Hello,
Before using coal tar shampoo it is best to discuss it in detail with a dermatologist. Coal Tar Shampoo may stain hair, skin, and clothing. Apart from this, itching, burning, tenderness, or redness; sensitivity to sunlight are the frequent side effects. It can even cause severe allergic reaction in some.
I hope it helps. Take care and regards.
I have not read that; I am not aware of that.
I have used it myself, but that was years ago. It works well.
What's this I hear on the internet about coal tar being carcinogenic? Is that true?
As long as you have no allergies for coal tar it is safe to use. Use as directed though.
