Acidic Bonding Concentrate 24/7 Night & Day Serum

Genuinely one the of the best products I’ve ever used to keep my hair hydrated and silky soft in between coloring. Smells good and lightweight.

[This review was collected as part of a promotion.] This product has really improved the breakage I’ve been dealing with. I absolutely love the way it smells.

Love the smell of this product and how I can use this night or day. Really helps with smoothing my hair

This is a creme product similar to a leave in conditioner and would not be ideal for fine hair. This is not a “serum”.

I use this almost every night and it has made such a difference! My hair feels softer and stronger even with it getting dyed every few months

I have dense, coarse wavy/curly hair (2c-3a) that is color treated from the mid lengths to ends. This product smells good and felt okay, it was very lightweight. I used the product consistently and used up the whole bottle. I have also been using it with the Acidic Bonding Shampoo & Conditioner as a system. I don't really think this is a product for people with dense or coarse hair. I had to use SO much to feel like there was any difference being made, like 6-8 pumps or more. I liked the consistency but it didn't really feel like it was doing anything. I applied it to my partner's hair and it seemed to soften it slightly upon application and reduce frizz. He has a lot of very fine, soft hair almost like baby hair. His hair is wavy, with more defined waves/curls at the back, probably a 2b. He has virgin, undamaged hair while I have chemically processed hair (bleaching, semi, demi, and permanent dye use in the past). I honestly don't know if this did anything at all. Certainly not worth the astronomical price point. I had been looking for a serum to use at night, similar to the kerastase genesis serum. I had instant results with the kerastase product and didn't see any differences with this.

I use this stuff consistently sometimes in the morning and at night. My hair is growing and my ends are not breaking off. You do not need a lot as it has a thick consistency. That's saying a lot as well as I have extremely thick hair

I absolutely love this serum! I use it daily, especially on the days I don’t wash my hair, because it nourishes my hair and leaves it feeling smooth and refreshed..

I'm unsure on how to use this product correctly as my hair is picky with products.

I use this stuff constantly. I put it on at night and sometimes in the morning if my ends are dry. It leaves my hair soft and calms down my frizz. I have noticed less breakage as well.

[This review was collected as part of a promotion.] I use this on my very curly hair. It helps to reduce the frizz, keeps it manageable and I use it on my ends to refresh them. So far I haven't had a negative issue with it.

Leaves my hair nice and soft. I use 3 pumps on each side of my hair morning and night.

Can definitely tell a difference with just one use

This smells amazing! I've only used it three times so far (overnight), but I can definitely tell a difference. I have 3c to 4a curls that I've bleached to the point my hair was full of split ends, frizz, and my hair wouldn't look good for more than two days. Now my curls stay more defined longer, with no split ends and significantly less frizz. 10/10

Smells amazing! Can be used on dry or wet hair. Really nourishes my hair.

[This review was collected as part of a promotion.] Best serum on the market! About 8 mos ago I had my my hair done. I have all over color with chunky blonde highlights. Unfortunately the lady ruined my hair and my hair was damaged and broke off every where. I started using this serum every night before bed I would apply 2 to 3 pumps and then also the day before wash day I applied 3 to 5 pumps. And I would brush it . Let me just say this stuff has transformed my hair. Its growing faster, healthier and all the damage has been repaired. I highly recommend this product.

[This review was collected as part of a promotion.] So have fine, straight hair with a lot of blonde highlights and my hair can get dry to the point that even a hair mask does nothing. I work the serum into wet hair and blow dry. It completely brings my hair back to life, leaves it super soft and smooth. The scent is light and I find it to be pleasant. It's a smallish bottle but you dont need a ton, just distribute it well! You can also use it on dry hair and it still works so well and doesn’t make your hair look oily! All in all, I love this product and feel like you would too if you were to give it a try!!

[This review was collected as part of a promotion.] Great for curly hair. I use on dry hair helps hair feel healthy

I have natural curly hair. My hair was getting fuzzy and knotted at the ends started using this product and I’ve had no problems

Makes my hair soft and smells wonderful! I use everyday

I put this on the ends of my hair and my hair does not get frizzy!!!

[This review was collected as part of a promotion.] Packing was okay and as expected. When applying to the hair it did leave some residue. It definitely added shine to the hair but I still have frizz.

I love how this product makes my hair feel so strong and soft. I haven’t been able to find something quite like it.

I have tried every product known to man. THIS is the only product that makes my frizzy blonde hair beautiful. I have even used the WOW products and haven't had results like I'm getting from this serum and the Acid Bonding line.

I have very fine fragile hair. This product has definitely helped my hair keep from breakage.

Probably my favorite addition and I consider it a must have daily serum. On my 2nd bottle now!

It is a lightweight serum. It didn't weigh my hair down. I used it to tame the frizz on my curls the next day.

[This review was collected as part of a promotion.] I use this after every shower. I have noticed a huge difference in breakage and damage from blonde. I love that it is a heat protectant as well. Does not feel heavy on the hair.

Hair feels much smoother less tangles more shine !!

[This review was collected as part of a promotion.] I use this every evening on dry curly hair. It has helped with split ends
