For those looking into getting their first set of hair extensions, you might be wondering why you'd even bother going through the hassle of having real hair cut off and then putting artificial ones on. The answer is simple: to create the illusion of fullness at your roots. If you're new to the world of wearing hair extensions, you probably won't realize that you'll need to follow certain rules in order to make sure that your hair looks realistic. One of these rules is to ensure that your hair is clean before applying any form of weave. Dirty hair simply doesn't blend right. Another rule that applies to anyone who wants to wear fake hair is to always keep the hair length below the chin to avoid creating a "fake" fringe effect around your face. Another reason why 4c hair is so hard to grow is because of its thickness. Thick hair tends to weigh down the scalp, making it harder to distribute the nutrients evenly throughout the entire head of hair. To solve this problem, you can opt for a 4a hair type instead, since the latter has thinner strands. However, if you want to go one step further and experience fuller volume, you can choose to grow 4b hair, which has thicker strands.
