Hi Barb, Over a year ago we were on an extended trip to the coast when suddenly developed severe scalp itching which I'd scratch til made sores and continue to scratch so they got bigger and bigger.nearly drove me up the wall. Went thru all OTC shampoos etc I could find plus an assortment of rxs fm dr and dermatologist and nothing they tried worked. But because of all chems in this stuff my hands had allergic reaction so went to rubber gloves when washing hair etc and ran headlong into to Latex and found out what you're talking about. So now make sure the gloves aren't latex. By the way still have scalp problem after all this time and many $s but at least it's better and callouses on finger tips are going away.....doesn't seem like I ever do anything the easy way--whatever the results are supposed to be I do something different guess I'm a wrong-way-corrigan! Didn't mean to get so wound up, guess just needed to vent. 'Anyhow, thanks for caring and listening. Billie Cook
