The Complete Guide To Shampoo Bars

Selecting A Shampoo Bar

Commercial shampoos are among the most controversial cosmetic products. It contains far many sulphates and silicones or polymers (pollutants that are a little bit stuffy for the texture of the hair). In addition, a commercial shampoo uses a lot of water, and a plastic bottle that will have to be thrown away. The ecological impact is therefore not at all neutral.

Shampoo Bar is a cosmetic that comes in different forms that resemble a bar of soap. Solid shampoo is an environment friendly option and offers various fragrances like; Lavender, Jasmine, Coconut, Lemon, Mint, etc. they will leave you with a rich aroma and with soft and shiny hair.

Have you ever wondered how many shampoo containers do you use per year? It is estimated that every minute, one million plastic bottles are sold around the world, of which 93% will end up in the ocean or in a dump. Therefore, stopping the use of plastic packaging can be very helpful to our environment.

Therefore, the shampoo in bar has become very popular in recent years; mainly because:

1. The shampoo in bar, being solid, does not require packaging so you do not generate waste
2. It is easy to transport without spills
3. It is 100% natural
4. You can prepare it at home
5. You can adjust the ingredients to have the aroma you want for your hair, or even the nutrients you want

We recommend being patient and waiting 2 weeks until your hair gets used to the 100% natural bar shampoo to experience all the benefits that will bring to your hair health.

Ingredients In A Shampoo Bar

PURC shampoo bars and conditioner are natural, eco friendly and are not tested on animals. In addition, we do not use water, we use aloe vera juice or hydrolates (floral water), natural essences and cocoa butter or copoazu. We don’t use synthetic perfumes or glycerin.

How To Use Shampoo And Conditioner Bars

You have two options to use them, the first and most practical is to wet your hair and then you must rub the shampoo bar on your scalp. The second is to moisten your hair and then rub the shampoo between your hands, once you have the foam, you must pass it all over your head. After this, you should rinse thoroughly.

To use the conditioner, you just have to rub it on your hair, from half to ends. Leave it on for a few minutes and then rinse it off. Store your bars in a clean and dry place, it will not only last longer, you only have to rub the shampoo and conditioner two or three times, that will be enough for you to get foam and leave your scalp squeaky clean.

How Long Do Our Shampoo And Conditioner Last

It depends on the length of your hair, but it can last on average from one month or up to three months. The bars are more concentrated than traditional shampoos and conditioners, so you can use less per application and they will last longer.

This is especially true with proper care (do not let your bars soak in water).

Why do they last longer? Take a look at a bottle of shampoo or conditioner in the shower or on store shelves and the first ingredient you’ll see is water. This explains why you normally need a healthy amount of products to get the performance you want. It’s true, most bottles only recommend using a minimum amount, but how many of us tend to use a little more than that? With the bars, it is much harder to use too much, especially when you apply the bars directly to the head. With shampoo bars, you will find that they become suds immediately, so you can say very quickly when you have reached the desired foam.

Shampoo bars are ideal for traveling since you don’t have to worry about possible spills or liquid restrictions. The bars are perfect to carry since they are not only small and light, but they are approved by customs at airports and train stations, which means you don’t have to plan the packaging of your hair care products!  And best of all, they help prevent the use of individual-sized shampoos and conditioners in your hotel, which goes back to point on reducing packaging waste.

Shampoo bars are excellent for saving space. Being much smaller and lighter than its bottled counterparts in relation to the amount of washes you can get from the same amount of product, shampoo bars help save space. This is useful in a variety of situations, from keeping your bathroom cabinets organized, to packing for an upcoming trip.

The bars help create a minimal aesthetic in the shower / bath by reducing the messy appearance of the bottles. Most importantly, the carbon footprint in general is smaller with shampoo bars. As mentioned, these solid bars are lighter and more compact than their bottled counterparts, so they require less space during transport in relation to the same amount of liquid shampooing. Approximately ten to fifteen liquid shampoo transport trucks would be necessary to obtain the same number of washes as with a solid shampoo bar transport truck.

For any type of hair. But for long hair or slightly oily hair our solid shampoo is perfect! It is also 100% natural, without silicones, without sulfates and without parabens. Vegan and not tested on animals. The bars weigh around 100g (about 70 to 80 uses). 

With our solid shampoo, washing your hair once is usually enough. But if you want, you can repeat the steps for a second application, or wash your hair with our solid conditioner.

Steps To Make Your Own Shampoo Bar

To make solid shampoo you need to create a mixture composed of solution of alkaline salts (sodium hydroxide), water and oils; that is, follow a procedure similar to that of a bar of soap.

Each oil has different benefits when making solid shampoo. For example, coconut oil makes a hard bar and has cleaning properties, while olive oil makes a softer bar, with moisturizing benefits.

To make an easy recipe for homemade and organic solid shampoo, here we simplify the amounts you will need.

It is very important that you wear gloves and goggles, and cover work surfaces. Be very careful when mixing sodium hydroxide and water, as vapors can cause a choking sensation in the throat. This will decrease after a minute or so.


2/3 cup olive oil
2/3 cup coconut oil
2/3 cup sweet almond oil
3/4 cup distilled cold water
1/4 cup 100% sodium hydroxide
2 tablespoons of essential oils of your choice


Have everything ready before you start. Some of the steps have to be carried out quickly.

1. Mix the first three oils in a large glass or stainless steel bowl. If any oil is in solid presentation, melt it before measuring the amount you need.

2. Measure the water in a glass or stainless steel container. Be sure to use a heat-resistant container when making the mixture, since the exothermic reaction when sodium hydroxide is added can cause heat of around 93°C.

3. Measure the amount of sodium hydroxide, and make sure you have exactly one quarter cup. Have a spoon ready and stir with it while slowly pouring sodium hydroxide into the water. You have to add sodium hydroxide to water, NEVER backwards.

Continue stirring until mixture begins to become clear. Avoid fumes while doing it. Allow the mixture to cool to approximately 50°C.

4. Heat the oil mixture and when it is at 23°C and slowly pour the sodium hydroxide mixed with the water into the oils, mix everything.

5. For the next 5 minutes, do not stop mixing by hand. This will allow as many oil molecules to come in contact with as much sodium hydroxide as possible. After 5 minutes, use a hand mixer to mix, being careful not to introduce air. Mix until the mixture is thick.

6. When it has reached the thickness, you can add an extra tablespoon of another oil. This extra oil will add additional moisture to your homemade shampoo bar. You can also add optional essential oils at this point. Stir well to mix them.

7. Pour the soap mixture into molds and cover with plastic. After 24 hours, place them on parchment paper or on a baking rack. Leave them in a dry place and rotate them once a week approximately (which is not necessary if you use a baking rack).

The homemade and organic solid shampoo can be used after curing for 4 weeks and the bars will be softer the longer they are allowed to cure.

Tip: If you want to add color, buy a natural dye and add a few drops during a water bath.
