Could Ingredients in Concealers Lead to Cancer?

Just a general question to Dr. Rassman or any other doctor on the team. Regarding these topical fiber hairloss concealers such as toppik or HairSoReal I was concerned about 2 things.

1. Is the silica contained in them. I understand breathing in crystal silica can lead to silicosis and bronchogenic cancer, do you think the silica contained in these products can have a similar effect?

2. The D and C and FD and C colorings they use are FDA approved but do you think constantly using these products in your hair (where some might fall to the scalp) will lead to scalp cancer?

Thank you!

These camouflaging agents aren’t problematic if used correctly, but inhaling them in excess (either in a spray or in a powder that goes all over the place) could certainly cause problems. Generally speaking, the amount and type of silica found in cosmetics isn’t harmful… unless you happen to have an allergy to it.

I can not imagine that these concealers are carcinogenic to the scalp.
