Vitamins For Hair

For the last four weeks, I have tried several types of hair shampoo and conditioner, but I still can't find the "right" one for me. I have been experiencing hair fall problem lately; I think that it is because of the shampoo I was using and probably because of I had it curled recently (sad face).

My sister-in-law was telling me to buy vitamins for hair instead of trying all the hair shampoos and conditioners that I see in the shelves of our local supermarket (big grin). She said that the hair fall problem might be caused by the treatments I have had for my hair - first one, I had my hair dyed, now its brown; second, I had my hair curled; and lastly, I had a layered hair cut. My sister-in-law told me, layered hair cuts are prone to falling hair problem and drying hair problem (geez.. I didn't know that). She also told me that I just need to have the nutrients to my hair back. Problem is, I can't find this hair vitamins she used to purchase for my niece (sad face). I have searched all the drug stores in our area, but unfortunately, they have no stocks available. Now, I am thinking of seeking "professional" help for my hair problem; but still I need to consider my budget (big grin).
