Preserves Pigment | Reduces Shedding | Stronger Hair

A skincare-grade shampoo that addresses the early signs of aging hair. Wash preserves pigment while gently cleansing and balancing the scalp for soft, shiny, buildup-free hair. For best results, use consistently for 3–6 months.

WHAT IS IT?

 

Wash is a shampoo that treats your scalp like skin by removing oil and product buildup without stripping essential moisture. Powered by our patented Mela-9® Complex, it works at the root to help preserve natural pigment while a light, creamy lather rinses clean for soft, balanced hair. Gentle enough for daily use and never heavy; pair with Smooth Conditioner or Masque Deep Conditioner for added hydration. Use 3–5× per week; most see softer, stronger hair with less grey hair growth in just 3–6 months with consistent use. Color-safe, dermatologist-tested and hypoallergenic.

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

HOW TO USE

 

1. Apply to scalp and roots, massaging in and lathering.
2. Leave on for a few minutes, then rinse thoroughly.
3. Follow with Smooth Conditioner (for fine to medium hair) or Masque Deep Conditioner (for medium to coarse hair).

Use 3–5 times per week for maximum results. 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.

STUDY RESULTS

 

After using Wash Shampoo and Smooth Conditioner:
94% reported improved hair (at 16 weeks).
83% said hair felt softer.
77% reported fewer new grey hairs.

Based on a 24-Week Consumer Perception Study to assess the efficacy of Arey Wash & Smooth on hair health and greying on 36 male & female participants ages 22-50, all with 30% or less grey, by an independent research team.

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.

Why 'Wash' is Your Key to Less Grey, More Vibrant Hair

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

    Noticeable Difference

    After about 6 months of using this shampoo, my hair dresser told me it looked like I had a lot less greys - and I didn't even tell him I was using this shampoo! Will continue to use.

    Definitely keeping it in my routine

    I wasn’t sure at first, how I was gonna feel about it, but my hair has never been healthier. That includes my scalp as well. I do use the scalp scrub on days that my hair is oily. I’ve noticed less grays since starting using the shampoo instead of just relying on the serum.
