Why Hair Goes Grey
Every hair follicle contains pigment cells that produce melanin, the substance that gives hair its color. Over time those cells slow down and eventually stop. When a follicle stops making melanin, the hair that grows from it comes in white or grey.
Age is the main driver, but not the only one. Genetics set much of the timeline, and stress, nutritional gaps, smoking, and some health conditions are all associated with earlier greying.
That is the gap Arey aims at. The name comes from the French word arrĂȘt, meaning stop, and the brand positions itself as something you start when you notice the first few strands, not after your hair has already turned.
What the Brand Sells
| Product | What It Is For |
|---|---|
| Not Today, Grey | Daily capsule supplement, two capsules a day with food |
| To The Root | Scalp serum delivering a peptide studied for pigment support |
| The System | The supplement and serum bought together |
| Wash and Condition | Shampoo and conditioner formulated for aging hair |
| Shower Duo | The wash and condition pair |
The supplement and serum are the heart of it. The shampoo and conditioner support texture and scalp health rather than pigment.
Inside the Supplement
| Ingredient | Why It Is There |
|---|---|
| Vitamin D, B6, B12, folate, biotin, pantothenic acid | Nutrients linked to hair and general wellbeing |
| Calcium, iron, selenium, copper | Minerals involved in pigment and hair health |
| PABA (para-aminobenzoic acid) | Studied in connection with hair pigmentation |
| Black sesame seed extract | Traditional use for hair color support |
| Fo-Ti root | Botanical long associated with hair in traditional practice |
The formula is vegan, gluten-free, and cruelty-free, and each batch is tested for purity and potency. It contains sesame, which matters if you have a sesame allergy.
One independent reviewer noted that several of these ingredients have research behind them for pigment support and for filling nutritional gaps tied to greying. The same reviews are clear that evidence on supplements reversing grey hair is limited overall.
The Timeline and the Honest Limits
Arey states that results take three to six months of consistent daily use, and the brand is unusually direct about who it works for.
Repigmentation is only possible on hairs that still hold melanin at the root. Once a follicle has stopped producing pigment entirely, no supplement brings that strand back. This is why the brand describes its ideal user as someone with roughly 0 to 30% grey.
Beyond that threshold, the realistic goal changes from reversal to preservation: protecting the pigment you still have and improving the coarseness and dryness that often come with aging hair.
What Users Report
Feedback is broadly positive. Reviews on retail sites average in the mid-four-star range across several hundred ratings, with common themes of thicker, glossier, softer hair and, for some users, visibly fewer greys.
The critical reviews are just as useful. Some users see little or no change after three months. A few report the scalp serum leaving residue that contributed to dandruff or breakouts, and biotin-containing supplements can trigger breakouts in people prone to them.
That spread is typical of hair supplements: real fans, and real non-responders.
Safety Points to Discuss With a Doctor
- Biotin and lab tests: biotin can interfere with certain blood test results, including thyroid and cardiac markers. Tell your doctor and the lab that you take it.
- Iron: this formula contains iron. Do not add it on top of another iron supplement without medical advice, and keep it away from children.
- Pregnancy and breastfeeding: check with your doctor before starting any new supplement.
- Thyroid, autoimmune, or scalp conditions: sudden greying or hair changes can have medical causes worth investigating first.
- Medication interactions: show the ingredient list to your pharmacist if you take prescription medicines.
- Sesame: the supplement contains sesame, so avoid it with that allergy.
- Scalp reactions: if the serum causes itching or spots, stop and see a dermatologist.
How much Arey Costs
| Plan | Price |
|---|---|
| One-month subscription | About $38.25 a month, from a $45 list price |
| Three-month subscription | About $104 total, roughly $34.66 a month |
| Six-month subscription | About $195 total, roughly $32.50 a month |
Subscriptions ship free, and you can pause or cancel at any time. Free shipping also applies to orders over $100 in the US, and orders ship within seven to ten business days.
Given the three to six month timeline, the three-month plan is the sensible starting point. It matches the period over which results are meant to appear and costs less per month than ordering one box at a time.
Whom Arey Fits
A reasonable try if you are in the early stages of greying, you want to act before more pigment is lost, and you are comfortable committing to daily use for several months.
Probably not for you if you are already mostly grey and expecting a reversal, you want a quick fix, or you are looking for something that works like dye. Coloring your hair is a cosmetic answer with immediate results. This is a slower, biological approach with no guarantee.
Frequently Asked Questions
How long does Arey take to work?
The brand states three to six months of daily, consistent use.
Does it work on fully grey hair?
Repigmentation needs melanin still present at the root. Beyond about 30% grey, preservation is the realistic goal.
Is it FDA approved?
No. Dietary supplements are not FDA approved. Arey’s supplement is made in NSF and GMP certified, FDA-registered facilities and batch tested.
Are there side effects?
Some users report breakouts, often linked to biotin. The scalp serum can leave residue on some people.
Can I cancel the subscription?
Yes, subscriptions can be paused or cancelled at any time.
The Bottom Line
Arey is one of the more honest products in a category full of overpromising. It tells you the timeline, it tells you it works best under 30% grey, and it explains that dead pigment cannot be revived.
If you are catching the first greys and you want a nutrition-led approach, the three-month subscription is a fair way to test it. Take a photo at the start so you are comparing evidence rather than memory, and tell your doctor what you are taking, especially before blood tests.
