Kiehl's Since 1851 Smoothing Oil-Infused Leave-in Concentrate

This Smoothing Oil-Infused Leave-in Concentrate is a lifesaver for dry, frizzy hair. It adds instant softness and shine without feeling heavy or greasy. A little goes a long way, and the scent is subtle but luxurious. Perfect for daily use — my hair looks healthier, smoother, and more manageable every time.

Effective in smoothing thick, frizzy and dry hair. Used in when hair is 70% blow-dry and is using the third bottle now. Good for Singapore weather. Only concern is price on the expensive side.

i like how it keeps my hair smooth and silky unlike other oil based hair oil this is not sticky

My first time trying such an expensive serum and i never regret! They tame frizz after consistent application. Now i have nice soft silk hair

Most of us are take really good care of our skin but not our hair. It’s the most neglected part of our body. Our Hair actually needs the same amount of concern and attention like our skin and hydration is key to all issues such as split ends, damaged hair, frizzy hair etc. It has been a week since I am using the serum and I am hooked. It provides a coating on my hair that protects against Heat and UV. It actually turns my frizzy hair strands into silky like ones, keeping my hair smooth and soft. Though it’s a coating, it’s feather light and I can easily comb through my hair with my bare fingers, tangle free.
