Re: thin/dry/damaged hair
I feel your pain. I also have thin, easily damaged hair, oily scalp, and dry ends. Worse yet, it's very fine textured - like baby fine, so when it's short, it flies all over the place at the slightest breeze. I hate using hair spray or a bunch of hair products so I prefer to keep it longer. The weight of longer hair helps keep it from being so "flyaway". If your hair has always been thin, then it's genetic and that won't change. If however, you suddenly started losing hair and it used to be thick, then you need to see a doctor.
The only tips I can give you are the ones that I've been using on my own hair that seem to be working. I've FINALLY gotten mine to grow out past my shoulders without it looking like fuzz. Granted, it took a looong time (several years).
If you can avoid washing it every day, great. If not, then shampoo ONLY the scalp area and crown. Lather it up like normal but don't wash your ends. If the shampoo gets on the ends (and it will), that's ok, just don't rub it in. Just rinse as usual then use a conditioner. Use plenty of conditioner on the ends, less on the top. I've started using an intense conditioner on the ends once a week and that's keeping it looking better too.
Next, get some Jajoba oil, or VO5, or a similar product. I use Jajoba because a bottle lasts literally for YEARS. It never goes bad. So anyway, you can do this with your hair dry or with it wet. Try it both ways and see which works best for you. Put just a tiny bit on the tips of your fingers and work it into the ends where your hair is dry. You may have to adjust how much you use. Start with less and add more if needed. Comb it through then let it dry. It will help make your ends look smoother while it's growing out.
As much as you hate to do it, trim your hair often. I never did cut off as much as a hairdresser would recommend but I do trim it more often. Be patient. Patience was the hardest part for me. Just keep babying your hair and giving it lots of moisture on the ends, frequent trims, give it a rest from blow drying and curling irons whenever you can and you'll be rewarded (eventually) with healthier looking and longer hair.
