7 Shampoo Bar Myths & Facts You May Not Know

You probably haven’t used one yet due to misinformation. Here are some shampoo bar myths and facts to clear things up

By Diane Small

We all want clean, sweet smelling, shiny, lustrous hair. The quest for the perfect shampoo is, therefore, never ending for some of us.

But few people consider shampoo bars, and that’s a shame. These are an effective, cost-efficient and eco-friendly alternative to regular shampoos. But there are a lot of shampoo bar myths out there that may deter you from buying one. Let us clear those myths up, and share the facts!

What Is A Shampoo Bar?

A shampoo bar is basically just a solid version of your standard liquid shampoo. But since they’re not in a water base, they don’t need many of the nasty ingredients that regular shampoos need.

For example, you’ll find that shampoo bars are usually free of preservatives like parabens, liquifiers like phthalates, smoothers like silicones, and foamers like SLS/SLEs. As a result, they’re gentler on your hair, scalp, and overall health.

Usually, coconut and/or aloe are used for their cleansing and hydrating properties. But you’ll find lots of other all natural ingredients, such as essential oils, shea butter and keratin.

Why These Bars Are Eco Friendly

There are loads of reasons why shampoo bars could be considered to be a far more eco friendly option than regular shampoos.

Mainly, they don’t use plastic packaging. But that’s not all!

Shampoo bars also contain fewer, if any, harmful ingredients (depending on the brand). And since they don’t contain water, they’re lighter. That means they take up less energy when they’re transported.

How To Use Shampoo Bars

There are lots of shampoo bar myths on how to use these products. But it’s simple! You should use a shampoo bar the same way you’d use a bar of soap. The only difference? You’ll lather this onto your scalp instead of your body.

If you have long, thick or curly hair, rub the bar between your hands. Work up a lather. Once you feel there’s enough product between your palms, massage it directly onto your scalp. Work the lather down to your strands if you feel the need to.

Got short, fine or straight hair? Just apply the product directly onto your scalp and work it down. Rinse thoroughly. Got dyed hair? Don’t worry, these won’t strip your colour!

7 Shampoo Bar Myths, Busted

Still concerned a shampoo bar isn’t for you? Not surprising, since there are quite a few shampoo bar myths out there! Let’s clear those up.

Shampoo Bar Myths

Shampoo Bar Myth #1

Shampoo bars and soap are pretty much the same thing.

TRUTH

No! They’re completely different, with a different pH level and formulation in each. A good shampoo bar should have a pH-balance of around 6- 6.5%. Soap, on the other hand, is far more acidic, with a pH of around 10. 

Shampoo Bar Myth #2

Dry shampoo is really expensive.

TRUTH

The average bar works out to cost less than 10 cents per wash. Whilst the initial purchase of a dry shampoo might be more expensive than say, your typical bar of soap, in general, shampoo bars last on average 2-3 times more than bottled shampoo. That’s due to their more highly concentrated formulas, making them a more cost-effective choice. Oh, and just so you know, bottled shampoo is around 80% water!

Shampoo Bar Myth #3

Dry shampoos don’t work on all hair types.

TRUTH

Dry shampoos come in formulations for all types of hair. Even Afro/curly hair!

Shampoo Bar Myth #4

Like many of the worst commercial shampoos, dry shampoos also contain harmful ingredients like SLS.

TRUTH

You can find dry shampoos that are free from sulfates (SLS/SLES), silicones, parabens, phthalates – all nasties, in fact!

Shampoo Bar Myth #5

Dry shampoos don’t work as well as ‘regular’ shampoos.

TRUTH

Not at all. Some people think this because they don’t foam as much as regular shampoos. But that foam comes from SLS, which is a harsh detergent whose main function is simply to bubble. It’s not formulated to help clean. Despite being the more eco-friendly option, there is no compromise on quality and how great they are for your hair.

Shampoo Bar Myth #6

They won’t lather like regular shampoo.

TRUTH

Well, that’s true. See above. But that being said, despite being free of SLS, some bars still create a super creamy lather. That’s thanks to gentle, natural ingredients like aloe vera and others.

Shampoo Bar Myth #7

There’s no big difference between wet and dry shampoos, so why bother?

TRUTH

There are loads of benefits for dry shampoo bars! Here are but a few:

  • they last approximately 2-3 times longer than bottled shampoo.
  • most bottled shampoos contain predominantly water, whereas dry bars are undiluted. 
  • dry shampoos are not usually packaged in plastic
  • they’re great for travelling, as they’re light, and you don’t have to separate them as ‘liquids’
