Hi Rw3! Aw, that must be hard!
Maybe you could try a coconut oil moisturizing treatment. I have heard that coconut oil works wonders for dry and damaged hair, although I myself use an Olive/jojoba oil mixture since coconut oil is more expensive for me. Most types of oils really make hair healthy and soft, so whatever type you could afford would be good. I usually do an oil treatment to my hair before I take a bath or shower (I just rub the oil throughout my hair and scalp and especially at the ends of the hair and let it sit for 30 min. or longer). I will even rub just a small dab of oil into my ends whenever it is hard to manage or feeling dry without washing it out.
There are some cons to using oils though. Using them too frequently can weigh down curls, so just be careful not to do it too often if you do try it.
Be careful also with shampoos and conditioners since most shampoos have sulfates which are harsh on the hair and most conditioners have cones which can build up on hair after a while and cause dryness and breakage. Also be careful not to use a hair brush on your hair, especially when it is curly since this will cause breakage. The best thing to do is use a wide tooth comb and detangle gently (some people use a tangle teaser which I have heard is also good). You might know about all of this already, but I just thought I'd say it just in case.
I hope that this helps and I also hope that you have a nice day!
