at your line looking like the stock exchange.
I cut my own hair and do my own edge-ups. It's pretty good considering what I have to work with. Sometimes when I'm really on point I'll be on some Jamie Foxx type ish. I recommend you learn how to do it yourself. That way you can do your own touch ups so you're not looking all raggedy. Just be careful to not push your tape-line too far back. Unless you WANT to look like Kane.
If you want to see how you should brush your hair, especially in the back, peep my Amish picture earlier in the thread. You can see which way the waves spiral. Before you do that on yourself, get two mirrors and look at the back of your head, peep where your spiral starts and work from there. It's easy once you get the hang of it, fam. Just beware, if you fuck up and start to spiral off too early you can get yourself a MAF-part on the back of your head... looking like a sheep's ass and shit.
Lastly, no, I don't spend that much time on my hair. When I'm waving I usually incorporate haircare into my daily routine. It's like brushing your teeth, or taking a shower. Would you skip either? But beware, just like you can't clean your teeth with just water and a tooth brush, you can't get waves with just a du-rag and pomade. You godda put in some work. And don't be cheating with those kits. Burn the shit outta your scalp that way. Get the fuck outta here with that bullshit.
