We investigate the spin relaxation and Kondo effect caused by magnetic impurities in doped transition metal dichalcogenides monolayers. We show that the transport lifetime and spin relaxation are much longer when the Fermi level is inside the spin-split region owing to the spin-orbit interaction in the valence band. However, the Kondo temperature variation with the Fermi energy and the position of the impurity level in the valence band are almost the same for both electron and hole doped cases. The strong spin-flip events accompanied by changing the valley index take place in the spin-split region leading to the Kondo screening of the impurities.
