Hiya!
I don't really mix my own products either, as I LOVE to buy cosmetics! I do have a conditioner spritz I made myself which contains 1 part conditioner, 1 part sweet almond oil, a few drops of lavender oil and the rest is filtered (or bottled, or destilled) water. It's an 8 oz spray bottle. I use this at night time to braid my hair and in the morning to refresh my hair. Now that my hair is a bit longer I braid at night time to prevent the tangling and cut down the knots. I still get them, but not as bad as before. Make sure you cover your hair with a satin scarf at night or sleep on a satin pillow, but you probably know that already.
I wash twice a week now, but when my hair was shorter I washed nearly everyday (though these were co-washes). As mentioned, I also did conditioner washing, so maybe this is something you may want to look into if your hair is really dry.
I use Aveda Brilliant shampoo at the moment (as you can see in my siggi). I'm not specific on my conditioners, as I buy them by the truckload! However, Aussie Moist is a great conditioner!!
I also recently bought Qhemet Sidr Tree Balm (which is the lighter version of the heavy cream). I really like it, because it keeps my hair soft, and I don't need to use a lot, so it will last me for ages. You might want to try that too.
I don't have much of a routine other than washing twice a week and braiding my hair every night. Then again, maybe that IS my routine. Make sure you keep your hair moisturised. I read that you are transitioning? If you can (or want to) make sure you keep your ends trimed regularly to prevent excessive breakage because of your two textures.
Um, don't be like me and buy everything you read about...... Oh, what the hell -- knock yourself out!!!!! tee hee
Hope this helps! Good luck!
