Best for people with dry, frizz-prone hair — including color-treated hair — who want an everyday moisturizing shampoo rather than a treatment shampoo. It's formulated for hair types dealing with dryness generally, but because it still uses sodium laureth/lauryl sulfate as its primary cleansers, it isn't the right pick for anyone specifically avoiding sulfates or with a very sensitive, easily irritated scalp; a sulfate-free line (such as Biolage's KeratinDose) would suit that need better. This is a mainstream retail shampoo, not a professional-only or clinical product.

HydraSource is worth choosing over a generic moisturizing shampoo specifically when dryness and frizz — not damage or color-fade — are the main issue, since its hyaluronic acid and aloe combination is built to add water-binding moisture rather than the protein- or oil-based repair that damaged-hair formulas focus on. It still uses standard sulfate cleansers, so it isn't the gentlest option on the shelf, but that also means it rinses cleanly without leaving hair feeling coated the way some ultra-rich moisture shampoos can.

Apply to wet hair and work into a lather with a massaging motion, then rinse thoroughly. Matrix recommends pairing it with HydraSource Conditioner or Detangling Solution as a complete routine, since the brand's strongest hydration claims are based on using the shampoo together with those products rather than on its own.

• Hyaluronic acid is a genuine humectant that holds water against the hair shaft, so the hydration this shampoo provides is less likely to evaporate quickly than one relying on oils alone.
• Safe for color-treated hair, and certified cruelty-free (Leaping Bunny) and vegan by the brand.
• Widely available across multiple bottle sizes.

• Contains sodium laureth and lauryl sulfate, so it can still feel drying to already-fragile or chemically-treated hair compared with sulfate-free alternatives.
• The brand's strongest hydration claim (up to 6x) is tied to using the full three-step system — shampoo, conditioner, leave-in tonic — not the shampoo alone.
• Fragrance-heavy formula, listing limonene, linalool, hexyl cinnamal, coumarin, and several other fragrance allergens.
