Kristin Ess Weightless Shine Working Serum

The Kristin Ess Working Serum is that girl. Super lightweight, non-greasy, and gives my hair the perfect amount of shine and smoothness without making it feel heavy. I use it on damp or dry hair and it tames flyaways instantly. Plus, the scent is subtle but so good.

I've been using the Kristin Ess serum on my damp hair, and I've really noticed a big difference—it controls frizz, leaves my hair softer, more manageable, and with a natural shine, without feeling greasy or heavy. It has a lightweight texture that applies easily, a clean and pleasant scent, and comes in a practical bottle with a pump. I like that it's formulated without sulfates or parabens and includes ingredients that protect color and smooth split ends. It's a very effective product if you're looking for something lightweight that visibly improves hair texture

I love how this serum smooths frizz without weighing my hair down. It gives my ends a polished, healthy look and adds shine without any greasy feel. The scent is light and pleasant, not overpowering. I use it on damp and dry hair — works great both ways! A little goes a long way, so the bottle lasts. Definitely a staple in my routine now.

Kristin Ess Working Serum is one of those products that just makes your hair do what you need it to do. I usually use it on dry hair after styling to smooth everything out, tame frizz, and add a soft, natural shine without that heavy, greasy feel. It’s super lightweight and gives your hair a polished look.

My sister in law living in Switzerland is very appreciative.

THIS HAIR SERUM IS THE BEST IVE USED! It smells so so good and one use on damp hair makes my wavy frizzy hair tamed and incredibly soft. By one use my hair was smooth shiny and soft 2 washes later. I will continue to use this as long as possible. A little goes a long way!!

This is one of my go-to hair serums! I love how it makes my hair feel silky smooth without weighing it down or making it feel/look greasy. I love the way it smells too :)

I recently added the Kristin Ess Weightless Shine Working Serum to my hair care routine, and I’m thrilled with the results. This lightweight serum has noticeably improved my hair’s shine and softness without weighing it down. I apply it to damp hair before blow-drying and to dry hair to control frizz and add luminosity. Its versatile formula helps me achieve polished hairstyles, and its subtle fragrance is a nice bonus. It has quickly become an essential for keeping my hair smooth, healthy, and radiant.

I paid for this product with my own money. I have chemically relaxed hair and wanted to find a product that would protect my long, relaxed ends. I was especially interested in this product because it contains chitosan, a marine ingredient that brought me consistently good results in past hair, skincare, and oral formulations. Simply put, this serum felt crunchy. I don’t like to waste things, so I cocktailed it a drop of castor oil and smoothed it into my damp hair. The end result was passable, so I will continue to use it in this way until I finish the bottle. I will not repurchase.
