About The Cornish Seaweed Bath Company

The Cornish Seaweed Bath Company: Cornish seaweed haircare and body care

The Cornish Seaweed Bath Company is a British family business founded in 2013 by Hannah and Richard, which handcrafts hair and skin care products in a small workshop in furthest West Cornwall. The company describes itself as a family business that has kept the same slow plant and seaweed extraction method since it began. Richard, co-founder, is a qualified herbalist with a degree in Natural Medicine; the first formulas were created in response to Hannah's hair changes from her forties onwards.

Hand-harvested seaweed as the base of the formulas

The core of the offering is seaweed, described by the company as rich in minerals, vitamins, amino acids and moisture-loving compounds. According to the brand, these help hydrate, soften and replenish skin from face to scalp, and nourish the scalp to encourage stronger, healthier-looking hair. The seaweed is hand-harvested from the Cornish coast and used in high quantities in the formulations.

Haircare range

The haircare range is built around the Super Nutrient line and includes shampoos and conditioners for normal, curly and blonde or purple-toned hair, as well as a detox shampoo, a deep conditioning hair mask, a Nutri-Therm hair serum, a light hold mousse and a specific line for eczema care. The company also sells oils and scalp treatments.

Facial, body and bath care

The skin and bath range includes seaweed soaps, facial care products, body lotions and oils, skin repair balms, body scrubs, organic lip balms and the Wild Seaweed Bath preparation. The company organises part of its range by skin concern — acne or scarring, eczema, psoriasis and rosacea — and by skin type — mature, dry, oily, combination, normal and sensitive. It also has a Fragrance Free line and products for dogs under the name Pups & Pooches, as well as bundles and gift sets.

Direct sales and try-at-home guarantee

Sales take place mainly through its online store, with free delivery from £45 and express delivery available. The company offers a 60-day guarantee for hassle-free exchanges or returns, designed so customers can try the products at home. The site shows a tiered gift system based on spend and a haircare guide aimed at understanding hair changes and building a calmer natural routine.
