Hair loss problem?!!!?

Hey, I'm 19, male... I dyed my hair about 3 months ago. One of my lady friends dyed my hair dark brown for me, i think it was the permanent dye I don't remember. but neither of us really liked the way it looked so I believe it was either the next day or 2 days later we did it again, this time i'm positive it was permanent jet black hair dye. I think loreal. anyways everything was fine for a week maybe, then my hair started to fall out! 3 or 4 hairs on my pillow in the morning, 2 or 3 on my hands when i'd shampoo my hair in the shower for a period of 3 months?! 3 months! and my hair has thinned consideribly, i used to have thick awesome hair and now i'm scared it's not going to grow back as thick if at all! it just keeps getting thinner and thinner on one side!? what do i do?! are there vitamins i can take? do i need to see a dermatologist???????? any comments/advice would be helpful, thx.Hair loss problem?!!!?
Now you see the effects of hair dye. That happens when your hair has been given too much chemicals! Remember, its not just a coloring element, it has something that makes the color cling to your hair and scalp. What you need to do is grow new hairs! and don't dye it all the time or never!
