No.4 Bond Maintenance® - Shampoo

My favourite shampoo. Changed the way my hair looks and feels forever . Absolute must have .

Making my hair, hair again!

My hair was irreparably damaged with over processed chemical straightening. It had the appearance of coconut fibre due to the damage. I could not get a comb through my hair as it would break and fall even with oiling or other treatments, products including leave in conditioner setc. I remembered that Olaplex repairs bonds and purchased No 4 shampoo,5 conditioner and No 5 leave in conditioner My hair is much better with a regular regimen of oiling followed by shampoo and conditioner with No 4 shampoo & 5 conditioner. After my shower with my hair still wet I apply the leave in conditioner.

Purchase with Caution

DO NOT BUY!!! It made my hair fall out in big clumps. BEWARE !! This is coming from a licensed cosmetologist of 8 years!!

My hair is looking so healthy now

I picked a set up a month ago and the positive difference in my hair is noticeable. It's healthy looking, shiney, and the best my hair has felt in a long time. My sister asked what I was using. Found out she's using the same products!

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
