How to Use
Rated 4.67 out of 5 stars
Found this to be great for setting my style after using the rest of my products. I use a curl enhancer on my wavy hair and diffuse a little, then blend this with water between my hands and apply gently. I then diffuse or air dry till dry and scrunch out the crunch. Curls for days.
Be careful not to use too much as it can leave hair very crunchy. I made that mistake the first time I used it and wound up washing my hair again. I make a cocktail with a tiny bit of Silk Therapy Lite and apply to wet hair and air dry; I do not blow dry my hair. The second time is used less product and it was better. So I'm still trying to get the amount right. Gives a nice shine.

This product gives me amazing hold! It forms a hard cast that can be scrunched out for wavy/curly hair. Leaves my hair defined and frizz free.

I have a pretty loose curl pattern paired with fine, low porosity, low density hair. This stuff has done the best out of anything for helping to enhance my curls and provide good hold that last more than a day. I like to rake then scrunch this into my very wet hair after adding in my leave-in moisturizer. Afterwards I'll scrunch with a soft t-shirt then either plop or diffuse my hair. Diffusing seems to yield the best results, but I'll plop if I washed at night or am being lazy. I don't like to just let my hair air dry with this product as it is heavy enough to weigh down my hair when I don't manipulate it while drying. This creates a very strong cast, so you do need to scrunch it out once dry, but once you do your hair is soft, shiny, and defined but still has some volume to it. I bought a different gel by shea moisture after I ran out of this one because I was hoping for something easier to find and cheaper, but it just does not work as well so once I finish my current gel I am going back to this one. If you really struggle with keeping hold or definition then I highly recommend you try this, it's pricier than drug store but a little goes a long way so the bottle last for several months.

Being that the name is Rock Hard I was a little afraid of how hard it would be. This is such a great balance of hold with shine. I don't feel crunchy and can manipulate it without messing up the style. I have a pixie cut and this is a great product for it!!

My holy grail product for wavy/curly hair!
Sam from Prov
It has great hold and makes my curls look so smooth and silky after I scrunch the crunch. But the texture of the gel is weird and super thick, it feels like congealed silicone :-/ and I feel like it weighs my hair down
Patty from Ft worth tx
It is very inconsistent on how it is made. And very expensive. I purchased
Another one and it is how it should be. I have one left at home that I can not use.
Jill from Oregon
I can get 5-6 days with this on my naturally curly hair! I love it and am so glad I found it again!
Tina from Washington
This gel it's absolutely amazing it does have a really hard hold so it will leave a nice cast on your hair but you just got to scrunch it out
amyzan from Kansas City metro
This product has to be scrunched out once my hair dries to make soft curls that last for days and resist humidity. No other gel performs like this one. It's amazing and worth every penny.

I do like this product, however the image does not match what was delivered to me. I find it deceiving. Fix the image, then I will bump up the rating.
Shelby from USA
This is the best hair gel ever! It holds my thick, naturally curly hair perfectly without flaking. It adds shine and body. The high quality ingredients actually protect my hair and never leave it dry or heavy. It's more expensive than drugstore products, but worth it. Holy grail for me! Please don't stop making this!

I have been using this hair gel for a very long time and will continue to repurchase it. It is my holy grail product. I have below the shoulder fine texture curly hair that is pretty thick (3B curls). This product gives me good curl formation and really helps cut down on frizz. I use it on soaking wet hair and rack the gel from roots to ends and then scrunch. I usually air dry and just scrunch out any crunch I might have. My hairs feels soft, curls defined and plenty of shine. When my hair is extra dry, I use a leave-in conditioner and then apply this gel after that. Or, I will just use it on its own when the weather is pretty humid. It does have a very light herbal scent but nothing strong, very subtle. It is a clear gel that is fairly thick, not runny at all. A+++
