get completely wet very fast.
  • Spongy – The spongy hair texture absorbs water (like a sponge) and has a high sheen and low shine.
  • Silky – The silky texture has low sheen and a bright high shine. The level of expected frizz with this hair texture can vary substantially. Silky hair becomes completely wet very easy.

How to Find Your LOIS Hair Type

Examine a few of the most common types of hair on your head. If you have multiple hair types within the LOIS system, then you should begin by examining the most common hair type of your head.

Prior to examining your hair, be sure that it has been recently washed (rinsed in cold water) and doesn’t have any hair products applied to it.

Another option is to wash a strand of hair that has been removed from the scalp and rinse it in cold water. Allow the individual hair strand to dry without touching it to get an accurate depiction of the LOIS hair type.

Fia’s Hair Typing System

There is one other hair typing system that had a consistent following several years ago. Actually, there are still several women on some natural hair forums that are advocates for Fia’s Hair Typing System.

Fia’s Hair Typing System appears to expand on Andre Walker’s Hair Typing System and incorporate components of the LOIS Hair Typing System also. The system defines hair using three classifiers: (1) the definition of your curls (think Andre Walker), (2) the appearance of most of your hair strands, and (3) the overall volume of your hair.

First Classifier: The first classifier which defines your hair type by determining the curliness of your hair strands (or the lack thereof – if that’s the case) is analogous to Andre Walker system utilizing Type 1 – straight hair, Type 2 – wavy hair, Type 3 – curly hair and Type 4 – really curly hair.

Second Classifier: The second classifier focuses on the appearance of the majority of your hair strands. Actually, this classifier is very similar to the hair strand sizes used within the LOIS system, but there are some minor differences in terminology.

  • F – Fine: Fine, thin hair strands that feels almost like an ultra-fine strand of silk.
  • M – Medium: Medium sized hair strands, which generally feel like rolling a cotton thread between your thumb and index fingers, are ones that simply fall in between the fine and coarse categories according to Fia’s Hair Typing System.
  • C – Coarse: Think hair strands that feel hard and wiry.

 Third Classifier: The third classification of Fia’s Hair Typing System measures the overall volume of your hair. Simply place your hair in a ponytail. Include as much hair as possible in the ponytail. There is no need to worry too much about how your hair looks, because the goal is to have the majority of your hair included in the ponytail.

Once you have the majority of your hair in a ponytail, the next step is to measure the circumference of the ponytail. You can use a soft tape measure or another method that won’t damage your hair to measure the circumference of your ponytail.

Simply wrap the soft tape measure around your ponytail below the elastic (ex. Goody Ouchless Hair Elastics) used to hold the ponytail together.  The number shown on the soft tape measure is used to determine whether your hair fits into the thin, normal or thick according to Fia’s Hair Typing System.

  • Thin – The circumference of the ponytail is less than 2 inches (less than 5 centimeters)
  • Normal – The circumference of the ponytail is between 2 – 4 inches (between 5-10 centimeters)
  • Thick – The circumference of the ponytail is greater than 4 inches (greater than 10 centimeters)

Note: The circumference is simply the measured distance around a circle or edge of an object that is roughly circular.

Emerging Hair Typing Systems

There are other emerging hair typing systems, but honestly most of the new ones aren’t well known. If these emerging systems achieve an adequate social following, then I will update this article to include a complete discussion of those hair typing systems. At the moment, any hair typing system that doesn’t have a legitimate following within the natural hair community is considered outside of the scope of this guide.

Lately, many hair product manufacturers are creating proprietary hair typing systems in order to sell more hair products to individuals looking for personalization in their natural hair regimen. That said, several manufacturers have decided to use the very well-known Andre Walker Hair Typing System to recommend their products on a personalized basis.
