Experts Reveal the Best Collagen Products for Hair Growth

There’s no shortage of collagen products that promise to improve your strands. But which ones actually deliver? We reached out to some of the top hair experts to discover the best collagen for hair growth.

As you are likely already aware, collagen is incredibly beneficial for your locks.

“Collagen is an essential building block of strong hair,” says Dr. Melissa Anzelone, ND at Nutrafol. “It provides proteins and amino acids to make keratin, which is the protein that constructs your hair. Collagen promotes scalp elasticity and moisture. Preserving collagen stored in the scalp helps maintain healthy hair growth.”

So if you’re hoping to lengthen your tresses, start by adding more collagen into your diet. The products below are your best bet to achieving the hair of your dreams. See why the experts recommend them now!


Every expert we spoke with recommended Nutrafol as one of the best collagens for hair growth.

“One product I recommend to my hair loss patients frequently is Nutrafol, a supplement available over-the-counter that contains many natural ingredients that assist with hair growth,” Bay Area dermatologist Dr. Kaveri Karhade shares. “Nutrafol has been shown in some studies to be as efficacious for hair growth as minoxidil, the current leading FDA-approved topical for hair loss. In addition to ashwagandha for stress hormones, and antioxidants, Nutrafol contains hydrolyzed marine collagen, which the brand purports helps ‘rebuild the structural integrity of the hair follicle environment.’”

“Nutrafol provides full metabolic support to optimize your body’s production of hair proteins,” says Dr. Julie Russak of Russak Dermatology NYC.

“Nutrafol is a hair growth supplement that features a patented Synergen Complex® blend of concentrated botanicals that address the multiple root causes of thinning hair: hormones, stress, environment, metabolism and nutrition,” notes Dr. Anzelone. “The collagen in Nutrafol provides essential building blocks to create keratin proteins for healthy hair growth. I love that Nutrafol’s marine collagen is sustainably-sourced from wild-caught cod fish in the cleanest waters of the North Atlantic ocean. Marine collagen from cod fish scales is clean, toxin-free, and reduces food waste.”

Vital Proteins

Vital Proteins is a great product to start with if you’re having trouble getting the recommended amount of protein.

“The easy-to-consume powder that provides a source of 20 grams of collagen per serving,” mentions Dr. Anzelone. “For women, many experts recommend at least 60 grams of protein per day. This product is a great way to start your journey towards that 60 grams.”

Garden of Life

“These collagen products are made from grass-fed animals, which research has shown may have a higher nutritional value,” Dr. Anzelone mentions. But the benefits don’t stop there.

“Many of Garden of Life’s collagen blends have added ingredients like turmeric to support a health inflammatory response or antioxidants like cranberry to fight against damaging free radicals,” she shares.

NeoCell supports hair growth by helping repair your gut. A healthy gut promotes healthy hair.

“NeoCell provides building blocks to heal the gut, to improve nutrient absorption, and therefore, directly and indirectly, improve hair growth,” shares Dr. Russak.

Philip Kingsley Elasticizer

Consultant trichologist Kate Holden of the Kate Holden Clinic mentions that improving hair growth with collagen is more about your diet. Still, she’s a fan of the Philip Kingsley Elasticizer.

“Philip Kingsley’s famous Elasticizer contains hydrolyzed elastin, which is marine collagen derived from fish skin. Commonly, bone broth and fish skin are said to be the best sources of collagen,” she notes.

Vitamin C

Ingesting these collagen products is useless if our bodies don’t absorb them. This is why Kate recommends taking vitamin C.

“Some research suggests we may break down collagen during digestion. So to help our body synthesize collagen directly, vitamin C is essential. Make sure you’re eating lots of colorful fruits and vegetables like peppers, broccoli, tomatoes, oranges, and strawberries.”

“Zinc is also an important factor” to improve collagen absorption, Kate points out. She shares that some “good sources of zinc are meat, dairy, whole grains, fortified cereals, and legumes.”
