3 Important Buying Tips

1 Make sure oat is an important ingredient

Many hair products boast of containing natural ingredients. You should, however, always look at the ingredients list to see exactly how natural the product is.

The ingredients list will always start with the most prominent ingredient. Often this is water or oil.

When looking for oat hair soaps, find one with a fairly high oat content. You don’t want oat to be the last ingredient of the product.

For example, the Bare Oat & Plantain Natural Solid Shampoo Bar has oat listed as is the 8th ingredient on the list out of 18 which is very good.

2 Other moisturising ingredients

For a truly moisturising oat hair soap, you need other ingredients high on the list which offer hydration.

Oils tend to be high on the list as all soap is made from sodium hydroxide (lye) and a fat such as oil or butter.

Look for ingredients such as Shea butter, olive oil, coconut oil, castor oil etc.

3 Check for harmful ingredients

Luckily, many shampoo bars are made from mostly natural ingredients however some do contain harmful chemicals or have a high pH.

As much as we think they may be the better choice as they are plastic free, some aren’t always the better alternative.

When looking for soothing oat hair soaps, check for ingredients such as palm oil or SLS’s which stands for sodium Lauryl Sulfate.

You’ll probably have heard of sulphate-free shampoos as sulphate is actually a pretty dangerous ingredient.

It’s what causes shampoo to lather and it strips your hair of its essential oils.

You definitely want to avoid sulphates in both your shampoos and your shampoo bars.

Also ensure that your oat hair soap is free from artificial fragrances and other harsh preservatives.
