“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.”

“I've been bothered about thinning hair that looked and felt lifeless. The shampoo and conditioner work together and after about a month's usage, the difference is amazing. I'm so glad I found you!”

“All the coated unwashed feeling has now totally gone, and my hair now feels soft and clean. It already felt so much thicker after a few months on your normal shampoo but now combined with the clean feeling after the detox shampoo, it is really uplifting and confidence building. The difference in the feel of my hair and the shine on it is amazing.” Tish

Description

The 4 Step Haircare Set + Detox

  • Pre-wash, Detox, Cleanse, Condition & Protect
  • Pre-wash oil + detoxifying shampoo + daily nourishment & protection
  • Silicone‑free, sulphate‑free, powered by wild Cornish seaweed

Discover our 4 Step Haircare + Detox Set — a complete ritual designed to rebalance the scalp, clarify product build-up, and nourish your hair from root to tip. This routine begins with a soothing pre-wash oil and detoxifying cleanse, followed by gentle regular care and lasting protection.

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.

Detox Shampoo: A deeply cleansing yet protective shampoo designed to lift build-up and impurities. Formulated with wild Cornish seaweed & botanicals, it gently resets the scalp without stripping moisture, while also softening and shielding strands. Ideal for starting your natural haircare journey, or as a reset if hair feels heavy or coated (e.g. post-salon or after heavy styling).

Super Nutrient Shampoo & Conditioner: The foundation of your routine. This sulphate-free duo is enriched with organic seaweed and botanicals including Tuber Fleeceflower, Angelica Root, Frankincense, and Mint. The Shampoo gently cleanses while maintaining balance, and the Conditioner restores softness, reduces breakage, and improves manageability without heaviness or residue , plus it re-seals hair cuticles. 

Nutri-Therm Hair Serum: Our unique, award winning, silicone-free serum offers 13 benefits, including heat protection, restructuring, and hydration. Infused with seaweed, bamboo, and eclipta, it smooths, shines, revitalises, and protects hair post-wash. To use: Apply 2–8 pumps to damp hair through mid-lengths to ends after washing and before drying. Less is more.

The 4 Step Haircare Set + Detox is ideal for: Anyone seeking a complete, natural haircare system that begins with scalp care and detox, and continues with gentle, daily support and protection — leaving hair soft, light, and naturally vibrant.

Set Contains:
1 x Super Nutrient Hair & Scalp Oil
1 x Detox Shampoo
1 x Super Nutrient Shampoo
1 x Super Nutrient Conditioner
1 x Nutri-Therm Hair Serum

Scent

"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!"
