Shampoos FAQs

What is sulphate-free shampoo?

Yep, you guessed it – a sulphate-free shampoo is a formula that banishes the likes of those nasty suds that can aggravate both the skin and hair. Sulphates are the ingredients that are responsible for that lathering, foamy action that shampoos produce when rubbed in. They are a surfactant (a foaming agent) that attracts both oil and water, lifting that dirt and oil build-up from you scalp and hair for a thorough wash. While this sounds like a good action, it can also be quite damaging as the surfactant strips away the naturally occurring, healthy oils from the scalp and hair, which can often lead to a dry scalp or dandruff.

A sulphate-free shampoo can still lift away the bad dirt and oils, but it will not strip away the essential oils your scalp needs to maintain a healthy functionality – it will just require a more rigorous massage on the scalp in order for it to work. Now, that's not a huge price to pay for healthier hair!

How do I use shampoo?

Most shampoos follow the same process: wetting the hair, applying a palm-size amount of shampoo and lathering up! Pretty simple really. However, it is so important to really wet the hair before application for a good lather, as well as a thorough rinse once the shampoo has been applied to ensure your scalp isn't left feeling irritated.

It is advisable to follow up with a conditioner to ensure that hair remains strong, healthy and hydrated for the shiny results you deserve.

What is a shampoo bar?

Arriving in a similar form as the common bar of soap, a shampoo bar is exactly what it says it is – a shampoo formula in a solid (and often package-free) bar that works to cleanse and nourish your hair.

Shampoo bars aren't necessarily better than your normal shampoo in terms of what it can do for your hair, however it is a great alternative for those that wish to do their bit for the environment as they tend to not contain plastic packaging. Just like traditional shampoos, you can also shop amongst a range of colours, scents and formulas to target your specific hair texture.

How do I use a shampoo bar?

Begin by wetting your hair as you would normally, before grabbing the shampoo bar and lathering up! Simply massage the bar into your scalp and hair, ensuring that all lengths are covered before thoroughly rinsing off. Follow up with your favourite conditioner and place the shampoo bar back in a soap dish tray to avoid mess or any slip ups (literally!).

Shampoo bars typically last anywhere between 50 to 90 washes, giving you some serious bang for your buck! Of course, this does depend on the size of the shampoo bar you invest in though.

How often should I shampoo my hair?

This completely depends on your hair type and if you've ever trained your hair to last long periods of time before getting greasy. Generally speaking, washing your hair once to twice a week is a good goal to work towards, although oiler hair types may suffer with going that long. For the days where hair does start to look a little too greasy, simply introduce a dry shampoo into the mix to tide you over until your next hair wash day.

By holding off on how frequently you wash your hair, you will be able to train it to go longer in between each session which will work favourably for both your wallet and the health of your scalp.
