Reviews

Light and refreshing

"I really like this leave-in, it is so light, has a clean tea scent that feels super refreshing. The texture is weightless, so it doesn’t make my hair greasy or heavy. I use it both on damp and dry hair, 5-6 sprays in the morning and the hair feels hydrated and refreshed. I like it for this not oily finish and because it always leaves my strands soft and smooth."

Fioreviewer (4/5)

Works well for curly hair

"I love how this leave in conditioner leave my curls still looking fresh and tame. It has a very mild scent but it smells fine. It comes packaged as a spray which feels a bit tedious for someone with long, curly hair. I would recommend this product as it does not disappoint in conditioning and detangling."

Marilyng61 (5/5)

Light and clean scent!

"I absolutely love this leave-in conditioner! Only have used a couple times so far but It makes my hair soft, shiny, and easy to detangle without feeling heavy or greasy. The scent is light and clean, and I’ve noticed my ends look so much healthier after using it regularly. Plus, it’s color safe and gives my hair great protection when styling. Definitely a new favorite in my hair routine!"

Jordanr56 (5/5)

Smooth hair

"This leave in conditioner is very nice. It detangles and leaves my hair very smooth. A couple of sprays is all you need. The smell of the product is very nice also, fresh and reminded me of a hair salon, I enjoyed it. The container is very cute, reminded me or a lab beacon. It’s a good product."

Lbotel2 (4/5)

Conditioner spray.

"This is my first time using a conditioner hair spray, and I’m really impressed. I love the convenience of being able to apply it to both wet and dry hair. After using it, my hair feels smooth, soft, and lightweight, with no residue or mess. The scent is light and pleasant, and the packaging design is adorable. Overall, a great product at a fair price"

Jolee88 (4/5)

"Good product"

Leizbeth (5/5)

Great product!

"Great product! With curly & frizzy hair, it is a must to have leave in conditioner and detangling products. I loved the packaging, how you don’t really have to get your hands sticky with the product , just spray and brush. I really wasn’t a fan of the smell, it had a fresh leathery smell but loved how effective it worked on my hair and my baby girls hair as well."

Leanie89 (4/5)

"Ive been using it for years and i cant get enough of it"

Victoria (5/5)

💚 Lightweight Detangler That Smells Amazing and F

"I really like the packaging on this product, it’s simple, sleek, and easy to hold. The spray works evenly and gives just the right amount each time. The texture feels like a light conditioner, not too thick or greasy, and it absorbs nicely into my hair without weighing it down. The scent is amazing, fresh and clean without being overpowering. It softens my hair, helps detangle, and leaves it feeling healthy even if it doesn’t always look it. I use about four sprays (two on each side) and it makes brushing through so much easier. My only complaint is that it runs out fast, but overall it’s a great everyday product."

Briellelah (4/5)

Perfect hair repair

"I thought this perfect repair leave in conditioner helped make my hair softer and split ends less noticeable. It didn’t have an overpowering scent. I thought the quality was good and it lasted awhile."
