It's fragrance-free, gentle on the skin, yet smooth! Perfect for morning sickness! I started using this shampoo after my head got a rash when I was using another shampoo. I used a different shampoo for a while after that, but then I got pregnant and started having morning sickness. I can't stand scented shampoos, and I feel nauseous every day while bathing, so I asked my husband to buy me this. As a result, since it's fragrance-free, it didn't make me feel nauseous, and it was really good! I recommend the treatment, as it leaves my hair feeling smooth, rivaling even the best shampoos. There's less treatment than shampoo, so be careful when using them together.
