Excellent Shampoo

I was out of Olaplex shampoo and conditioner for about a month, maybe two, & noticed that my hair was unruly and falling out (splitting at the ends) faster than usual. I wash my hair daily and Olaplex is the only shampoo that I like to use since I wash it so frequently. My hair is now shiny and loo...

Low porosity/Coil/4C-ish hair girlies, stay AWAY!!

I will leave this review on all the products I used that caused HUGE CHUNKS of my hair to fall out on wash day after using them as instructed. I get a silk press about 2-3 times and year and before using their products my hair was mid-back length, thick, with voluminous layers. However, due to low...

Stronger, Softer Hair After Every Wash

By Cristina

Hair Type Wavy Hair

This shampoo cleanses my hair without stripping away moisture, and my hair feels much softer and healthier after every wash, it has a pleasant scent, and leaves my scalp feeling fresh. I've also noticed less breakage and frizz, while my hair looks shinier and feels stronger. A great choice if your hair needs hydration and repair. I received this product as part of a educational program.

A concentrated shampoo that leaves dry, color-treated hair s

By Veronika

From Dallas

Hair Type Wavy Hair

I've tried a lot of shampoos because my hair is very dry, color-treated blonde, and naturally porous, so I'm always looking for products that help repair damage without making my hair feel heavy. This shampoo has become one of my favorites. Since it's concentrated, you only need a small amount to create a rich lather, and it cleans my scalp really well without leaving my hair feeling stripped. After rinsing, my hair already feels softer, and when I follow with conditioner, the results are even better. I noticed less frizz, more shine, and my hair feels stronger and much easier to brush. It also gives my hair nice volume while still keeping it hydrated, which is difficult to find with bleached hair. The scent is fresh and pleasant without being overpowering. Overall, I think this is an excellent shampoo for anyone with dry, damaged, or color-treated hair who wants healthier-looking, softer hair with consistent use.

Lathers well and makes hair feel super clean

Submitted 2 days ago

By Kelli

From Seattle, WA

Hair Type Straight Hair

Wow, this shampoo lathers SO WELL! I find that most shampoos poorly lather on my hair for some reason. I only need a small amount of shampoo to generate a lovely lather, and it feels so cleansing. I love that this shampoo focuses on strengthening my medium-thick hair, and repairs damage as I use heat styling and color treat my hair. When used with the No 5 conditioner, it leaves my hair feeling incredibly soft and shiny. I have noticed less breakage too which is fantastic! I also enjoy the scent which isn't too strong and is pleasant, with notes of grapefruit, mint, ginger, and sage. It is refined and not artificial smelling at all. The bottle is easy to use and looks great in the shower. I received this product as a part of an educational promotion.

I have very wavy and frizzy hair and i was looking for a hydrating shampoo that would make my hair smooth and make my frizz go away. And the shampoo by Olaex does exactly that. I would highly recommend it to everyone that has wavy and frizzy hair because it has transformed my hair and makes it very hydrating
