Smells great and smoothes hair
I received this product for free in exchange for my review. However, I was impressed! I recently tried the Hair Acidic Bonding Concentrate 24/7 Night + Day Serum, and I'm thoroughly impressed. Compared to other hair serums I've used, this one stands out for its versatility and long-lasting benefits....

My hair needs help but this wasn't the help for me
I was really excited to receive my free bottle of Acidic Bonding Concentrate because my winter hair desperately needed it. Between split ends, color damage, and dry, indoor air affecting my wavy hair, I was eager to try this product to try and repair my hair. First off, the packaging was pretty, bu...

I've been using this serum both on damp hair before styling and on dry hair before bed. I apply 1–2 pumps, focusing on mid-lengths and ends. The texture is lightweight and absorbs quickly without leaving any greasy or sticky feeling. During the day, it helps control frizz, adds shine, and makes my hair look more polished. At night, I use a small amount on dry hair, and by morning it feels softer, smoother, and less tangled. I've noticed less breakage and my ends look healthier over time. What I love most is that it protects while still keeping the hair lightweight and full of movement. It doesn't weigh my hair down and works beautifully with the rest of the ABC line. The only thing to keep in mind is to start with a small amount, especially if you have fine hair. Overall, this serum became a staple in my routine, and I would definitely repurchase.
I love this product!!
Definitely has stopped any breakage from me going black to blonde this time around. It brings life to my hair, Will be repurchasing always!!!
Excellent product
I got this as a free sample , immediately fell in love with this product, it made my hair shiny and silky, now i'm buying a full size
Influenced and thrilled by it
Hair Type Wavy Hair
Initially purchased in response to being influenced by the Abbey Yung method. My naturally gray hair has been suffering with extreme breakage and just felt brittle. Within two uses I felt the difference. Will be repurchasing.
Best product on the market
Best serum on the market! About 8 mos ago I had my hair done. I have an 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.
