Acidic Bonding Concentrate 24/7 Night and Day Hair Serum, Bond Repair for Damaged Hair

I use this every night before bed with a silk bonnet and my hair is super soft in the morning. My hair definitely feels healthier.

This whole range is fantastic and this is WAY better than the Keratase Overnight one. And this also smells amazing too. Gives me silky soft hair virgin like hair with a light touch. No heaviness. Unlike the Kerastase Magic Night which weirdly makes my hair dull and dry! LOVE THIS!!! Buy the whole range - hero product is the Acidic Bonding 5 minute Mask 16% and better than K18 I’d say.

Great product 👍🏼

Love this, quite expensive but makes my hair feel so nice

Great for my hair and has certainly made a difference leaving no residue

Only been using a few days after bleaching hair at home and it’s made a big difference feels much softer

My product arrived perfectly in the box with the instructions, v excited to try it out. I was in between this and another from WOW hair, and having used Redken before, this was absolutely not what I expected from them. It’s a rather thick viscous texture of white colour, meaning you can easily overuse if you’re more careful. It weighs the hair down, my hair was not any shinier, only the ends seemed to look a bit mended up for the day, but lost its effectiveness throughout the day. Also made my hair more prone to knotting and feeling dirty, oily, even though it’s meant to be a lightweight serum, it’s more like body moisturiser really. Probably need to use more to see if there’s a right way of getting results, but I read all instructions and thought it was quite disappointing, especially given the cost. I tried on both dry and wet hair and obtained same results. I’d go for the competitor brands next time.

This product is wonderful—it leaves my hair silky smooth and has a beautiful scent!

Consigliato per chi ha capelli secchi. Li rende morbidi e molto profumati.

Perfecto estado, entrega en fecha. Muy buen producto, recupera el cabello 10/10

worth the price tag I have frizzy hair I've used shampoo/cond this roduct really tames ends without leaving curnchy feeling

Really good serum, does not add weight to my curls . Use two pumps each side at night, then make a bun with my hair before sleeping.

Ho i capelli stressati da tinte e piastra e questa linea è stata una vera salvezza! Dopo poche applicazioni ho notato subito capelli più forti, morbidi e luminosi, senza l’effetto crespo che avevo prima. In più ne basta pochissimo prodotto, quindi dura anche tanto. Profumazione buonissima. La ricomprerò sicuramente: super consigliata a chi ha capelli danneggiati e sfibrati!
