<s>[INST] respected Sir, I am a male, aged 33 years, I have been suffering palmar and planter psoriasis since last 10 years, and I am using topical steroids, recently I have developed alopecia areata very rapidly and diffusely in my scalp here and there, which I have prescribed topical steroid lotion. But it did not help me, then my doctor was prescribed Tricort 40 injection . I am very anxious about my condition, please suggest [/INST] Hi...thanks for writing here. Let us discuss your conditions one by one. Alopecia errata is autoimmune condition where there is a sudden loss of hair in an area in scalp.Most of the times it is self limiting recovering in about 6 months, but when it is spreading it is little worry. If only 2 to 3 patches are there then you can take injection tricorn 10 mg in the lesion itself, it produces good results and if multiple patches are there then systemic steroids are prescribed either in.tricorn or oral mini pulse therapy. You can discuss these things with your dermatologist. You may continue with steroid lotion along with minoxidil 5% and tacrolimus ointment. Palmoplantar psoriasis is recalcitrant condition, Since you have disease since 10 years you can go for calcitriol ointment, also methotrexate therapy can help you. Always use a mild soap, apply a lot of emollient like Venusian cream along with steroids, always cover areas with thin plastic bags after applying creams, since it increases penetration of Chat Doctor.  </s>
