Do supplements help hair growth? It’s a question likely to be asked by many, considering the millions of dollars spent by Amercians each year on treatments to prevent hair loss – and even to encourage new growth.

As the market continues to develop, it’s wise to look into the claims that are made by the dizzying variety of products.

Dr. Ross Radusky, a board-certified dermatologist at the Dermatology Treatment and Research Center in Dallas, says that “people always look for one magic pill to solve hair loss” but “the answer is, that there is no magic pill”.

“There is nothing that is going to bring your hair back completely – yet,” he says. “There is obviously more research being done, but hair loss supplements can play an important part in complementing a robust treatment for hair loss.”

Of course, if you are struggling with hair loss, or looking to introduce a new supplement (such as the best multivitamin for women) to your diet, it’s always best to consult your doctor first.

How does diet affect hair loss?

“We’re missing certain nutrients that we need, like certain B-complexes, D-complexes, zinc, calcium and turmeric, which is an anti-inflammatory supplement,” he says. “So, looking for those ingredients in a hair loss supplement helps. What you’re eating is going to help grow your hair to its fullest.”
