Rated 4.4 out of 5 stars
181 Reviews

Preserves Pigment | Hydrates Deeply | Medium+ to Coarse Hair

Deeply cleanse, hydrate, and restore with The Deep Treatment Duo. This set pairs Wash Shampoo to proactively delay greys with Masque Deep Conditioner to nourish, soften, and strengthen. Ideal for medium, coarse, or damaged hair.

WHAT IS IT?

 

The Deep Treatment Duo pairs Wash Shampoo — powered by our patented Mela-9® Complex to preserve pigment while cleansing and balancing the scalp — with Masque Deep Conditioner, which restores softness, shine, and strength without the heaviness or buildup of traditional deep conditioners. This clean, silicone-free formula reduces visible breakage, tames frizz, and supports elasticity for healthier hair over time. Color-safe, dermatologist-tested and hypoallergenic.

100% natural cedar + sage scent; made without silicones, sulfates, parabens, phthalates, synthetic fragrance, PEG, formaldehyde, or dyes.

WHAT'S INCLUDED?

 

Full-Size Wash Shampoo (8.45 fl. oz. / 250mL)
Full Size Masque Deep Conditioner (6.76 fl. oz / 200mL)

Please note: This set does not come pre-kitted in a box. All items are packaged separately.

HOW TO USE

 

1. Cleanse with Wash Shampoo. Massage into scalp; rinse thoroughly. Use 3–5× per week.
2. Apply Masque Deep Conditioner generously from mid-lengths to ends. Rinse.

Wash is sulfate-free and concentrated, so the suds are naturally smaller. For a richer, creamier lather, mix with a little water in your hands before applying. 

Pro Tip: To prioritize slowing greys and support repigmentation, pair with Not Today, Grey and use both consistently for 3–6 months.

    Masque Deep Conditioner
    Rated 5 out of 5 stars
    Not too heavy, but hydrating!

    I have really thick, wavy hair and use this in place of my regular conditioner about once a week. My hair has looked a lot shinier and healthier, but what I really like is that it doesn't feel too heavy! Other hair products have made my hair look nice superficially, but it was being weighed down with extra ingredients that were ultimately damaging my hair. Love that Arey makes my hair look nice and actually be healthy!

FAQs

The Duo combines two powerful steps: Wash Shampoo, which features the Mela-9™ Complex — a blend of a clinically-efficacious peptide, antioxidants, and botanical extracts designed to slow grey growth, preserve natural pigment, and repigment greys over time, while gently cleansing the scalp without over-stripping. The Masque complements Wash by delivering deeply nourishing hydration, smoothing, strengthening, and improving hair texture—especially helpful for greys, chemically processed, heat-styled, or coarse/dry strands. When used together, you get both scalp/pigment benefits and restorative moisture/texture benefits.

With consistent use of the Duo, many users see improvements in softness, shine, manageability, and hair strength within the first few washes. Texture of grey hairs will often feel softer more quickly. Slowing of greys is more gradual — it depends on things like percentage of grey, genetics, stress, overall health, and how consistently you use the regimen (including supplement support if used).

That depends on your hair's condition. For normal or mildly dry hair, using Wash every time you shampoo (which may be a few times per week) and following with Masque once a week (or when hair feels especially dry/damaged) provides a great maintenance/regeneration schedule. If you have medium+, coarse, dry, or very damaged hair, Masque can replace your regular conditioner and be used after every wash for full benefit. Adjust based on how soft, hydrated, and manageable your hair feels.

Yes. Wash Shampoo is formulated without sulfates, parabens, phthalates, synthetic dyes, and harsh chemicals; it’s color-safe and gentle even on keratin-treated hair. Masque similarly avoids heavy buildup and is silicone-free, so it complements Wash’s gentler cleansing. For sensitive scalps, both should be tolerable, though as with any new product, doing a patch test is recommended.

Yes. Using Wash alone will target scalp health, gentle but thorough cleansing, and the pigment-preserving effects of the Mela-9 Complex. Using Masque alone will deeply hydrate, improve softness and texture. The real benefit of the Duo is synergy: Wash cleanses and primes hair + scalp, helping active ingredients reach where they can work best; Masque seals in hydration, smooths, and improves resilience. Together you get both pigment support + strong, healthy, touchable hair.

It can. Wash Shampoo, via its Mela-9 Complex, is designed to slow grey growth and preserve or repigment existing greys over time. Masque won’t repigment greys itself, but it helps greatly with how grey hair feels and looks (texture, brittleness, dryness). If your goal is to more proactively address greying, the Duo works best when paired with the Not Today, Grey daily supplement.

For Wash Shampoo: wet hair thoroughly, massage into scalp, let the lather sit on your scalp for a minute or two before rinsing — this gives the Mela-9® Complex time to interact. For Masque: after washing, apply from mid-length to ends, leave on for 3-5 minutes for regular conditioning; longer (up to 10 min) when hair is especially dry or damaged.
