How much product should I use?

Our products are all very concentrated so you don't need to use a lot. Depending on the length of your hair, you should only need a small palm-full amount to cover your whole head.

Are your products cruelty free?

Martinsson King is proudly vegan. We are committed to the protection and preservation of nature and wildlife and are vehemently opposed to animal cruelty. We do not use any animal ingredients and will never consent to animal testing within international markets in order to facilitate distribution within those markets.

Do your products contain sulphates or parabens?

No. We believe in transparency. All our ingredients can be viewed directly on each product page in the webshop.

Are your products suitable for coloured hair?

Yes, all our shampoo/conditioning products contain colour protection.

Are the products natural and organic?

Our formulas can be stripped down to entirely pure ingredients, free from anything toxic. We select naturally derived over man-made components where possible, and use the minimal number of ingredients for an impeccable, trustworthy result. We are part of the Green Salon initiative who work tirelessly to ensure no harmful chemicals are used in the development of hair products.

Why isn't my shampoo foaming much when I wash my hair?

Sulphate-free shampoos generally do not foam as much as traditional formulations. If the first shampoo does not foam a lot then we recommend a second shampoo to complete the cleansing process.

Is MK suitable for daily use?

Yes. Our shampoos are deep cleansing, colour protecting and gentle enough to use everyday.

Do your products contain heat protection?

Our new 'Style Memory ' is a heat/UV protecting spray that will shield your hair from heated styling tools up to 200°C/420°F.

What are serum infusions?

Apply them into your freshly washed hair for easy styling or add them to your shampoo and conditioners to boost their performance. They’re so lightweight that your hair will feel like there is no product in it at all.

Which serum is best for me?

We currently have a Volume, Hydrating and Smoothing infusion. Choose one or more serum that is suitable for your hair type and the results you want to achieve.

Can l use more than one serum?

Yes. Pick and choose how you blend your products and combine them until you get your own customised hair care system.

When should l use a dry shampoo?

What does 'No Green Washing' mean?

We work directly with our chemists so we can personally verify every ingredient for safety and sustainability. With a focus on performance and outstanding results we reject any excessive or potentially toxic elements. We reject the use of any unnecessary ingredients purely for their marketing value and meticulously list all the contents of our formulas for clarity and transparency on our website.

What does 'Climate Compensated' mean?

Carbon Footprint is an independently run, non-profit organisation that audits carbon emissions for companies who want to be sustainable in their business practices. Using a vigorous 40 point plan, they assess the emissions created during the production and distribution process of our products to calculate an amount that neutralises the environmental impact. Martinsson King pays five times that amount to fund sustainability programs around the world through initiatives that range from green energy/reforestation programs to the distribution of filters to ensure drinkable water in impoverished communities.
We want you to use our products with confidence and are extremely proud of our association with Carbon Footprint LTD.
