My daughter is 13 year old. She has started grey  hairs at a very young age,and the number of grey hair seems to be increasing . We want to possible reasons for this. Should we get any blood test done,such as for iron,vitamin B12, Vitamin D or thyroid? Is onion juice safe to apply on her scalp,and will it help? Please suggest the right treatment and precautions.

I could see a mole on my head and it pains whenever I touch. There is a catch, if I wash my head it won't pain at all. Sometimes it doesn't even pain for days. This pains only when I touch it. Is it something serious? Or what it is?

A trichologist prescribed DUMAN /dutasteride to control hairfall also told that may need to take long term. Along with this Minoxidil 10% is also given. My question is if long term how long would the patient need to take this medicine “DUMAN”? Are there any side effects? A known lady friend told me that she took it when prescribed by a doctor and once she stopped it her all effects were reversed. Kindly clarify if there are side effects. Also when the medication will be stopped will it give any reverse effects. The patient doesn't have any medical issue, is absolutely fit doesn't consume any junk food.All Blood reports are normal too. Only iron is low for which she is taking tab as prescribed. Thank you in advance

I am writing to schedule a consultation regarding a persistent hair loss issue. For quite some time now, I have been experiencing significant hair fall, and I have noticed that my hairline has receded considerably. The thinning is becoming quite noticeable, and I am concerned about further hair loss. I would like to get a proper diagnosis to understand the root cause (whether it is genetic, nutritional, or stress-related) and start an effective treatment plan. Please let me know your availability for an appointment. I will bring along any recent blood test reports if required. Thank you for your time and guidance. Best regards, Mukesh kumar

I am using Dermadew acne soap, and lacto calamine hydrating gel moisturizer, and fixderma shadow sunscreen, but still I am getting comodones. What to do?

Prescribed azelaic acid 10% for 18 days (acne marks), but continued using it daily for 53 days by mistake. Had escalating breakouts (tiny comedones, whiteheads, pustules) since week 1 of using it, worse each cycle, mainly on jawline/lower cheek. No burning/stinging ever. History of mild hormonal comedonal acne since age 9, never cystic. Stopped azelaic acid now. Should she completely discontinue it, or can it be reintroduced later at lower frequency? What likely caused this reaction?
