Recurrent groin rashes that improve only briefly with Dermikem OC Plus are likely due to a fungal infection worsened by steroid-containing creams, which should be stopped, as they give temporary relief but cause recurrence. Instead, use a plain antifungal cream such as terbinafine, luliconazole, or ketoconazole regularly for 3-4 weeks and continue for 1-2 weeks after the rash clears, while keeping the area clean, dry, and using loose cotton clothing to prevent moisture buildup. Since the problem keeps coming back, you may also need oral antifungal medication prescribed by a dermatologist for a complete cure. For your scalp dryness with flakes and hair fall, this may be severe dandruff or seborrheic dermatitis; continue an antifungal shampoo, but use it correctly (leave it on the scalp for 5-10 minutes before washing) and consider adding a mild medicated lotion if prescribed. Avoid oiling excessively, harsh shampoos, and scratching. Because both issues are persistent, it is best to consult a dermatologist for a combined, long-term treatment plan.
