The Collection
Hydrating Shampoo
The Hair Gain Hydrating Shampoo (250ml, £23) is a nourishing, peptide-enriched formula designed to intensely cleanse, hydrate, and strengthen both hair and scalp. Expertly blended with Pea Peptides, Marshmallow Root Extract, Phytantriol and Panthenol, it works from the very first wash to reduce breakage. Marshmallow Root Extract soothes the scalp and seals in essential moisture for lasting hydration, while Pea Peptides fortify the hair’s structure, making strands stronger and more resilient to damage.
Hydrating Conditioner
This hydrating conditioner (250ml, £23) is infused with a powerful blend of Pea Peptides, Marshmallow Root Extract, Phytantriol, and a B Vitamin Complex that includes Panthenol and Niacinamide, strengthening each strand while boosting volume, shine and manageability. Pea Peptides reinforce the hair’s structure to prevent breakage and add instant body, while Marshmallow Root Extract locks in moisture and soothes the scalp for ultimate hydration. Phytantriol supports colour protection, and Niacinamide improves elasticity for long-term hair health.
The Shampoo & Conditioner Starter Kit is available as a duo (£42), and the Shampoo & Conditioner refills are also available as a duo (£35) and individually (£17.50 each). Crafted from 100% recycled materials, these sleek, reusable bottles are designed to hold the shampoo and conditioner refills, offering a stylish, sustainable alternative to single-use plastic.
