About A Month In And Looking For Advice

So I stopped combing my hair and using chemical shampoos about a month ago, and for the most part my hair still looks very similar. I've only washed it three times (about once a week, longer if I can stand it) using only baking soda and ACV. If I look closely, I can tell that my hair is starting to separate and very barely form locks, but I was wondering if there was something I was not doing. I'm not exactly sure how to go about separating/ripping it or whether it is even necessary yet. I've always had extremely straight hair, on the longish side, and right now it's about mid-shoulder length. I was also wondering what can be done about dandruff because, besides the bangs getting a litter greasy from me pushing them behind my ears all the time, my hair looks pretty clean and dandruff has been my only problem.
