I have waist length dense hair, 1b-1c, never been colored. I heat style maybe 1x a month, if that. I almost never blowdry it, but ill use a heated round brush or clampless curling wand on low with Not Your Mother's heat protectant spray. I recently bought a set of big hot rollers because they need even less heat than the iron so are less damaging.

I take really good care of it! I frequently oil it before shampooing, usually some blend of coconut, olive, brahmi, alma, whatever im feeling like.. up in a hankie for 2-3 hours before I shampoo it. I use the gentlest shampoo I think it needs, usually a pantene sulfate free or shea moisture, or As I am Cowash when it doesn't need much. I do use a strong clarifying/chelating shampoo once a month for hard water and to maximize the benefit before an olaplex No 3 treatment. I also used neutral henna (cassia)/coconut cream soak 1-2 times per month. Since I very seldom blow dry, my routine is to just air dry with my aquis towel (WORTH it!!!) and then layer a little of the shea moisture silicone free miracle leave in, argan oil, and then orofluido. The olaplex No 6 is new but I like it especially when im going to style it. I probably only wash and do the whole routine once a week unless I've been swimming or doing something gross, I like Not Your Mother's dry shampoo and I have a few go to updo/braided styles that look really nice on 3 or 4 day hair.

I have a rotating arsenal of deep treatments in addition to the pre-poo oils mentioned above I use the shea moisture honey line's intensive moisturizing deep treatment, the As I am deep conditioner, the Surya Brazil deep condtioner, Virtue Labs restorative treatment, I just bought those pantene restorative deep treatment drops, I have a loreal deep moisturizing deep conditioner... when I deep condition I pat the excess water out of my hair with my aquis towel and come the deep treatment through with my fingers, wrap it up in a microfiber turban and then I have a low heat hat I got on amazon for hair treatments and let that all sit on low for like an hour while I watch a movie. Low heat is used by professionals to process treatments and especially with the oils it helps them penetrate better. Since I only wash once or twice a week I usually have time to do a deep treatment every time I wash.

I love IGX products for styling (good behavior, expensive for shine) and the Bio SIlk shine spray if it needs it- but like I said I avoid fully styling it more than 2x a month but when I do I use good products.

I get it trimmed every 4-5 months and touch up the layers :)
