How Much Shampoo to Use?

Have you ever wondered how much shampoo to use? If you love your hair, you surely use a lot of hair products to keep your hair nourished and healthy. Even if you are not into using too many hair products, you surely wash your hair one or more times during the week. Keeping your hair clean is, no doubt, important. But what’s more important is gauging how much shampoo to use.

Studies suggest that most people aren’t aware of the exact amount of shampoo they need to cleanse their hair properly. They either use too little or too much of the shampoo and the results are often undesirable. When this happens, your hair takes a hit. If you are using less shampoo than what is required, your hair will remain dirty. Clogged pores, dandruff, hair fall, and scalp diseases will plague you throughout your lifetime. If you are dabbing too much shampoo onto your hair, it might feel dry and rough due to overwashing.

How to Decide How Much Shampoo to Use in Your Hair?

If your hair feels dry or dirty even after a wash, you need to watch out for the amount of shampoo that you use for each wash. The amount of shampoo that you should use for proper cleaning depends on a few factors that I will discuss here:

Hair Length:

This is the most important deciding factor. Someone with short hair will require much less shampoo than someone with knee-length hair. Ideally, if you have short hair, you should use shampoo about the size of a nickel. For someone with medium-length hair, a dollop about the size of a quarter should be ideal while people with long hair must use a dollop that’s as big as half a dollar.  So, to decide how much shampoo to use in your hair must first determine your hair length.

Hair Texture:

Your hair texture also decides how much shampoo to use. If you have fine hair, you will need a lot less shampoo than if you have coarse or rough hair. Find out the natural texture of your hair before you squeeze that shampoo bottle the next time.

Hair Density:

People with thin hair will need less shampoo than those with a thick mane of hair. The reason is simple. More hair strands require more shampoo for proper cleaning and less will need less. So, depending on the hair density, you will have to decide how much shampoo to use.

Hair Curl:

It has been found that people with straight hair require a lot less shampoo than people with wavy or curly hair. This is because the curlier the hair is, the more difficult it is to wash out the dirt and grime from the hair. This calls for more use of the shampoo and there’s nothing wrong with it.

Washing Frequency:

If you wash your hair frequently, you will need less shampoo per wash than if you wash your hair very rarely. The logic, here, is very simple. The longer the gap between two washes more is the dirt that accumulates on your hair and vice-versa. Naturally, you will need more shampoo with every wash to cleanse your hair properly.

Some Tips to Prevent Overusing your Shampoo

If you are using a fancy shampoo that has a high price tag, you wouldn’t want to use it more than you need. To prevent wastage, use the following tips:

  • Wet your hair very well before you apply shampoo. Mild warm water is perfect for a pre-shampoo wash. Wet or damp hair takes on the shampoo very well and prevents unnecessary use.
  • Squirt the shampoo onto your hand and then use it on your hair and scalp. Do not put it directly onto your scalp and hair as you will end up using more than what is necessary.
  • If you like a whole lot of lather, you will probably need a shampoo that contains sulfates. While sulfate-containing shampoos are sometimes harmful to hair, they create the best lather. If you want to avoid sulfates, you will have to settle with less lather. Using extra shampoo will not create the lather you are looking for and would be a total waste of your shampoo.
  • If you have long and/or textured hair, you may have to use shampoo twice every time to thoroughly clean your hair.
