No.4 Bond Maintenance® - Schampo

Saved my bleached hair

Honestly people say it has damaged their hair further and I believe them but for me it definitely saved my hair. I went FULLY blonde two summers ago and people thought I will never have texture or length again (rightfully so). 2 uses of this restored my extreme bleach damaged hair by like 75% and continuous usage brought the percentage up even more. For my hair this saved it.

Worst Shampoo !

Made my scalp itchy and dandruff. After wash , bumps on my scalp looks like blisters. Biggest mistake to buy this shampoo.

Great shampoo

I really love this product. I find it to be a little intense for every wash but it’s perfect for 2-3 times per month. It smells amazing and works so well with other Olaplex products! I would repurchase

Very disappointed

Awful, my hair got thinner and so dry it very bad…

Super Happy, so happy I finally found OLAPLEX!

I waited a couple months before writing a review. I know I have tried shampoos and conditioners that seem great at first, but after a few weeks let you down. I have been using OLAPLEX for over 2 months, and I think it is my favorite hair products ever, and I am 60. I love both the #4 & #5, they are concentrated not watery like so many hair products. I have fine curly hair, which likes to frizz easily, even when I lived in Southern California. I now use the #3 once a week, following with the #4 shampoo, & #5 conditioner, & #6 smoother, the #6 smoother is the first product that seriously helps with my frizzy hair, and I live in the PNW on an island. My boyfriend has even commented on my hair being soft, the first time in our relationship of over 6 years. I was using a more expensive product line before this, it wasn't anywhere as good as these products, and I couldn't understand why my hair was falling out terribly, I thought it was my anxiety, it was the hair products I was using Kevin Murray Young Again, it made my hair feel older and fall out, like seriously fall out, it started soon after starting to use it, wish I would have figured it out sooner. My hair immediately stopped falling out from the very first wash using OLAPLEX. I know these products aren't inexpensive, but I feel for the quality they are fair priced. I will be sticking with OLAPLEX, I couldn't be happier. I also have the #5 leave in conditioner, and the number #8, and #9 products, but haven't tried them yet. I wish you the same wonderful results I am having.

So much dandruff & grease!!

Causes so much dandruff & my hair was so greasy less than 24 hours. Normally my hair has barley any dandruff & doesn’t get grease for at least 3 days after washing. If your hair gets greasy easily I wouldn’t recommend

Expensive and ended up with tangled hair.

I bought this shampoo and didn’t not like how it felt on my hair.My hair was so tangled even with the conditioner.I regret buying this.

Works Great

I've been using and repurchasing for a little under a year with great results

Warning label

I’m pretty sure this product caused more damage and breakage to my hair. I have fine strands but a lot of it, it was frizzy and dry and gave this a try. It worked to tame the frizz and dryness but after about 3 months of use I have layers in my hair now not because I cut them in but because of breakage. When I went looking for a solution from professional stylist several told me that this product can cause this sort of damage. I think more research should be done on whether it’s safe for thinner hair and the company even considers putting a warning label on it. Very disappointing to use a product to help my hair health and it made it infinitely worse.

Too Intense For Thin Hair

Tried this product for 2 months, my hair is very fine and it just was too intense. Made my scalp dry or would always leave residue (even if I tried the shampoo twice method).

Feels nice and fluffy

Just used it and my hair feels fluffy and moisturized! Doesn’t leave any residue on my low porosity hair and I hope it strengthens it! Don’t know how long it’ll stay fresh but so far it’s amazing! Highly recommended and please like :)

Scalp acne

This product is not good. After about 2 weeks of using I found that I was getting a lot of scalp acne. The only thing I am using in my hair is this, so I know for a fact that this product caused it. The only reason I am giving it 2 stars is because it does leave my hair soft and ckeab but only for 1 day. Overall not good abd WAY too expensive. The price poibt is crazy for something that is not good. I started using Aussie and its WAY better tgan this.
