It seems like my hair falls out noticeably more during the summer rainy season, but since I started using Riene Royal Jelly Shampoo on a friend's recommendation, I haven't experienced any stinging while shampooing. My scalp feels refreshing without irritation, and I definitely seem to be losing less hair. I recommend this to those with normal to dry hair; after drying, frizziness is reduced, while softness and smoothness have increased.
