Game-Changer for Blonde Hair!
I’ve been using the Kerastase Blond Absolu Hyaluronic Acid Serum for a few weeks now, and I’m absolutely in love! As someone with blonde hair, I’m always looking for products that hydrate, repair, and keep my hair looking vibrant without weighing it down. This serum does all of that and more. The formula is lightweight yet incredibly nourishing. It adds a beautiful shine and makes my hair feel soft, smooth, and healthier. I’ve noticed a significant reduction in frizz, and my blonde highlights look more refreshed and vibrant. It also has a pleasant, subtle scent that’s not overpowering. What I love most is that it doesn’t leave my hair greasy or heavy, and a little goes a long way. I apply it to damp hair, and it helps with detangling and adds a nice, silky texture. Overall, this serum is a must-have for anyone with blonde or bleached hair. It truly works wonders and is well worth the investment!

Ideal for blondes — leaves hair soft, shiny, and protected The Kérastase Blond Absolu serum surprised me from the very first use. I have blonde hair, and it tends to get dry and dull, but this product truly makes a difference. The texture is lightweight, doesn't leave my hair greasy, and absorbs incredibly fast. After applying it, my hair is much softer, with a beautiful shine and without that yellowish tone that often appears. It also helps a lot with frizz and protects my hair from heat, so I use it before straightening or blow-drying. It's a bit pricey, but totally worth it because you can see the difference from day one. If you have blonde or bleached hair, this serum is amazing.

Works pretty good
The first one I ordered had no scent and seemed thicker than the one my stylist used. I suspected a bad batch or counterfeit so did a replacement order. Happy to receive a good bottle the second time around. Just like the one my stylist used. Nice scent and leaves my hair soft and smooth. Apply to damp hair then blowdry. Personally, I think the price is a bit high on this small bottle but it does work well.

Quality hair serum
I had to have surgery that required a long recovery. My hair became so fine and frizzy during this time. I tried other hair serums/products with disappointing results. This hair serum is different. It is easy to apply and I’m loving the results. My hair has more volume, is so soft, manageable, and healthy again.
