Supplements can play a key role in supporting hair growth and maintaining healthy hair. While a balanced diet is essential for overall hair health, certain nutrients found in supplements can provide an extra boost, especially when hair thinning or slow growth becomes a concern.

Dr. Janine Bowring, ND, shared five of the best supplements that can help with “crazy” hair growth and get you the hair of your dreams. According to her, protein powder, high DHA fish oil, and iron bisglycinate are some of the best choices. Read on to learn more.
1. High DHA fish oil supplement
High DHA (docosahexaenoic acid) fish oil supplements can support hair growth and improve hair health in several beneficial ways. DHA is an omega-3 fatty acid that is vital for overall wellness, and it plays an important role in promoting a healthy scalp and hair follicles.
This one “really helps with beautiful, healthy, and shiny hair,” she says.

2. Collagen supplement
By providing important amino acids, collagen helps maintain the strength and integrity of hair follicles, which is crucial for healthy hair growth. Stronger follicles can result in thicker, more resilient hair.
“I like a hydrolyzed, bovine, grass-fed collagen,” Bowring notes.

3. Protein powder
Hair is primarily made up of keratin, a protein, which means ensuring adequate protein intake is crucial for healthy hair growth. The ones derived from whey, pea, rice, or collagen contain essential amino acids that are the building blocks of keratin. Without enough protein, hair may become weak and brittle.
“A whey isolate is what you’re looking for,” and she suggests to “get a high-quality one without fillers.”

4. A thyroid-supporting supplement
A thyroid-supporting supplement can potentially help with hair growth, especially for individuals with thyroid imbalances, such as hypothyroidism or Hashimoto's disease.
“If you have a low thyroid function, that’s going to affect your hair growth. So something to support that thyroid in a supplement is really great for that long, beautiful hair," she reveals.

5. Iron bisglycinate
Iron is a vital mineral for many bodily functions, including oxygen transport, energy production, and cell function. Hair growth is directly influenced by the body’s ability to deliver oxygen and nutrients to the hair follicles.
“If you know that you’re deficient in iron, that can cause hair loss, and iron bisglycinate is really easy on the stomach as a supplement and will help you grow that hair," Bowring adds.
