If you’ve been struggling with thinning hair or slow hair growth, naturopathic doctor Dr. Janine Bowring says there’s real hope—and it starts from within. According to Dr. Janine, targeted nutritional support is one of the most effective ways to stimulate healthy, resilient hair at any age.
“Here are the five best hair growth supplements that really work,” says Dr. Janine, kicking off a concise but powerful breakdown of what your body might be missing when hair starts to thin.
The Difference Between Dragging Through Your Day And Feeling Great On Your Feet? These Arch Support Insoles
1. High-DHA Fish Oil
The first must-have on her list is a high-DHA fish oil supplement. DHA (docosahexaenoic acid), a type of omega-3 fatty acid, plays a critical role in nourishing the scalp and supporting overall hair structure. “It really helps with beautiful and healthy and shiny hair,” Dr. Janine explains.
2. Hydrolyzed Collagen
Next up: collagen. Dr. Janine recommends a hydrolyzed, grass-fed bovine collagen supplement. Collagen is a key protein in the body that supports the integrity of skin, nails, and hair. “Collagen is absolutely vital for strengthening hair follicles and encouraging regrowth,” she says.
3. High-Quality Protein Powder
Protein intake is often overlooked, but it’s foundational for strong, growing hair. “Whey isolate is what you're looking for,” Dr. Janine advises. “Get a high-quality one without any other fillers.” As hair is made up primarily of keratin—a type of protein—ensuring adequate protein intake can make a noticeable difference in hair thickness and growth.
4. Thyroid Support
If your thyroid is underperforming, your hair may suffer. “If you have low thyroid function, that's going to affect your hair growth,” Dr. Janine says. She recommends thyroid-supportive supplements, particularly for those who experience thinning along with fatigue or other signs of hormonal imbalance. Supporting thyroid health can be a game-changer for women, especially over 40.
5. Iron Bisglycinate
Finally, Dr. Janine points to iron bisglycinate, a highly absorbable form of iron that’s gentle on the stomach. “If you know that you're deficient in iron, that can cause hair loss,” she notes. “Iron bisglycinate will help you to grow that hair.” Women who are menstruating or dealing with chronic fatigue may be especially at risk for low iron, making this supplement essential.
By focusing on internal health with these five targeted supplements, Dr. Janine emphasizes a holistic path to hair growth that delivers visible results. “These really work,” she says—and her clinical experience backs it up.
