## Synthesis

**Gray hair** results from a failure of the copper-dependent enzyme that produces **melanin pigment**, a process Peat linked directly to *copper deficiency* and the competitive displacement of copper by excess iron. [Source 1, 3, 5] He observed that iron competes against copper for incorporation into pigment enzymes, and that an accumulation of iron with aging or from high-iron foods will "knock the copper out" of these enzymes, halting pigment formation. [Source 1, 5, 7] Peat also identified other competing heavy metals, such as molybdenum, as contributing factors. [Source 5, 6] This loss of pigment is not merely cosmetic; Peat connected it to a broader failure of oxidative metabolism, noting that copper is both the respiratory catalyst and the pigment-forming catalyst, so a deficiency tends to produce *lower metabolism* and more inflamed tissue. [Source 3]

The restoration of pigment is possible and can be remarkably rapid when copper is supplied directly to the follicle. Peat described a personal experiment in which he applied a weak solution of **copper aspirinate and copper acetate** (made by dissolving a copper penny in water with aspirin and vinegar) to white eyebrow hairs, observing black pigment appearing at the root the very next day. [Source 1, 8] He found that eyebrows, with a lifespan of about a month, were highly receptive, while only about 10% of longer-lived sideburn or head hairs responded to a single application because they must be in the correct growth phase. [Source 2, 8] However, he cautioned that a solution that is too strong could cause a **mole** to develop almost instantly through an invasion of pigment cells, leading him to suggest safer alternatives. [Source 2]

Systemic hormonal and metabolic factors are fundamental to the graying process. Peat argued that **thyroid function** is a primary regulator, as thyroid hormone governs copper assimilation and the hormones that regulate pigment. [Source 2] He noted that hypothyroidism is associated with high prolactin and serotonin, and that thyroid supplementation is a reliable way to control prolactin, which is linked to hair abnormalities. [Source 4, 7] Dinkov later cited a study confirming that people with prematurely gray hair have a significantly high percentage of low thyroid function and, in virtually all cases, low vitamin D. [Source 9] Peat also observed that **DHEA** could correct graying "pretty quickly," and recommended supplementing it either topically or orally as a safer alternative to direct copper application. [Source 2, 4] Roddy elaborated that the hair follicle has an extremely proliferative metabolism that generates many free radicals; if **pregnenolone**, **progesterone**, or DHEA are deficient, the melanin will accept these electrons and become damaged, leading to pigment loss. [Source 10] Dinkov added that the accumulation of tryptophan and serotonin has been shown to cause gray hair, with a case study reporting reversal of completely white hair using bromocriptine. [Source 9]

Environmental and dietary stressors accelerate the process. Peat linked premature graying to *stress on the skin* from cold climates and radiation, noting that dental X-rays could cause circular patches of white whiskers by knocking out the ability to oxidize pigment. [Source 3] He emphasized that a diet high in iron-rich muscle meats, with its accompanying phosphate, tryptophan, and heme, tends to support degenerative processes and displace copper. [Source 3, 5] To counteract this, Peat recommended consuming shellfish such as oysters, shrimp, and crab as the best food for increasing copper while decreasing iron, and advised drinking coffee with meat to inhibit iron absorption. [Source 4, 7, 8] Roddy observed that the modern environment is oriented against the individual's oxidative metabolism, making premature graying in teenagers and young adults increasingly common. [Source 10]

## People also ask

### How does excess iron cause gray hair according to Peat?

Peat argued that excess iron competes with and displaces copper from the enzyme that produces melanin pigment, effectively halting pigment formation in the hair follicle.

### Can gray hair be reversed quickly with topical copper?

The corpus describes Peat's experiment where a weak copper solution applied to white eyebrow hairs produced black pigment at the root the next day, though only hairs in the correct growth phase responded.

### What role does thyroid function play in premature graying?

Peat argued that thyroid hormone governs copper assimilation and pigment-regulating hormones, and the corpus notes that hypothyroidism is strongly associated with prematurely gray hair.

> **Patrick Timpone:** so along with everything else when we react to things in the world and angst and stress and worry you can lose here over that.
>
> **Ray Peat:** yeah and at the same time your whole health and suffering.
>
> **Patrick Timpone:** well do we know the physiological phenomena going on with the gray and why some people gray early is there any science behind that do we know?
>
> **Ray Peat:** yeah I've thought about it experimented with quite a lot I started getting individual white eyebrows when I was in my 40s and I was thinking about the melanin in the brain of being deficient in Parkinson's disease and thinking about what happens in that process. I realized that an excess of iron competes against copper and copper is the enzyme that makes the the dark pigment. And too much iron will simply get in the way and knock the copper out of out of your pigment enzymes. And I didn't want to try it just eating copper. I made a solution put a penny a real copper penny in a little bottle of water with an aspirin tablet and about half a spoonful of vinegar. So it had two acidic things to help the solvent. So it was copper aspirinate and copper acetate that I was using in the solution and I found I put a drop of that on the white here and watched it closely they grow very very fast. The very next day and very visibly on the second day, I could see black pigment appearing at the root that just essentially an instantaneous restoration of pigment formation.

> **Question:** [Restoring Color to Gray Hair] I emailed Dr. Peat about restoring color to my graying hair a few days ago. This was his response:
>
> **Ray Peat:** Do you know how your thyroid function is? Thyroid regulates copper assimilation, and also the hormones that regulate pigment. I found that applying a weak solution of copper just once would restore color immediately to eyebrows, or to about 10% of sideburn hairs, apparently because the very long-lived hairs have to be in the right phase of growth, and eyebrows, with a very short life, seem to stay receptive to the stimulation. But I also found that a slightly too strong solution could cause a mole to develop almost instantly, with an invasion of pigment cells. I think a safer alternative would be to supplement, either topically or orally, a little DHEA.

> **Patrick Timpone:** interesting any after all these years have you ever seen any quality information on why the hairs tend to lose their color gray why that is
>
> **Ray Peat:** Many years ago, when I taught in Bozeman, Colorado, or Montana, the rate of white-haired, prematurely gray-haired people seemed very high in those very cold towns. And I decided that the stress to the skin was probably a factor. Radiation, when a person has dental x-rays, the whiskers will sometimes turn white in circular areas on the cheeks, a series of overlapping circles. suggesting that the radiation was knocking out the ability to oxidize the pigment. Copper is both the respiratory catalyst and the pigment forming catalyst. So if you're copper deficient, you're going to tend to have white graying hair as well as lower metabolizing maybe more inflamed tissue.
>
> **Patrick Timpone:** What do you think about drinking water out of a pure copper vessel from time to time? You think that's valuable?
>
> **Ray Peat:** Yeah. Getting enough copper in relation to iron I think is the... protective factor so people who eat too much meat or other iron rich food are going to compete and displace the copper that is needed for energy production and pigment formation

> **Ray Peat:** The androgens usually are up, but prolactin excess — the difference seems to be whether the prolactin is steadily high, or whether it surges very high. Both hirsutism and hair loss are associated with high prolactin. The thyroid supplement is a very reliable way to control prolactin in most women. vitamin A and calcium also help to inhibit excess prolactin.
>
> **Andrew Murray and Sarah Johannesen-Murray:** And from a herbal point of view, Vitex blocks prolactin. Vitex — chaste tree berry. And also, progesterone would help with blocking some of those high androgens that are promoting the hair growth in women.
>
> **Ray Peat:** Yeah. And the thyroid, if you have enough cholesterol, the thyroid will increase your progesterone, pregnenolone, and DHEA.
>
> **Andrew Murray and Sarah Johannesen-Murray:** How about graying hair? Most commonly you see that as a sign of aging but not necessarily so?
>
> **Ray Peat:** Yeah, I have seen DHEA correct it pretty quickly. The enzyme that creates the melanin pigment uses copper as a catalyst. Probably the best food for increasing your copper, while decreasing your iron — which competes against the copper — is shellfish. Shrimp, clams, lobster, crab, squid — all of those have a high copper content, not an excess of iron.

Ray Peat · Interview · Nov 15, 2021

> Yeah, lots of people are very happy and healthy when they have a 0.1. Wow, that's amazing, that's amazing. And you've seen on these blood tests where they have their, what do they call it, safe range doctor, whatever they call it. The recommended range is like 4 to 10 or something like that. Oh yeah, that's kind of a subcult. Subcult. If you look at the history of TSH and the theory of how to measure thyroid deficiency, it goes back to what I call a fraud. It's a total destruction of our thyroid understanding, starting in the 1940s. I've got an article called 50 Years of Fraud which superficially traces out the history of how TSH has come to be the defining trait of thyroid function. So that's why to this day you're concerned, what you look at is the TSH and you don't care about the other ones. That's a standard medical opinion. I look at TSH as one of the pro-inflammatory pituitary hormones that is best when it's minimal. Low as you can go, right? Yeah, it's promoting inflammation. TSH goes up in hypothyroidism and things like inflammation of the blood vessels increases because of high TSH, not just because of low thyroid hormone. TSH is an active factor in the sickness of thyroid deficiency. Catherine wants to know, she's in California, could Dr. P discuss the relationship between freckles and lipofuscin, if there is one? Why do young children have freckles? I thought they were hereditary. Why do people with fair skin tones and red hair usually have freckles? You usually have what? Freckles. Yeah, why do red hair and light skin people have freckles? I think partly it's an irritated inflammatory reaction. I've known people who had sort of a pre-cancerous reaction when they were extremely deficient in vitamin D and then got exposed on the background of red hair and very pale skin. They're more susceptible because of the lower pigment deficiency in defense against ultraviolet. Brandon writes in, after all these years, have Dr. P ever come up with an idea of how to get one's natural hair color back if they are gray? Do we know why the hair turns gray?

> **Patrick Timpone:** Brandon writes in, after all these years, have Dr. Peat ever come up with an idea of how to get one's natural hair color back if they are gray? Do we know why the hair turns gray?
>
> **Ray Peat:** Yeah, partly it's that the skin loses or can't retain the copper. an enzyme that produces the melanin pigment and a toxic accumulation of some competing metals such as iron can displace the copper and accelerate the loss of pigment.
>
> **Patrick Timpone:** So it displaces the copper so one might play around with getting more copper in.
>
> **Ray Peat:** And less of the competing metals iron and possibly other heavy metals like molybdenum.
>
> **Patrick Timpone:** And they would come in through what pathway? Foods?
>
> **Ray Peat:** Yeah, just random accumulation of food materials over the years.
>
> **Patrick Timpone:** Interesting. What do you think about drinking water that's been in a copper vessel?
>
> **Ray Peat:** It's okay if it wasn't acidic water. You'll recognize the taste of copper pretty well at a toxic level if the water had low pH.
>
> **Patrick Timpone:** Oh, so what would be an undoable number for you as pH-wise? Five or six?

> **Andrew Murray and Sarah Johannesen-Murray:** I think contrary to popular opinion about shellfish they’re actually lower on the food chain, so they’re lower in heavy metals and other contaminants than fish are. Just from a personal note since I started eating a serving of shellfish once a week three years ago, I haven’t noticed any new gray hairs starting — the same ones that had already started, unfortunately when I was 30, are still there, they haven’t reversed. I haven’t noticed it continuing to spread, so it does work, making sure you get your copper intake balanced. In the form of shellfish it’s quite balanced.
>
> **Ray Peat:** Iron accumulates with aging. If a person is going to eat foods that are very high in iron, such as meat or liver, I think it’s helpful in the long run to have some coffee right at the same time you’re having meat so you don’t absorb all of the iron.
>
> **Andrew Murray and Sarah Johannesen-Murray:** Yeah, iron is a quite damaging ion itself, isn’t it, it’s very pro-inflammatory and oxidative…
>
> **Ray Peat:** Yeah, it attacks and interacts with the polyunsaturated fats, and it tends to increase your serotonin.

> **Ray Peat:** yeah and changed the structure of the cells had invaded the area and as so I just watched it over period of a month that that had leveled out and disappeared but that got me interested in the the phenomenon of pigment cell migration in the skin and that cells, it turns out, that pigment cells can swim through the seemingly solid a structure of your skin they can travel almost an inch a day in warm weather when your skin temperatures around 90 degrees. They can migrate with amazing speed and I found that if I provided them with the the nutrients that they needed, which included copper, that they would that a mole will disperse or move will fade out and go back to being a normal pigmented skin.
>
> **Patrick Timpone:** so interesting so you did the copper, aspirin and vinegar, copper penny?
>
> **Ray Peat:** yeah I found it that on my sideburns only about 10% of the white hairs reverted to black pigment formation after one application and I realized that's because where eyebrows has a lifespan of only about a month your facial hairs and and head hairs live years and any one application is only going to affect a small percentage that are in the right phase of growth.

> **Danny Roddy:** I'm a little rusty on this, but the Milano sites are real sensitive to reductive stress. And the hair follicle is very proliferative. And I think if there's a deficiency... of pregnenolone, progesterone, or DHEA, the melanin will start accepting electrons that the melanocytes are producing and it will damage them and it will lack pigment. Does any of that sound right to you? A couple of things.

> **Caller:** How's it going? Yeah. So as far as like graying error, I know you did the ball and stuff, but like what about grain or do you have any thoughts on that? Like, you know, I'm I'm in my mid thirties. It's about time anyway. It's coming in. But I'd like to, you know, push it back a little bit if possible. But when you're looking online, Reddit, there's a lot of people going gray and they're like even at like 18 and the 20s. So. Yeah. Do you have any thoughts on that? Like I hear some people talk about, you know, like a lot of people like the carnivore keto space kind of, you know, I think those kinds of diets can help. I know you're not into that kind of stuff at all, but also things like spermidine. I don't know what you told us on that. Just in general on grain.
>
> **Danny Roddy:** My understanding is that hair follicle has extremely proliferative metabolism, meaning that it creates lots of free radicals. And I think in the growth process, if things like thyroid and pregnenolone, progesterone, DHA are not there to quench the free radicals, the free radicals can be donated to melanin as essentially a free radical quencher. And that can cause the loss of the pigment. And so I wrote an old article about this, not specifically about gray hair, but it does touch on the subject. It's on my sub stack. And yeah, but I think it would just represent a lack of oxidative metabolism in the individual. But at the same time, it's like, like what I just talked about with the last person, like the whole environment is kind of oriented against the person. And so I would not be surprised that like 18 year olds or even younger than that are going gray. I like, even with these vaccines, I bet baldness will get younger and younger. When I worked at Apple, I remember talking to some old person there while I was fixing their computer. And he was mentioning how many young, like 20-year-olds were balding in the store. And he thought it was totally weird because he's like an older boomer. But he thought that baldness usually occurred at 50 or 60 years old, but it was happening in 20-year-olds. So now with the vaccines and how poor the environment is, I bet it will get even younger. yeah anyways the copper i think i'm a little rusty on this i've not looked into it for a long time but copper promotes like catalase and that's something to protect cells protect melanin so copper you'll probably read a lot about copper helping to keep hair color or restore it but thyroid and copper have a very close relationship and there's lots of papers about restoring hair color with thyroid and so those are the two things that i think of immediately
