    • This stuff is magic
Style: Fine To Medium
This stuff is amazing and it doesn't make my hair greasy. I can go 4 days without washing. As someone who likes to lighten their hair I have some damage from all the product. This stuff helps tame my fly aways and adds some shine and softness back to my hair. It detangles it to make it easier to brush through. The longer you let it sit the better it works. The scent is nice but not overpowering. ... show more

    • Love this product❤️
Style: Fine To Medium
I’m really impressed with this hair mask. The texture is lightweight, so it doesn’t weigh down fine hair, but it still delivers a deep level of moisture. After using it, my hair feels soft, hydrated, and much more manageable. It smooths frizz, adds shine, and leaves my hair looking healthier overall. I also love that it rinses out easily without leaving a heavy or greasy residue. The subtle scent is fresh and pleasant, making it feel like a little spa treatment at home. It’s a great option for anyone with fine hair who still needs extra moisture without the heaviness. ... show more

    • Intense conditioning
Style: Fine To Medium
I purchased this brands shampoo and conditioner in the past and was able to choose a free sample which I thought was this product. I remember loving the smell of the sample and decided to purchase this deep conditioner after my other ran out. I wasn’t as in love the scent as I remember and wonder if I got a different one in the past. But this deep conditioner does work well and I notice my hair is much softer after I use it. Usually I use it to detangle the dreadlock that forms in my daughter’s hair because that’s the only way to break it up. I like the simple branding of this brand and the color of the jar is neutral and clean. It’s a bit pricy but I am a true believer in high quality hair products because I get highlights and don’t get my hair trimmed as often as I should. ... show more

Love this product. This is my second purchase. I love the smell and everyone compliments the way my hair smells. It washes out well and doesn’t leave my hair feeling slimy. I love how silky my hair feels when I use this and keeps my hair healthy and hydrated. I use this mask only once a month so it lasts a long time. I also use the OUAI shampoo and conditioner. ... show more

    • Can’t live without it now
Style: Fine To Medium
I have type 3A curly hair and have struggled with frizziness forever. Using this mask and ones from Olaplex makes such a drastic difference. My hair feels softer, less frizzy, shiny, and just healthier. I have to always have one in my hair care routine. It’s a must now haha I like to throw it on in the shower and I don’t use a conditioner before. I just shampoo and lather the mask on. I throw on a shower cap and wait about 10 minutes before rinsing it out. ... show more

    • A frequently repurchased item
Style: Fine To Medium
I have purchased this many times for my hair and use in place of a conditioner. It offers great hydration and shine but is still lightweight enough for my way/curly hair. I love that it is in a container like this so I can get every last bit of product out and it doesn’t have a pump that gets easily clogged. Smells good, lasts a long time and is worth the money! Make sure you leave on for 5-10 min so it locks in the moisture. ... show more
