“I am a woman of a certain age going through peri menopause and my hair was suffering badly. After every wash my hair was falling out in clumps. After just a couple of weeks my hair is now extremely healthy and shiny again.”

Description

Our Super Nutrient Purple Conditioner is gentle, caring, and naturally effective!

Specially formulated to complement our Super Nutrient Purple Shampoo, it helps neutralise brassy tones in blonde, silver, grey and lightened hair — while deeply conditioning and supporting overall scalp and hair health.

We make it using 100% natural ingredients, including a high volume of organic seaweed, herbs, and plant-based pigments from Blue Seaweed, Radish Extract, and Cape Jasmine Fruit. These natural colours deliver a vibrant purple tone without synthetic dyes, helping to brighten light hair gently and naturally.

It is suitable for all hair colours, types, and scalps — especially those looking to maintain blonde, silver or grey hair with a softer, more natural approach to purple toning.

This conditioner is free from silicones, SLS, parabens, artificial fragrances, colours, sulphates (including natural sulphates), is never tested on animals, and is vegan friendly.

We include our in-house extracts made from organic Seaweed, Tuber Fleeceflower Root, Angelica Sinensis Root, Frankincense and Mint Leaf — alongside rich plant oils, essential oils, and natural moisturisers, all carefully balanced to support hair softness and scalp comfort.

How to use: To neutralise yellow or brassy tones, use with every wash (along with our Super Nutrient Purple Shampoo) until your desired tone is reached. 

Then, use weekly or as needed to maintain brightness and balance, alternating with our regular Super Nutrient Shampoo & Conditioner.

We’re sure you will love it as much as we do!

Scent

We add Lavender, Blue Tansy, and Petitgrain essential oils to our Purple Haircare.

The combined aroma is soft, floral, and subtly citrusy — with calming notes of lavender, a gentle herbal sweetness from blue tansy, and a bright, green freshness from petitgrain.

These essential oils leave the hair and scalp feeling calm, balanced, and gently refreshed — evoking the scent of wild coastal meadows stirred by a soft ocean breeze.

How to use

Massage the Super Nutrient Purple Shampoo into wet hair, focusing on areas where brassiness is most noticeable. Leave on for 1–3 minutes depending on the desired level of toning, then rinse thoroughly.

Follow with Super Nutrient Purple Conditioner, applying to mid-lengths and ends. Leave on for 2–5 minutes before rinsing.

Toning results may vary based on hair type, porosity, and colour level. To neutralise yellow or brassy tones, use with every wash until your desired tone is reached.

Then, use weekly or as needed to maintain brightness and balance, alternating with our regular Super Nutrient Shampoo & Conditioner.

Recommended Regimen

• Step 01 (optional):. Apply Super Nutrient Hair & Scalp Oil as a pre-wash treatment. Leave on for 30 minutes or overnight for deep nourishment.

• Step 02. Cleanse with Super Nutrient Purple Shampoo to gently tone and refresh light hair.

• Step 03. Condition with Super Nutrient Purple Conditioner to restore softness, shine, and balance.

• Step 04. Alternate regularly with Super Nutrient Shampoo & Conditioner to maintain hydration, strength, and scalp balance between purple treatments.

• Step 05 (optional): Apply Nutri-Therm Hair Serum to smooth, hydrate, and protect from heat styling. Distribute 2–8 pumps through mid-lengths to ends before drying.

• Step 06 (optional): For extra volume, apply Hair Mousse to roots and mid-lengths before heat styling or blow-drying.

"The shampoo and conditioner are amazing - my hair dresser could not believe how soft, less frizzy and good condition my hair is from using them. The lip balm, facial oil and skin repair balm really do help to keep the skin soft and hydrated. Highly recommend!"

Introducing

Super Nutrient Purple Conditioner

After 2 years of development, our Super Nutrient Haircare was born — 100% natural, made with 60–80% organic seaweed and our herbal infusion.

It all began when Richard set out to create a shampoo and conditioner that truly worked for my hair — something natural, gentle, and effective. Those first prototypes, even before refinement, were better than anything I had tried before. As we developed them further, adding seaweed and refining the formula, I finally felt the difference: hair that wasn’t frizzy or flat, but balanced, healthy, and strong.

After sharing them with our amazing customers, the feedback has been incredible! We also had many requests for purple/blonde & light hair colour enhancer, so we set about seeing if we could create one that used completely natural ingredients - starting with a blue seaweed!

Two years later, we’re proud to introduce the next step in our haircare journey: Super Nutrient Purple Shampoo & Conditioner. With the same seaweed & botanical rich base, this range adds gentle, plant-based coloured ingredients (that also have wonderful hair and scalp benefits) to help tone and brighten blonde, silver, and grey hair — naturally.

We’re so excited to share them with you. We hope you love them as much as we do!

The Extraction Process

We create unique extractions using our organic Seaweed & other key herbs. We carefully prepare these over a number of days, & they form the base for each of our products.

Once this extraction is ready, we use this to make our unique products.

We make our Super Nutrient Conditioner with:

The key ingredients in our Super Nutrient Purple Haircare:

Organic Seaweed: Rich in minerals and amino acids that nourish the scalp, strengthen hair, and help maintain moisture balance.

Tuber Fleeceflower Root: Traditionally used to support healthy hair growth and strengthen roots.

Angelica Sinensis Root: Improves circulation to the scalp and helps promote fuller, healthier hair.

Frankincense: Extracted from whole resin, it helps soothe the scalp, adds shine, and supports a healthy hair environment.

Blue Spirulina: A nutrient-dense seaweed that helps condition and fortify hair. Its vibrant blue tone also contributes to the natural purple hue that neutralises yellow and brassy tones.

Cape Jasmine Fruit & Anthocyanins: Plant-based pigments that work with spirulina to gently tone blonde, grey, and silver hair — without synthetic dyes.

Kaolin Clay: Adds softness and volume while gently purifying the scalp.

Plant Oils: Argan and Oat Kernel Oils deeply moisturise, improve elasticity, and reduce breakage.

Essential Oils: Lavender, Blue Tansy, and Petitgrain offer a calming, coastal-inspired aroma and natural support for scalp balance.

Functions

Our Super Nutrient Conditioner is designed to provide healthy, strong, and nourished hair, as well as soothe and balance the scalp. Here are some of the key functions of the conditioner:

1. Provides nourishment: Our conditioner contains a high volume (80%) of carefully made Organic Seaweed and Herbs infusion, which helps to moisturise and balance the hair, providing it with the nourishment it needs to look and feel healthy.

2. Strengthens hair: The Organic Seaweed and other plant oils and extracts that we use, including Tuber Fleeceflower Root and Argan Oil, are known to improve hair strength and elasticity, reducing the risk of breakage and split ends.

3. Balances oils: Tuber Fleeceflower Root and Angelica Sinensis Root help to balance oils on the scalp and stimulate healthy hair growth, making the conditioner anti-aging for hair.

4. Soothes scalp: The Mint Leaf and essential oils of Clary Sage, Rosemary, and Peppermint provide a soothing and calming effect on the scalp, helping to relieve dryness, itching, and dandruff.

5. Suitable for all hair types: The conditioner is naturally gentle and balancing, making it suitable for all hair types, from fine to thick, and all hair colors, including grey, natural, and coloured hair.
