Prenatal Vitamins and hair growth.

Does prenatal Vitamins actually grow your hair out even if your not pregnant? I've been struggling with hair growth for the past 5 months and nothing has worked. I don't use heat on my hair what so ever. I shampoo my hair every other day. And last time I died my hair was in January. I used to take Hair Skin and Nails by ItWorks, and it worked. But it got where I forgot to take it everyday and it just messed me all up. Right now my hair is a little past my shoulders and I hate hate hate it. But I'm trying to not cut it because everytime I cut it I regret it. I'm trying to get it to all one length and keep it growing. I use deep conditioners every now and then and I even massage my scalp. I've literally tried everything. And I heard prenatal Vitamins actually grow hair...also anymore tips would help. And different hair products. My hair is frizzy, dry and thick. So anything will help! 🙂🙂🙂
