My new HG smoothing spray!!
This is my new HG smoothing spray!!! If I blow dry my hair and style immediately (rarely happens) I don't have to worry too much about frizz but my hair holds a curl for days and the frizz just gets crazier as the days pass. Because of this, even when my hair has a nice curl, it never looks as good ...

Too harsh
The main ingredient is alcohol and it is way too harsh on my hair. First time I tried it I washed and conditioned with bars. I then let my hair air dry just a bit and sprayed the smoothing spray. OMG, I though I had a head full of split ends. Took blow drying and hot iron to get it under control. St...

Great Shine
Hair Type Straight Hair
[I received this product in exchange for my honest review] This product works great when I blow dry my hair. My hair is extremely frizzy but it has worked so much to make it more manageable with each use. The scent isn't the best but it is tolerable and it has helped immense with shine.

Smooths without leaving your hair greasy!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] My mom and I love this spray. It does such a good job smoothing my hair and making it less frizzy. It doesn't leave your hair feeling greasy and it lasts all day. The scent can be a little strong/overwhelming, but I kind of like it! Will continue to purchase!!

This might be for you
Hair Type Wavy Hair
[I received this product in exchange for my honest review] Full disclosure; on the back of the bottle, it's recommended to blow dry hair after applying the product. I do not blow dry my hair because I do not like to use heat on it. I was hoping this product would help my hair with natural humidity. The spray itself does not come out sticky, which I enjoy, and it was easy to apply into my hair. I wasn't a big fan of the scent and the overall result didn't change my frizzy hair much, but it might be a good solution for those that flat iron hair or blow dry!

Not 4c girl friendly
Hair Type Very Curly Hair
[I received this product in exchange for my honest review] My hair type: 4c, vey tight doily hair. I am prone to frizz As someone with 4c hair, it is very hard to find anti-humidity and frizz control products that work. Also, living in FL, my hair immediately swells This spray is in an aerosol can. It makes the consistency very light, but has a concetrated mist when sprayed. You definitely have to pay attention to how much of your section receive the product. You want an even coat on the hair. It has a sweet perfumey smell. I really like it! It helped my dry time go quicker than normal. I used a high temp dryer with comb attachment. As you can see, it did a great job blowing my hair straight in comparison to how it started. I wanted you to be able to compare sides. I gave it a low review because within minutes, my hair started to puff back up but not fully. I also did the water test and it curled back almost instantly. I would only buy this as part of my blowout and straightening stule, not as a stand alone product. As someone with thick, kinky hair, it doesn't last long if you're looking for a sleek style.



Love this smoothing spray!!
Hair Type Wavy Hair
[I received this product in exchange for my honest review] This smoothing spray honestly amazed me by how well it worked! It exceeded my expectations and helps control my frizz and leaves my hair soft and shiny without making it look or feel greasy! It keeps my hair looking nice and smooth just how I want it to be all day long, and it smells good too! I'll definitely be purchasing more when this bottle runs out!
