I'm sure there are more...
Please start reading the lables of the products you use. Petroleum (or Petrolatum) Jelly is a by-product of crude oil...It has no business being used for our bodies...I don't care what "grandmama" said...Vaseline, do-gro, all that mess...

Carol's Daughter Healthy Hair Butter (http://www.carolsdaughter.com/)
