Hair loss? Gut health issues? Dr. Nicole Saphier reveals smart fixes

Thinning hair can be caused by many factors, said Saphier. These include hormonal or metabolic changes, age, medications and stress.

"I had a hard time putting my hair up in a ponytail. It was really upsetting emotionally," she said on "Fox & Friends Weekend."

"It took some patience, but I began seeing significant regrowth and improvement within one to two months of doing this regimen and I haven't stopped!" she told Fox News Digital. 

"My personal experience has continued to reinforce my belief in the power of integrative care."

She said she also put together a collection of liquid natural herbs including gotu kola, horsetail and biotin.

It's important to consult a medical professional if experiencing any issues, she stressed, so that the healthcare provider can find and address the root cause of the issues.

Saphier also discussed gut health.

"Gut health is tied to everything," said Dr. Saphier. 

"But you also have to give yourself prebiotics," she said.

Prebiotics give the nutrients to the probiotics and those good bacteria in your gut. 

They can be found in such things as garlic and blueberries.

"I actually take liquid garlic every single morning," Saphier said.

In terms of liquid garlic vs. capsules, the doctor said that in liquid form, garlic is more bioavailable, meaning the body can absorb and use its benefits more efficiently than with capsules. 

Another important aspect of diet is fiber. Among the best foods for fiber are raspberries, lentils and avocado, said Saphier.

"You do all of that and your gut is going to be as healthy as can be," she said.

What about the impact of stress on hair loss and gut health? The doctor said that stress isn't just a feeling; it's an actual physiological effect on the body.

She also focuses on quality sleep and proper nutrition, she said, as these directly impact energy and resilience.

"Managing stress isn't about eliminating it. It's about finding balance and supporting your body through it," she said.
