Hello and welcome to HCM,
The most common causes of hair fall
are fungal infection
of scalp (dandruff), poor nutrition and autoimmune disorders
For prevention of hair fall, dandruff needs to be managed.
Diet rich in proteins will be helpful.
Scalp massage will increase the blood circulation and strengthen the hair roots.
If you have observed that hair fall decreases with intake of vitamin tablets and folic acid
supplements, then you can take the supplements.
You can take vitamin B, C and E since they are water soluble, however, intake of vitamin A
and D should not be taken without consulting your doctor.
Folic acid should also be taken under supervision of your doctor.
Thanks and take care
Dr Shailja Puri
