From your dense wavy girl!
I’m in love, I have wavy, dense hair, and this has really been cleaning my scalp and hair, my hair is more on the fine side so I barley have to use any shampoo at all! I have noticed less split ends, and I love the scent of the shampoo! 10/10!!!

I only used this and the No. 5 twice and my hair felt awful. I have very fine straight hair but a lot of it and it made my hair feel weighed down and like there was residue left on it. It felt like American Girl Doll hair if you know what that feels like. I don’t think I used it long enough to experience the hair loss other people are experiencing but it made my hair feel terrible I don’t want to use it anymore. When I used another shampoo my hair felt normal again. I’m not sure if you need to have more texture in your hair or what because this formula is very rich and heavy on the hair.

Causes dandruff
I’ve never had dandruff in my life. I started using the shampoo and conditioner and BAM. Dandruff like crazy. I stopped using it and it went away. Don’t recommend

It's a miss for me
Thought it was good until it wasn't. I feel like I lost more hair than normal and it ended up weighing down my hair. I ended up returning.

Think before you buy
Honestly this product is overpriced and overhyped let me deinfluence you babes. This product was being flamed a few years back for having hair loss inducing ingredients and idk if that’s changed but everytime I’ve used this product I’ve noticed hair loss… so yeah be careful

The best shampoo for me.
With fine, color treated and mature hair, this is what keeps my hair healthy. I will not be without it. The conditioner is also a great find for me, personally.

Hairloss Reviews Are True!
MASSIVE hair loss. I wish I realized this before it was too late. After using this for two weeks I noticed my hair felt a lot thinner and the ends are fried. I will be returning.

Best Shampoo
Color Safe, Clean, and Hydrating. I love this shampoo. It's amazing to use after the NO 3 Bond Builder. It really cleans my hair without drying me out or destroying my color.

Olaplex believer
First time trying Olaplex and now I see what the hype is about. My hair is damaged due to years of coloring and heat, it has made it dry, frizzy, and bad split ends. Within one use of the system, I immediately noticed a difference in the look and feel of my hair. The ends even look way better! So smooth and silky and soft feeling! Makes such a difference and will definitely be my go to for now on. I did receive this complimentary for my honest review!

No. 4 Bond Maintenance™ Shampoo
Olapex No4
I pretty much use the full regime of Olaplex. I tend to have a rotation of 4 brands that I use. This is one of them. The 4P puple shampoo is great for my grey / baby highlighed hair. I tend to use this as a pre-shampoo to ensure my hair is clean. It works well with coloured hair. And provides a good base for when I add the 4P purple shampoo. the 4P lathers well. If I do not preshampoo it doesn't lather very well. SO i find that they work well together.
