apple cidar vinegar

Hi guys, I’ve had folliculitis for almost 5 years, and no medicine has really helped me cure it completely. I saw someone on here say that ACV mixed with water helps, but how long would it take to see results? I’ve been using it for 2 days now. Also, i read that ACV can’t be used on the scalp for more than twice a week. Is it safe to use everyday or should i stick to using it twice a week? I’ve also been using African black soap from Amazon for 2 days as well.
