Your description of the symptoms leads me to believe that your mother has a skin condition called eczema. Eczema is characterized by the appearance of red, itchy patches on the skin. It can be caused or aggravated by certain substances or environmental factors. To alleviate the symptoms, it is necessary to maintain the skin's hydration and avoid irritants. Using mild soaps and wearing comfortable, breathable clothes can also be helpful.

A keloid is when the skin grows too much after an injury has healed. They may feel itchy or painful. You could use silicone sheets or gel over the wound to stop it from growing back. Additionally, ask your physician about corticosteroid injections which can help flatten the keloid. 

You may have a common condition called a yeast infection. It is a common disease characterized by burning, a whitish or yellowish vaginal discharge, and also, redness around the vagina and itching. Vaginal yeast infections develop when new fungi appear on this secure bacterial turf. One drop of V wash liquid on the sanitary napkin and one drop on the private part will soothe your pain and prevent you from itching. When you temporarily mitigate the disease using V Wash and antibiotics, it does not mean it has been healed for good. Only by using an antifungal cream like Clotrimazole can you get fully cured. 

The contact dermatitis can last a long time. It depends upon the nature, frequency and duration of the exposure to the allergens. If the exposure to the allergens continues it might take very long time. If the exposure to the allergens is stopped then it will be recovered quickly.

You may be having a skin disorder known as vitiligo. Vitiligo is a condition in which parts of the skin turn white due to a lack of pigmentation. Problems like the skin shortage of pigmentation appear in white patches due to vitiligo disease. The methods of treating vitiligo can be quite difficult, but they can be handled with the help of some medicines like calming creams, phototherapy, and sometimes surgery. Not using sunscreen and the nervousness of a greater cause can intensify the symptoms. Visit a dermatologist for diagnosis and treatment.

As per your symptoms it would appear that you are suffering from acne vulgaris. This condition may also lead to pimples, acne and dryness on the face. This may also be associated with the dandruff and hair fall. I suggest that you consult a dermatologist who will offer the right diagnosis and treatment protocol.

It is hard to diagnose your balding without a professional examination. If you are worried about hair loss, you should visit a dermatologist who is a specialist in hairs loss problems. They can analyze your condition and give you optimal care.
