The most common question I've heard lately.

At once I want to tell that at us on sale only firm shampoos.
❌ Shampoo soap - not made.

What is the difference between these two hair products?
❗️hard shampoo is made by a completely different technology. It does not contain alkalis (alkali-Russian).
❗️ solid shampoo always has a smaller volume, because it lasts a long time, no need to make bars of 100-150 g
❗️ is not used to solid shampoo, and hair should get used to shampoo soap within 1-2 months
Solid shampoo has a much lower pH level
Hard shampoo is always more expensive than shampoo soap
❗️hard shampoo washes much harder, the foam is thicker
❗️ Solid shampoo has a porous surface. It cannot be smooth and shiny. It is because of the manufacturing technology
❗️ Solid shampoo contains many more useful ingredients, such as panthenol, keratin, wheat protein

I do not want to say that something is better, something is worse. Everyone chooses a product for themselves. Which will suit you.
