Remember this stuff??? Well despite that fact that 98% of Black women and girls have used hair grease, either because of tradition, Your mother used it, your grandmother most definitely used it, and perhaps you even still use it on your hair and scalp. However, there are some cons to using it!
Hair grease contains petroleum. Which is not what you call a “moisturizer”, it is a barrier which means that having no moisturizing properties of its own it reinforces and seals the moisture into skin provided by other sources. For instance, if after applying water to your skin, you coat it with a layer of petroleum, you will have effectively sealed in some of the moisture “from the water” into your skin.
I do not recommend people using hair grease, especially women, because they have hanging hair. Men/boys is a different story. If you put Vaseline on your scalp, what would you think about it? It is too thick and will do nothing but clog your pores and completely removes the ability for your scalp to breathe freely.
