Hello and Welcome!
Vkb's post was completely on point. I just wanted to clarify, in case you didn't know (and I apologize if you already did) the distinction between moisturizing and sealing. A moisturizer is typically water-based, since water is truly the master moisturizer, and contains other emollients and ingredients that coat (and, at times) penetrate the hair shaft. An example of a moisturizer would be a leave-in conditioner like Alba Botanical's detangler or Kinky Curly Knot today, as well as Qhemet Biologics Burdock Root Cream. A sealer is a product that is not water-based and helps to retard the evaporation of the moisturizer from the hair. Sealers include plant butters (such as shea, illipe, cocoa, etc.). You would moisturize first and then seal. Again, my apologies if this is redundant.
Have you already assessed your hair type? If not, the method most conventionally used can be found at
http://www.naturallycurly.com/hair-types. I personally am a blend of 4A and 4B; I would even argue that I'm 4C in some parts (4A in the middle of my head, and 4B/C on the sides). The hair typing method is used to determine the extent of your curl pattern, that is, how loose it is vs. how tight the curl is. Once you've figured that out, I would also encourage you to check out threads that delineate coarse vs. fine hair. Briefly, you will know if your hair is coarse by looking at the individual strands and evaluating whether their diameter is comparable to a piece of thread, or if the strands are fine. I know that there are threads about this (I don't know where they are, but you can do a search to find them
). I personally have fine strands. In fact, the majority of Afro-textured hair is actually fine, not coarse.
You have beautiful hair.
I hope that this helps you. Feel free to send a personal message if you have any questions!
