Had shingles on head, in hair, but it began with an odd red welt looking like a mosquito or spider bite on my neck (painless, itchless). They say if they diagnose it within a day or two, from this welt, they have a treatment to lessen it. I have my doubts, though. Acupuncture through an acupuncturist/herbalist that knows Chinese herbs would be something I would try right away, also, if living where there was one.
I tried apple cider vinegar on it once, but it did not work. The scalp was soggy already. I used rose water which gave temporary (only) relief. Getting a bonnet for your blow dryer to dry it if usng Apple Cider Vinegar would be a plus. Maybe internally, but I feel if I had not been run down and maybe short on vitamin c and others, but stressed and run-down from the stress, it would not have taken hold in my case. Drying the scalp might have helped, Also, to protect hair follicles, taking remedies and vits. to help hairloss if it occurs later. Then, getting to bed early can do wonders to combat being run down. Hair-skin vitamins.
Vitamins for hair are a must if it is on the head. I made the mistake of getting the new shingles vaccination about 2 years later. That was about the time I started losing hair. The vaccination made me feel a little like I had it again. I cannot blame my hair loss all on one thing. It could have been partly from vit. C deficiency and Fukishima fallout. It has been largely stopped with vitamin and even culinary herb supplements and oil treatments (castor oil). Also, plus various things I can do to increase circulation in the scalp.
The vaccination for it was probably the final straw as far as the alopecia coming on. I would definitely not ever take another.
