Hair loss can happen for many different reasons. If you’re experiencing hair loss, it could be due to genetics, age, diet, stress, or hormonal imbalances. Regardless of the reason, hair loss can be frustrating. Luckily, there are plenty of interventional products and resources available that may help. Aside from things like hair growth oils or hair growth serums, there are also a host of supplements on the market. Many contain collagen, one of the most abundant structural proteins naturally found in your body. In fact, it accounts for 30 percent of your body’s protein, according to the Cleveland Clinic.
Collagen helps stimulate fibroblasts in the skin, encourages cell turnover, and helps skin and hair maintain strength and elasticity. Like all proteins, collagen is made of several different amino acids. “The most abundant amino acids in collagen are glycine, proline, hydroxyproline, and arginine, which are crucial for maintaining the health, elasticity, and strength of skin and hair,” says Dr. Dusan Sajic, a board-certified dermatologist. Since collagen is so good for hair and skin, it makes sense that collagen would be put into supplements or blended in powder form into smoothies.

But don’t think that adding a collagen supplement into your daily routine will be a silver bullet for your hair loss woes, particularly since the collagen found naturally in our bodies decreases with age. “As we age, not only do we produce less collagen, but we also lose excessive collagen due to environmental stressors like UV exposure, smoke exposure, and poor health habits,” says Shannon Augustine, board-certified aesthetic nurse practitioner. Think of collagen as a preventative measure that may help boost hair growth. If you’d like to try collagen for hair growth, there are plenty of supplements out there, from pills to powders to liquids. Ahead, find our favorite collagen supplements for hair growth out there.

What is collagen and how does it help with hair growth?
Dr. Sajic tells ELLE.com that collagen is a protein formulated with amino acids that provide structure, elasticity, and strength to both skin and hair. “Altogether around fifty-six percent or more of the amino acids in collagen are foundational for skin and hair proteins, and thus has a great ratio that will contribute directly to hair health and vitality,” Dr. Sajic explains.
However, it’s essential to understand that while collagen can certainly help to solve some of your hair problems, maintaining a healthy diet is equally important. “Optimal hair health also requires a more comprehensive approach, including other proteins, vitamins, minerals, and care practices,” Dr. Sajic says.
What are the other benefits of collagen?
Although collagen is widely recognized for its ability to promote healthy hair and skin, this abundant protein also plays a crucial role in other bodily functions including joint health and bone health. “Collagen assists in maintaining the integrity of cartilage, which is essential for healthy joints, and it helps to maintain bone density, which is crucial for preventing age-related bone issues like osteoporosis,” Dr. Sajic explains.
If you’re looking to target these areas of your body, or simply interested in a supplement that provides a cohesive approach, it’s worth incorporating collagen supplements into your daily wellness routine.
Also to note, some collagen supplements are infused with additional nutrients that help to nourish the body. “Collagen supplements may also include vitamins like vitamin C, zinc, vitamin B, and omega-3s which further support your body and health,” Augustine says.
What are the side effects of taking collagen?
So, we’ve heard about all the wonderful benefits of collagen but are there any side effects? Dr. Sajic shares that although collagen is generally safe for most individuals, there are a few things to note. “Some may experience side effects like stomach discomfort, a bad taste or possible allergic reactions,” Dr. Sajic says. “It’s essential to choose high-quality collagen supplements and consult with a healthcare provider before starting any new supplement regimen,” he adds.
To avoid allergic reactions, or any added ingredients that might not sit well with your body, Augustine also suggests taking the time to thoroughly read the ingredient labels.
Are there any reasons in which you shouldn’t take collagen?
“You should always talk to your health care provider before taking any oral supplements or medications,” says Augustine. She also explains that consulting a healthcare professional is especially important if you are taking daily medications or have serious drug or food allergies.
Dr. Sajic shares that those with fish, pork, or bovine allergies should avoid collagen, as many collagen supplements are derived from these animal sources. “It’s also important to talk to your doctor if you have liver or kidney disease, as the excess protein may put extra stress on these organs,” he adds.
Is there any difference in taking collagen in the form of liquid, powder or capsules?
Collagen supplements exist in many forms— including liquid, powder, and capsules— but they all have relatively equal effects. "There are not enough non-bias studies to suggest that one is better than the other,” Augustine shares.
At the end of the day, it simply boils down to your personal preferences, lifestyle, and dietary restrictions. “Liquid collagen can be consumed directly or mixed into beverages, while powder can be added to smoothies, coffee, or baked goods,” Dr. Sajic says. If you would prefer not to mix collagen with your food or drink, you can always take a capsule. However, Dr. Sajic notes that depending on the capsule, it might not be absorbed as efficiently as other forms of collagen.
How frequently should you take collagen?
“For most people, collagen should be taken once daily,” Dr. Sajic says. “Dosage can range from 2.5 to 15 grams daily, depending on the individual’s age, health, and specific skin or hair concerns.” And as with anything, patience and consistency is key, so make sure that you keep track of your collagen intake. “It may take several weeks, if not three to four months, for you to start noticing the benefits of collagen supplements,” Dr. Sajic adds.
