“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 Bio-Active, Natural, Seaweed & Herbal Super Nutrient Purple Haircare is gentle, caring and naturally effective. It’s specially formulated to help tone and brighten blonde, silver, grey, and lightened hair, while nourishing your hair and scalp so they can look and feel their best.

We make it using 100% natural ingredients, including a high volume of organic seaweed, herbs, and naturally derived plant pigments that support both tone and hair health.

It is suitable for all hair colours, types, and scalps — particularly beneficial for lighter tones — making it ideal for anyone looking to gently maintain brightness while improving overall hair and scalp vitality.

We recommend using this set 1–2 times a week, alternating with our regular Super Nutrient Shampoo and Conditioner to maintain tone while supporting long-term hair strength, hydration, and shine.

It’s 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 & Mint Leaf. Alongside these, we use hair-loving plant oils, gentle plant-based cleansers, and essential oils — all carefully adjusted to a scalp- and hair-friendly pH level.

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

Contains:
1 x Super Nutrient Purple Shampoo
1 x Super Nutrient Purple Conditioner

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.

"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 Haircare Set

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.

Haircare herbs

The key ingredients in our Super Nutrient Purple Haircare Set:

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

With 60- 80% organic seaweed & herbs, our Super Nutrient Haircare is designed to improve hair strength, elasticity & shine. It helps balance hair oils, stimulate healthy hair growth, prevent hair loss & soothe the scalp.

The natural, plant-based formula cleanses gently, while the essential oils of Clary Sage, Rosemary & Peppermint add fragrance & further improve the health of your hair & scalp.

Our Haircare is pH-balanced to ensure it is suitable for all hair/scalp types & is free from harsh chemicals, making it a gentle & effective choice for your hair care routine.

About Us

We are Hannah and Richard. We met down here in furthest west Cornwall.

We combine Richard’s knowledge of traditional oriental medicine (he has a degree in Traditional Chinese Medicine and is a practicing Acupuncturist), with our love of the wild Cornish Sea and its’ amazing seaweeds! From this we create unique skin and body care for everyone to enjoy!
