A dry, scaly scalp could be a sign that you need more fatty acids, according to nutritionist Dr Marilyn Glanville.
Avocado, seeds and nuts, oily fish and cold-pressed flaxseed oil were all good sources of fatty acids, and could help to prevent balding, she added.
“As most of us know, fat is not all bad, and the essential fats have many vital roles in the body including maintenance of healthy skin, scalp and glossy hair,” said Glanville.
Omega 3 fatty acid supplements, which cost about £1 a day, could also promote healthy hair, Glanville said.
Fruits and vegetables will also fortify your hair against any balding, according to nutritionists.
We need lots of different nutrients for healthy hair, and there isn’t a single food that will protect against hair loss, said nutritionist Cassandra Burns.
A combination of lots of different foods was the best way to protect against balding, she said.
“For the best general protection, focus on eating real foods as they are best natural source of vitamins and minerals,” said Burns.
“Real foods are those in their natural state – vegetables and fruits, unprocessed meats and fish, eggs, whole grains, beans and pulses, nuts and seeds.”
Hair loss could be caused by poor circulation to the scalp, Burns said.
That means fewer nutrients are available for hair follicles, and could lead to balding.
Burns said: “Vitamin C and bioflavonoids in fruits and vegetables support healthy blood vessels, so make sure you get at least your five-a-day, if not seven or 10!
“Spices such as ginger, cinnamon and cayenne can also stimulate the circulation and are great winter warmers to boot.”
The average person loses between 50 and 100 strains of hair a day, according to the American Academy of Dermatology.
Hair grows the fastest from ages 15 to 30, and then slows down between 40 and 50.
More than half of men suffer with pattern baldness by 50 years of age, according to the NHS.
Tablets, lotions and transplants are the current treatments for hair loss, it added.
