Rated 5 out of 5 by from Great addition to Extreme Length shampoo Helps seal ends and hair shaft to keep from frizzing. Does not weigh the hair down. Slight, natural scent. Cosmetologist for 39 years. Love the Extreme Length products.

Rated 4 out of 5 by from Pretty good I didn’t notice a drastic change, but I did notice it helped with my split ends! I also don’t use it religiously like I should be, sometimes I use it with a different shampoo/conditioner line so that might be the case! This whole Extreme Length line also smells SO GOOD!

Rated 5 out of 5 by from like WOW This stuff is where it’s at. I really didn’t like the shampoo or conditioner of this line but this stuff is so worth it. It really coats the hair in a protective layer of silky goodness and is so soft even before drying your hair. I would usually put the product in and let it sit while I got out of the shower and did my lotion and stuff. I have 2c curls so nothing crazy but it definitely did not weigh my hair down, just gave it a really silky soft feeling when it was dry. I’m going to be using it with my unite shampoo

Rated 5 out of 5 by from My favorite product for damaged hair by far Favorite for color damage . Not too thick so it doesn’t weigh hair down and a little goes along way.

Rated 3 out of 5 by from A little goes a long way I like this product but don't love it! It smells really great but unfortunately it makes my hair feel a little sticky. I find that if I use less of this product it works better for my hair type.

Rated 3 out of 5 by from I like it but wouldn't buy again I feel like this product is very heavy for my fine/medium hair. I have used olaplex 6 before I feel it compares but is thicker. A little bit goes a long way I just don't like how it weighed my hair down I prefer more light weight leave ins. Would be great for thicker/ curly hair!

Rated 5 out of 5 by from Nice product A little of this goes a long way! I mostly apply it mid length to ends and it works very well. My hair feels thicker when using this with the shampoo and conditioner!

Rated 5 out of 5 by from Lightweight sealer This product is a light weight sealer that seals your hair for styling or for the day . It is a leave in product so you don't have to rinse it out . The picture shows the consistency so you know it will absorb fast and doesn't ruin your clothes .

Rated 4 out of 5 by from Pretty good! I don't feel a huge difference in my hair with or without this product. My hair has felt so nice with using the shampoo/conditioner I can't tell if this is doing much!
Date published: 2023-05-28
Rated 5 out of 5 by from I recommend! This dealer is like an extra boosted version of a leave in conditioner product. It's a thicker consistency and holds in the hair well. It does not make the hair feel greasy or residue. I really Love this to follow with the shampoo and conditioner set. I get My hair professionally colored therefore I love The extra help with products to keep my hair healthy.

Rated 5 out of 5 by from Extreme Length leave in treatment I have been using this leave in treatment for a week, after using the shampoo and conditioner from this line. After towel drying my hair I apply this through my hair till the ends. I have definitely seen a difference in my hair after a week, so much softer and more manageable so it's easier to brush and detangle. My hair has been feeling great so far.
