Can I ask a question about black / natural hair?

[dr.girlfriend]

Hi guys.  Not sure if anyone is around, and this is a little awkward, but I was hoping I could ask a hair question.  My husband is no help since he's always kept his hair shaved very short. 

I'm of Indian descent, and my husband is black.  Our son's hair started out more like mine -- thick and a little coarse with a loose curl -- but as he's gotten older the curl has gotten tighter, and he's also wanting to wear it longer. 

Right now it has some nice curls in the back, but the front and top is more frizzy.  Can anyone recommend some products and techniques to help define the curls?  I've been trying the kind of shea butter leave-in conditioner and styling milk products I use on my own hair but they don't seem to work that well.  Something I could get at CVS/Rite Aid or someplace like that or online would be preferable.  I tried looking for hair places that specialize in black/natural hair on Yelp in my area and couldn't find anything.  I feel bad that I'm pushing DS to get his hair cut just because I don't know how to deal with it.

This isn't the best picture but should give you a sense what I'm working with.  I guess you can't really see from the picture, but it's like it curls at the ends but is more matted/frizzy at the roots.  My hair tends to get oily but his seems super dry no matter what.  We wash it about once a week, run a wide-toothed comb through it, and put in the styling milk and let it air dry.  Sorry for the creepy retouching.

I have a tighter curl but my hair will frizz/tangle at the root and mid-shaft then have curls at the end so it may be somewhat similar. I like shea mostuire coconut & hibiscus line. I also loved Cantu products, which are much cheaper than the SM. You should look up the LOC method. It stands for Liquid Oil Cream. This method helps retain moisture in natural hair. Youtube is full of videos about the method and product recommendations.
