oh gosh Candie, Im so glad you have asked this.
Mine has been itching non stop, and I havent got nits either, although my kids did both have nits a few months ago, and Ive been convinced that I had them but have used all the nit treatments, and constantly combing my hair with the nit comb and not found a single thing.
My head is really itchy, and my hair is still coming out too. Would love to know if anyone has an explanation.
