I have treated quite a few children and teenagers but not many males around 20. I have a 10 year old girl now with alopecia but she is only 2 weeks in, so I cant tell much; other than that she is given iodine, borax, vit c and b, zinc and magnesium.
I have a hair do for you, cheap and effective;
mix one heaped tablespoon of Borax in half a liter of warm water, add 10 drops of Iodine and 10 drops of essential oil
(rosemary, tea tree or lavender or a mix of these) dont worry the solution will turn transparent / borax fade the Iodine color. I believe the inflammation have no chance toward this scalp mix.
Pour in a squeeze bottle and add some to your scalp, let it sit for half an hour or so. Then shampoo as usual.
