Rated 4 out of 5 by from Love I really like this product. I love and hate that it’s a spray bottle. I spray into my hand then apply to my hair. Otherwise it’s a bit too concentrated in one area. Adds glass like shine and I love that it has heat protection!

Rated 5 out of 5 by from Only use alongside full line You only wanna buy this if you’re getting the whole system. This isn’t really for retail, just professional as a mini Neese smoothing keratin blowout service. You must use all the products together like intended. And it’s a really good deal if you can get them on sale and it doesn’t add much time to your service.

Rated 3 out of 5 by from Smell is awful Doesn't weigh hair down however I did feel like I made hair look a little greasy. Helped with smoothing and humidity resistance. The whole line has an off smell to me,

Rated 5 out of 5 by from Lasts long After using it a few times I do notice a difference! It does help keep the shine and maintain frizz and curls. Has a thick consistency

Rated 4 out of 5 by from Wonderful This is wonderful for smoothing while styling. I wish the scent wasn’t as strong. It has a little different smell, would love to see that change

Rated 5 out of 5 by from Pleasant surprise I've been using this system for a few weeks now and I can honestly say my hair feels sleeker and more manageable. I live in a high humidity area and I can tell a difference in the smoothness of my hair after being outside. I also love the scent of these products!

Rated 5 out of 5 by from Sleek System! Amazing Sleek Serum to go with the Keratin alpha sleek anti- Frizz collection! Works well in conjunction with the rest of the system. Being someone who has frizz prone hair this is definitely a keeper! I did receive this product in exchange for my professional and honest review.
