Review (1/5): The formula has changed and product is now completely useless!
I have been using this product for many years, (bought it at a beauty supply house before it was available on Amazon), and always have some on hand. It has always worked perfectly on my sparse brows. There would be some staining that would wear off in about a day, but after leaving the cream on for 5-10 minutes the color would last for about a month. The kit I purchased in July on Amazon, however, is absolutely USELESS! I noticed that the capsule was a much darker color than usual, but didn't think much of that. I followed the process I've been following for nearly a decade, but no matter how long I leave on the cream (powder mixed with the developer), it wipes completely off and ABSOLUTELY NO COLOR is deposited. All I can think of is that the formula was changed. It's so disappointing when a trusted product no longer works, and I can't return this kit because I stock up, and now the 30 day return window has closed. On the hunt for a replacement, I'll report back if/when I find one.
