Suggest Treatment For Extreme Hair Loss

Hi i am 27 years old. I am working in Muscat as a Civil Engineer. I am having hair loss problem for last 4 years but i used to shave my head always for this problem. Now i want to grow hair but i am losing confidence while seeing the amount of hair that falls when i take head bath. I have consulted a doctor he just saw my head but did no diagnosis and said that it has passed on to me genetically. I dont know how he found that by seeing 5 mins He also prescribed me the following things: 1. Ketafung - for first five days 2. Bitozed Forte - for First 10 days 3. Harvest Capsules (Biotin, Collagen Peptides,Green Tea Extract, Grape Seed Extract,Amino Acids. Antioxidants, Vitamins and Mineral Capsules) - for 3 months 4. Minscalp F5% - (to be applied 1 ml morning and night for 3 months) 5.Renocia Shampoo for taking head bath So Can you please tell the treatment which i am undergoing is right? Also i want to say that my hair gets very oily after 2 days. but doctor has asked take head bath once in 3 days. Will all these things prevent my hair loss and will it stimulate new hair growth?
