Directions For external use only. Do not ingest. Review: Does what it says really impressed - 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. Review: Amazing shiny hair every time!! - 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. ## Features - A highly concentrated, color-safe shampoo proven to reduce breakage and nourish hair leaving it smoother, shinier, and more manageable with every wash.

I use the hair mask (no 3) first I tend to leave overnight and use the shampoo and conditioner. It has definitely improved my bleached hair **Q: I’ve got really fine hair, will this be ok for it?** A: Hello - the idea of Olaplex is to strengthen your hair by building bonds, so I think it would be absolutely perfect for your hair. From experience, and I know this is going to sound like I work for Olaplex (I don't), but I have found that the shampoo and conditioner work amazingly together, and the number 3 is my favourite of their conditioning treatments. Also, I know it seems like they are expensive, but you honestly don't need to use much at all - I use mine at least once a week and I still have about a third of the bottles of shampoo and conditioner left 10 months later. **Q: Is thus shampoo only fir coloured hair** A: No it’s for all hair types. Uncoloured and coloured **Q: Is this shampoo sulphate and paraben free** A: Yes- its not just a shampoo though- set up by Doctors originally for people whose hair had weakened with chemo, it works brilliantly to rebuild your hairs bond, to strengthen. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does what it says really impressed *by M***. on 28 July 2026* I thought I'd try as it was a little cheaper at the time.

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! ## Frequently Bought Together - Olaplex No. 4 Bond Maintenance Shampoo, Repairs, Strengthens, & Nourishes All Hair Types, Adds Shine & Leaves Hair Feeling Soft, 8.5 fl oz - Olaplex No. 6 Bond Smoother, Leave-In Styling Hair Cream Treatment, Smooths, Conditions, & Strengthens, Frizz Control for Up to 72 Hours, For All Hair Types, 3.3 fl oz - Olaplex No. 8 Bond Intense Moisture Hair Mask, Adds Smoothness & Nourishes for Visibily Healthy Hair, For All Hair Types & Treats Damaged Hair, 3.3 fl oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/71282258-n-4-bond-maintenance-strengthening-shampoo-bond-repair-250-ml](https://www.desertcart.us/products/71282258-n-4-bond-maintenance-strengthening-shampoo-bond-repair-250-ml) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-08*
