Review title is Good for Calming Frizzy Hair [SEP] This argan oil and shea butter serum works pretty well. I use it on really dry days. When it is dry and cold my hair is crazy. It sticks out every which way and is impossible to make it lay flat or be reasonable. This stuff helps calm it down. It makes it actually lay down and gives it a smooth look. It does take some practice at applying it. If I get distracted it is easy to put too much and make my hair look oily. I have used product like this in the past that come in spray bottles or pump bottles and that made it easier to get just what I needed. This bottle has an eye dropper type applicator. I am not a fan of this. I use it to drop some into the palm of my hand and then rub it between my hands and carefully apply it to my hair starting in the back on the most underneath layer that way the front and the top layer do not get too oily. After applying it I gently brush my hair to work it through completely. I regularly put way too much in my hands and wash it off so I don't over do it.<br /><br />I received this product in exchange for my honest and unbiased review.
