Your hair is made of keratin, a protein that needs amino acids to build and maintain healthy strands. A healthy diet and collagen supplements provide these amino acids so you can promote healthier hair.

Increased collagen in the body can help prevent premature greying of your hair as well as keep it strong and lustrous. It also improves the condition of your skin and nails, both of which are largely composed of collagen.

Premature graying of the hair is a common issue for people over 50 years of age, and collagen may be able to stop it in its tracks. A group of scientists found that collagen has antioxidant properties that combat free radical damage and could theoretically stop early graying.

The best way to get your collagen is from foods like animal bone broth and meats, as well as fish and poultry, but you can also add it to your diet through supplements. Supplements usually come in the form of pills and powder, making them easy to mix into juices or smoothies.

Make sure to select a high-quality collagen that is rich in type 1 collagen from marine or bovine sources and doesn’t contain fishy flavors, MSG or other contaminants. This kind of collagen is better for your hair than lower quality versions, as it can retain water in the body and protect your hair from moisture loss.

In addition, look for a collagen supplement that contains vitamin C, which is another important anti-oxidant that can promote healthy skin, hair and nails. Vitamin C has also been linked to a stronger, more supple scalp and hair follicles.

Reduces thinning and loss of hair: Research has shown that taking collagen peptides can boost the strength of your hair follicles, which is essential for preventing hair loss and promoting thicker, longer locks. In addition, it can hydrate the hair and scalp, which are both important for healthy hair and a shiny appearance.

Replenishes the body’s supply of amino acids: Many people have trouble obtaining enough proteins from their diet, which can lead to thinning hair and breakage. Adding a collagen supplement to your diet can help you meet this daily need, helping to promote a healthy head of hair and prevent dandruff.

Improves the overall appearance of your skin and nails: Garshick says that there is some evidence that collagen peptides can strengthen the skin, reducing fine lines, wrinkles and scars. This may be due to the antioxidant effects, but further research is needed.

Relieves dry, brittle hair: As you age, your body’s ability to produce collagen decreases, resulting in a weakening of the skin and the hair follicles that grow the strands. This can cause hair to break, split, and become brittle.

Getting your collagen from foods can help, but supplements are an even more effective way to ensure that you’re getting the right amount of it. Try to find a high-quality, natural, grass-fed collagen peptide that is free of MSG and USP/NF compliant.
