How to Apply

How to apply Arey Wash shampoo
Wash is a gentle shampoo with proactive ingredients that stimulate pigment production and support hair health.

HOW TO USE:
  • Dispense a silver dollar-size amount into your hand and work the product into a lather.
  • Wet hair and apply to scalp and roots.
  • If more lather is needed, add more water and continue to massage into the scalp.
  • Remember to focus on the back of your head as well.
  • Allow the product to sit on the scalp for several minutes.
  • This allows the active ingredients to fully absorb into the scalp.
  • Rinse thoroughly, and follow with Smooth conditioner.
How to apply Arey Smooth conditioner
Smooth is a nourishing and clean conditioner that helps retain moisture inside the hair strand.

HOW TO USE:
  • It leaves a conditioning barrier to help hair to look healthier without feeling weighed down.
  • Depending on your conditioning needs, apply a quarter to silver dollar size amount to mid shaft and ends.
  • Tip: Conditioners should not be applied on or near the scalp.
  • Smooth can be left on the hair for several minutes for deeper conditioning.
  • Use a wide tooth comb to evenly distribute before rinsing.
  • Best when used with Wash shampoo.

How it Works

Wash Shampoo

  • Stimulate

    A clinically efficacious peptide helps with repigmentation by stimulating the MC1-R (melanocortin 1 receptor).
  • Prepare

    Wasabi extract, sesame seed extract and zanthoxylum bungeanum fruit extract work to help the active ingredients penetrate the scalp and access the follicle
  • Nourish

    Ginseng, fo-ti and caffeine provide nourishment to the root to promote cell turnover and promote healthier hair growth
  • Volumize

    Panthenol plays a role in activating the proliferation of cells in the skin barrier, and also helps bind water to the skin and hair, balancing and adding volume
Wash Shampoo

Smooth Conditioner

  • Nourish

    Hydrolyzed barley protein and coffee extract work together to build internal strength in the hair strand
  • Protect

    Jojoba and shea butter work to seal the cuticle and protect the hair from heat and environmental stress
  • Volumize

    Panthenol actively attracts and retains moisture in the hair strand, helping it look and feel more volumized
Smooth Conditioner

    unexpected cure!

    I ordered Arey shower duo when I noticed a gray hair growth. This has helped soften the wirey texture of my new grays. I had been scared to try it because I believed I depended on medicated dandruff shampoo. What I didn't expect was for my dandruff to GO AWAY with the duo!!! no more harsh shampoos for me. my hair is so soft and shiny now. what an awesome surprise!!!

    Love using the shower duo

    The shampoo and conditioner work really well. I’ve been using the duo, along with the capsules, daily for almost a year now, and I noticed my hair was visibly shinier, manageable, and more healthy looking almost immediately. I notice a difference when I have to use a different shampoo/conditioner, and it bounces back as soon as I go back to the duo. My grays are more blended and much less noticeable now.

FAQs

The Shower Duo pairs Wash Shampoo and Smooth Conditioner to gently cleanse, hydrate, and strengthen hair while addressing early signs of aging hair, including slowing the appearance of greys and preserving your natural pigment over time. Wash helps support a balanced, healthy scalp. Smooth locks in moisture, reduces breakage, and leaves hair softer and more manageable.

Most customers see softer, stronger, more hydrated hair within the first few washes and improvements in the appearance of new greys with regular use over 3–6 months. Consistency matters. Aim to use the duo 3–5 times per week for maximum benefit.

Unlike standard cleansers and conditioners, the Wash Shampoo is formulated with the patented Mela-9® Complex, a blend of botanicals, antioxidants, and peptides shown to help slow early grey appearance and preserve existing pigment. While Smooth Conditioner delivers hydration and strengthens strands for healthier-looking hair.

Yes. The formulas are gentle and color-safe, free of harsh sulfates, parabens, phthalates, synthetic fragrances, PEGs, formaldehyde, and dyes. They clean and condition without stripping color or compromising keratin or other salon treatments.

Absolutely. The Shower Duo works beautifully as part of your overall Arey routine. For broader support in slowing grey growth and improving hair health, we recommend pairing Wash & Smooth with Not Today, Grey™ and To The Root® Scalp Serum.

For best results, use the Shower Duo 3–5 times per week. Focus Wash on the scalp and roots, then apply Smooth from mid-lengths to ends. Leave each on for a few minutes when possible to let the formulas work, then rinse thoroughly.

Yes. The Shower Duo is formulated without animal-derived ingredients and is vegan, cruelty-free, and gluten-free. It’s also made without many common harsh additives.

Yes. Wash Shampoo supports a healthy scalp and stronger hair at the root, while Smooth Conditioner delivers lightweight hydration that helps reduce breakage, soften strands, and improve manageability.

Smooth Conditioner is ideal for fine to medium hair. If your hair is medium to coarse or experiencing significant dryness or damage, we recommend layering in Masque Deep Conditioner for deeper hydration and repair.

No — the formulas are designed to hydrate without weighing hair down. While they deliver moisture and softness, they rinse cleanly and leave hair feeling balanced, not greasy or heavy.

Yes. The Shower Duo can be used on all hair types and is especially well suited for fine to medium hair.

For medium to coarse hair, we recommend layering in Masque Deep Conditioner for added moisture, nourishment, and manageability.

The Shower Duo is formulated to support a healthy scalp environment, which is essential for maintaining natural hair pigment. Wash Shampoo and Smooth Conditioner use a blend of antioxidants, peptides, and plant extracts, including our patented Mela-9® Complex, to help reduce oxidative stress at the scalp, a key driver of melanocyte dysfunction and premature greying.

By cleansing gently without stripping and nourishing the scalp and hair, the Shower Duo helps support melanocyte function, preserve existing pigment, and create optimal conditions for healthier, more resilient hair growth over time.

Yes, all of our products are sulfate-free. Our Wash Shampoo creates a luxurious lather and leaves hair perfectly clean, soft, smooth and balanced. Bubbles will also be smaller in nature than those shampoos made with sulfates. Just add a bit of water and you'll be able to create a lather.

Many conditioners contain silicones that are too heavy – especially for fine hair. They build up on your strands leaving your hair limp and lifeless. That’s why we use Amodimethicone, a silicone derivative, in our Smooth Conditioner. The light, protective coating that amodimethicone provides helps to improve the visible softness and shininess of the hair by smoothing the hair shaft and locking in moisture. Unlike other silicones, Amodimethicone won’t cause pore-clogging buildup on your hair and scalp.

Amodimethicone responds to the needs of each strand by locking in moisture, smoothing your hair, and controlling frizz. Amodimethicone not only smoothes your hair, but it also improves the texture of fine or wavy hair, controls frizz, repairs the hair shaft on damaged hair, reduces hair damage by preventing tangling, softens, and smoothes your hair and increases shine.
