I have used several hair treatments; many of them leave my hair greasy and tangled. Thankfully, Amika Hair treatment is not one of them. The lightweight oil leaves my tresses softer, smoother and sleeker all after one application. To use, simply evenly distribute a couple drops of the oil through wet hair or dry hair. Apply before blow-drying to add a bit of sheen and no one can tell the difference between a professional blowout or one that you woke up 2 hours earlier to do.
