I go weekly and I find that the benefits for me are that it makes my hair soft and it just blows in the wind. I have NEVER had a black stylist or anyone else have my hair that light and airy (Well I went to Egyptians a few times and they give the same results). The Dominicans don't use curling irons and a whole bunch of products which I think is good for your hair. They set it in rollers and then blow it out but some think the hot blowdryer is very damaging. But I think it is only damaging if you do it like every few days. I go once a week and have had no problems although I did start telling them to only blow my roots. Also an advantage is all you have to do then is wrap your hair every night and just comb it down in the morning so you never have to use heat. My hair lasts the whole week and I NEVER have to touch it with a curling iron. I threw mine in the trash. Also they are EXCELLENT when it comes to extending your relaxer. If you let them only blow your new growth you can extend your relaxer for a very long time. Also all of the dominican salons I have been to are full of black women with GORGEOUS long hair. All types too so they must be doing something right. Not to mention in NY they are cheap as hell at $15 for a wash and set. I say if you go once you will be instantly hooked. A lot of my out of town friends, when they visit me, that is the first place they want to go.
