Have you used silk or satin pillow slips too ? Cotton ones also dry out hair and can snag hairs in the [comparatively] `rough` fibres ...it`s early for `normal`shedding though....so it`s got to have a cause, especially as it`s only on one particular area of the system. I use Enhance conditioner but not even daily and I don`t get shedding [touch wood ! ] Sounds like you`re not being harsh with it [ not frequently shampooing etc.] Something is triggering it though....I always use knot sealer after about the first week`s wear... I reckon it`s drying out as you`ve not been using leave-in conditioner..try the Enhance one--it`s really nice and kind to the hair.These are the makers of it..it`s the third one down and they are in USA... it`s also very inexpensive
