You don't need any expensive creams. Just go get Selsun Blue either name brand or generic (both work but one is cheaper). I use the 2.5% but it comes in a 1% too I believe and it works fine (my Dr. recommended it to treat it). If you use the higher dose, you must be sure to not keep it on for more than 15mins as it can burn the skin in the area being treated. I would suggest using the 1% if you have never treated it before, it will do just fine. Spread a little on the area you have the Tinea and be sure to get all the spots. Leave on for about ten to fifteen minutes then wash off with a warm cloth. Do this once or twice a day (depending on how bad it is) and do it for two weeks. Should clear it right up for you...good luck!
