Oil build up
For my wash day I do a hot oil treatment before I do the rest of everything else and I've noticed my conditioner and non sulfate shampoo don't work as awesome as they used to back when I didn't do hot oil treatments. Could I be getting build up from using to hot oil treatment every week. If so then how often should I do hot oil treatments on my hair.
when I was in the early stages of my hair journey I had the same issue from doing the same thing. I cut my hot oil treatments down to an as needed basis when my hair needed a boost of moisture usually about once a month. To eliminate that build up I used a clarifying shampoo.
