While laser therapy provides the foundation for hair regrowth, dermatologists increasingly recommend a comprehensive approach that addresses multiple factors affecting hair health. Supporting treatments and lifestyle modifications can enhance the effectiveness of primary interventions.
Nutrition as Foundation
Hair follicles require specific nutrients to function optimally. "The best diet for your hair is the same one that's best for your heart, brain, and longevity—the Mediterranean diet, with lean protein, nuts, fruits and vegetables, whole grains, and healthy fats," says Dr. Piliang. Protein is especially important since hair is primarily made of protein.
"If you aren't eating correctly, no matter what products you use on your hair, it simply won't grow to its best ability," notes Anabel Kingsley. Being low in iron, vitamin D, or zinc can contribute to hair thinning.
Dr. Evan A. Rieder, assistant professor in the Ronald O. Perelman Department of Dermatology at NYU Langone Health, notes that "often, people are treated for genetic hair loss when it's actually an iron deficiency that's responsible." Women with heavy periods, those following restrictive diets, vegetarians, and vegans should be particularly careful about iron intake.
The Power of Touch
Daily scalp massage can complement laser therapy by improving circulation. A 24-week study on nine men showed that device-mediated scalp massages for 4 minutes daily improved human scalp hair thickness by 10%, according to research published in *Dermatology and Therapy*. Gentle circular motions with fingertips can be easily incorporated into daily routines.
Some users also incorporate dermarolling—using a small roller with tiny needles to stimulate the scalp surface—once or twice weekly. While the research is still developing, early studies suggest it may enhance the effectiveness of laser therapy.
Hydration and Gentle Care
Many people overlook the importance of proper hydration for scalp health. Using sulfate-free shampoos and ensuring adequate daily water intake supports the scalp's natural barrier function and overall hair health.
The Breakfast Connection
"So many people say their diet is great, but then they admit that they don't have time in the morning, and rush out the door without breakfast," observes Kingsley. She explains that hair receives nutrients only after major organs have been fed, making consistent nutrition throughout the day important for hair health.
Consistency Over Perfection
The key to success with any comprehensive hair health approach is building sustainable habits rather than pursuing perfection. Users who integrate these supporting practices with their laser therapy often report better outcomes than those using laser therapy alone.
