I have this feeling. Usually after I eat trigger foods or if my scalp is sweating. I started losing my hair at the beginning of 14 years old and I'm now 20 and I still have it. I have been doing every test imaginable for curing this and I think candida is the cause.
Try those foods and see how you feel. I've spent probably around 2000 dollars in vitamins, medications, doctor visits, blood samples, and I can probably save you a lot of time. If any of those examples listed are the case please e-mail me at email@example.com and we can work together to beat this.
