Dry hair doesn't just need a conditioner that works harder — it needs a shampoo that stops undoing the work conditioning does. Sheer Hydration Shampoo reframes the cleanse step: instead of stripping the hair shaft and leaving moisture replenishment entirely to what follows, it delivers hydration and shine-boosting actives during the wash itself. The result is hair that arrives at the conditioning step in better condition than it started.

Sheer Hydration Shampoo is built around two marine botanical actives that bring genuine hydration function — not just marketing — to a cleansing formula.

Chondrus Crispus Extract (Irish Sea Moss) is a seaweed-derived humectant that forms a lightweight moisture-binding film on the hair shaft. Rich in polysaccharides, minerals, and amino acids, Irish Sea Moss draws water into the hair shaft and holds it there through the wash — preventing the net moisture loss that most shampoos cause. It also contributes to the smooth, silky feel at rinse-out that distinguishes this formula from a standard clarifying wash.

Spirulina Platensis Extract (blue-green algae) is dense in proteins, vitamins, and antioxidants including Vitamin B12, iron, and beta-carotene. In hair care, Spirulina's amino acid profile helps reinforce the cuticle surface and adds shine-amplifying properties — the reason the formula delivers a visible shine boost even at the wash step. Its antioxidant content also protects the hair shaft from environmental oxidative stress accumulated through the day.

Panthenol (provitamin B5) penetrates the cortex and binds moisture at a structural level, improving elasticity and contributing to the softness and manageability that accumulates with repeated use. Lactobacillus Ferment — a probiotic-derived ingredient — supports the scalp's natural microbiome balance and acts as a gentle antimicrobial, contributing to scalp health without disrupting its protective barrier.

Polyquaternium-44 and Cinnamidopropyltrimonium Chloride provide conditioning film, anti-static properties, and improved manageability — reducing mechanical breakage during detangling post-wash. Hydroxypropyl Guar Hydroxypropyltrimonium Chloride (conditioning guar) adds slip and surface smoothness. Dimethicone provides cuticle-smoothing and shine at rinse-out.

The surfactant system — Sodium C14-16 Olefin Sulfonate and Cocamidopropyl Hydroxysultaine — is a milder, sulfate-free alternative to SLS/SLES that produces a rich lather without aggressive stripping, making it well-suited for dry or colour-treated hair that needs daily washing without cumulative desiccation.

When used with Sheer Hydration Conditioner, consumer studies showed 93% said hair looked softer and 91% said hair looked healthier after use.*

Colour-safe, vegan, paraben-free, made without gluten, cruelty-free.

Metro Vancouver note: Hard water mineral deposits create a barrier on the hair shaft that blocks moisture uptake, meaning hydrating shampoos underperform on hair with active buildup. If results are less than expected, a chelation step before your regular routine may be the missing variable. See our Hard Water Hair Damage Page for the protocol.

Who It's For Dry, dehydrated, or dull hair of any texture. Colour-safe for everyday use on coloured or chemically treated hair. The sulfate-free formula is gentle enough for daily washing without stripping. Works across fine, medium, and thick hair. Particularly effective for hair that looks dull, feels rough after washing, or is recovering from chemical services or heat damage.

Also available in 300ml
