  We show that description of the quark and gluon helicities in the
Double-Logarithmic Approximation (DLA) solves the proton spin puzzle. First we
explain how to solve this problem in the straightforward way by combining the
RHIC data and expressions for the helicities calculated in DLA. These
expressions are complicated to use, so we approximate the helicities by simpler
DL expressions and obtain a tentative solution to the puzzle.
