Why the hair is always tangled and shedding

To make the hair to last long, you should treat it as you own hair.

when the hair gets tangled, you need to deep conditioner it, all the hair problem is because the hair is dry, when you deep conditioner it and use the hot oil to smooth it, when you take care of the hair, pls don't brush or comb it, just use your finger to get it through, the hair will be better, because my own hair is always tangled, when I go to salon deep conditioner it, it will be smooth and beautiful
