Feel skin very sensitive and feel itchy on scalp after treatment. Any suggestions?

Hi I'm 24 and I started Venus Viva treatment 7 months ago. After the 4th treatment, I feel my skin over sensitive, like always get redness on the central area of forehead, nose, chin and cheek, especially after washing my face. I also feel itchy on scalp so I need to wash my hair more frequently. My doctor advised me to apply hydro-cortisone cream but it did not work very well. What should I do for this situation? Should I stop the treatment? Thanks Rainie
