Olaplex Nº.4 Bond Maintenance™ Hair Strengthening Shampoo: Repairs Damage & Defend Against Future Breakage | Hydration & Softness | For Coily, Curly, Straight, and Wavy, 250 mL / 8.5 Fl. Oz.

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.

Olaplex is perfect product range and I bought it because I had serious damage to my long hair. I bought this product and a couple of others from the range. My hair condition quickly improved. I think the at home treatments work out value for money compared to regular in salon treatments. I recommend Olaplex range especially when you have damaged or coloured/dry hair.

This is simply the best shampoo on the market. It has a very unique scent that is difficult to describe but it's a nice scent. Its not fruity or flowery, it's a kind of sweet citrus smell. The shampoo leaves your hair silky smooth and soft. It looks a little bit expensive at first glance but it's absolutely worth the money. You don't need to use much of it, it goes a long way!

Feel like it’s helping my hair to be in better condition

Honest review here. I'm growing my hair from a short bob and one side at the top is slightly heat damaged. I thought I'd try the pre treatment and shampoo to see if it helped first before I bought the conditioner and oil. I put the pre treatment on for 10 mins...then washed my hair twice with the shampoo (u need so little as it lathers like nothing I've ever know lol) I then used bed head heat protector (smells like strawberries and is very good!) - after the first use my hair felt thicker...glossier and in general just so healthy. Wasn't expecting it to come out so well tbh. So glad I bought it and yes worth every penny! If u thinking of buying it please don't hesitate. Game changer!

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!

One of the best shampoo I've used, smells sweet and nice! Have been using for a long time and bought again many times! Also I have recommend it to many of my friends～

Started using via my hairdresser as my hair is thinning/fuzzy due to chemo. I like the product though expensive, which I’ll continue to use.

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.

Hands down, this is the best hair product on the market. The UAE water had damaged my hair making it fragile and snap easy ( snapping off by the handful every day). Even with a water filter, it still wasn’t enough. After spending thousands of dirhams on other various products trying to make my hair stronger, I should have started with Olaplex from the very beginning. It took around 3 treatments to feel significant strength return to my hair. There is now a normal amount of loss. Even my hairdresser noticed the difference (and she uses 1 and 2 as part of my colour treatment when I get my hair done). I use 0 and 3 together as well as Olaplex Shampoo and Conditioner. It’s a small price to pay for big results. Very happy with this purchase and can’t recommend this product enough. A personal recommendation from me to you 🫶

C est bien l'original ...Il est top et le prix aussi !

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.
