“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

The Complete Super Nutrient Purple Haircare Set

A ritual to tone, cleanse, condition, nourish & protect
Brightens blonde, silver & grey hair with seaweed & botanicals
Silicone‑free, sulphate‑free, powered by wild Cornish seaweed

Our complete Super Nutrient Purple Haircare Set — a naturally effective routine designed to brighten, hydrate, nourish, and protect light and colour‑treated hair using seaweed, herbs, and plant‑based pigments + tools (our shampoo brush and hair towel).

Purple Shampoo & Conditioner:
A gentle toning duo formulated with organic seaweed, blue spirulina, radish, and Cape jasmine fruit, along with other haircare botanicals. These plant‑based pigments help neutralise yellow and brassy tones while restoring softness, balance, and shine. Use 1–2 times per week, or every 3rd or 4th wash if you wash your hair less frequently.

Super Nutrient Shampoo & Conditioner:
Your everyday essentials — a balancing, sulphate‑free pair enriched with seaweed and botanicals. Together they hydrate, strengthen, and support scalp health while maintaining natural softness and vitality between purple treatments.

Nutri‑Therm Hair Serum:
Our award‑winning leave‑in treatment offers heat protection, hydration, and long‑lasting shine. With seaweed, bamboo, and eclipta, it smooths, strengthens, and seals moisture into each strand. Apply 2–8 pumps through mid‑lengths to ends after washing, before drying or styling.

Super Nutrient Hair & Scalp Oil:
A deeply nourishing pre-wash treatment designed to rebalance & soothe the scalp, and soften strands. Infused with seaweed, Broccoli Seed, Oat, and Jojoba oils, it supports moisture retention, strengthens hair, and encourages healthy growth. Use before shampooing — leave in for 20 minutes or overnight — or apply a small amount to dry hair to smooth and soften.

Shampoo Brush: Flexible and gentle for massaging the scalp and evenly distributing products. Ideal for pre-wash oil or shampoo.

Hair Towel: Quick-drying and lightweight, this soft towel reduces frizz and breakage with a secure button closure.

Ideal for:
Those looking to naturally maintain brightness and tone while deeply nourishing their hair and scalp — for soft, radiant hair that feels as healthy as it looks.

Set Contains:
1 x Super Nutrient Purple Shampoo
1 x Super Nutrient Purple Conditioner
1 x Super Nutrient Shampoo
1 x Super Nutrient Conditioner
1 x Nutri‑Therm Hair Serum (Marie Claire Award‑Winning!)
1 x Super Nutrient Hair & Scalp Oil

Scent

We blend Lavender, Blue Tansy, Petitgrain, Rosemary, Clary Sage, and Mint across our Super Nutrient Haircare range.

Together, these essential oils create a harmonious scent that is soft, herbaceous, and gently uplifting — with floral notes of lavender, a touch of sweet blue tansy, and crisp green freshness from petitgrain and mint. Earthier undertones of rosemary and clary sage add depth and calm.

This aromatic blend leaves the hair and scalp feeling refreshed, balanced, and quietly energised — like a breeze through sun-warmed coastal herbs and meadow flowers.

"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

The Complete 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!
