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.

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.

Difference Between Thin And Fine Hair

If your hair 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 hair 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.

Check out the next section for some hacks to make your thin hair look voluminous.

How To Get A Thick Hair When It Is Thin

  • Trim your hair short to create the illusion of thicker-looking hair. Chop a few inches at the tip and add some layers for a voluminous look.
  • A volumizing shampoo helps add body to your limp, thin hair.
  • Blow dry your hair with volumizing styling products. Use a lightweight mousse to achieve a long-lasting bouncy look.
  • Use the right kind of hairbrush to help boost the hair volume. Brushes made of boar bristles are gentle on the scalp and add volume to thin hair.
  • Spray a dry shampoo on the roots of your hair to cleanse your locks and add volume without making your hair greasy.
  • Tie your thin hair in a double ponytail to make it look voluminous.

How To Thin Out Thick Hair
