What’s collagen?
To understand how collagen might have an effect on your hair, you first want to know how naturally occurring collagen works. That is the stuff our our bodies make, and its essential function is the explanation so many producers are leaping on the collagen-supplement bandwagon.
Collagen is a fibrous, supportive protein that makes up bones, tendons, cartilage, ligaments, and pores and skin. Its robust and versatile constructions help and anchor cells to one another. Collagen is what cushions joints and makes pores and skin plump.
Our our bodies create collagen by breaking down protein from meals into amino acids. Dairy, eggs, and cheese are all good sources of collagen-boosting protein, as are plant-based proteins from meals like beans, nuts, seeds, quinoa, tempeh, and tofu.

Why collagen for hair is so interesting
Once you’re youthful, collagen manufacturing is plentiful. It quietly works within the background to maintain our pores and skin agency and wrinkle-free, our muscle groups robust, and our joints versatile.
The catch: Collagen manufacturing slows as we age. Different components contributing to the decline in manufacturing are radiation from the solar, smoking, and different oxidative stress, corresponding to publicity to harsh cleaners and chemical substances, air pollution, diets excessive in fats and sugar, and consuming an excessive amount of alcohol.
When you hit your 20s, collagen begins to lower by 1 p.c a yr. By your 40s, you’re in all probability effectively conscious of the indicators of decrease collagen ranges: wrinkles, looser pores and skin, much less flexibility within the joints, and perhaps thinning and graying hair. That’s when collagen dietary supplements begin tempting us. They promise to plump pores and skin, erase wrinkles, enhance joints, and repair thinning, dry, or brittle hair.
The function of collagen in hair
So, the place do the guarantees of collagen-infused merchandise originate—and the way can they declare to show lackluster hair into the stuff of shampoo commercials? There are a few theories.
The center layer of your pores and skin (known as the dermis) is about 70 p.c collagen, which is one supply of the claims. A wholesome dermis may produce more healthy hair—however that’s a concept. And don’t overlook that the roots of your hair are discovered within the dermis, not the strands you shampoo, situation, and shade.
“Collagen will not be a element of hair,” says dermatologist Shari Lipner, MD, affiliate professor of medical dermatology, Weill Cornell Medication, New York Metropolis. “The primary element of hair is keratin—about 95 p.c.”
That results in the second concept, which is that to make keratin, your physique borrows just a few amino acids from collagen. Having loads of collagen obtainable would in concept assist your hair, however once more there’s no proof that swallowing collagen improves or will increase the manufacturing of keratin.
What the science says
To date, right here’s what the science, albeit restricted, says about taking collagen for hair.
(Listed here are some collagen powder advantages to know.)
Can it enhance hair development?
In a small research revealed within the Journal of Medicine in Dermatology, 26 ladies with hair loss took 4 capsules containing collagen and different vitamins each day for six months. On the finish of the trial, that they had extra hair development than 14 different ladies who had taken a placebo.
That doesn’t imply collagen boosted hair development, although. As a result of the capsules contained extra than simply collagen, there’s no strategy to know which ingredient helped. (The complement additionally included herbs, keratin, and capsaicin.) It could be that the mixture led to development. It’s additionally price noting that the research was partially sponsored by the maker of the collagen complement utilized by members.
One other main caveat: Collagen in merchandise will get damaged down into amino acids, which the physique absorbs like some other protein or amino acid—they don’t essentially go to the areas the place they is perhaps wanted. “The amino acids might contribute to hair development, however there may be restricted proof to help this,” says Dr. Lipner.
Can it shield growing old hair?
Collagen merchandise typically promise to help collagen ranges as they lower with age. Though collagen isn’t a direct element of hair, it’s within the hair roots, which can trigger the hair to skinny as we age. In concept, collagen merchandise might recharge the cells within the dermis to help the roots, which can end in much less thinning hair. However once more, it is a concept—not precisely actuality.
“Collagen is a big molecule, and though you may attempt to apply it to the pores and skin, there’s no proof it might be capable of be absorbed via the pores and skin or hair,” says Houston-based dermatologist Rajani Katta, MD, who additionally serves as volunteer medical college at Baylor School of Medication and McGovern Medical Faculty at UT Well being.

Do you have to use collagen for hair development?
Neither Dr. Lipner nor Dr. Katta advocate collagen merchandise, citing a scarcity of proof to help their use. A greater answer, says Dr. Katta: add protein to your weight-reduction plan. “The amino acids present in collagen dietary supplements are additionally present in numerous meals, which implies you could have different methods you may assist your physique get these amino acids,” says Katta
In the event you nonetheless need to give collagen hair dietary supplements a strive, perform a little research on the corporate that makes them. Generally, specialists agree most dietary supplements are protected, however dietary dietary supplements—together with collagen dietary supplements—aren’t regulated by the Meals and Drug Administration.

You may discover your scalp is drier as you age, which is completely regular. Chemical remedies (like overlaying these grays) may make the hair drier.
“Once you wash your scalp, focus the shampoo in your scalp fairly than your hair for maximal shine,” says Dr. Lipner. “It is very important use conditioner following every wash. Conditioner improves shine, decreases static electrical energy, and will increase energy.”
