Should you bin the bottle in favour of a shampoo bar?

Ecostore shampoo bars

I'm curious to know why you didn't test these with your 10. I absolutely love my Ecostore Volumising Shampoo bar. It lasts months and is gentle on my hair - my scalp is healthy. Easy to pack when traveling - and a subtle lovely perfume. Kaye

Rye flour

I have tried several shampoo bars, none worked for me. No matter how much I rinsed, I always seemed to have a lot of residue in my hair and it looked like I had not washed it for 2 weeks. What works great for me is rye flour. Make sure to get fine, not stone ground which will look like dandruff. I have shoulder long thick dry and frizzy hair. I take 2-3 tbsp in a little bowl into the shower and mix it is witch some water into a mash. Then use like shampoo. Rinse well and make sure to also clean your ears from the mix. Sometimes I use an apple cider vinegar rinse for conditioning (1 part acv, 2 parts water). The smell goes away quickly. I used to wash my hair twice per week with normal shampoo, now I only need I once. My hair is much softer and I have much less dandruff, which I used to have directly after washing my hair with shampoo.

Re: where to buy?

Hello Dawn,

You can buy the Lush shampoo bars from any Lush shop or online via their website. Head to: to see their full range.

Ethique products can be ordered via their website: or check out your nearest pharmacy or Farmers to see if they have them in store.

Kind regards,

Shampoo Bar

I was given a Shampoo Bar for Christmas and I was quite impressed with how it left my hair. Unfortunately, I was not impressed with the residue left on the shower walls, from the first wash. I towel dry the shower cubicle every night after use and the undesirable content was noticeable.

Lots of woo-woo, few active ingredients

One annoying thing about shampoo bars is that, being a boutique product, the current range is long on "natural" stuff that has no effect on hair apart from perhaps perfuming it a bit, and very few if any actual active ingredients that make shampoo shampoo. For example the Lush bar has one single active ingredient, the surfactant sodium lauryl sulfate, which is towards the harsher end of the scale of hair-care surfactants compared to things like the laureth sulfates. Others available in NZ have no identifiable active ingredients in them at all. The Ethique one at least has proven active ingredients, various surfactants, emulsifiers, lathering and chelating agents, and so on.
A disclaimer, I have nothing do with Ethique and had never even heard of them until I read the latest Consumer magazine, just surprised at some of the stuff that's being peddled under the label "shampoo" when it should be called "saponified fruit extract".

Great product

We (2 people household) have been using hair soap for some months now and we have only finished the first bar a couple of weeks back. It certainly is economical and I find it washes well and I don't need to wash my hair as often. Dirty Hippy also do a hair soap and we have just started on that and seems just as good. We did get a container when we got the first bar of Ethique and that keeps it dry as the base is a drainer with a cover over the top. I believe we have saved lots in changing and certainly will not be going back to liquid shampoo.

Global soap in Nelson

Been using them for 10 years or so, great product and lasts for ages. They featured Global soap on Country Calendar a year or two back.

Moisturising body bar

I have made a beeswax and shea butter moisturising body bar. The beeswax reduces dry skin on my hands associated with frequent hand washing/alcohol based hand gel at work. I melted 3 tablespoons beeswax, 3 tablespoons Shea butter, 3 teaspoons cornflour and 3 tablespoons baby oil in a clean tomato can sitting in a pot of hot water. I stirred the mixture with a disposable chopstick. Once combined and lump free, the mixture was poured into a silicone muffin tray. It is difficult to completely remove the waxy residue from the cooking utensils, hence the tin can and chopstick! Maura

Hair washing

I remember my grandmother and my Mum saying they used Pears soap to wash their hair when they were young. I use Health Basics Cream Body Wash and have done so for years - my hair is soft and smooth and I do not need a conditioner. It does come in a plastic container unfortunately. Can remember when I was a teenager (60 years ago) using beer as a styling liquid - great unless you got caught out in the rain when you smelled like a brewery.

Sodium Lauryl Sulphate

This chemical received a bad press in a UK tv medical programme a few months ago. Since then I've avoided any shampoo containing it. As I have fine hair I've resorted to baby shampoo. Check out:

Are any of these shampoo bars an anti-dandruff type. I'm currently using head & shoulders

Re: Anti-dandruff

Hi Cathy,

There are a few brands that make anti-dandruff shampoo bars. The best thing would be to do a web search.

Kind regards,

Soap/Shampoo container

To stop either soap or shampoo bars from becoming mushy put in a mesh draw string bag like supplied with gifts or soaps this allows it still to be used but doesn’t go mushy.

A shampoo bar to suit

Ethique now have a significant range of shampoo bars to choose from, so I am, over time, trying the ones that look right for my hair. So a bit of trial and error required, I reckon!

To stop bars becoming mushy

I think I've cracked it! I found a largish piece of oval shaped pumice on the beach and rasped down two sides to make flat surfaces for the bars, divided by the untouched pumice. This sits nicely in my shower tray. The bars don't seem to slip and slide overly on the pumice, which I rinse down before starting a new bar. And I can vouch for longevity. I wash my hair about every 3rd day and so far the bars have lasted a full year.

Try Frankie Apothecary for shampoo & conditioning bars

Can highly recommend Frankie Apothecary for the Kawakawa + Kūmarahou shampoo bar, and the vanilla and Kawakawa conditioning bars - all natural, no nasties, less commercial, local business, smells great and does what it says. Tried and tested by the whole family. 5 out of 5 from us.

Sodium laurel sulphate

Sensitivity or allergy to Sodium Laurel Sulphate is more common than people realise. It can produce symptoms from constant itchyness to flaking (no, not dandruff) to very sore lumps on your scalp that block the pores and cause painful build up in glands in the neck.
It’s a real shame that a shampoo bar would use this stuff when there are safe alternatives.

66 year old male with a reasonable amount of remaining fibres switched to bicarbonate of soda three years ago. Figure I could get a lifetime of clean and shiny hair for the cost of one of those bars.

Coconut in shampoos etc.

I have a sensitivity to coconut in products including shampoo, laundry detergent and dishwash liquid. I have been importing shampoo from Australia as I couldn't find one in New Zealand without coconut. Interesting to see that the Lush bar doesn't contain coconut but the Ethique one does. I must try the Lush bar.

Sunlight soap works too...

I have sensitive skin so years ago, before the mainstream switch to hypoallergenic products, I spent $$$ finding suitable shampoo. Someone told me "Sunlight" soap was quite gentle & effective on hair & skin, so tried it & haven't used shampoo for decades. My recollection is it took 2 or 3 weeks for my hair to 'adjust' to no chemicals, and even then no problems with being clean. Also great for hand washing clothes (different bar of soap for different purposes), plus cleans showers, sinks etc. I store in the open @ home to stop from going soft, & keep travel container open as much as possible when not on the move, plus cut into smaller blocks helps with drying out. I don't seem to have to wash hair as often, which is a bonus!

Get a sampler to find the best

Ethique does samplers so you can find the best type for your hair, it’s worthwhile to try a few, the first I tried I wasn’t happy with. Lush products are very highly fragranced and can be overpowering.

Keeping bars hard

For those concerned about keeping the bar hard, I usually keep my bars in the hot water cupboard. Let the moisture in the bar reduce and then the bar lasts longer. Also ensure that it does not sit in water after using it.

Are there any unperfumed ones? I was given a peony shampoo bar which has given me scalp eczema.
I love the idea of a shampoo bar but am loathe to pay a lot for one I will be too sensitive to.

try the Ethique sampler pack

Have a look at their website as there are different sampler combinations available - overall more cost effective than buying a whole bar of something that doesn't suit. Give what's left of the non-suitable samplers to family and friends to try.

Re: perfume

Hi Sue,

We had a look online and found a few unscented shampoo bars made with lye. Some manufacturers have trial sizes, but even if they don’t, there’s no harm in asking if they’ll send you a sample.

Kind regards,

Pure peony

Try pure peony shampoo bars, my partner has sensitive skin and he hasn't reacted to it.

Won't go back

Been using Ethique products for well over a year. I only have to shampoo twice a week. Get yourself some of their containers to keep bars dry, made from compost able material. Love this stuff and the company is helpful and dedicated to lowering the plastic on our planet.

Not convinced

I tried Dr. Bronner's shampoo bars, and while they seemed to work well enough they turned to goo in the plastic box I had to put them in. May work if you can keep them dry between uses.

Just try them

Been using ethique for a couple of years now. There's no going is softer and rarely needs conditioning ( and I usually use the conditioning bar) When you make the changeover it takes 2-3 washes to get the accumulated chemicals out of your hair.
