Shampoo bar vs. hair soap – what’s the difference and what to choose?
At first glance, they look similar. Both come in the form of bars, produce foam and are used to wash hair. But that's where the similarities end. What's the real difference between a shampoo bar and a hair soap? And why is it so important when you want a healthy scalp and a smooth hairstyle?
Hair soap – a classic with an alkaline pH
Traditional hair soap has a simple composition: it's usually a mixture of fats and baking soda. It has a cleansing effect, but it has one drawback: its pH is alkaline (around 9-10).
What does this mean?
• May dry out the scalp
• Causes hair cuticles to open (frizz, roughness)
• Requires acidification, e.g. with a vinegar rinse
• Works well on short, strong hair or as a transitional product
Shampoo bar – modern care in its purest form
Shampoo bars aren't soap. They're a modern, concentrated form of traditional shampoo, only without the plastic and water.
What makes it stand out?
• It has a slightly acidic pH (approx. 5.5), close to the natural pH of the skin
• Contains gentle detergents (e.g. SCI, Coco Glucoside) that foam well and do not irritate
• No rinsing required
• It is a full-fledged shampoo without any weight or compromises
For whom what?
• Hair soap: for fans of minimalism, short hairstyles, and people with a neutral approach to the visual effect
• Shampoo bar: for anyone who expects the effect of a professional shampoo: lightness, shine, volume and easy combing
