This is the exact problem with the Dominicans salons. If you are a Latina or if you have strong hair, your hair will grow long AND THICK. Thick is the operative word here ladies, because it is possible for hair to grow in a broken fashion and that is why we are always being asked to get trims.
I am not Latina, I am not mixed, I am not 2a/2b/3a/3b/3c, I am 4K to the nth degree, LOL!, with hair that is naturally fine (my Dominican salon owner calls it soft) and fragile to begin with. I went to several Dominican Salon and one of them helped my hair to grow to its current length. But I came to this board because my hair was thin and breaking even though it was past my shoulders, from the weekly rollersets. Telling them not to blow it out or to only blow the roots only helped the problem minimally. Their rollerset methods can damage your hair!
I really recommend airdrying and not manipulating as opposed to even rollersetting. The Dominicans are rough and they rollerset with babyfine tooth combs. I even gave one of them my hairsense bone comb to use and she was still trying to hide all the hair that she took off my head. After she rollerset my hair, she sneakily tried to quickly take out all the hair that was in my comb after the rollerset before I could see it. Dang girl, if I brought my own comb, you shoulda known that I didnt want you to take out a lot of my hair! I firmly believe that it was this type of combing that led to my hair breaking and I have gone to some of the most renowned (if you can say that about a Dominican salon) Dominican salons in NYC, including Mirror Image.
If they ask after they've done your hair if you need a trim say no -- they've probably already given you a free haircut!
Let's be honest here: I think that many people like the Dominicans because they will get your hair so straight and so swingy and bouncy. I have found few black salons that use their technique and when they do they are expensive. However, I feel that the Dominicans were part of my progression to hair health. My hair has grown from chin length when I was in grade school to past my shoulders now. However, it is thinner than it should be because of breakage. I want to have hair that is brastrap AND not broken, and that is why I came to these boards. I am happy that some people on the boards are able to have long hair when they blowdry or flatiron their hair every week (it makes me wonder what they were doing before they came to the boards, but it's all good) or get Dominican blowouts every week. I am not one of these people and this board has helped me to understand that. Thanks for reading and have a good day.
