Hi, I have sebhorreic dermatitis and I just began the apple cider vinegar remedy for my scalp...I've done it twice within three days and I just started dabbing lavendar and tea tree oils on troublesome hot spots...I'm just wondering how long it should take for this godawful skin condition to clear up. It's as though my scalp gets gooey and peels off sometimes and is unbearably itchy but I'm able to withstand the burning from the cider and oils. I just was wondering how often and when should I apply these and for how long? My hair is also really thinning. My holistic MD says I have high insulin and cortisol levels, but I'm a thin girl...he also put me on "Thyroid (Armour)" because he says my levels could be higher. I'm just wondering why my hair is thinning so much also. Any help would be immensely appreciated!
