This was back when I was natural:
*Biggest screw up I have ever done, was allowing myself, for the very time to put box dye, into my hair. Not to mention I had no business using 40 vol. developer since I had no clue how. I was “transitioning”, but wasn’t sure if I was going to end up relaxing or just let my hair grow out. Needless to say I ended up with about an inch worth of hair all around my head.
*Second biggest screw up was thinking I could detangle my hair with a fine tooth comb. This was when I was seeing the likes of APL+ being natural, and for the longest I would steady just take an impossibly fine tooth comb through my hair. Wet or dry. But I have since learned from my former, tragic mistakes lol.
*A less major screw up that I still currently do from time to time is that I get hyper focused on my hair. Which causes me to fiddle and mess with it, leading to unnecessary breakage. Since certain parts of my hair are and have always been sensitive, those areas show damage a lot quicker than other parts that tend to hold up well. One time I went from box braids, to twists, to Dutch braids, co-washed a couple of times, to some fancy updo style all within the span of a few days. I just couldn’t keep my hands out of my own head. The amount of hair that had came out was unacceptable. And since then I have to train myself to leave my hair alone, and furthermore realize that it’s still just hair, and reminding myself that obsessing over my hair does nothing but damage my hair, and damage my expectations of my hair.
