Vitamins for Thicker hair

I want my hair to be ticker. I am already using shampoo for ticker hair, but I was wondering are there some vitamin supplements for ticker hair? I am 34 years old, male. Thank you in advance.

So many men and women want thicker hair yet there are only a few products that work to increase appearance of hair thickness. My hair dresser said that Re-thicken styling gel adds thickness to each hair while Hair Energizer vitamins and Silk protein conditioner feed the hair all that it needs to be its thickest. I would recommend you to try with the ultimate hair vitamin. It contains all the b-vitamins, mineral and amino acids that your hair needs. It grows hair faster and makes it healthier and is safe and natural without yeast.
