Hi.. Well, Alopecia that is common in men is Androgenic Alopecia and it is commonly caused due to sensitivity of hair follicles to androgenic hormones.. At times it can be genetic in nature.. It is most common on men and leads to loss of hair in large patches.. If the scalp is irritated then it has to be stopped and you should consult a Trichologist and get evaluated and he can advise you investigations like hormonal assy, blood tests, trichogram, dermoscopy to rule out the exact cause of the problem and treat you accordingly.. ]You can be advised to take Biotin and multivitamin supplements.. You can also be advised to take Finesteride orally if there is androgenic aloepesia as it suppresses androgens.. You should massage the scalp with warm coconut oil.. You should take a nutritious diet and drink plenty of water.. You can also discuss about platelet rich plasma and Mesotherapy.. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Honey Arora, Dentist
