Hair loss treatments aren’t always effective, but mounting evidence shows certain vitamins and nutrients may be important for hair growth. Hair is made almost entirely of protein, so it makes sense consuming enough of it is important for hair growth.

Animal studies show protein deficiency may decrease hair growth and even lead to hair loss. 

But in Western countries, protein deficiency is extremely rare.

The British Nutrition Foundation (BNF) says for adults, an average requirement of 0.6g of protein per kilogram body weight per day is estimated.

The Reference Nutrient Intake (RNI) is set at 0.75g of protein per kilogram body weight per day in adults.

This equates to approximately 56g/day and 45g/day for men and women aged 19-50 years respectively.

The BNF adds: “The average daily intake of protein in the UK is 88g for men and 64g for women, which is more than sufficient: it exceeds the Dietary Reference Values for protein.

“Foods vary in the amount of protein they provide but the main sources include meat, fish, eggs, milk, cheese, cereals and cereal products (e.g. bread), nuts and pulses (beans and lentils).”

Another key nutrient for hair growth is zinc – it plays an important role in hair tissue growth and repair.

It also helps keep the oil glands around the follicles working properly.

According to experts, hair loss is a common symptom of zinc deficiency. 

Studies show zinc supplements reduce hair loss caused by zinc deficiency. 

However, there are some reports supplements with too high of a dose of zinc can also contribute to hair loss.

The recommended daily zinc intake (reference nutrient intake) for an adult man in the UK is 9.5mg.

The recommended daily zinc intake for an adult woman in the UK is 7mg.

And the Department of Health advises intake of zinc should not exceed 25mg per day.

Finasteride and minoxidil are the main treatments for male pattern baldness, advises the NHS.

Minoxidil can also be used to treat female pattern baldness. But women should not use finasteride.

It’s important to note these treatments don’t work for everyone and only work for as long as they’re used.

They’re also not available on the NHS and can be expensive.

If your hair loss is causing you distress, speak to your GP. They may be able to help you get some counselling.
