Hi You may be having androgenetic alopecia or common male pattern baldness.since you ferritin levels are reasonable taking iron supplementstion is not going to help. I would advise you to take regular nutritious diet with proteins and micronutrients wit lots of fruit and vegetables. . You can use sodium laureth sulfate shampoo with conditioner for gentle cleansing andwashyour hair every other day. Donot use harsh treatments likehot combing and straigtening. You can also use Minoxidil 5% lotion lotion locally at bed time.i addition you can take tab Finasteride 1 mg daily . Continue the treatment for at least 12 weeks before you will notice improvement
