Brief Answer:
Hello, welcome to ask a doctor services.

Detailed Answer:
Hello,
You are suffering from red acne all over your head. You are also having extreme hair loss and hair thinning.

You also have itchy head and it hurts when you comb. It is making you feel uncomfortable. I can understand your concern.

You are suggested to take bath regularly. Cut your hair short so that it is manageable.

Clogged pores often cause scalp acne. Keeping the hair and scalp clean and using medicated shampoos like Selsun or antidandruff shampoos can help treat the condition.

Sometimes, itchy scalp can occur due to fungal infection, mites infection, etc. To get relieve from itchy scalp you can take antihistamine at bed time. You can take antibiotics (doxycycline) to get rid of scalp acne. Applying a thin layer of ointment hydrocortisone on the area affected effectively stops itching.

Get clinically examined by a Dermatologist, if fungal infection is detected, it will be treated with oral antifungals. Applying antifungal ointment on the area affected is helpful.

You are suggested to use shampoo containing the ingredients, ketoconazole, salicylic acid, glycolic acid, benzoyl peroxide, etc.

To prevent scalp acne and hair fall, take diet that boosts skin health, avoid taking oily, spicy, junk food.

You should wash your hair soon after exercise and as soon as you return back home to wash away dirt and pollutants that may trigger your symptoms.

Avoid using hair sprays and gels, switch to natural hypoallergic hair care products.

Wear a loose fitting hair gear, let the scalp breath so that sebum does not accumulate causing clogging of pores.

Hope I have answered your question. Take care.
