N°.4 Bond Maintenance™ Strengthening Shampoo | Bond Repair, 250 mL

I thought I'd try as it was a little cheaper at the time. I was sceptical but after a few washes it really does make my hair soft and silky. I have thick fine coloured hair so it can be a little dry but this makes it really shiny. Really recommend. Wish it wasn't so expensive but you only need a small amount so it probably lasts longer than high street brands. I would buy again.

I actually ordered the shampoo by accident as I was meant to order the pre-bonding shampoo treatment only Plex number three however I was extremely impressed with the shampoo. It has lasted me quite a while as I use it in between to my normal shampoo but it works very well with other Ola Plex products on the market. It smells super great and is soft and smooth in my hair. There is a lot of product in the bottle and will last you a long time the brand is a quality brand so I expected nothing less from this shampoo.

My sister bought me a sample gift set for Christmas. I’ve seen this everywhere but never bought it because of the price. I caved in and purchased the shampoo and conditioner. I can honestly say it is worth every single penny. You only need the smallest amount, so will definitely last. My hair feels amazing, it was in really bad condition where I’ve died it. It feels so healthy and alive. 100% recommend!

Amazing item

Great product. Left my hair feeling really strong and gave it a shine, lost a star due to the price being quite high but it does what it’s supposed to so if you don’t mind a higher price point then it’s a good product.

Use this all the time

Absolutely loved it, you only need such a small amount will definitely be my choice from now on

Olaplex No. 4 has made a real difference to my hair., I have been using it now for over a year. After just a couple of washes, it felt much softer, smoother, and had a noticeable shine. My hair is usually a bit dry and not too healthy, but this shampoo left it feeling nourished and far easier to manage. You only need a small amount as it lathers up really well and the scent is clean and subtle. It is a bit on the pricier side, but the quality and results absolutely justify it, given that you only need to take a small amount and it lathers up well so it can last quite a while. I’ll definitely be sticking with it.

Very good shampoo! I'm delighted! It works great on bleached hair! Thanks to the seller for a great product!

Très bon produit , me fait des très beaux cheveux, franchement j’étais étonnée

I love olaplex, I always get compliments on my hair that it looks so healthy

So I've had this weird scalp condition where I shower with the most gentle of shampoos and most moisturizing of conditioners, my hair drys, and my scalp gets tight and itchy and then second day my hair is greasy and I have dandruff. Super weird. Been happening for the better part of two years, and have tried all the dandruff shampoos which made it a million times worse, then I tried all of the moisturizing shampoos and even the no poo-shampoos. Nothing worked. I decided to buy this shampoo because I had bleached half my hair from the ends to about the middle of my medium length, thin hair, and it was starting to look... Sad. Thought if this could at least fix some of the damage of the bleached parts, I'd be happy. This not only added moisture and shine and life to my hair, it completely fixed my scalp condition?! Like. If I had known it would moisturize my scalp without making it greasy, and completely stop the itching... I would have bought this years ago. It's a small bottle, but you only need a little bit and ... No more itching.... I'll never buy anything else ever again. So impressed and happy. Also it smells great. Worth every penny.

With my chemically treated hair, it is a must to do home maintenance at least once a week. I’ve tried many brands in the past years. Olaplex has been the single easiest solution for my hair treatments at home. A simple 3-step solution once a week is enough to keep my hair healthy.
