Dye my dreadlock six year ago didn't use condition on my hair dye stayed on my hair now hair loss with bulb i cut it, went dermatologist, still fall out?

Many possibilities.: Hair "turns over" faster than just about anything else in the body, and many things - from illness to injury to surgical procedures to hormonal imbalances to infections to stress - can interfere with the normal hair cycle. Don't waste your money on tonics and "hair vitamins". Let a dermatologist go through the possibilities and find the cause. (hair loss with the bulb attached is common.).
