How to Apply

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.
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 to both

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

    I’ve noticed my greys are more smooth and easy to stay in place, instead of sticking out.

    Wash Shampoo
    Rated 5 out of 5 stars
    Best Shampoo ever!

    I’ve always used whatever shampoo is available. I’ve never been particularly picky or invested much in my choice of shampoo until now. However, I fell in love with Wash and can’t live without it anymore. My hair is thin, but this shampoo makes it feel healthy, shiny, and full!

FAQs

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 willl 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.

Arey Wash Shampoo contains our patent-pending Mela-9™ Complex which works to slow and repigment grey hair. It also delivers healthier, softer, glossier hair. Like all of our products, Wash Shampoo is made with clean ingredients and is vegan, cruelty-free and gluten-free.

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.

Wash and Smooth contain our signature 100% natural fragrance of cedar and sage.

Wash is a gentle shampoo, Smooth is a lightweight conditioner — and both are color-safe formulations.

Absolutely. Wash is a sulfate-free shampoo that's gentle enough to use on keratin-treated hair. Keratin treatments are designed to help manage texture. Using The System in tandem can help support healthy hair growth and manage texture for your future hair growth.
