I absolutely love Olaplex No. 9! It leaves my hair feeling soft, smooth, and healthy without weighing it down or making it feel greasy. I use it before heat styling, and it helps control frizz while giving my hair a silky, polished look. A small amount goes a long way, so the bottle lasts quite a while. I've noticed my hair feels more manageable and looks shinier since I started using it. It's become a regular part of my hair care routine, and I'll definitely keep repurchasing it. Highly recommend for anyone looking for a lightweight heat protectant that actually makes a difference.

This is the holy grail of hair products. I am in my late 40s and have thin, dry, color damaged hair. My hair has been frizzy and I could only wear a ponytail and even in that it would become a tangled rat mess. I have tried 100s of dollars in products from Keratin hair treatments, Aveda products, Nexus, Pantene, Its a 10, blowouts EVERYTHING under the sun and nothing was working. I was ready to shave my head and start over. Then I found this and read soooo many reviews and said shoot all I have to lose is more money. So for my fine, thin, color/highlighted damaged hair I got the 4/5 shampoo and conditioner, weightless nourishing mask,#3 Bond building hair and the #9 Bond Protector. My hair is now SOOOFFFTTT, not frizzy even when it is humid out (I live in the desert) so not many humid days until recently. This is all in just 3 days!!! Day one I used the Shampoo and Hair mask with already noticeable difference, Day 2 and 3 I used only the shampoo and conditioner. I started with the small bottles at $30 each and I am so far very pleased and plan on once I run out getting the larger bottles. I will tell you that you need a very very small amount of shampoo, it goes a LONG ways. The conditioner maybe a nickel size amount as it also goes a long ways. When I first used this and was done rinsing my hair, it did not feel soft and I was thinking okay I am going to not have fun brushing my wet hair and it was going to be a waste of money. Boy I was fooled. even though my hair did not feel soft and slick after conditioning, the wet brush I use as always just glided thru my hair with such ease. I was like oh okay and then once I dried it I was completely shocked at the difference the first wash alone had made. There were no tangles and the entire day my hair has been smooth, soft and manageable! I say take your chance and get this product, I hope you are as happy as I am with this. I plan on tossing every other hair product away now that this is the only thing that genuinely works for my hair in a way that I have never experienced with a hair product before.

Second time buying this and I'll definitely keep buying it. I always try to grab it when it's on sale for Prime Day or Black Friday because it's such a good deal. This is a must-have for my crispy bleached hair. It makes my hair feel so much softer, helps with tangles, and I always use it before heat styling. I don't like running out of this stuff. Happy with this!

Very nice silky texture that doesn’t require a lot for long hair. Doesn’t work very well for detangling but like for heat protection and can’t feel on my hair so no buildup.

I have been using Olaplex shampoo and conditioner for about 5 months now. I was looking for something to help with my dry ends and frizz while growing out my natural hair color (dark brown with small strands of white, with a naturally white stripe in the front). I read the reviews. I really love the results from the shampoo and conditioner, so I decided to try this. Washed and conditioned my hair last night, then applied Olaplex No. 9 Bond Protector Nourishing Hair Serum. I noticed the results almost immediately. My hair usually goes frizzy whether I let it dry naturally or if I blow dry it. My hair was much smoother and less frizzy and is holding my style so much better! I didn’t have to use very much hairspray at all! I would definitely recommend this to anyone. I realize that the price is steep, and that some people said that they had to use more product than the directions say. The price is steep, but if you can afford it, it is incredible. As for the amount to use, as with any hair product, the amount to be used depends on length and thickness of your hair. That is only logical. This product truly made a substantial and noticeable difference in my hair, it’s softer, shinier, smoother, less frizzy (almost completely frizz-free) and my dry ends look sooo much better!

It feels nice and I could comb through my hair easily. The package felt light. I was thinking maybe someone returned it after using it, but didn’t seem to be the case since it took several pumps to get solution. I have long, chlorine lightened hair and it feels soft after applying it. It’s crazy how expensive a small container of product is, but that is across the board with other products too.

⭐⭐⭐⭐⭐ Estoy muy satisfecho con Olaplex No. 9 Bond Protector Nourishing Hair Serum. Lo compré con la esperanza de controlar un poco el frizz y mejorar la apariencia de mi cabello, pero los resultados fueron incluso mejores de lo que esperaba. Mi cabello es áspero, ondulado y algo difícil de manejar, y este sérum ha marcado una diferencia notable. Desde la primera aplicación noté que el cabello quedaba mucho más brillante, suave y manejable, sin esa sensación pesada o grasosa que dejan otros productos. El brillo se ve muy natural, como si el cabello estuviera realmente sano, no simplemente cubierto por un producto. Lo que más me gusta es que facilita muchísimo el peinado. El cabello se desenreda con mayor facilidad, se controla mejor y mantiene un aspecto ordenado durante todo el día. Además, ayuda a reducir el frizz, incluso cuando hay humedad, algo que siempre ha sido un problema para mí. También he notado que el cabello se siente más sedoso al tacto y luce más saludable con el uso continuo. Como protector antes del secador o de herramientas de calor funciona muy bien, ya que deja el cabello con una apariencia más pulida y menos reseca. Otro punto a favor es que el producto rinde bastante. Con una pequeña cantidad es suficiente para cubrir todo el cabello, por lo que el envase dura mucho tiempo. Además, no deja residuos ni apelmaza el pelo, algo que valoro mucho porque prefiero un acabado ligero. En combinación con otros productos de Olaplex, los resultados son todavía mejores, pero incluso por sí solo ofrece un cambio muy evidente en la textura y el aspecto del cabello. Sin duda volvería a comprarlo y lo recomiendo a cualquier persona que tenga el cabello seco, áspero, ondulado o con frizz y quiera conseguir un cabello más brillante, manejable, suave y con un acabado de salón. Ha sido una excelente compra y uno de los mejores sérums capilares que he probado.
