Your hair is changing in two ways at onceGreyer, and thinner than it used to be.

Why hair gets greyer and thinner togetherAnd how Arey's The System treats both.

What you see. More greys, less volume and less shine, all in the same few years.

What causes it. Both start at the follicle. With age, oxidative stress and nutrient gaps wear down the cells that make pigment and the cells that build a strong, full strand.

That's why Arey created The System: a daily supplement with the vitamins, minerals and antioxidants your follicles use, and a scalp serum with the patented Mela-9® Complex that protects pigment and strengthens hair at the root.

MELA-9® COMPLEXMade to protect pigment right at the follicle.

A patented blend of antioxidants, botanicals and a peptide that stimulates MC1-R, the receptor your pigment cells use to make color.

I’ve been using the supplements and hair care products for about 3-4 months now. I am seeing a difference in the thickness of my hair as well as finding previously grey hairs that are now brown at the roots. Amazing!

Karrie G.
★★★★★

I started this system because my hair was thinning and coming out in clumps in the shower, plus if I could slow down or stop the grey that would just be an added benefit. After about 4 months, I have been very happy with my results. My hair is definitely healthier and thicker and I think the grey is beginning to slow down a as well. I plan to continue the System plus keep using the shampoo & conditioner.

I just finished my first bottle of Not Today, Grey and I'm loving the result! My hair looks fuller and each strand feels thicker.

JULIE K.
★★★★★

I’ve been using root serum for 4 months and it’s definitely helped with hair growth plus I’m seeing less grey hair. At 53 years old, I’ve really started to see the grey hairs coming in and this has helped. I’m looking forward to continuing on with this product and even more results! My hair even looks fuller! Definitely recommend!

Lauralee M.
★★★★★

I have been using Arey Root Scalp Serum and the hair vitamins for 5 months straight. This product has worked well. My gray hair has decreased and the existing ones are not as white as they appear. I am purchasing another 6 months and hopefully results continues.

Christina L.
★★★★★

Ive been using the supplement and scalp spray/serum for a few months now (maybe 4 to 6ish, I cant recall). I do feel like it has slowed down the amount of grays coming in. My hair is still mostly dark but but I'll get patches of gray, wirey baby like hairs as I approach 40 and that has slowed down. After a good clarifying shampoo, I do like the serum and my scalp seems hydrated.

★★★★★

I am surprised as how my hair is. I know it is about grey but It is also thicker and has a nice shine. I also love the brush!!!!

Kimberly M.
★★★★★

My hair has gotten thicker and my grays are a little less wirey. I’ve only been taking it three months so looking forward to seeing if I start to see repigmentation with a little more time.

Ava L.
★★★★★

After 2 pregnancies, my hair texture changed (for the worse). My naturally curly hair was just weirdly wavy and frizzy. However, after taking Arey for a few months my curls have become defined again. My hair hasn't looked this healthy in decades. I'm hooked on Arey!

Eleanor K.
★★★★★

I've been using the shampoo, conditioner, vitamins, and serum for 3 months. My hair has less grays and feels fuller. I'm gonna keep with it to see the max effects for using the products for 6+ months

Fatima P.
★★★★★

If you continue to use consistently you will see results. It won’t diminish all gray hair, but it does lessen it.

Monique H.
★★★★★

I am able to see visible repigmentation and few grey hair in my head in 6+ months of usage. But the Grey hair in sideburns are still stubborn. Waiting for the Arey magic to happen. I am using the product daily. Consistent use sure leads to great benefits.

Anitha N.
★★★★★

This is pretty easy to use in hair and makes your hair more lifted at the root after you use it so it makes your hair look more voluminous .

Michele H.
★★★★★

I put it on before I go to bed and surprisingly it does not leave my hair greasy

Janelle G.
★★★★★

I was hesitant to try this, and expected that it would make my hair extra greasy at the roots, but I was so pleasantly surprised! My hair felt refreshed and volumized!

Questions, answered

Will it help with thinning?

In the study, 3× more people saw thicker, fuller hair with more shine than with placebo. The System supports fullness and density; it isn't a treatment for medical hair loss.

Can I use it with my other hair products?

Yes. Layer it with your usual haircare and styling. It's color-safe and safe for all hair types, including textured and color-treated hair.

When will I see results?

Most people first notice healthier, shinier, fuller hair within 1–3 months. Changes in grey regrowth usually show over 3–6 months of daily use, so plan on a full 6 months.

Is The System a dye?

No. There's no dye or colorant in it. It supports your body's own pigment production, so new hair grows in with more of its natural color.

Will the serum make my hair greasy?

No. To The Root® is oil-free and scent-free. It dries with no residue, and you can style as usual.

What happens if I stop?

Greying is a gradual process, so your hair slowly goes back to its natural greying pattern. Think of it like a skincare routine: consistency keeps the results.

Can I change or cancel my subscription?

Yes. Pause, change or cancel anytime. Subscriptions ship free and unlock free gifts on your 2nd, 3rd and 5th orders.
