Another day, another beauty buzz-phrase – but what does “sulphate-free” actually mean? We’re forever trying to perfect our hair routine, and so, it’s only right that in the pursuit of the most luscious locks, we investigate the benefits of sulphate-free shampoo to help you decide whether to switch up your hair care arsenal.
What are sulphates?
“Sulphates are detergents used as a cleaning agent in shampoo as well as many types of cleansing products,” Kieran explains.
“They are most commonly known for their lathering ability, but the downside is that they can be too good at cleaning, stripping away the natural moisture from the hair and scalp causing dehydration, colour fade and scalp irritation.”
What are the hair benefits of using sulphate-free shampoo?
“Providing the sulphate-free shampoo is formulated using more gentle cleansing agents, the main benefits are that your hair will be less dehydrated, retaining its natural lipids with more shine and vitality.”
Which hair types are most suited to sulphate-free shampoo?
“I think all hair can benefit from sulphate-free shampoo. That is not to say that there isn’t a use for sulphates, but like all things, it’s about using them for their purpose. For example, people may need to use a clarifying shampoo from time to time, especially if their hair is oily.”
Can you use sulphate-free shampoo on hair extensions?
“Yes absolutely, sulphate-free shampoos are generally gentler, and so would be ideal for protecting the extension bonds and keeping the hair hydrated.”
How can I tell if my shampoo is sulphate-free?
If it doesn’t say so on the outside of the bottle, check out the ingredient list. Look out for the mention of sodium lauryl sulphate – also known as SLS – and sodium laureth ether sulphate (SLES).
In terms of performance, Kieran explains: “One of the tell-tale signs of sulphate-free shampoo used to be that they didn’t lather up as well, however formulations have improved, so that they now can create a rich lather. Centred’s Daily Calma and Heightened shampoos use a coconut-derived cleansing agent which produces a really luxurious lather.”
