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...

My hair feels healthier after every wash.
Hair Type Straight Hair
I've been using this shampoo for a while now, and I can honestly see a difference. My hair feels softer, looks shinier, and is much easier to manage. It cleans my hair really well without making it feel stripped or dry, and I've noticed a lot less frizz. My hair just looks healthier overall, and I actually look forward to using it every wash day.
I recommend this product
Hair Type Wavy Hair
Olaplex has been the game changer for my hair! My hair is kinda blonde and has chemical treatments Brazilian blow out and I was looking for good products that could help me with the damage caused by chemicals. The shampoo and conditioner has helped a lot and gives healthy to my hair letting it shine and smooth. I really recommend both shampoo and conditioner.
First impressions
Hair Type Wavy Hair
I received this product as part of an educational promotion. I've been using the Olaplex No. 5 Shampoo and I really like it! The formula is pretty thick, and it lathers up really well while still feeling super moisturizing. Since it's so thick, I found that it's best to add a good amount of water and really massage it into your scalp. If you just apply it in one spot without enough water, it can stay concentrated in that area. I also love that the scent isn't strong at all, it's clean and subtle, which I personally prefer. After washing, my hair feels so soft, hydrated, and healthy. Overall, I'm really happy with it and I'd definitely buy it again!
I couldn't be more grateful
Hair Type Wavy Hair
I couldn't be more grateful and happy! My hair is was very dry as I have been using chemicals products for straightening so it had been very damaged. Olaplex changed everything and let my hair very smooth, straight and shiny. I would buy again and recommend specially if you have chemicals in your hair
Leaves my hair soft and healthy
Hair Type Straight Hair
As a busy mom, I don't have time for complicated hair routines, so I was excited to try the Olaplex No.4 Bond Maintenance Shampoo. My hair tends to get dry and a little frizzy between washes, especially with how often I'm running around with my baby. After using this shampoo along with the No.5 conditioner, I noticed my hair felt noticeably softer and more manageable right away. It didn't strip my scalp or leave any residue, and a little product goes a long way. The smell is clean and not overpowering, which I appreciate. This has quickly become part of my regular hair care routine and I'll definitely be repurchasing. I received this product as part of an educational promotion
