I wish I would have known that you should squeeze out all water from your hair before drying, that leave-in conditioner is much better than heavy creams for me, that I need a buttload of conditioner to detangle properly, that gel is pretty awesome when you scrunch it out, co-washing is not that great for me / I need low-poos + clarifying shampoos regularly, protein is my best friend, and that blow dryers + diffuser can be used without getting heat damaged with proper use. I also wish I never had my hair relaxed and I wish I didn't try ironing it so much. My hair looks super dead in some of my school pictures before I chopped it off. I also once ruined my hair when I used an iron on WET hair. Omg the damage 💔
