Super

Produit qui tient ses promesses, on sent un vrai “avant/après”

great

Smells good, makes my hair soft, shiny, heat protectant too

Good

I put a pea-sized amount in my toweled dried hair every other day, and it helps keep my colored hair healthy.

Staple

This is one of my favorite leave ins, it makes your hair stronger and feels so healthy

Love this!

Absolutely love this product! I have fine, damaged hair and this has definitely repaired some damage! Love how it makes my hair look and feel, would definitely repurchase.

Smells nice

I have my hair dyed and I think this product helps to get it softer. I do like how smells, overall I don’t see huge difference yet, but so far I’m not disappointed

Très bonne surprise

Je viens d’acheter ce produit et je dois avouer que le hasard avait beaucoup à voir dans ce choix. 24 h après son application mais cheveux sont tout doux au toucher pas besoin d’huile capillaire pour rendre un peu d’hydratation…. À suivre

THE BEST PRODUCT IVE EVER BOUGHT

I saw someone on Instagram use this, and thought I’d give it a go and omg honestly changed my life! Last time I cut my hair was May 2025, and I went this week (March 2026) & my hairdresser as so shocked at the condition of my hair, I had NO split ends, no dryness… I literally just needed a trim & it’s all down to this product. I put a pea size amount on my hand, rub my hands together to evenly coat and apply the products to my mid to ends on damp hair before blow drying. I’ve gifted this to so many, my sister has poor quality hair & since using this she’s been getting so many compliments in work! They do a travel size also to try before you buy.

Saved my hair

My hair is naturally very very dark brown/black. After bleach damage for 6 years + damage from hair extensions my hair was fried and dead. This has brought it back to life. I dont even use a fancy shampoo but i do use the redken conditioner from this line. I think both of those products brought my hair back. Have repurchased a few times now bc i love it

Soft and Gentle!

I was very pleased with this leave-in treatment! It smelled so good, left my hair soft, and protected it from heat! Would buy again for sure.

Acidic Perfecting Concentrate Leave-In Treatment

a really nice finishing step for damaged or dry hair. It helps smooth frizz, adds shine, and makes hair feel softer without weighing it down. I like that it also offers heat protection, which is great if you style your hair often. A small amount goes a long way and leaves hair looking healthier and more manageable.

Acidic Bonding Leave In Treatment

This product is “the one product I can’t be without”.. it is the only think that controls my extremely colored, curly, and senior hair. It softens this brittle hair. I love and and one time I forget it after my shower, I wet and towel dried my hair again immediately so I could put it on my hair.
