The first time I really tried a hairdo to relax was more like a self-booster. I worried about getting my hair colored. After I finally made an appointment and let the professional put the color on, I was so happy of the result, that it boosted my self-esteem. I'm a level 9 blonde for natural color and I'mm now down to a level 5 light/medium brown color, because I love the more dark hair colors. So I guess doing this is pampering yourself.
Tip for students: set an appointment with your barber right after the last exam. It's always a very good treat for finishing the exams with. It doesn't have to be something special, a good wash with a little massage can do the trick. It doesn't have to be coloring/perming/brushing/cutting, just tell that you have finished the last exam and if the barber takes real care of you and your hair, your bound to get a nice wash and massage!
I prefer to take baths to pamper myself. I do love face masks but done myself I don't really like it so I have facials for that. For my baths I love anything that makes bubbles but sometimes I will go for something that do not make bubbles. Sometimes I put on music while taking baths, sometimes I use a machine with nature sounds and sometimes just silence.
