The Ultimate Guide to Inis Hair Care: How to Bottle the Energy of the Sea

Inis hair care

Sulphate-free shampoo, conditioner and a clever hyaluronic sea salt spray, all powered by Atlantic seaweed. Here's everything you need to know about washing your hair with the Energy of the Sea.

If you've ever stood on the shore at Dog's Bay in Connemara, you know the feeling: cool wind, mineral-rich spray, and a sense of absolute clarity. For over 20 years, Inis the Energy of the Sea has captured that feeling in its signature cologne. Now it's bottled it for your shower.

Here at The Rowan Tree, we're proud to stock the full Inis hair care range. This isn't only about smelling good (though with notes of Sicilian lemon and sandalwood, you certainly will) - it's about bringing the restorative power of the ocean to your hair. Let's dive in.


Why "sea mineral" hair care? The science of the deep

The ocean is the ultimate source of life, and seaweed is its most potent plant. The Inis range doesn't just borrow a "marine scent" - it's formulated with a trio of nutrient-dense seaweeds harvested from the cold, pristine waters of the North Atlantic.

The algal trinity

Every bottle of Inis shampoo and conditioner is enriched with:

Seaweed What it does
Laminaria Digitata (Kelp) A moisture shield - rich in vitamins A, C and E, it helps lock in hydration and protect hair from environmental stress.
Fucus Vesiculosus (Bladderwrack) A mineral powerhouse of magnesium and zinc, for a healthy scalp and strong follicles.
Chondrus Crispus (Irish Moss) A natural softener that adds slip and smoothness, so detangling is a breeze - no heavy silicones needed.

Meet the range

1. Inis Sea Mineral Shampoo

Many shampoos use sulphates (SLS) to create foam. They work, but they also strip hair of its natural oils - leaving it dry and fading colour. The Inis Sea Mineral Shampoo is sulphate-free and paraben-free, using gentle plant-based cleansers that lift dirt while respecting your hair's moisture barrier. As you massage it in, the shower steam lifts those sparkling top notes of lemon and neroli - an instant mood booster. Gentle enough for daily use, safe for coloured hair, and perfect for anyone who wants lightweight, bouncy hair.

2. Inis Sea Mineral Conditioner

The perfect partner to the shampoo - it doesn't just coat hair, it nourishes it. Alongside the seaweed trio, the Inis Sea Mineral Conditioner features shea butter (deep lipid replenishment that tackles frizz and dryness) and argan oil (glossy shine that smooths the cuticle). The result: hair that feels silky, detangled, and smells incredible for hours.


Bundle up and save. If you're buying both anyway, it's a no-brainer - our Shampoo & Conditioner Bundle costs less than buying them separately. Only at The Rowan Tree.

3. Inis Sea Salt Spray

This is the one that changes the game. We all love the look of beach waves - that textured, voluminous, effortless style you get after a swim. What we don't love is the dry, crunchy, straw-like feeling salt sprays usually leave behind. Inis solved it by adding hyaluronic acid to the Inis Sea Salt Spray:

  • Sea salt gives you the grip, volume and texture.
  • Hyaluronic acid is a moisture magnet, drawing hydration into the hair shaft to counteract the drying effect of the salt.

How to use it:

  • For waves: spray generously onto damp hair, scrunch sections upwards with your hands to encourage curl, and let it air dry.
  • For volume: flip your head upside down, spray into the roots of dry hair, and blast with a hairdryer for instant, fresh-smelling lift.

The scent: a perfume for your hair

Hair is porous, so it holds onto scent beautifully. Layer the shampoo, conditioner and salt spray and you create a subtle "scent cloud" that moves with you all day:

Layer Notes
Top Sicilian lemon, bergamot, marine notes - the sparkle
Heart Geranium, lily of the valley - the clean floral
Base Sandalwood, clove, musk, oakmoss - the lingering warmth

Because Inis is an aromatic aquatic fragrance, it's universally appealing — fresh, clean and unisex. The scent of a happy, sunny day, bottled.


Clean, ethical and Irish

When you choose Inis, you're choosing a brand with a conscience:

  • Cruelty-free - never tested on animals.
  • Plastic neutral - for every piece of plastic used, Inis funds the removal of plastic from the environment.
  • Ocean protectors - Inis is the core funder of the Irish Whale and Dolphin Group, helping conserve the creatures that call the Atlantic home.
