OP, I feel like I'm suffering from the same thing. And, seeing your post has made me realize that I may just have to deal with it. I have to agree with the other ladies though. There's nothing you can do to actually make your hair thicker. All you can do is use products that give the appearance of thicker hair. However, if you've been using anything like oils, grease, butters, or anything of that nature, be advised that the more you use those things, they more they weigh the hair down and make the hair appear thin. I suffered from that a long time ago when I used to use the forbidden Pink Oil Moisturizer religiously. Since turning away from that, I'm thinking now that the reason my hair appears to be thin is from flat ironing too straight or breakage from stretching my relaxer. I am relaxed, but haven't had one since Sept. 09. Based on what I've read here, I've narrowed my causes down to 3 things. So, if you don't get the responses you're looking for, my suggestion is to do some more research here and other places on the web. That's what I've been doing. If you're really concerned, maybe you should ask your stylist or even consult with a dermatologist. Maybe they can help you determine if you just have naturally thin hair. I don't know much about these things, but just decided to try and help you if I could.
