A necessity? No but truly a luxury.
I could live without this, I don't feel like it's a necessity but it's like taking a bath sometimes it's just about comfort. This is a good way to treat yourself and care for your scalp health. I use it right before I shave and I notice it makes my scalp feel good. This is better than shampoo: I think it helps scrub your scalp and it is good to use right before shaving because it makes your scalp nice and smooth ready for an easy shave. Is is necessary? You could live without it but it is a luxury to have. It's worth trying at least once!
