I have used this product for over 10 years and can't live without it. Every time I run out I get panicked and it's been harder and harder to find. I worry that at some point it won't be there! I have tried many different products (It's a 10, Paul Mitchell, Nexus, Alterna, Redkin, drugstore products, etc.) and nothing smooths/conditions my hair like it. I have very fine hair that also gets very curly and frizzy in humidity. I will use this product forever!

I tend to have a love-hate relationship with Rusk products. However, this one is a keeper!!! Leave in conditioners tend to impart either moisture or body (control); it’s rare to find one that helps with both. This product fits the bill. Dry hair settles down a bit- not perfect, but improved. Though what really excites me about this leave in is the control aspect. Straggle and separation of my fine, fly away hair has noticeably decreased; when I swing my head- it all flows together! Application amount is a matter of trial and error, but definitely key to obtaining the desired result. For example, on my fine, BSL hair I literally apply just a squirt. Then I rub my hands together and with a thin layer of the product remaining on my hands, I smooth it over my towel-dried hair from ears to ends. I’ve found it best to avoid the crown and root areas. I would recommend this product as long as you’re not heavy-handed because it can make hair greasy if applied excessively.

I love this product and I would buy it again. It makes my biracial hair very soft. It doesn't define but it definitely softens. I apply it to towel dried hair and let it dry completely. Then I blow-dry or flat iron and it comes out great, full bodied and soft. I love it. Jut be careful not to use too much. The idea is to coat your hair lightly not to saturate it. I love the smell also. It is so refreshing.

I love the scent and love how it instantly softens my otherwise thick coarse hair. Sadly one bottle doesn't last very long (I also have like 20 pounds of hair, so it could just be me). My hair naturally looks fried and damaged, even when I haven't been abusing it, and this product single-handedly rejuvenates my hair to looking healthy again. Love it and would absolutely recommend it.

I have been using this on and off for years. I have fine hair that is super dry and damaged. This is one fo the only products I have found that detangles my hair without weighing it down or making it feel greasy. The smell is really light and not overpowering. The bottle lasts a long time. I do not notice any smoothing effects (as the name implies). It just mainly allows me to get the tangles out of my hair and leaves it soft.

this works. i have thick damaged hair and it makes it softer/easier to straighten.

I used this for awhile then realized about half way through the bottle it didn't really do much. Garnier leave in or mane n tail work just as well for a fration of the price.

I really like this stuff. I use this when my hair is damp. I noticed it works better when I use less product than a huge amount. It's moisturizing and it keeps my hair smooth. The smell is amazinggggg. I find this inexpensive because it lasts forever. I'll be repurchasing.

I bought this product almost two years ago when my hair was shorter and curlier; I used it per instructions but was not overly impressed with the results. 6 months ago I had my first child and truly, my hair texture has changed from fine curly to fine wavy. My "curls" are much looser and more wavy, and the length is longer than before - down to the middle of my back. I took the Rusk bottle off the shelf & decided to give it another whirl for the fun of it and I LOVE IT!! Last night I washed my hair with JASON Thin to Thick shampoo and JASON Biotin conditioner, towel-patted my hair and added a small pea-size amount of RUSK Smoother leave-in conditioner and let my hair air-dry before pulling it up in a loose bun for bedtime. This morning I woke up to beautiful soft shiny frizz-free waves, and the weather is rainy and muggy today!! I can run my fingers through my hair and finger style for touch-ups thru the day. Fabulous product, I'm glad I decided to re-try it. continued >>

I used this for about 2 months

PROS: Smelled really good and is light weight

CONS: Didn't do anything for my relaxed 4C hair, didn't help with detangling either
