Black coloured foods are used in Traditional Chinese Medicine to nourish the kidneys, promote blood circulation, which in turn help promote healthy hair regrowth. In fact, black sesame seeds (roasted and ground) and mulberries are two of the key ingredients in treating Alopecia (including those that are autoimmune in nature) and other hair related disorders. The winter time is also thought to be the best time to nourish and strengthen the kidneys with these nutritious foods.
Regardless of their positioning, black coloured foods such as wood ear mushrooms (also known as black fungus), mulberries, black beans, black sesame seeds, kelp, seaweed, wild rice and black rice are rich in amino acids (key building blocks of protein), antioxidants (due to the intense colours), and phytonutrients that are essential for healthy hair growth.
I have personally included these ingredients regularly in my daughter’s diet and, along with eliminating highly inflammatory foods, they may have contributed to stronger regrowth (thicker and stronger hair strands instead of thin and brittle regrowth we saw in earlier years).
