Is it okay to condition with silicon-free conditioner once in a blue moon? I've been no-poo for three to four, since mid-December. Every week I wash with baking soda and apple cider vinegar. I was wondering if it would be fine to wash with conditioner once in awhile? I kinda miss the feeling and smell of it. I am worried it'll re-grease/oil my hair, as everything's been looking so clean and not greasy for such a long time. What's this I hear about silicone-free conditioners?
