Aloe is a moisturizer... It will calm down the frizzies but it won't get rid of them. Neither will wax. The only way to get rid of frizzies is by either tying your roots, physically pulling them in with a crochet hook, or letting time to it's job.
Also because of it's moisturizing effect, pure aloe shouldn't be used on new locks.
If your using aloe on fresh locks, the best thing would be to add a little sea salt to it.
Also aloe will not "hold things together". This is the only advantage to dreadwax, but it could also potentially be it's pitfall if used improperly. If you use it properly, it will hold the hairs together during the first washes and prevent new dreads from unravelling which not only saves time, it also keeps things looking a little more proper for those of us who have jobs that demand us to look tidy. Now if used improperly, this continuous hold on your hair will prevent it from forming new knots which will keep your dreads from maturing properly.
What I've come to notice is that most people think they use wax properly, when they infact don't. All of the people I've talked to who have had problems with wax think they have been using it properly till I lay out the differences between what "properly" according to the jar is, and what "properly" according to common sense is.
Also most people refuse to admitt that their problems are caused by "their" mistake. Wax is a nice scape-goat. They often neglect to mention things like how they waxed daily, or decided to wax right out of the shower because they were in a hurry.
Also, I'm not trying to say that everyone should use wax. On the contrary, I'm just trying to let people know that there is a good and a bad side to wax and that their decisions will affect the outcome.
But if you choose the option to boycott wax, that's all good too.
Choose your own path, just be certain you know where each road can take you.
My itchies more or less went away after a month. It all depens on how long it takes for your scalp to adjust to the new routine.
Another thing that may help are scalp massages. Just rub your scalp from time to time (or better yet, get someone to do it for you). Feels great and gives your scalp that stimulation it used to get with brushing and daily washing.
