I agree my concealer (Toppik) and the "full hair confidence" can be addictive. I only use once every couple months on special occasions. Also try and keep it on very limited time to below 6 hours.
I did get clumps once when I put too much concealer on hair that was not cleaned in 2 days...
I am 51 years old with very pale white skin with real dark almost jet black hair that is curly and thick. Unfortunately I dont have gray hair yet to get better contrast with my pale skin. I have thinning loss of hair in the front that I would like to get transplant with around 2500 hair...
