You may not already know it, but your girlfriend has some pretty specific opinions about hair, including yours. She also probably has the expertise and the tools to give you a complete and mind-blowing hair makeover. So if she offers, you should see it as a bonding experience and let her. Or you could just listen to her when she tells you not to shampoo your hair so much.

Why not? Doesn't she want you to be clean? Good point, but here's the deal: Shampooing your hair every day strips it of its natural oils. This leaves it frizzy and dried out. But quitting shampoo cold turkey really sucks. If your hair is used to being washed squeaky-clean every day, it's also used to over-producing oil as compensation. The finer and longer your hair, the more oily it will appear between washes. Leaving you with greasy roots and dried-out ends. Not your strongest look and not something anyone wants to touch.

So, shouldn't you just bite the bullet and endure a few days or weeks of greasy hair? If that's the only choice, yeah. But it turns out you don't have to go cold turkey. Cleansing conditioner can wean you off shampoo and actually make your hair look and smell better. Without any harsh detergents, it simply removes dirt and adds moisture. Thing is, it's probably not sold at the bodega down the street from your apartment. It might, however, be sitting in your girlfriend's bathroom right now. Maybe you should ask her. Here are some we really like.
