Following on from our recent post on Sulfate Free Shampoos, we thought it was time to look in detail at another controversial additive commonly found in shampoo – parabens.

There’s a growing movement from within the scientific community and among the public to ban the parabens found in cosmetics and shampoos. There is also a lot of misunderstanding and wild speculation as to what parabens actually are and what the risks are with using parabens.

Before we look at our favorite paraben-free shampoos, in true Dandruff Deconstructed style we’ll present the facts. Allowing you to make an informed decision on whether to continue to use parabens in your shampoos.

More specifically we’ll look at:

    1. What parabens are
    2. The risks of using parabens
    3. What the alternatives are

Then recommend the best paraben-free shampoos we’ve encountered on the market…

What are parabens?

Parabens, or parahydroxybenzoate esters, are a type of preservative used in shampoo to prevent the growth of microorganisms, such as bacteria, yeast, and mold. Not much is known about how parabens inhibit microorganism growth, but the mechanism is thought to be linked to the disruption of membrane proteins [1].

Are there different types of parabens?

If you look at the ingredient lists on popular shampoos, it’s not difficult to find parabens. The six you’re most likely to come across, on their own or in combination, are methylparaben; ethylparaben; n-propylparaben; isopropylparaben; n-butylparaben; and benzylparaben. These all have similar names because they are slightly different molecules based on the same structure of ‘p-hydroxybenzoic acid’.

While all parabens inhibit microorganism growth, they don’t all have the same action on human tissues. Methylparaben has been shown to strongly accumulate in breast tumors and urine, and n-propylparaben in urine [2]. This accumulation is in the nanogram level but combined with weak estrogen effects, forms the foundation for the public, scientific, and regulatory controversy surrounding parabens.

What are the risks of using parabens in my shampoo?

Parabens have been shown to cause irritant rashes in approximately 0.5 to 3.5% of people, and those with previous reactive allergies are most at risk (it should be noted that this figure is lower than other cosmetic preservatives) [3]. By far the most reported concern of paraben use is the ‘oestrogenic activity’. This means that parabens can mimic the hormone estrogen, which may lead to increased incidences of breast cancer.

The laboratory evidence for this isn’t overly convincing, as parabens have extremely weak oestrogenic effects – approximately 10,000 to 100,000 times weaker than natural estrogen [4, 5]. More concerning is the increased incidence of breast cancers located below the armpit since 1979 [6]. This fact is widely associated with paraben use because the preservative is also found in deodorants and creams which remain on the skin throughout the day – and so may be absorbed into the bloodstream.

The FDA has stated that the risk is unproven and that natural hormone fluctuations or diet have significantly stronger oestrogenic effects than parabens, which isn’t an unreasonable position [7]. The European Medicines Agency (EMA) takes the opposite view, and in the absence of convincing safety data, has reduced the maximum concentration of parabens permitted in cosmetics from 0.8% to 0.14% [8].

How can I tell if my shampoo is paraben free?

Many shampoos advertise themselves as paraben free these days (‘natural’ and ‘paraben-free’ are not the same thing). If you can’t see the full names, then look out for the corresponding E number, for example, methylparaben can be listed as E218. There are plenty of alternatives though.

What are alternatives to parabens?

Preservatives are used to give products longer shelf life. That said, the decaying process is natural and will eventually occur with or without preservatives of any kind. Skin care products do not, and should not, last forever. DHS Tar Shampoo, for example, doesn’t explicitly have any preservatives added at all. These shampoos tend to have a shorter shelf life, but personally, that’s something I’m prepared for if it means fewer harmful chemicals are added to my skin care products.

That said, there are plenty of alternatives to parabens that have caught our eyes over the years. Pharmaceutical Specialities Free & Clear Shampoo have added a preservative called Disodium EDTA, rated as a 1 hazard score (0 being the lowest) in the ewg skin deep database – and isn’t suspected of being an environmental hazard.

There’s also a number of natural preservatives you’ll see in shampoos these days. These include Tea Tree Essential Oil, Thyme Essential Oil, Grapefruit Seed Extract and Bitter Orange Extract.

Should I use parabens?

Parabens are used in shampoos as preservatives to prevent the growth of bacteria, yeast, and mold – an important quality given required shelf-lives. They can irritate skin in a small percentage of people, but not to a greater level than other cosmetic preservatives. If you suffer from a dry scalp or allergic conditions, then you may want to consider a ‘paraben-free’ certified alternative.

There isn’t any overwhelming evidence that they cause or contribute to the risk of getting breast cancer, although they are weakly estrogenic. The incidence of upper-quadrant breast cancer is increasing, although this correlation isn’t necessarily related to paraben use.

The EMA seems to have taken the most logical step in this instance to reduce risk in the absence of convincing evidence – parabens can still be added to cosmetics to prevent microbial growth, but at low enough concentrations to avoid accumulation.

The best paraben free shampoos

Over the years we’ve reviewed a number of paraben free shampoos.  Some good, some bad and some are frankly awful.  You can view them all by looking at our dandruff shampoo search.

Our favorites include:

Pharmaceutical Specialities Free & Clear Shampoo

Designed to treat Seborrheic Dermatitis, Dry Scalp and Psoriasis

Pharmaceutical Specialties formed in 1974 to “start a company to make better products than were commercially available for people with sensitive skin”. And boy, have they achieved it with this Free and Clear shampoo.

What is perhaps surprising on a website dedicated to dandruff treatments is that this isn’t a dandruff shampoo at all.

It’s rather a "a non-medicated, mild shampoo for sensitive skin and scalp.”

That said, we can’t use a medicated shampoo all the time, and this is my go to shampoo for those “between” washes.

BIOM8 Skin Conditioning Oil

Designed to treat Seborrheic Dermatitis, Dry Scalp

BIOM8 Skin Conditioning Oil is now part of my daily skin care routine. It’s as simple as that. I have lost count of the number of products I’ve reviewed over the years and I can count on one hand the number of products that have impacted me on this level.

If you suffer from dry skin, facial seb derm or rosacea I simply can’t recommend this product highly enough.

It even makes a good beard oil!

Maple Holistics Hydrate Shampoo

Designed to treat Dry Scalp

Maple Holistics Hydrate Shampoo has been superbly formulated to soothe and moisturize the scalp and hair. The ingredients have been carefully selected to decrease the chance that the product will irritate the skin. Using multiple low dose surfactants is a stroke of genius and only the fact the shampoo contains only one potential contact allergen says it all.

This is as close to perfection as you get in the commercial shampoo world.

I simply can't recommend this highly enough.

Nurture My Body Everyday Fragrance Free Shampoo

Designed to treat Dry Scalp

Nurture My Body Everyday Fragrance-Free Shampoo is an excellent gentle option for sufferers of a dry irritated scalp. The absence of any noteworthy irritants or allergens combined with the expert formulation of anti-inflammatory moisturizing ingredients makes an excellent change from the usual harsh surfactants and other toxins that lead to a vicious cycle of irritation and inflammation.

They've managed all of this in a shampoo that foams and washes well.

It's not particularly cheap, but this is simply one of the finest dry scalp shampoos out there.

Sebclair Shampoo

Designed to treat Seborrheic Dermatitis, Dry Scalp

Calling all sensitive scalp sufferers, if you haven’t yet found an anti-dandruff shampoo your scalp can tolerate, you haven’t yet found Sebclair shampoo. A piroctone olamine, Malassezia yeast quelling formula with extremely mild yet highly effective cleansers, accompanying scalp hydrators, flake fighters and natural anti-inflammatories. No fragrance, no essentials oils, no allergens. Sebclair shampoo really does stand out in our anti-dandruff crowd.

Bioderma ABCDerm Babysquam

Designed to treat Seborrheic Dermatitis and Cradle Cap

If your babe’s crusty cradle cap’s only getting worse, it’s time to try a leave on treatment – one which doesn’t leave your baby’s scalp looking like a grease ball. Enter Bioderma’s ABDderm Babysquam keratoregulating cream a 14 ingredient formula made from sensitive, hypoallergenic, moisturising, soothing and barrier building ingredients.

Useable 7 days a week with no fragrance or harsh preservatives Bioderma’s ABDderm Babysquam keratoregulating cream respects, repairs and conditions away crusty cradle cap.

Dead Sea Spa MAGIK Mineral Shampoo

Designed to treat Seborrheic Dermatitis, Dry Scalp and Psoriasis

Dead Sea Spa MAGIK Mineral Shampoo is a combination shampoo containing both salicylic acid and zinc pyrithione.  The thinking behind this shampoo is that the salicylic acid will soften and exfoliate existing build up and the zinc pyrithione will help prevent new build up from forming.

I’m generally a big fan of combination shampoos and this is no exception.  The shampoo feels great, has a nice light smell and leaves the hair feeling extremely soft.  It only contains one known contact allergen too - cocamidopropyl betaine.

If you suffer from mild seb derm I can’t recommend this highly enough.

Vichy Dercos Anti-Dandruff Sensitive Shampoo

Designed to treat Seborrheic Dermatitis

One of the best and mildest shampoos out there for seb derm sufferers with sensitive skin.

Containing both Piroctone Olamine and Salicylic Acid as well as being SLS free, paraben free, artificial color free this shampoo has an absolutely outstanding choice of active and inactive ingredients.

There are still two or three chemicals in there that some may find irritating. Otherwise this would have been a five out of five performer.

Sebamed Anti-Dandruff Shampoo

Designed to treat Seborrheic Dermatitis

Sebamed is one of the gentle yet most effective seb derm shampoos available.

The active ingredient is Piroctine Olamine - an excellent anti-fungal agent.

The rest of the shampoo has been formulated with panache.

DHS Fragrance Free Tar Shampoo

Designed to treat Seborrheic Dermatitis and Psoriasis

DHS Coal Tar Shampoo is an expertly formulated shampoo containing 0.5% coal tar and is the gentlest coal tar shampoo we’ve yet reviewed

We can't recommend this product or this company highly enough.
