Dear doctor ,My son aged 24 is showing peculiar behaviour. 1}He is having curly hair on his head which he dislikes most. He wants it to be straight. So frequent he visit to Salon for hair straightening even fourrdays apart. By using excessive chemical his hair were broken and damaged. Then he started to make it straight by putting any oil whatever oil is found in the household. A full 250ltr bottle oil he pours on his head. And keep remain luke that. When he does not find oil he started putting water again and again at least 20 times at a stretch. He will go to bathroom put water one mug and comeback count and again he will go to bathroom for watering. After that he started sweeping floor and collect all. Dust rubbish put it on his head. On wet head it will stick. Then he starts combing again again .This continuous process will make his hair somewhat straight. We tried to convince him about the bad effect of floor dust but he starts requesting only once he will give. His face becomes so. Sad if we are strict. He starts. Begging us for putting dust on his head. I asked him why are you doing this? He answers this action will make him. Satisfied.Its. His strong desire he cannot control over. He feels tense if he can not do this. He feels in his inside always" something is kept pending .Some task is pending. So he can not even sleep. He has to put floor dust at least five times. Then he keeps hair combed and remain like this for hours till morning. After getting up from bed he will do it again at first then brushing teeth. It makes us worried. This is happening since six months. When we go for a tour this action is stooped in new place except putting water. i in winter night too .If we forbids or prevents him he argue" I am not disturbing you. Why will you prevent me. From doing my job? If he does not perform this watering and putting dust he feels tension and tell us" some thing is disturbing his mind pricking makes him. Crazy for doing this. Some task is. Unfulfilled" Apart from this he has special choice to select his bed. He always keep changing his bed place but never his pillow. He will stick to his particular pillow. Next he keeps all clothes of his mother under his pillow. On question he replies "my mothers hair is straight so if I am in touch with mothers clothes her gene will enter in to me to make my hair straight. He keeps 12combs with him and carry on combing. With each comb. And this comb he has arranged by stealing from his sisters room too.
