What is the difference between leave-in conditioner and hair serum?. .Are we supposed to use both?:):confused:

Leave in Conditioner is just that. It's a conditioner that's left in your hair. A hair serum is generally clear and a little on the greasy side. But that's meant more for shine, frizziness and to add softness. Conditioner is usually for repair/preventative. You can use both but you don't have to. You should always use a conditioner, though. At least every other shampoo.

Is using serum better than using conditioner? My hairs break a lot what should i use ?
