So far so good

### ⭐⭐⭐⭐⭐ Beautiful fragrance and nourished scalp
*by R***Y on 12 April 2025*

I tried this at a salon when I had a scalp massage. Then I bought it from Amazon. It makes my hair smell divine, nourishes my scalp and also creates volume. I use straight after the shower but before blow drying. I have definitely noticed a soothed and comb scalp following using this.
