Why You Should Use Sulfate-Free Shampoo
If you haven’t already switched to sulfate-free haircare (you probably will after reading this), take a look at the ingredients on the back of your shampoo bottle. You might be surprised to see some of the most harmful ones right at the top.

Common Sulfates Found in Shampoo
- Sodium Lauryl Sulfate (SLS)
- Sodium Laureth Sulfate (SLES)
- Ammonium Lauryl Sulfate (ALS)
Sulfate-free shampoos may foam less, but that’s a good thing. Sulfates are harsh detergents that strip away all the natural oils from your hair and scalp, leaving them dry and brittle. This can result in frizz, irritation, or even skin conditions like eczema.
Why Sulfates Are Harmful
Using shampoos with sulfates has been linked to the following issues:
- Scalp irritation and dryness
- Hair follicle damage and slowed growth
- Hair thinning and breakage
- Increased risk of skin absorption of toxic chemicals
- Potential links to hormonal disruption and organ toxicity
Who Should Avoid Sulfates?
Everyone can benefit from using gentler, sulfate-free hair products, but it’s especially important for people with:
- Coloured or chemically treated hair
- Keratin treatments
- Hair extensions (especially bonded or tape-in)
- Sensitive or oily scalps
- Dry, brittle or damaged hair
Reminder: Sulfates can break down extension bonds and strip colour, shortening the life of your investment.
