Chapter 1: Introduction to Natural Solid Shampoo
Before we move on to choosing and using a solid shampoo, it is important to understand what this product is and why it deserves special attention. It is not just a “hair soap”, as it may seem at first glance. This is a whole world where science, nature and self-care come together in harmony. .
What it actually is: definition and principles
Solid natural shampoo is a concentrated product for cleansing hair and scalp, which comes in solid form (block, disc or tile) and is based on natural ingredients. Its main purpose is to effectively and gently cleanse both the hair and the environment. .
The main differences compared to regular products :
Compared to liquid shampoo :
Form and concentration :
Solid shampoo is essentially a concentrated version of liquid shampoo – just without the water, which makes up 80–90% of liquid shampoo. The result is a more powerful product that lasts longer. .
composition :
You will not find aggressive sulfates in natural solid shampoos. ( like SLS, SLES), parabens, silicones, synthetic fragrances and dyes – all common in the regular industry. Instead you will find gentle ingredients of plant origin: mild surfactants, oils, substances, plant extracts and essential oils. .
packing :
Most packaging is made of paper, cardboard, and sometimes the product is sold without packaging at all – in a “zero waste” format, which significantly reduces the use of plastic. .
Compared to regular hand or body soap :
Purpose and pH:
Regular soap is made by a saponification process with a strong base, so the pH level Its pH is high – usually between 8 and 10. This may be suitable for the skin of the body, but not for the hair. Alkaline pH damages the hair's protective layer, leaving it dry, dull and brittle, and can cause scalp irritation. .
composition :
A solid shampoo specially developed for the needs of hair and scalp. It includes ingredients that cleanse, soften, nourish and moisturize – all while taking the scalp into account. .
Pay attention :
Not every block labeled "natural" is truly so. Always read the ingredient list. If you recognize ingredients like PEG, sulfates, silicones ( for example Dimethicone, Cyclopentasiloxane), or mineral oils (Mineral Oil, Paraffinum Liquidum) – be careful. These are not compatible with the concept of natural care. .
Natural shampoo vs. synthetic shampoo based on surfactants (synthet) – what's the difference? ?
When choosing a solid shampoo, it is important to understand: not all shampoos are the same. There are two main types of products, which are sometimes confused with each other – but in fact they are completely different from each other in composition, manufacturing process and effect on the hair. If you are looking for a product that is truly natural, it is worth knowing the differences .
Solid natural shampoo (produced through a full saponification process)
What is this? :
This is a shampoo that is actually a natural soap specially developed for hair. It is produced through a saponification process. Saponification – a chemical reaction between natural vegetable oils (such as coconut, olive, castor, shea, etc.) and a base (NaOH or KOH). The result: soap (fatty acid salts) and glycerin – a natural moisturizer that is naturally obtained from the process. .
The main feature :
This shampoo is made "from the ground up" - without pre-prepared mixtures and without surfactants (synthetic or industrial). .
Composition and properties :
base : Saponified vegetable oils
Common additions :
Excess oils (superfat) – excess oils that soften the hair and scalp
Herbal infusions, herbs, essential oils, traditional powders (such as amla and shikakai), natural acids (such as citric or lactic acid)
pH – Why is it important? :
The scalp has a natural acidic environment. ( between 4.5 and 5.5) pH), which maintains the health of the skin and hair :
Maintains the natural protective barrier
Prevents the growth of harmful bacteria
Helps keep the hair cuticle closed and smooth
Reduces irritation, dryness and dandruff
Benefits of use :
No additional acid rinse required – pH level is balanced
Foams well – even in hard water
Provides a familiar feeling of use – the transition from liquid shampoo is easier and more pleasant
Shampoo based on surfactants (synthetics )
What is this? :
This is a shampoo made from surfactants. Surfactants – synthetic or semi-synthetic substances that foam and clean. Surfactants are common not only in solid shampoos, but also in facial soaps, gels, and more. .
Even if the surfactants (SFAs) are derived from plants, these types of shampoos are considered synthetic products. Such shampoos are called syndet (short for synthetic detergent ) . ).
The principle :
Instead of undergoing a natural saponification process, synthetic shampoos use pre-prepared detergents (PAS), to which oils, fragrances, active ingredients, and water are added. .
Composition and properties :
base : One type or combination of fashim, for example :
Sodium SCI Coco-Isthionate ) – delicate material)
Sodium SCS Coco sulfate ) – Stronger)
Coco-glucoside, lauryl-glucoside and others
Common additions : Oils, moisturizers, plant extracts, fragrances, preservatives
Acidic pH Mild or neutral (between 4.5 and 7) – matches the natural pH of the scalp
Why this isn't a "truly natural" shampoo ":
Syndicates are industrial products. Their cleaning base is not created by a natural process but by chemical synthesis, even if the ingredients are of plant origin. It is a stable, modern and convenient solution, but does not correspond to the classic definition of a completely natural or traditional product .
A historical glimpse: from ashes to modern solid shampoo
Hair care and cleansing have been with humanity for thousands of years. Humans have always sought to take care of themselves – and have used the resources available in nature in particularly creative ways. .
The ancient world
Various cultures have used natural ingredients for cleaning purposes. :
India : Soap plant powders (shikakai, aretha), amla, hibiscus
Egypt and Rome : Substances, herbal infusions, and ash rich in alkaline carbonates with cleansing properties
Europe : Germanic and Gallic tribes used mixtures of fat and wood ash to clean the head.
While these methods cleaned, they weren't always gentle or convenient for everyday use. .
The Middle Ages and Early Modern Times
Soap appears – a product of animal fat and ash (an alkali base). Soap becomes more common, but it is rarely used for hair. Most people make do with washing with rainwater or herbal infusions. .
Late 19th century – early 20th century
In the 1890s, German pharmacist Hans Schwarzkopf launched the first powdered shampoo – a product that had to be diluted with water before use. It was a revolutionary innovation, but the shampoo was still relatively harsh on the scalp. .
Mid-20th century
The era of liquid shampoos based on synthetic surfactants begins – such as SLS. These products provided impressive lather and strong cleansing, but also caused dryness, sensitivity, and damage to the hair texture, due to their chemical strength. .
Late 20th century – 21st century
Consumer awareness is growing. A clear trend change is developing. :
Back to sources : Natural shampoos based on soapy oils are returning to the shelves
Green chemistry : Shampoos with gentle plant-based surfactants are being developed – more effective, convenient and safer, and do not require an acidic rinse.
Rise of traffic Zero Waste: More and more people are choosing products that are not only natural in composition, but also plastic-free and environmentally friendly.
today
A modern solid shampoo is not just a “hair shampoo” – but a complete, advanced and effective solution, combining the power of nature with smart technology. It provides a real answer to diverse care needs, while maintaining a balance between body, hair and environment. .
Chapter 2: Why you should say “yes” to a natural solid shampoo ?
Switching from regular liquid shampoo to solid shampoo is not a trend – it is a conscious choice. It is a way to take care of your hair, the environment you live in and your daily comfort. So what are the benefits of a natural shampoo created through a soap making process “from the ground up”? "?
Benefits for hair and scalp – Back to nature
Gentle cleaning without aggression
Unlike industrial shampoos with sulfates ( like SLS and SLES), which can damage the skin's protective barrier, a natural soap shampoo maintains balance. The soap oils gently remove dirt, without drying or weakening the hair - a significant advantage for those with sensitive scalps. .
The vehicle is safe.
When you choose a solid natural shampoo, you avoid harmful ingredients like :
Acute sulfates (SLS, SLES)
Silicones (Dimethicone, Cyclomethicone) – “ seal” the hair and prevent proper breathing
Parabens – which are suspected of being substances that disrupt the hormonal system
Avoiding harmful substances
Solid natural shampoo does not contain :
Mineral oils (petroleum products)
Synthetic fragrances and dyes
Instead, you will find only natural ingredients. :
High-quality vegetable oils
Essential oils
Glycerin (naturally formed during the saponification process)
Herbal extracts
Positive effects with regular use
Less oily at the roots – The scalp maintains a natural balance and does not produce excess oil to compensate for dryness
Decrease in dandruff and itching – The gentle formula does not harm the scalp microbiome, and essential oils (such as tea tree) contribute to an antiseptic effect.
Strengthening the hair – Natural oils nourish hair roots, improve blood circulation and contribute to healthy growth
Natural shine and volume – After a period of adaptation, and with the help of occasional acid rinses, the hair becomes smooth, shiny and has presence.
Less irritation and redness – Especially important for those with sensitive skin or problematic scalps
Solid Natural Shampoo – A Truly Green Choice
Ecological packaging (Zero Waste)
Solid shampoos are often sold without plastic – wrapped in paper, cardboard, and sometimes even without packaging at all. This significantly reduces the amount of household waste. .
Fact: Over 400 million tons of plastic are produced each year – most of it in single-use packaging ( Source) (UNEP)
Less water – less ecological footprint
Liquid shampoo is made up of 80–90% water. Solid shampoo simply doesn’t need it – this saves a huge amount of water during production and transportation. .
Biodegradable
Natural oil-based shampoos are fully biodegradable and do not pollute water sources, unlike synthetic ingredients that can accumulate in ecosystems. .
Smart, economical and convenient – a choice that suits modern life
Prolonged use
A 50–100 g solid shampoo easily replaces 2–3 standard bottles (250 ml). Thanks to the high concentration, you use the product itself – not water. .
When stored properly (on a dry surface with drainage), such shampoo lasts 2–3 months or even more. .
Perfect for travel, lightweight and portable , not spilled, Is it allowed to take it on flights in hand luggage?
Summary
Switching to natural shampoo is an investment in your hair health, eco-friendly lifestyle, and personal comfort. It may take some time to get used to the shampoo that really works for you – but the results are worth every step of the way. .
How often should you shower? ?
Unlike aggressive shampoos, natural shampoo does not completely remove sebum (the scalp's natural oil), but gently cleanses only the excess. It preserves the natural protective layer, supports the balance of the microbiome and the skin's moisture level. .
If you regularly comb your hair and don't use styling products - one comb is definitely enough. .
When should you consider double overlap? ?
If a long time has passed since the previous overlap (7 days or more)
If you have used styling products, oils or dry shampoo
Bonus: You'll find that you overlap less
Many report that after a week or two of use, the hair is less oily at the roots and remains fresh for longer. The reason: Natural shampoo does not disrupt the activity of the sebaceous glands, so the skin stops "reacting" by producing increased sebum. .
The result ? Instead of washing your hair every day, you may be able to do it 1-2 times a week, without feeling heavy or greasy. .
Should I get used to natural shampoo? ?
No, hair doesn't "break down" – it just works differently.
Some people worry that their hair will look worse after switching to a natural shampoo. In reality, this rarely happens – and even then, it’s not because of the shampoo itself, but rather because of the cumulative effect of previous products. .
If you have previously used silicone masks, harsh shampoos or styling products, your scalp may need time to return to its natural balance. .
What may feel different at first ?
Hair is less "slick" " – This is normal: the silicones created an artificial layer that disappears
The instant shine is gone. – But after 2–5 uses, a natural, healthy shine appears
The hair "behaves differently" " – Less Paris, stays clean for a long time
This is not a worsening – but a return to normal. .
When is the result felt? ?
After 1–3 uses : Feeling of lightness, hair is clean and breathable
After 2–5 uses : The balance of oil in the scalp improves, the hair is full of volume and remains fresh for a long time.
In the long run
The benefits are cumulative – you forget about itching, sensitivity and daily shampooing. The scalp is calm, and the hair is balanced – both in terms of oiliness and appearance. .
How to make the transition easier ?
Use only natural products throughout your skincare routine – do not combine with industrial shampoos or silicone masks.
After the overlap , wash your hair with herbal infusion, diluted apple cider vinegar or use a natural solid conditioner
Choose a shampoo according to your scalp type , not by hair length
