It takes a while to dry hair but the main problem is women pick a beauty shop they like and they go there no matter if they moved out of the hood. Also beauty parlors are ratchet as hell they routinely triple book their clients and women roll with it. If a chick insists on getting her hair done on a saturday you're not gonna see her at all that day.
But the real problem is laziness, Black women say that maintenance of natural hair is way more time consuming, You have to properly oil and condition it wrap your hair up at night. Easier and cheaper to just cornrow that shyt and get a quick weave.
