Welcome to the CURLS Forum!!
People of color have hair that is naturally very dry. And, this is why, African-American, African, and Biracial individuals must infuse their hair with more moisture on a daily basis than say someone that is Caucasian instead.
There are no products out there that can totally eliminate natural, inherited dryness to the hair. However, a product line like CURLS can definitely help to provide temporary moisturization and get the hair to retain more moisture to it long-term as well. Now, I see that you got one of the sample kits. And, I want you to know that for your hair to gain noticeable temporay as well long-term moisturization benefits, your hair would need more than the small 2 ounces of product that are in the sample kits.
Anyone that has long, quite thick, or dense hair would go through 2 ounces of product in a very short time. Now, I don't have a picture of your hair to see how long, thick, or dense it is. And, without a picture I can't accurately review your hair for a hairtyping either. As, it has only been a few months since your last relaxer, and even though you do have newgrowth, you still have a lot of relaxed hair that is still on your head.
Two ounces of products goes up very quickly. Therefore, if you have hair that is quite long, noticeably thick, dense, or severely dry then your hair would certainly need more product for it to be maintained for even a few days than what 2 ounces could provide. And, you definitely would need to be able to have product that you could continuously use from. As, after you run out of product, then you don't have any more product left to put in your hair and that can be a problem. Also, being paired up with the right products for your hair is very important as well.
With any product, your hair has to form a union with the products being used on it for you to most clearly get the best results that you can from it. Hair doesn't form a perfect union with a new product in 1 day, a few days, or even a week. Because everyone's hair's needs are different, it can take anywhere between 1-3 months before you start seeing prominent results to your begin to come into play. But, as weeks go you can start to expect gradual results that will start accumulating into more long-term bigger results. But, you have to consistently use the right products for your hair and stay committed to the new regimen as well.
