Woo hoo! Congrats on your first taste of life in silk lane!! 🙋💆so as far as it drying out it's really not an issue, here's a pic of a root application I applied as normal left 10 mins then went through to check for any missed bits and it was all fine, equally as wet as when I applied it, it lifted perfectly too, I usually use schwarpskopf vario for on scalp which is really good so was a bit worried it wouldn't be as good, it was great tho! only downside was I had to scrape the bowl to finish the whole head out of 1 application worth (1scoop to 35ml developer) 2 lots would have been far too much in the bowl and I'm not brave enough to measure by eye when it comes to new products and at that price waste not I say! I diddnt cover with a cap I just let it develop in the air at room temp (prob a lot colder here than where u are!) I think it states in the instructions not to cover it too

As you can see there was minimal overlapping too which I normally panic over but it was in gorgeous condition afterwards!
