While contending with bald spots and thinning tresses is stressful, there is hope:
Hair is a protein fiber (as are nails), which means you need to eat protein to grow new strands and keep the existing ones strong. Protein is also required to produce keratin, a key structural component of hair.
A smart choice is marine-based protein, like salmon, which has been shown to boost hair health in women thanks to its omega-3 fatty acids and vitamin content.
When used as a topical treatment, honey can improve the look of thinning hair. In a study of patients experiencing seborrheic dermatitis, which includes scaling, itching, and hair loss, those who applied a solution of 90% honey and 10% water to their scalp every other day for 4 weeks reported an improvement in hair loss at the end of the study.
Some of the most promising research on reversing female-pattern hair loss was released in January 2015 in the Journal of Cosmetic Dermatology. Subjects in the study received a nutritional supplement containing omega-3 and omega-6 essential fatty acids and antioxidants for 6 months. The results were overwhelmingly positive: After 6 months, 90% of the subjects reported a reduction in hair loss, 86% reported an improvement in hair growth, and 87% reported thicker hair.
To achieve similar results, eat nuts and seeds high in omega-3s and omega-6s, like walnuts, flaxseed, and oils such as grapeseed, sunflower, and sesame.
