Your diet is hugely important when it comes to the health of your hair, for many reasons. Both deficiencies and excesses of certain things in your diet can result in hair loss. For example, in our London and New York Clinics, we often see hair loss caused by iron and ferritin (stored iron) deficiency. On the other hand, we have also seen hair loss resulting from an overload of Vitamin A (found in foods such as oily fish, liver and cheese).

When it comes to the best foods for hair growth, we suggest including at least a palm-sized portion of any protein (like fish, chicken, lean meat, eggs, quinoa, nuts or pulses) together with a portion of complex carbohydrates (such as whole wheat toast, skin-on potatoes, oats, barley, brown rice or pasta).
