Acidic Perfecting Concentrate - Leave-In Treatment

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

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.

Amazing product

That’s my third tube last for ages also spreads nicely onto the palms smells just like the rest of the line “clean citrusy”. Got a heat protectant so it’s a double win. Texture light/creamy/balmy

Fonctionne bien

J'en suis à mon troisième lavage, et le produit rend mes cheveux plus doux et plus discipliné, il sent très bon aussi

Great

Works really well the soften and visibly improve hair texture/health.

Gut

Sehr klebrige Textur, das muss man mögen. Ich mag die Resultate aber. Finde es nur relativ schwierig, dieses Produkt in meine Routine zu integrieren.

Very good

I love this it smells amazing too. I bought this twice already and will be buying again.

Great product super nourishing

Argh I love this leave in! It’s a favourite of mine- leaves hair and ends so nourished without weighing them down! You do need to use a lot of it if you have thick hair but totally worth it.

I have recently bought and after 2 uses my hair has felt so much softer
