1.) Biosilk Cure hair serum. Pricy but sooo worth it. Hated it when I was blowdrying, but my hair LOVES it when I rollerset.
2.) Via Natural semi-permanent hair color. Takes really well to my hair, easy to apply, and doesn't appear to be damaging at all.
3.) Not one, but two new moisturizers: First, ORS Hairepair Intense Moisture Creme, for those days when my hair needs a bit of an extra kick. It leaves my hair so soft, and shiny, and moisturized, it's unbelievable. Brought my hair back quickly after a major protein setback. If only it weren't so gosh-darned hard to find!!!
The second one, for my regular hair days, is the Palmer's Olive Oil moisturizer. Similar to the ORS one, but a LOT lighter, and has much "better" ingredients for the same price.
ETA: 4.) MN mixes! My hair growth rate has *really* picked up since I started using it. Another thing that's a bit pricey for me, and *so* embarrassing to buy (imagine walking to the checkout counter with multiple boxes of the stuff), but again, a great investment that I've made this year for my hair.
