Sulfate-free shampoo is a type of unsalted shampoo that does not lather in the hair, and is good for dry, brittle or brittle hair because it does not attack hair as much as a regular shampoo.
Sulfate, which is actually sodium lauryl sulfate, is a type of salt added in the shampoo that helps clean the wires and scalp more deeply by removing its natural oils. A good way to know the shampoo has sulfate is to read in its ingredients the name sodium lauryl sulfate.
All common shampoos contain this type of salt in their composition and therefore make a lot of foam. The foam is not harmful to the hair but is an indication that the product contains sulfate, so the more foam it makes, the more sulfate it has.
What is sulfate-free shampoo?
Sulfate-free shampoo does not dry out hair and is therefore particularly suitable for people with dry or dry hair, especially for those with curly or curly hair, because the tendency is to be naturally drier.
Non-sulphate shampoo is particularly suitable for people who have curly, dry or chemically treated hair with smoothing, progressive brush or tinctures, for example. In this case the hair becomes more fragile and brittle, and needs more wetting. Whenever the hair is under these conditions one should opt for sulfate-free shampoo.
What is the difference between shampoo without salt and shampoo without sulfate
Unsalted shampoo and non-sulfated shampoo is not exactly the same because although these two substances are salts that the cosmetic industry adds to the shampoo, they have different functions.
The non-salt shampoo refers to the removal of sodium chloride from its composition, which is good for those who have dry or dry hair because it leaves the hair dry and cause irritation or scaling on the scalp mainly of having fine hair, curly or curly. Already the shampoo without sodium lauryl sulfate, is another type of salt present in the shampoo, which also dries the wires.
Therefore, anyone who has thin, brittle, brittle, dull or dry hair can choose to buy unsalted shampoo or sulfate-free shampoo because it will have benefits.
