What Is 1A Hair

What’s my hair type?


Hair “types” became popular in the 1990’s when a well-known American hair stylist Andre Walker, created the classification of human hair into 12 different types which today is called as the Andre Walker Scale or more commonly known as the Hair Chart.

Well, earlier hair types were just generalized as straight, wavy or curly hair, but as per the hair chart, you will get to know the extent of how straight or curly your hair actually is. Pretty cool, right?

So the 12 hair types are numbered from 1 to 4 (to know your hair’s texture), each number consisting of 3 alphabets – A, B and C (to know the shape of the hair strand).

In short, hair type 1 is straight hair, hair type 2 is wavy hair, hair type 3 is curly hair and hair type 4 is coily or kinky hair.

What may be hard here is to know whether your “straight” hair comes under the 1A, 1B or 1C category, so here are the details.

How To Identify 1a Hair

The 1A hair type is basically the straightest hair can get out there. It is absolutely straight and is extremely fine in texture and very thin in size. 

One of the biggest disadvantages of this hair type is how easily it breaks because the hair is very fine and fragile. 

Also, most often, even when styling this hair type to get waves or curls, most often the hairstyle doesn’t hold for a very long time unless it is permanent.

Distinctive characteristics of the 1A hair type

  • Very fine in texture.
  • Stands very flat and looks limp and weighed down.
  • Each hair strand is very thin in diameter.
  • Prone to easy breakage because the hair strand is super fragile.
  • Hairstyles do not hold for a long time.
  • Hair doesn’t have any volume and body.

Differences between 1A, 1B and 1C Hair


Very often people with the 1A hair type, often confuse their hair with the 1C hair type and this is because the 1A and 1C hair types are rather similar in terms of how straight the hair strands are, but only vary in terms of hair thickness, where the 1C hair strands are way coarser than the 1A hair strands.

When it comes to the 1B hair type, the strands are just relatively straight, but have very subtle bends along the length of the hair, making it easier to differentiate as compared to the 1A and 1C hair types.

Tips to Deal with 1A Hair

1. Use the right products to add hair volume

Whenever you are using products like shampoos, conditioners, hair oils and moisturizers, make sure to use ones that are specifically designed for use on “fine” or “thin” hair.

You always need to look out for products that are lightweight, be it oils or moisturizing creams. 

The reason lightweight products need to be used on fine and thin hair is because the 1A hair type is already prone to standing dull and limp and most often looks very flat and weighed down. 

This hair type has no volume or bounce. Therefore, using a lightweight product will not further weigh down the hair when used.

You can also look out for hair volumizing products that can help give your fine hair a natural bounce.

2. Use the right technique to brush your hair and get rid of tangles

It is not too often that fine hair gets tangled up, but yes there are some pesky tangles that show up sometimes and need to be taken care of. Well, the best way to get rid of tangles is by using a pin hair brush. 

Make sure to start with detangling your hair from the bottom and gently holding onto your hair, working your way to the top.

Using this method to detangle 1A hair (or any hair type in general) is very  important because 1A hair is extremely prone to breakage and even a little tugging on the hair strand can cause it damage.

3. Wash your hair regularly

Our scalps have natural oils called sebum. This is what keeps our hair moisturized.

And as 1A hair is fine, straight and thin, this natural hair oil flows down along the length of the strand very easily making the hair look very oily and greasy, even though it may have been just washed.

Therefore, for those with 1A hair, it is important that you should wash your hair at least three times a week or once every alternate day.

Here’s a tip, you can stick to conditioning your hair every two hair washes with shampoo. This is because 1A hair is sufficiently moisturized with the hair’s natural oil (sebum) and therefore doesn’t require external conditioning too often.

Make sure not to over-wash your hair, as this will stimulate the sebaceous glands and accelerate the sebum production making the hair super oily in no time. So a moderate amount of washing is ideal.

4. Get yourself a volumizing haircut

Since 1A hair is very thin and fine, it often looks flat and lacks volume. Therefore, one of the best ways to make the 1A hair type look voluminous, apart from using volumizing creams and serums, is by getting a volumizing haircut.

A “volumizing haircut” for 1A hair is simply getting layers. Yes, the more number of layers you get, the more “voluminous” your hair will look.

Some people also go in for asymmetrical and bob haircuts because they give the hair an illusion of looking thicker and bouncier.

5. Avoid the use of heat styling tools

Heat is bad for any hair type in general, but is one of the worst things for 1A hair. 

This is because 1A hair is prone to breakage because it is very fragile and using heat on the hair will make the hair dry out easily and succumb to hair damage like breakage and split ends in no time.

6. Dry your hair naturally and avoid using blow dryers

Blow dryers also come under heat styling tools for the hair and therefore must be avoided as far as possible. 

One of the best ways out is by pat drying your hair using a microfiber towel so that all the excess water can be got rid of and then let your hair air dry naturally.

Using a microfiber towel will help not only dry your hair quicker, but will also lessen the damage caused to your hair, as it will not tug on your hair strands.

7. Make sure never to sleep with wet hair

A lot of people often wash their hair just before they go to bed. This means that they go to bed when their hair is still wet or maybe, damp. 

Either way, sleeping with wet or even damp hair can be detrimental to the hair because the hair strands are at their weakest when it is wet and can break off very easily.

Also, if you sleep while your hair is still wet or damp, it will result in your hair becoming very frizzy.

8. Make use of dry shampoos between washes

Since the 1A hair type is prone to getting oily and greasy very quickly and tends to look flat and stands very limp in no time, dry shampoos can come to your rescue. 

Well, since overwashing your hair is no solution to getting rid of the oily texture and hair greasiness, the best way to go longer between washes is by using a dry shampoo on your hair. 

It will help absorb some of the excess oil and make your hair look less oily and stand better and less limp.

How Rare Is 1a Hair

Have you ever heard of 1a hair? It’s a type of hair texture that’s not commonly talked about. In fact, it’s considered to be the rarest hair type of all. 1a hair is characterized by being very straight and fine. It tends to be very low in density and lacks volume or body.

The hair is so straight that it often doesn’t hold a curl very well, and it’s also very slick and shiny. While this hair type may seem low maintenance, it actually requires a lot of care to avoid damage. According to experts, only around 2% of the population has 1a hair, making it the rarest hair type.

This means that it’s not often represented in the media or even recognized by some people. Many women with 1a hair may struggle to find products that work for them, as most hair care products are formulated for thicker, coarser hair types.

Despite being rare, 1a hair can be beautiful and striking. It’s important to embrace and care for your hair type, no matter how different it may be.

With proper care and styling techniques, those with 1a hair can achieve a healthy and gorgeous look that highlights their unique beauty. Don’t underestimate the power of 1a hair! It’s a rare and special hair type that deserves recognition and appreciation.

Do I Need Straightening Shampoo For 1a Hair

When it comes to hair, one size definitely does not fit all. Hair types can range from thick and curly to fine and straight, and knowing your specific hair type is key to maintaining healthy locks. If you have 1a hair, you may be wondering if you need a straightening shampoo to keep your hair looking its best.

First, let’s define 1a hair. This hair type is characterized by being fine and straight, with little to no curl or wave. Essentially, it’s the straightest hair type there is. Because of its straightness, 1a hair can become easily weighed down and greasy, making it important to choose the right shampoo for your specific needs.

While there are many different types of shampoos available, including those designed specifically for straightening, they may not necessarily be the right fit for someone with 1a hair. Straightening shampoos are typically designed for those with frizzy or wavy hair, helping to smooth out the hair and reduce frizz.

Because 1a hair is already naturally straight, using a straightening shampoo may not have any added benefits. Instead, those with 1a hair should look for shampoos that are lightweight and volumizing. These types of shampoos can help to add body to the hair without weighing it down.

Additionally, those with 1a hair may want to consider using a dry shampoo in between washes to help combat any excess oil or greasiness.

Is it true that my 1A hair texture can change over the years?

Yes, it most definitely is true. Hair textures can go from straight to curly over the years or can even change from thin to thicker over time and this can be due to various factors like hormonal changes like puberty, pregnancy etc, type of hairstyles like braids, ponytails etc and oil massaging of the scalp which can contribute to increasing the thickness of the hair over time.


The final takeaway

Well, the 1A hair type is known to be one of the most uncommon hair types to have. 

So if you are one of those people who have the 1A hair type, make sure to follow the right hair care routine to make sure to keep your hair well-maintained and healthy at all times. 

Since your hair is super fine and thin and prone to easy breakage, make sure to give your hair the extra care it needs.
