Having never applied a product like this before, I found it very easy to use. I followed the directions and it did not stain my skin or make a mess. I suggest applying for 1.5 minutes to start, then again for 30 seconds if needed. My only complaint is with the color itself. It is described as "light brown" but is in fact more of a charcoal color, as you can see in the attached photo. With no warmth to the color, I find it very harsh with my hair color. However, I may continue to use it because of the convenience and longevity.

Love this stuff!! I am strawberry blonde, with very light eyebrows. I bought the light brown tint. I left it on in 30 second increments, for a total of 2 minutes. I kept thinking it needed to be a bit darker and didn't take the advice of another reviewer to wait awhile in between application increments. So, my brows ended up being a bit darker than I would normally have them. For blondes I suggust leave the stuff on in 30-45 seconds increments, after you wipe it off wait like 20-30 minutes before you try to do another increment, because it keeps getting a bit darker. I'm in love with this product, can't beat the value and the end product!

Like most of the reviewers I've seen, I have the Invisible Blonde Brow. I started getting them dyed probably 15-20 years ago now, but it's always hard to find the right salon if you move around a lot. The price, ease of use, and end result really make this a five star for me, but since there are a few things I don't love, I feel like giving it a four is more honest.

I've used it about 5 different times now. I've been playing around with the timing because I noticed many people saying not to leave it on very long. My invincible blond brows would not take the color, so leaving it on less than two minutes did nothing for me. I tried leaving it on a full three minutes last night and I'm very happy with the result. But despite the fact this is the 'light brown' color, it is definitely made from black henna, so even though it may be lighter than their other products, it is definitely not light.

Using it is easy, but also messy. The dye capsules are hard to break without making a mess. The powder catches on the slightest breath so it always ends up in the cup, on the cup lip, on the counter, in the sink.... But I always get plenty of product to use and the cleanup is a quick swipe of a wet tissue. So this is really just a minor nuisance.

I haven't had a problem with it dying my skin without any protection, but I try to remember to do a quick brow outline in Vaseline just in case. I also have not had any skin sensitivity issues.

The product doesn't last as long as getting them professionally done, but doesn't fade overnight. I'm still using trial and error to see what a good routine will be. This is obviously very dependent on how dark you make them to begin with.

Overall, I think the product does exactly what it is supposed to, is very easy to use, and at the price and convenience, it is completely worth the (very minor) issues it has. I strongly recommend it.

Final color is not the golden brown on the box - it is cool ash brown and can get really dark, really fast! If used carefully, it is wonderful and a great alternative to daily brow pencil or microblading. Works best for me when I use Vaseline around my brows to prevent dying skin and only leave on for about 30 seconds at a time. You will have enough dye from one capsule to repeat the process as many times as you need to achieve the darkness you want. Brows look great, get to save a step every morning - love it!

LOVE this stuff! I have very little actual brow hair, and what is there is very light. About a year ago I had the microblading semi-permanent tattoo done, and while I was happy with the results, it was not only expensive ($600+), the healing process was such a pain (dark scabbing, flaking skin, etc.~ Not how you wanna look when you're busy running around in public w/4 kids!). A year later the ink has faded a ton & im back to filling in w/make up daily. Until now! This product was easy to apply, worked like a charm. After reading some reviews, I first took it off after 60 seconds. I could see a slight difference but I needed more. So I continued to reapply & fill in little spots, each time leaving on for about 2 minutes until I was satisfied. I LOVE the results!!!! And even with very little brow hair, the dye still colored my skin (which I wanted to achieve a real shape). The only complaint I have is that I can't find this product in an auburn or red shade. I used light brown & there is ZERO warmth to it. My hair is ashy brown w/hints of strawberry blonde, so in the future I'll try mixing this w/a different brand to get a warmer tone. The kit came with an angle brush perfect for application, I used a toothpick to stir the mixture in the tiny plastic bowl. One capsule is enough for like 3 people, so in the future I'll only tap out a tiny bit of powder. So worth the money, I'm addicted!!!!
