Thick vs. thin hair – How do you know which type you have? Does it refer to the total girth, or is it about how thick or thin a single strand of your hair is? Well, it is the latter. This article lists out all the differences between thick hair and thin hair, along with a few useful hair hacks to thin out thick hair and vice versa. Read on to know more!

What Is Thick Hair?

Hair thickness indicates the width of a single hair strand. People often confuse thick hair with a density of hair. Hair density is a measure of the number of hair strands per square inch of the scalp.

What Is Thin Hair?

If the hair thickness is lesser than the width of a thread, it is referred to as thin hair.

How To Measure Hair Thickness

1. Strand Test

This simple method may help you analyze the thickness of your hair easily at home. All you need is a hair strand.

  • Pluck a single hair strand and hold it in between your fingers.
  • If you cannot feel the hair, and it is not visible to the naked eye, it is thin.
  • If you can feel it a little, it is medium hair.
  • If you feel it is grainy and strong, your hair texture is thick.

  • If your hair is slimmer than the thread, it is thin hair.
  • If it matches the thickness of the thread, it is medium hair.
  • If the hair thickness is more than the thickness of the thread, you have thick hair.

Difference Between Thin And Fine Hair

If your mane has less volume and the hair follicles are far apart, your hair looks thin.

‘Fine’refers to the width or diameter of a single hair strand. Fine hair is smooth and silky, but it might not always mean that the hair follicles are far apart. This hair type is lightweight and prone to breakage.

For better understanding, we have discussed the term ‘low-density hair’ and ‘high-density hair’ in the following section.

Low-Density Hair Vs. High-Density Hair

Low-density hair means the number of hair strands on your scalp is lesser than normal. The hair strands are fragile, and your scalp is visible. It is difficult to style low-density hair and get a voluminous look.

High-density hair means the number of hair strands on your scalp is high. This hair type tends to tangle more but looks voluminous and is easy to style.

Whether you have thick or thin hair, you might face some issues with hairstyles. Check the following section to know what they are.

Thick And Thin Hair Problems

  • If you have thin hair you will find it difficult to tie a ponytail. The clips and rubber bands tend to slip because of the smooth texture of thin hair. Your tresses might not hold any curls and look limp or greasy without a good conditioner or hair mask.
  • If you have thick hair, it is prone to tangles and takes up a long time to blowdry. You need big hair accessories to tie thick hair properly. It takes a lot of time to dry damp, thick hair, and it might feel wet throughout the day.

Manisha, a YouTube vlogger, shared her thick hair problems and explained how difficult it is for her to try different hairstyles. In her vlog, she says, “I can not tell you how many hours I am wasted and being late to try all these hairstyles. It’s about five of them for an hour, realizing none of them work (i).”

  • Choose a hair treatment for your thick hair. Apply a deep moisturizing hair mask or spa treatment cream to control the volume and impart a shiny, smooth look to your cuticles.
  • Use a smoothening shampoo and conditioner to make your hair visibly thin.
  • Rinse your hair with cold water. Washing the hair with hot water strips essential oils from the scalp, making the locks dry and frizzy.
  • Apply hair cream or serum before blow drying. This will weigh the hair down without making it greasy.
  • Try a flat iron for a smooth and sleek look.

Our hair changes as we age and you can also change the texture with chemical treatments. However, if you wonder if is it possible to change the hair type permanently, we have the answer in the next section.

Can You Change Your Hair Type?

The instant response would be no. However, hair type can be subtly transformed using minoxidil if your aim is to change it from thin to thick. According to anecdotal evidence, this common medication used for managing hair thinning and hair loss can improve the density of the hair as well. You can also try changing your shampoo and look for the ones that can help you achieve your desired hair type. For instance, keratin shampoos are ideal for individuals with thick hair as they can aid in combating frizz, while biotin or argan oil-based shampoos promote thickness and tackle thinning strands.
