Ammonium Chloride in Toppik

Hi there. Is the Ammonium Chloride in Toppik safe for us to use? To be honest, I don’t ever wash the stuff out. I just leave it in and keep adding more. I have much less hair than it appears. But, I worry about this ingridient seeping into my bloodstream from my scalp.

It seems that Ammonium Chloride is part of the formulation for many shampoos and some hair loss products, like Toppik. I would assume that it is safe, as product safety is under the auspices of some governmental agencies that would have restricted the use of Ammonium Chloride had any major negative reports come in. But, as I can not answer you with any authority, I would suggest that you write to the manufacturer of Toppik and ask them. Many people who use Toppik do not regularly wash it out. If you are concerned about the safety of the product, then stop using it, or at the least wash it out every night.
