Hello. Thanks for writing to us at healthcaremagic Seborrheic dermatitis is definitely a cause of increased hair shedding. There may another factors too responsible in your case, Post partum telogen effluvium (hair shedding) which usually begins 3 months after delivery can continue up to 6 months and may take another 6 months to recover from this hair loss. There might other contributing factors like androgenetic alopecia. These together might also be contributing to decreased volume of hair loss. I would suggest that you visit a specialist in your region. The doctor will assess the severity of your dandruff and judge whether other contributory factors like Telogen effluvium and Androgenetic alopecia, are involved or not. I would suggest you to use an OTC antidandruff shampoo e.g Nizoral, daily or every alternate days. For sever dandruff patients may also be started on topical steroid lotions for a short period of time. Topical steroids are usually rapidly effective in bring about remarkable improvement in the condition in 2 -3 weeks; the improvement can thereafter be maintained with antidandruff shampoos. Orally you may take a biotin supplement and an Iron supplement, once daily. These help in faster recover from hair loss specially if telogen effluvium is the responsible. Your doctor may also ask you to apply minoxidil if there is a component of androgentc alopecia. Regards
