I am a 73 years old female and a great beneciary of your channel. I have a non-medical problem. During my younger years I applied hair dye to my hair until I was 65 years or so. Now my hair is fully white but for the past few years it is getting a yellow (goldenish) tinge, in particular on the sides and its length. I eat a balanced diet and apply little coconut oil once a week. Shall be grateful for advice.
