Sulfates (SLS/SLES)
The harsh detergents in cheap shampoo — why 'sulfate-free' matters for skin, hair, and color-treated beards.
Sulfates (sodium lauryl sulfate and sodium laureth sulfate) are the aggressive foaming agents in most drugstore shampoos. They clean effectively but strip sebum, disrupt the acid mantle, and irritate sensitive skin. Sulfate-free formulations use gentler surfactants — the standard in every Grizzly wash product.
- ›SLS and SLES are the two main sulfate detergents.
- ›Strip natural sebum from hair and skin.
- ›Fade color-treated hair and beards faster.
- ›Sulfate-free surfactants clean without stripping.
- ›All Grizzly wash products are sulfate-free.

History & Origin
Sodium lauryl sulfate and sodium laureth sulfate became the dominant cleansing surfactants after the Second World War because they are cheap, foam abundantly, and clean almost anything. Their reputation problem started in the 1990s with internet claims about toxicity that regulators have not supported — the real issue is far more mundane: they clean too well for coarse hair and facial skin.
Uses & Benefits
- ›Strong anionic surfactants that produce dense, satisfying foam
- ›Remove sebum aggressively, which is why they excel on greasy scalps and hands
- ›SLS is harsher than the ethoxylated SLES
- ›Can leave coarse beard hair brittle and skin tight when used frequently
- ›Still appropriate in some body and hand products where deep cleansing is the point
Safety & Sourcing
Sulfates are not carcinogenic — that claim has been repeatedly reviewed and rejected by regulatory bodies. They are, however, genuine irritants at high concentration and with frequent use, particularly on facial skin and coarse hair. If your beard feels like wire after washing, the surfactant is the likely culprit.
FAQ
Are sulfates dangerous?+
No. The toxicity claims are not supported. They are irritating for many people with frequent use, which is a comfort issue, not a safety one.
Why avoid sulfates on a beard?+
Beard hair is coarse and dry, and the skin beneath is facial skin. Aggressive degreasing leaves both brittle and itchy.
Is SLES gentler than SLS?+
Generally yes, though both are strong compared with the mild surfactants used in beard washes.
