If I shampoo my hair, yes because shampoo strips the oil from the hair and can cause it to become dry and brittle. If I don't shampoo my hair, no because I don't need to.
I use two-in-one shampoo. Just conditioner by itself weighs my hair down and makes it oily. If I'm gonna wash my hair, I don't want it to look dirtier than it did before.
*something is needed to release the tangles after shampooing the hair)
Love the way it smells
