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.

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...

Great Overnight Serum for Dry, Damaged Hair
Hair Type Straight Hair
This serum has been so good for my hair, especially when it is feeling extra dry or overprocessed. I use a pump or two before bed and by the next morning my hair feels softer, smoother, and way less frizzy. It helps my ends look healthier without making my hair feel oily or dirty. I also like that it is lightweight enough to use during the day on dry hair if I need a little extra moisture or shine. Over time I have noticed my hair looks less brittle and feels stronger overall. It is a great product if your hair needs some extra repair between washes.
Second time using this

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!!!
