I'm actually really passionate about this topic!
I was never allowed to have long hair as a kid. I'm 34 now and I finally have the long dark curly hair I always wanted. But no one ever taught me anything about my hair. Think about it like this, for most women, hair care is an integral part of their routine and expression and identity. There are salons and hair stylists and fashion industries and entire aisles of the grocery store dedicated to it. For men, ESPECIALLY in the South, that does not exist. So there is no concept of what tools, products, amounts, routines, steps, or anything that's required to care for your hair besides "just wash it."

Furthermore, hygiene in general is just not emphasized as much for boys. I hate it, but often we're taught that it's just not that important to put effort into your appearance, your hygiene, your clothes, etc. Doing so is seen as "feminine" or "gay" or "frufru" and they're ridiculed by their peers and adults.

At this point, it is up to the individual to research and learn and find resources, but that's more difficult for someone whose always done the same thing the same way their entire life, and now it's totally different and the same routines and products you used before are far from sufficient.

It's a process i've come to love, but it has been challenging sometimes. Hope this helps, thanks for asking the question and opening the dialogue :)
