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.

    The Shower Duo

    I don't want to wash my hair with anything else. I have thin hair, and the volume, texture, and shine of my hair has been maximized in the 1.5 years I have been using this shampoo and conditioner. I'm in my late 30s too, and have seen a noticeable difference in the pigment change and texture of my greys and whites. Compliments about my hair happen often!

    Positively Impacting My Hair

    I have been battling grays in my mid twenties. By my early thirties I stopped dying my hair because it would grow back within a week. Recently for my birthday I decided to dye it with a demi-permanent dye one more time and purchase Arey products to use. I have seen a notable difference after a month of use. I have less grey appearing than I have before. I'm not the biggest fan of the scent for the wash but I am also generally fragrance free. The wash and conditioner pairs well together and leaves my hair feeling soft. I have a mix of wavy/curly hair. I didn't think something would positively impact my graying hair but I do see a difference in the amount of grays growing. I will continue to use this product.

    Slowed graying gradually

    I have some wiry grays mostly around the temples and have been using this shampoo and conditioner for a year now. The gray hair’s texture is quickly smoothed but also I’ve noticed the graying has slowed over time too and am finding way less new grays.

    Hi Taylor, thank you so much for taking the time to share your experience with The Shower Duo after a full year of consistent use. We're really pleased to hear that you're noticing the texture improvements in your grey hair around the temples. And it's wonderful that you're also observing a slowdown in new grey hairs appearing over time. That's exactly the kind of gradual progress many of our customers experience as they continue with consistent use.

    Thank you for being part of our community for a year now and for sharing such positive feedback with us. We're grateful for your patience and commitment to your hair care journey!

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.
