The impact of liquid shampoo bottles

There are many concerns with the use of conventional shampoos. Many contain chemicals which are bad for both people and the planet. 

Harmful to the environment

  • Pollutes Waterways: Many mass produced store-bought shampoos have harmful chemicals in them. When you rinse your hair, the chemicals go down the drain and water supply.
  • Dangerous for aquatic life: Studies have found some chemicals found in personal care products can change the hormone levels in marine organisms. This can cause a variety of health problems for them.
  • Plastic Packaging: Shampoo companies often use non-recyclable plastic bottles to hold their products. These end up on our beaches and landfills.
  • Watered down: Liquid shampoo contains a lot of water which means they are not very concentrated and you have to use more of the product to get the desired result. This means more plastic waste and also more costly for consumers. 

Harmful to your hair and skin

Some liquid shampoos can strip your hair of natural oils, so you have to buy a separate conditioner to make your hair smooth.

The synthetic ingredients found in most commercial hair care products are not suitable for most hair types. Some of the common ingredients to avoid are-

  1. Perfumes/ Fragrances: Many companies use "fragrances" to hide harmful chemicals. Artificial scents can lead to indoor air pollution and health problems like asthma, rashes, skin irritation etc. 
  2. Parabens: It is best to switch to shampoo without parabens. Parabens are chemicals that are used to keep shampoo from going bad. Studies have shown that they disrupt hormones in the body creating negative health outcomes. 
  3. Sulfates: Sulfates are chemicals used to clean the dirt and extra oil on your scalp. They also help shampoo to lather, however they leave your scalp dry and lead to frizzy hair. 
  4. Phthalates: They help the product spread more easily and make the perfume stick to your scalp and hair. Phthalates have been related to causing hormonal imbalance in the body. 

What is a shampoo bar?

A shampoo bar is a block of soap specially formulated for cleaning your hair. As the name suggests, they are different from bottled shampoo. The great thing about them is that they can be used as a cleansing and conditioning product. Not only are you getting a concentrated product with no plastic packaging, it lasts longer and eliminates the need for conditioners. 

What makes a shampoo bar better than liquid shampoo?

Liquid shampoo bottles are notorious for filling up our landfill and containing harmful fillers and additives. So, what are the advantages of switching to a shampoo bar? There are many reasons why changing to a shampoo bar is the more sustainable choice for your hair care routine.

  • Saves Money: Hair soaps last longer than their liquid counterparts. They are highly concentrated and you only need to use a tiny bit each time to create a generous lather.  How long it will last will depend how often you wash your hair. On average, you can expect around 60-80 washes for an average size 100g bar. Moreover, as organic hair soaps are made of a blend of different oils, they nourish hair rather than striping it, which eliminates the need for a conditioner bar.
  • Travel Friendly: You can find many shampoo bars in tin. They are easy to carry while travelling and are solid which means they are also leakproof! You don't need to play Tetras with all your toiletries as they take up hardly any space in your bag, you can also cut the bar and take a small piece with you so you don't have any waste. 
  • Cleanse & Condition: Shampoo blocks effectively clean residue build-ups. The nourishing oils in natural soap bars moisturise dry or itchy scalps. You can use just one eco soap bar for both your needs! 

How well do shampoo bars work?

Are all-natural shampoo bars good for you? Natural shampooing bars are long-lasting and hypoallergenic. You need to rub the bar on your wet scalp and wash your hair as you usually would. You will notice frizz-free hair after two to three washes.

The best part is that the essential oils of these bars deeply nourish all hair types- straight, thin, curly, coloured- you name it! 

There are many different types of bars available to suit all hair types and just like regular shampoo you may need to try a few before you find the right fit for your hair type. 

Can you use a shampoo bar every day?

The Short Answer: It is up to you. However, it is recommended that you only wash your hair every 2 - 3 days. 

The Long Answer: Every individual has different needs. The best hair care ritual is the one that feels right to you. There are many opinions on how much one should shampoo their hair. Let us look at some of the points that will help you decide what works for you. 

  • Hair Length: If you have long hair, it can be a hassle to wash it daily. Short hair is easy to maintain and can be cleaned with or without soap every day. 
  • Hair Type: People with curly hair can experience frizziness when they wash their hair daily. It is best to wash your hair every three to four days in that case to keep the natural oils. Similarly, people with oily hair can wash their hair whenever it starts feeling heavy. 
  • Type of Shampoo Bar: Many hair wash bars are made to treat specific conditions like dandruff, itchiness, etc. It is not recommended to use such bars every other day. Excessive use can strip your hair of its natural pH balance.
