Sulfate-free dog shampoo: myth or true necessity?
Partager
"Sulfate-free" has become a key marketing argument for human shampoos. It's now starting to flood the canine market. But what does it really mean — and does your dog need it?
What are sulfates in shampoo?
Sulfates (SLS — Sodium Lauryl Sulfate — and SLES — Sodium Laureth Sulfate) are surfactant cleansing agents. They effectively degrease the coat and create lather. SLS is more irritating; SLES is generally better tolerated.
Does a "sulfate-free" shampoo really clean?
Yes, but less effectively on very greasy or very dirty coats. Sulfate-free formulas use alternative surfactants (glucosides, betaines) which are milder but also less degreasing. For an active herding dog coming back from the forest, this may not be optimal.
The true enemy of dog skin: fragrance, not sulfate
Veterinary dermatological studies show that allergic reactions and irritations are much more often due to fragrances and preservatives than to cleansing agents. A shampoo with SLES but without fragrance will often be better tolerated than a sulfate-free shampoo loaded with perfumed essential oils.
What Gust Care's INCI says
Our shampoo contains Sodium Laureth Sulfate (SLES) — not SLS. We don't claim to be "sulfate-free." However, we are fragrance-free, dye-free, and pH-balanced. That's where the real protection for your dog's skin lies.
