The best thing a man can do on a first date is be a friend. I think that's the biggest mistake men make on the first date. Just get to know me. Be my friend. Just kick it with me as if I was hanging with a homeboy. It shouldn't be this awkward situation. It should be that we're there, having a great time.
When my hair is curly, I use Suave coconut conditioner. It's not a leave-in, but I use it like one. It is so light and really brings out my hair's curl. A lot of leave-ins are too heavy, but this one is just perfect. When it's straight, I love Frederick Fekkai Tech Shampoo & Conditioner and their Olive Oil glossing cream.
