Diluting RU58841 for application?

[WanderingOracle]

I have some pre-mixed RU in KGB solution from Anagenic. It's dosed at 1mg/1ml. My issue with application is that it is very, very difficult to get 1ml spread over my entire scalp. I've practiced with water, and I can adequately cover the top, sides and temples of my head with about 2ml, but not 1ml.

I'm wondering if you can dilute a small portion(say 5ml), and mix it with either water, or even ethyl alcohol at a 1:1 ratio so that the original 5mg/5ml is now 5mg/10ml. Will this cause any issue with the product degrading?

I'll probably order the raw powder in the future, but I've got two vials of the pre-mixed solution right now.
