The ladies like it, huh? ROFL. Well, I have a ten year old and he has had longish hair most of his life. We finally found a style we like, and while his hair is not curly (at least not now, but if he takes after me and his father, once he hits puberty - BAM! Megacurls!), it is very very thick and unruly. Luckily, I have similar textured hair, so I can help him out with the frizz and such. As far as those 'expensive' salon products, through a boatload of trial and error, I have found that there for every salon product, there is a product you can buy at your local walmart/drugstore that is equally as good but costs a LOT less. I have used the expensive stuff, and to be honest, with very few exceptions, it's not worth the money. Second agenda, How would he feel about just letting his hair 'do it's thing' and go curly? I know the curly look is making a big comeback right now, even with boys. That was what initially drew me to my husband...lol. I myself have very wavy/curly and frizzy hair, but I enjoy the curls now because I know how to manage them. I wish I had someone to help me when I was a preteen with styling issues, but my mom wasn't good with hair and always straightened hers and my dad went bald! I currently have my hair in mid-length layers and I love it (of course, I realize I am a girl, but still....). When I wake up in the morning, it does look kind of crazy, but with the right styling products, it lays down nicely and works well with the curls. The key is to not layer TOO much. I've noticed in the past with my hair that if the layers are cut too short or there is too much layering, it does end up looking kind of 'poofy' and unruly. With curly hair, if you want the curls to 'lay down' more, there has to be a bit of length...the weight of the hair is what causes the curls to not be so tight and kinky, and if there is no length, there is no weight to act against the curl - they just spring up and out all over the place!
If you like, I can recommend a few products that I love for the frizz issue or to help tame the curls. I like very light hold products that don't make your hair feel stiff or sticky, and I've found some good ones that keep your hair manageable and soft at the same time....I'm sure the 'ladies' would love that!
