I have thin, delicate hair that gets color-treated with high- and low-lights every 6 to 12 weeks (as if you couldn't tell;). It’s fly-away, prone to split ends, and, if I don’t watch the heat settings, it can get to feeling like straw between salon treatments. Luckily, my daughter (“Product, product, product, Mom!”) introduced me to Redken Smooth Down Heat Glide. I use ½ pump after washing and mousing, smoothing it through my hair from mid-length to the tips. No matter what hurried-up high-heat stretching exercises I put my hair through in the morning; it now looks smooth and just-from-the-salon sleek. My daughter’s hair is thicker and longer, so she uses two to three pumps per use. You can also smooth a little extra on after drying and styling, especially on those especially wet and humid days when frizz is a real problem. And it smells great! I found prices ranging from $14.00 to $17.00 dollars, but at a few pumps a use or less, it will last a long, long time.
