  We propose a method to introduce Sudakov effects to the unintegrated gluon
density promoting it to be hard scale dependent. The advantage of the approach
is that it guarantees that the gluon density is positive definite and that the
Sudakov effects cancel on integrated level. As a case study we apply the method
to calculate angular correlations and $R_{pA}$ ratio for p+p vs. p+Pb collision
in the production of forward-forward dijets.
